The Cisco SM-X Layer2 EtherSwitch Service Module is crafted to reduce your company's total cost of ownership (TCO) by integrating Gigabit Ethernet (GE) ports within the Cisco ISR4000 Series routers. Extending the power of intent-based networking, this integration allows network administrators to configure a single box for all LAN and WAN needs lowering network complexity and maintenance.

The Cisco SM-X EtherSwitch Modules provides for an enterprise class line of features on the Cisco ISR 4000 series routers, greatly expanding the capabilities of the router by integrating industry-leading Layer 2 switching with feature sets that are built on the lines of those found in the Cisco Catalyst 9200 Series switches.

The Cisco SM-X Layer2 EtherSwitch Service Module takes advantage of the increased capabilities on the Cisco UADP module to provide scale, security and ease of operation. Because the Cisco SM-X Layer2 EtherSwitch Service Modules support the same UADP 1.0 ASIC as the Catalyst 9200 it allows the module to provide a ubiquitous configuration at headquarters and at the branch office to create a consistent experience throughout your network.

Supported models and configurations
Table 1 gives specifications of the Cisco SM-X EtherSwitch Service Modules. All Gigabit Ethernet ports support auto-negotiating 10/100/1000 Mbps. Based on the model up to 8-ports of 2.5G mGig support helps provide uplink connectivity to Access Points and Uplink Expansions, external Advanced 4G LTE and (future) 5G connections. Up to two 10G SFP+ based fiber ports provide for Server connectivity or for high speed aggregated connection to high-speed switches.
