Q. What are the Cisco ® Enhanced EtherSwitch ® Service Modules?
A. These integrated switching modules for the Cisco integrated services routers expand router capabilities by integrating Layer 2 and Layer 3 switching with feature sets identical to those found in Cisco Catalyst ® 3560-E and Catalyst 2960 Switches. The new modules also provide a 1-Gbps connection to the multigigabit fabric (MGF) for intermodule communication that does not burden the router CPU.
Q. What are the benefits of using the Cisco Enhanced EtherSwitch Service Modules?
A. Integrated switching and routing provides:

Lower cost of ownership: It allows network administrators to manage a single device using the router command-line interface (CLI) or Cisco management tools for LAN and WAN management needs.

Lower mean time to repair (MTTR): One vendor means one support center to decrease troubleshooting time and eliminate blaming among vendors.

Software parity: Cisco Catalyst 2960 and Catalyst 3560-E software parity enables IT to certify and deploy the same services at the main and branch offices.

Single maintenance contract: A Cisco SMARTnet® contract covers both the router and the Cisco EtherSwitch module.

Feature, schedule, and roadmap alignment: The features, schedule, and roadmap of the Cisco Enhanced EtherSwitch Service Module and Cisco Catalyst 2960 and Catalyst 3560-E Switches are aligned to provide a consistent user experience and to help ensure that no new hardware is required to support the latest innovations.

Easy upgrades: Cisco Enhanced EtherSwitch Service Modules run their own Cisco IOS® Software image and can be upgraded independently of the Cisco IOS Software release on the host router.

Fewer components: Fewer power supplies, fans, etc. results in fewer failures and less downtime.

Mean time before failure (MTBF): The MTBF is at least double that of a standalone switch.

Q. What platforms support the Cisco Enhanced EtherSwitch Service Module, and how many service modules can I install in each platform?
A. Table 1 lists the platforms that support the new service module and the maximum number of modules you can install in each platform.
