Cisco StackWise Technology for Stackable Resiliency
Cisco StackWise technology is a stacking architecture optimized for Gigabit Ethernet. This technology is designed to respond to additions, deletions, and redeployment while maintaining constant performance. Cisco StackWise technology unites up to nine individual switches in a single logical unit, using special stack-interconnect cables and stacking software. The individual switches can be any combination of Cisco Catalyst 3750, 3750 v2, and 3750-E Series Switches. The stack behaves as a single switching unit that is managed by a master switch, chosen from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption.
Cisco StackWise stacking creates a 32-Gbps switch interconnection. Stacking does not require user ports. Up to 9 units can be stacked together for a maximum of 468 10/100 ports. Additional port combinations can be created by stacking together the Cisco Catalyst 3750 v2, 3750, and 3750-E Series Switches.
Cisco Catalyst 3750 v2 Series Software
The Cisco Catalyst 3750 v2 Series can be purchased with the IP Base or IP Services license preinstalled. The IP Base license offers advanced quality of service (QoS), rate limiting, access control lists (ACLs), and basic static and Routing Information Protocol (RIP) and OSPF routing functions. The IP Services license provides a richer set of enterprise-class features, including advanced hardware-based IP unicast and IP multicast routing as well as policy-based routing (PBR). The Advanced IP Services license, which includes IPv6 routing and IPv6 ACL support, is now included in the IP Services license. Upgrade licenses are available to upgrade a switch from the IP Base license to the IP Services license.
Configurable Cisco IOS Software
The Cisco Catalyst 3750 v2 Series can be preconfigured with a specific Cisco IOS Software release at the time of ordering. This option eliminates the need to reload a specific Cisco IOS Software release during deployment, thereby reducing deployment time and cost. The Cisco IOS Software release to be preloaded can be selected from a list of supported Cisco IOS Software releases, including the crypto version.
Cisco EnergyWise
The Cisco Catalyst 3750 v2 Series supports Cisco EnergyWise, which is a technology that enables monitoring, reporting, and management of energy consumption by end devices that are EnergyWise enabled. This technology enables companies to reduce their energy costs and carbon footprints. EnergyWise features enable you to:
Discover all Cisco EnergyWise enabled devices on the network
Monitor and report power consumption by these devices
Implement business rules to control power to these end devices
More information about Cisco EnergyWise can be found at https://www.cisco.com/go/energywise.
Power over Ethernet
The Cisco Catalyst 3750 v2 Series can provide a lower total cost of ownership (TCO) for deployments that incorporate Cisco IP Phones, Cisco Aironet wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE eliminates the need for wall power outlets for each PoE-enabled device and significantly reduces the cost for additional electrical cabling that would otherwise be necessary in IP phone and WLAN deployments. The Cisco Catalyst 3750 v2 24-port PoE switch can support Class 3 PoE or 15.4 watts (W) of PoE power on all 24 ports. Taking advantage of Cisco Catalyst Intelligent Power Management, the Cisco Catalyst 3750 v2 48-port PoE configurations can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between. Maximum power availability for a converged voice and data network is attainable when a Cisco Catalyst 3750 v2 Series Switch is combined with the Cisco RPS 2300 for protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages.
Redundant Power System
The Cisco Catalyst 3750 v2 Series access switches support the new generation of Cisco RPS 2300, which increases availability in a converged data, voice, and video network by providing transparent power backup to two of six attached Cisco Catalyst 3750 v2 Series Switches at the same time. The Cisco Catalyst 3750 v2 Series Switches are capable of reverting to their internal power supply without any service interruption. In addition, the Cisco RPS 2300 can be managed by a Cisco Catalyst 3750 v2 Series Switch that is connected to it.
Primary Features and Benefits

Cisco SmartPort macros offer a set of verified, pretested, recommended switch port configurations or templates per connection type that are easy to apply, enabling users to consistently and reliably configure essential security, IP telephony, availability, QoS, and manageability features with little effort and expertise.
Cisco Auto-SmartPorts automatically execute SmartPort macros based on the end-device type, such as IP phones, desktop computers, and WLAN access points.
Cisco Express Setup simplifies initial configuration with a web browser, eliminating the need for more complex terminal emulation programs and command-line interface (CLI) knowledge.
IEEE 802.3af and Cisco prestandard PoE support comes with automatic discovery to detect a Cisco prestandard or IEEE 802.3af endpoint and provide the necessary power without any user configuration.
Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment.
DHCP AutoInstall simplifies the deployment of a large number of switches by automatically downloading a specified Cisco IOS Software image and a configuration file from a Trivial File Transfer Protocol (TFTP) server. This feature can be used to implement an automated, or zero-touch, deployment.
DHCP Port-Based Allocation allows you to allocate the same IP address for a specified port. The feature allows persistent allocation of IP addresses to specified network devices.
Cisco IOS Embedded Event Manager (EEM) is a powerful and flexible tool for management and automation. This feature can be used to monitor network events and program automatic actions based on these network events. Policies can be defined through the CLI or through Tool Command Language (TCL) scripts and can be used in a variety of scenarios, such as automatic backup of a configuration file at a specified time or the triggering of an alert when traffic congestion crosses a specified threshold. Cisco IOS EEM requires the IP Services license.
Configuration Replace and Rollback simplifies configuration management by allowing you to roll back configuration changes. This feature allows you to replace a configuration file with a saved configuration file without a switch reload; up to 14 configuration files can be saved.
Automatic QoS (Auto-QoS) simplifies QoS configuration in voice-over-IP (VoIP) networks by sending interface and global switch commands to detect Cisco IP Phones, classify traffic, and enable egress queue configuration.
Autosensing on each 10/100 port detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps operation, easing switch deployment in mixed 10- and 100-Mbps environments.
Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.
Dynamic Trunking Protocol (DTP) helps enable dynamic trunk configuration across all switch ports.
Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel groups or Gigabit EtherChannel groups to link to another switch, router, or server.
Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP.
DHCP Server enables a convenient deployment option for the assignment of IP addresses in networks that do not have a dedicated DHCP server.
DHCP Relay allows a DHCP relay agent to broadcast DHCP requests to the network DHCP server.
IEEE 802.3z-compliant 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-T, and coarse wavelength-division multiplexing (CWDM) physical interface support through a field-replaceable SFP module provides exceptional flexibility in switch deployment.
The default configuration stored in flash memory helps ensure that the switch can be quickly connected to the network and can pass traffic with little user intervention.
Automatic medium-dependent interface crossover (Auto-MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight through) is installed on a 10/100 port.
Time Domain Reflectometry (TDR) helps diagnose and resolve cabling problems on copper Ethernet ports.
Enhanced Security
With the wide range of security features, such as ACLs, authentication, port-level security, and identity-based network services (IBNS) with IEEE 802.1x and extensions that the Cisco Catalyst 3750 v2 Series offers, businesses can protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation. These security features include the following:
IEEE 802.1x allows dynamic, port-based security, providing user authentication.
IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user regardless of where the user is connected.
IEEE 802.1x with voice VLAN permits an IP phone to access the voice VLAN regardless of the authorized or unauthorized state of the port.
IEEE 802.1x and port security are provided to authenticate the port and manage network access for all MAC addresses, including those of the client.
IEEE 802.1x with an ACL assignment allows specific identity-based security policies regardless of where the user is connected.
IEEE 802.1x with guest VLAN allows guests without IEEE 802.1x clients to have limited network access on the guest VLAN.
IEEE 802.1x supplicant on the switches can be used to authenticate switches on the network, thereby preventing unauthorized network devices from being used to expand the network.
IEEE 802.1x readiness check eases IEEE 802.1x deployment in an enterprise. This feature determines whether the client has an IEEE 802.1x supplicant by initiating an IEEE 802.1x ping.
Open IEEE 802.1x allows network communication to take place before IEEE 802.1x authentication. This feature is useful for preexecution environments (PXEs) and other applications in which network connectivity is required prior to IEEE 802.1x authentication. An ACL is used to allow traffic prior to authentication.
Flexible authentication (FlexAuth) can be used to determine the order of authentication methods on the network. For example, if the order is set to IEEE 802.1x, MAC authentication bypass (MAB), and WebAuth, the network will first try to authenticate through IEEE 802.1x, then MAB, and then WebAuth.
Multi-authentication (MultiAuth) enables up to eight users to authenticate through the same switch port. This feature includes support for multiple authentication methods, such as IEEE 802.1x, MAB, and WebAuth, and per-user ACLs.
Web authentication for non-IEEE 802.1x clients allows non-IEEE 802.1x clients to use an SSL-based browser for authentication.
Local web authentication allows non-IEEE 802.1x users to authenticate through a login webpage. The user enters the authentication information, such as a user ID and password, and is authenticated through an authentication, authorization, and accounting (AAA) server.
The local web authentication banner allows users to customize the authentication webpage.
Multidomain authentication allows an IP phone and a PC to authenticate on the same switch port while placing them on appropriate voice and data VLANs.
MAB for voice allows third-party IP phones without an IEEE 802.1x supplicant to be authenticated using the MAC address.
Cisco security VLAN ACLs (VACLs) on all VLANs prevent unauthorized data flows from being bridged within VLANs.
Cisco standard and extended IP security router ACLs (RACLs) define security policies on routed interfaces for control- and data-plane traffic.
Port-based ACLs (PACLs) for Layer 2 interfaces allow application of security policies on individual switch ports.
Unicast MAC filtering prevents the forwarding of any type of packet with a matching MAC address.
Unknown unicast and multicast port blocking allows tight control by filtering packets that the switch has not already learned how to forward.
Secure Shell Version 2 (SSHv2), Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSHv2, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions.
The Private VLAN Edge feature provides security and isolation between switch ports, helping ensure that users cannot snoop on other users' traffic.
Private VLANs restrict traffic between hosts in a common segment by segregating traffic at Layer 2, turning a broadcast segment into a nonbroadcast multi-access-like segment.
Bidirectional data support on the Switched Port Analyzer (SPAN) port allows the Cisco Secure Intrusion Detection System (IDS) to take action when an intruder is detected.
TACACS+ and RADIUS authentication enable centralized control of the switch and restrict unauthorized users from altering the configuration.
MAC address notification allows administrators to be notified of users added to or removed from the network.
Dynamic Address Resolution Protocol (ARP) Inspection (DAI) helps ensure user integrity by preventing malicious users from exploiting the insecure nature of ARP.
DHCP snooping allows administrators to help ensure consistent mapping of IP to MAC addresses. This feature can be used to prevent attacks that attempt to harm the DHCP binding database, and to rate limit the amount of DHCP traffic that enters a switch port.
IP source guard prevents a malicious user from spoofing or taking over another user's IP address by creating a binding table between the client's IP and MAC addresses, port, and VLAN.
DHCP Interface Tracker (Option 82) augments a host IP address request with the switch port ID.
Port security secures the access to an access or trunk port based on the MAC address.
After a specific time period, the aging feature removes the MAC address from the switch to allow another device to connect to the same port.
The Trusted Boundary feature provides the capability to trust the QoS priority settings if an IP phone is present and to disable the trust settings if the IP phone is removed, thereby preventing a malicious user from overriding prioritization policies in the network.
Multilevel security on console access prevents unauthorized users from altering the switch configuration.
The user-selectable address-learning mode simplifies configuration and enhances security.
Bridge protocol data unit (BPDU) guard shuts down Spanning Tree Protocol PortFast-enabled interfaces when BPDUs are received to avoid accidental topology loops.
Spanning-Tree Root Guard (STRG) prevents edge devices not in the network administrator's control from becoming Spanning Tree Protocol root nodes.
Internet Group Management Protocol (IGMP) filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port.
Dynamic VLAN assignment is supported through implementation of VLAN Membership Policy Server (VMPS) client functions to provide flexibility in assigning ports to VLANs. Dynamic VLAN helps enable fast assignment of IP addresses.
Cisco Network Assistant software security wizards ease the deployment of security features for restricting user access to a server as well as to a portion of or the entire network.
Two thousand access control entries are supported.
Availability and Scalability
The Cisco Catalyst 3750 v2 Series is equipped with a robust set of features that allow network scalability and higher availability through IP routing as well as a complete suite of Spanning Tree Protocol enhancements that help increase availability in a Layer 2 network.
Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST+), Uplink Fast, and PortFast, increase network uptime. PVST+ allows Layer 2 load sharing on redundant links to efficiently use the additional capacity inherent in a redundant design. Uplink Fast, PortFast, and BackboneFast all greatly reduce the standard 30- to 60-second Spanning Tree Protocol convergence time. Loop guard and BPDU guard provide Spanning Tree Protocol loop avoidance. Superior redundancy features include the following:
Cisco Uplink Fast and BackboneFast technologies help ensure quick failover recovery, enhancing overall network stability and reliability.
IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) provides rapid spanning-tree convergence independent of spanning-tree timers and the benefit of distributed processing.
PVRST+ allows rapid spanning-tree reconvergence on a per-VLAN spanning-tree basis, without requiring implementation of spanning-tree instances.
Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, fail-safe routing topologies.
FlexLink enables fast failover for redundant links in a Layer 2 network. FlexLink offers a faster convergence than Spanning Tree Protocol and eliminates the need for Spanning Tree Protocol.
FlexLink load balancing allows both the primary and the backup links to carry traffic for different sets of VLANs. If an interface fails, the peer interface will carry all the traffic for all VLANs.
Command-switch redundancy enabled in Cisco Network Assistant software allows designation of a backup command switch that takes over cluster-management functions if the primary command switch fails.
Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links to be detected and disabled to avoid problems such as spanning-tree loops.
Switch port autorecovery (errdisable) automatically attempts to reenable a link that is disabled because of a network error.
Cisco RPS 2300 support provides superior internal power-source redundancy, resulting in improved fault tolerance and network uptime.
Equal-cost routing (ECR) provides load balancing and redundancy.
Bandwidth aggregation of up to 8 Gbps through Cisco Gigabit EtherChannel technology and up to 800 Mbps through Cisco Fast EtherChannel technology enhances fault tolerance and offers higher-speed aggregated bandwidth between switches and to routers and individual servers.
High-Performance IP Routing
Cisco Catalyst 3750 v2 Series Switches deliver high-performance, hardware-based IP routing. The Cisco Express Forwarding CEF/dCEF) routing architecture enables outstanding scalability and performance.
Implementation of routed uplinks to the core improves network availability by enabling faster failover protection and simplifying the Spanning Tree Protocol algorithm by terminating all Spanning Tree Protocol instances at the aggregator switch. If one of the uplinks fails, quicker failover to the redundant uplink can be achieved with a scalable routing protocol such as Open Shortest Path First (OSPF) or Enhanced Interior Gateway Routing Protocol (EIGRP) rather than relying on standard Spanning Tree Protocol convergence. Redirection of a packet after a link failure using a routing protocol results in faster failover than a solution that uses Layer 2 spanning-tree enhancements. Additionally, routed uplinks allow better bandwidth use by implementing ECR on the uplinks to perform load balancing. Routed uplinks optimize the utility of uplinks out of the LAN by eliminating unnecessary broadcast data flows into the network backbone.
Other high-performance routing features include the following:
Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing.
Basic IP unicast routing protocols (static, RIPv1, RIPv2, EIGRP-Stub and OSPF) are supported for small-network routing applications.
Advanced IP unicast routing protocols (OSPF, Interior Gateway Routing Protocol [IGRP], EIGRP, and Border Gateway Protocol Version 4 [BGPv4]) are supported for load balancing and construction of scalable LANs. The IP Services license is required.
IPv6 unicast routing capability (static, RIP, OSPF, and EIGRP) forwards IPv6 traffic through configured interfaces (the IP Services license is required).
PBR allows superior control by enabling flow redirection regardless of the routing protocol configured. The IP Services license is required.
Inter-VLAN IP routing provides full Layer 3 routing between two or more VLANs.
Protocol Independent Multicast (PIM) for IP multicast routing is supported, including PIM sparse mode (PIM-SM), PIM dense mode (PIM-DM), and PIM sparse-dense mode. The IP Services license is required.
Distance Vector Multicast Routing Protocol (DVMRP) tunneling interconnects two multicast-enabled networks across nonmulticast networks. The IP Services license is required.
Fallback bridging forwards non-IP traffic between two or more VLANs. The IP Services license is required.
Integrated Cisco IOS Software Features for Bandwidth Optimization
The Cisco Catalyst 3750 v2 Series offers several advanced features for bandwidth optimization:
Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading overall system performance.
IEEE 802.1d Spanning Tree Protocol support for redundant backbone connections and loop-free networks simplifies network configuration and improves fault tolerance.
PVST+ allows for Layer 2 load sharing on redundant links to efficiently use the additional capacity inherent in a redundant design.
IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) allows a spanning-tree instance per VLAN, enabling Layer 2 load sharing on redundant links.
ECR provides load balancing and redundancy.
Virtual Route Forwarding (VRF) Lite enables a service provider to support two or more VPNs with overlapping IP addresses.
VRF-aware IP services enable the use of functions such as TFTP, FTP, syslog, SNMP, traceroute, ping, HSRP, ARP, and IP service-level agreements (SLAs) within a VRF instance.
Local Proxy ARP works in conjunction with Private VLAN Edge to reduce broadcasts and increase available bandwidth.
VLAN1 reduction allows VLAN1 to be disabled on any individual VLAN trunk link.
VLAN Trunking Protocol (VTP) pruning limits bandwidth consumption on VTP trunks by flooding broadcast traffic only on trunk links required to reach the destination devices.
IGMPv3 snooping for IPv4 and IPv6 Multicast Listener Discovery Versions 1 and 2 (MLDv1 and v2) snooping provide fast client joins and leaves of multicast streams and limit bandwidth-intensive video traffic to only the requestors.
IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port.
Multicast VLAN registration (MVR) continuously sends multicast streams in a multicast VLAN while isolating the streams from subscriber VLANs for bandwidth and security reasons.
Source-Specific Multicast (SSM) simplifies multicast deployment and optimizes bandwidth for one-to-many applications, such as a corporate video broadcast.
Multicast VRF-Lite enables multicast virtualization and separation of VRF traffic.
EIGRP stub and PIM stub enable multicast and routing on the uplinks, within the IP Base feature set.
IGMP Proxy enables the switch to process IGMP client requests, within the IP Base feature set.
Cisco IP SLAs allow you to optimize IP business applications, including VoIP, video, and data, by measuring end-to-end service levels and performance. This feature can be used to monitor performance and to prove service levels. The IP SLA requestor function requires the IP Services license, but the IP SLA responder function is available within the IP Base license.
The Cisco MAC Notification MIB enables you to monitor MAC table use and to track end-device movement across the network. This feature also allows you to set threshold limits for notification of MAC changes.
Advanced QoS
The Cisco Catalyst 3750 v2 Series offers superior multilayer, granular QoS features to help ensure that network traffic is classified and prioritized, and that congestion is avoided in the best possible manner. Configuration of QoS is greatly simplified through Auto-QoS, a feature that detects Cisco IP Phones and automatically configures the switch for the appropriate classification and egress queuing. Other QoS features include the following:
Cross-stack QoS allows QoS to be configured across the entire stack.
Standard IEEE 802.1p class-of-service (CoS) and differentiated services code point (DSCP) field classification are provided, using marking and reclassification on a per-packet basis by source and destination IP address, source and destination MAC address, or Layer 4 TCP or User Datagram Protocol (UDP) port number.
Cisco control- and data-plane QoS ACLs on all ports help ensure proper marking on a per-packet basis.
Four egress queues per port enable differentiated management of up to four traffic types.
Shaped Round Robin (SRR) scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress and egress queues.
Weighted Tail Drop (WTD) provides congestion avoidance at the ingress and egress queues before a disruption occurs.
Strict priority queuing helps ensure that the highest-priority packets are serviced ahead of all other traffic.
There is no performance penalty for highly granular QoS functions.
IP SLAs allow you to optimize IP business applications for VoIP, video, and data by measuring end-to-end service-level and performance metrics.
The Cisco Committed Information Rate (CIR) function helps ensure bandwidth in increments as low as 8 Kbps.
Rate limiting is provided based on source and destination IP address, source and destination MAC address, Layer 4 TCP and UDP information, or any combination of these fields, using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy maps.
Asynchronous data flows upstream and downstream from the end station or on the uplink are easily managed using ingress policing and egress shaping.
Up to 64 aggregate or individual policers are available per Fast Ethernet or Gigabit Ethernet port.
Intelligent PoE Management
The Cisco Catalyst 3750 v2 Series PoE models support Cisco IP Phones and Cisco Aironet WLAN access points as well as any IEEE 802.3af-compliant end device. These are some of the advanced PoE features available:
Cisco Discovery Protocol Version 2 allows the Cisco Catalyst 3750 v2 Series Switch to negotiate a more granular power setting when connecting to a Cisco powered device, such as an IP phone or access point, than what is provided by IEEE classification.
The Per-port power consumption command allows customer to specify the maximum power setting on an individual port.
Per-port PoE power sensing measures the actual power being drawn, enabling more intelligent control of powered devices.
The PoE MIB provides proactive visibility into power use and enables power policing and troubleshooting.
Link Layer Discovery Protocol (LLDP) and LLDP for Media Endpoint Devices (LLDP-MED) add support for the IEEE 802.1AB LLDP for interoperability in multivendor networks. Switches exchange speed, duplex, and power settings with end devices such as IP phones.
Management and Control Functions
A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS Software revision running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.
The Cisco Catalyst 3750 v2 Series stacks up to nine switches as a single logical unit, for a total of 468 Ethernet or PoE 10/100 ports. Additional port combinations can be created by connecting the Cisco Catalyst 3750 and 3750-E Series Switches to the stack. Individual 10/100, 10/100/1000, and 10 Gigabit Ethernet units can be joined in any combination to evolve with network needs.
In addition, the Cisco Catalyst 3750 v2 Series Switches come with an extensive set of management and control features:
Cisco IOS Software CLI support provides a common user interface and command set with all Cisco routers and Cisco Catalyst desktop switches.
Cisco Discovery Protocol Version 2 allows the Cisco Catalyst 3750 v2 Series Switch to negotiate a more granular power setting when connecting to a Cisco powered device, such as an IP phone or access point, than what is provided by IEEE classification.
The PoE MIB provides proactive visibility into power use and allows customers to set different power-level thresholds.
Switching Database Manager templates for access, routing, and VLAN deployment scenarios allow the administrator to easily increase the memory allocation to the desired features based on deployment-specific requirements.
Cisco Generic On-Line Diagnostics (GOLD) checks the health of hardware components and verifies proper operation of the system data and control planes at run time and boot time.
VLAN trunks can be created from any port, using either standards-based IEEE 802.1Q tagging or the Cisco Inter-Switch Link (ISL) VLAN architecture.
Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier administration and troubleshooting.
Cisco VTP supports dynamic VLANs and dynamic trunk configuration across all switches.
Cisco Group Management Protocol server functions help enable a switch to serve as the Cisco Group Management Protocol router for client switches. The IP Services license is required.
IGMPv3 snooping provides fast client joins and leaves of multicast streams and limits bandwidth-intensive video traffic to only the requestors.
Remote SPAN (RSPAN) allows administrators to remotely monitor ports in a Layer 2 switch network from any other switch in the same network.
For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events).
Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source to destination.
All nine RMON groups are supported through a SPAN port, which permits traffic monitoring of a single port or a group of ports from a single network analyzer or RMON probe.
Domain Name System (DNS) provides IP address resolution with user-defined device names.
TFTP reduces the cost of administering software upgrades by downloading from a centralized location.
Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches.
Multifunction LEDs per port for port status; half-duplex and full-duplex mode; and 10BASE-T, 100BASE-TX, and 1000BASE-T indication as well as switch-level status LEDs for system, redundant power supply, and bandwidth use provide a comprehensive and convenient visual management system.
LLDP location support enables location-based services, such as end-device location, emergency responder, location-based QoS, location-based VLAN assignment, and location-based power management.
Cisco Network Assistant
Cisco Network Assistant is a PC-based network-management application with a user-friendly GUI. Available at no cost, Cisco Network Assistant can be downloaded from Cisco.com.

Power Connectors
|
Customers can provide power to a switch by using either the internal power supply or the Cisco RPS 2300. The connectors are located at the back of the switch.
Internal power supply connector
The internal power supply is an autoranging unit.
The internal power supply supports input voltages between 100 and 240 VAC.
Use the supplied AC power cord to connect the AC power connector to an AC power outlet.
Cisco RPS connector
The connector offers connection for an optional Cisco RPS 2300 (model PWR-RPS2300) that uses AC input and supplies DC output to the switch.
