Overview
Cisco
Catalyst 6500 Series Switches offer a variety of Ethernet modules to serve
different needs in the campus and data center for enterprise, commercial, and
service provider customers. The Cisco Catalyst 6904 4-Port 40 Gigabit Ethernet
Fiber Module (Figure 1), fully compliant with the IEEE 802.3ba standard,
complements this product portfolio.
The
module is designed to meet the increasing demand for aggregation of 10 Gigabit
Ethernet on campus and data center, as well as for high-density 10 Gigabit
Ethernet and 40 Gigabit Ethernet transport in the core.
Each
port can accept a 40 Gigabit Ethernet C Form-Factor Pluggable (CFP) optics
module or be converted to four ports of 10 Gigabit Ethernet with a FourX
adapter, enabling customers to deploy 10 Gigabit Ethernet to meet current needs
and be ready to transition to 40 Gigabit Ethernet without any disruption. The
module can also be used in mixed mode, where one side of the card uses two CFP
modules for 2 times 40 Gigabit Ethernet ports and the other side uses two FourX
adapters for 8 times 10 Gigabit Ethernet ports.
The
Cisco Catalyst 6900 Series 4-Port 40 Gigabit Ethernet Fiber Module is compatible
only with Cisco Catalyst 6500 Supervisor Engine 2T.
Cisco
Catalyst 6900 Series 4-port 40 Gigabit Ethernet Fiber Module can operate in a
number of modes. Performance mode enables 80 Gigabit Ethernet performance by
using two ports without oversubscription. In Oversubscribed mode, the module
uses four ports with 2:1 oversubscription. Details are as
follows:
40
Gigabit Ethernet Oversubscribed mode (default)
Four
40 Gigabit Ethernet ports using CFP transceivers.
Ports
are numbered as interface FortyGigabitEthernetslot#/1-4 (Figure
1).
The
interface range command is allowed.
10
Gigabit Ethernet Oversubscribed mode
16
10 Gigabit Ethernet ports using FourX adapters.
Each
FourX adapter has 4 SFP+ transceivers.
Ports
will be numbered as interface TenGigabitEthernetslot#/5-20 (Figure
2).
The
interface range command is allowed.
Mixed
10/40 Gigabit Ethernet mode
One-half
of the module uses two CFP transceivers for 2 x 40 Gigabit Ethernet ports, while
the other half uses two FourX adapters for 8 x 10 Gigabit Ethernet
ports.
Depending
on which side has the 40 Gigabit Ethernet ports, port numbering is as
follows:
40
Gigabit Ethernet ports on left: Interface FortyGigabitEthernet slot#/1-2 and
interface
TenGigabitEthernetslot#/13-20.
40
Gigabit Ethernet ports on right: InterfaceTenGigabitEthernetslot#/5-12 and
interface
FortyGigabitEthernetslot#/3-4.
Performance
mode (Figure 3)
Note
that Oversubscribed mode is the default setting.
In
40 Gigabit Ethernet Performance mode, ports 1 and 3 will be
active.
In
10 Gigabit Ethernet Performance mode, ports 5-8 and 13-16 will be
active.
The
command-line interface (CLI) is required to change modes. Check release notes
for details.
The
mode can be changed per port group.
The
4-Port 40 Gigabit Ethernet Fiber Module provides up to 44 x 40 Gigabit Ethernet
Fiber ports in a single Cisco Catalyst 6513-E chassis and 88 x 40 Gigabit
Ethernet ports in a Cisco Catalyst 6500 Virtual Switching System (VSS) 4T. The
module has two 40-Gbps connections (for a total of 80 Gbps) to the 2-Tbps switch
fabric of the Cisco Catalyst Supervisor Engine 2T, providing 2:1
oversubscription when all four ports of 40 Gigabit Ethernet or 16 ports of 10
Gigabit Ethernet ports are active.
Cisco
Catalyst 6904 modules support two types of CFP optics: CFP-40G-LR4 and
CFP-40G-SR4, providing operational distances of up to 10-km over single-mode
fiber and 100m over OM3 multimode fiber, respectively. FourX adapters support a
variety of Small Form-Factor Pluggable Plus (SFP+) optics, as listed in Table
2.
Each
of the 40/10 Gigabit Ethernet ports supports Cisco TrustSec
technology and IEEE 802.1ae (MACsec) encryption. The 40/10 Gigabit Ethernet
ports also support Security Group Access Control Lists (SGACL), also known as
Role-Based Access Control Lists (RBACL), and both Layer 2 and Layer 3 Security
Group Tagging (SGT) functionality. The module also supports Virtual Switch Link
(VSL) on all ports in both Oversubscribed mode and Performance
mode.
