Cisco Enhanced EtherSwitch Service Module
Q.
What are the Cisco
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
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
●
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.

- Page 1 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 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.
- Page 2 The ES3 performs Layer 2/3 switching in hardware and offers full feature parity with the Cisco Catalyst 3560-E IP Base and IP Services universal feature sets. The ES2 service module is based on the Cisco Catalyst 2960 Series desktop switches; it performs Layer 2 switching in hardware and offers full feature parity with the Cisco Catalyst 2960 LAN Base image.
- Page 3 Should I expect the current Cisco EtherSwitch Network Modules to reach end-of-sale status soon? No plan for end of sale of either of these cards currently exists. The existing Cisco EtherSwitch Network Modules provide a switching option to the installed base of Cisco 2811, 2821, 2851, 3825, and 3845 Integrated Services Routers.
- Page 4 Is online insertion and removal (OIR) supported? Yes, but first you must stop the Cisco Enhanced EtherSwitch module with the hw-module sm X oir-stop CLI command. After you insert the new module, then issue the hw-module sm X oir-start CLI command. The part numbers of the replacement module and the one removed must be the same.
- Page 5 Where do I download the software for the ES2 and ES3 versions? The software will be downloaded from the Cisco website in a section under the ISR 2900/3900. Note: unlike some earlier versions of EtherSwitches, it will not be downloaded from the switch portal. The software is located on the same CCO landing page as Cisco 2911, 2921, 2951, 3924, 3945 routers.
- Page 6 The IEEE 802.3af PoE supports up to 15.4 watts per port and Cisco ePoE supports up to 20 watts per port. The amount of power available to the enhanced Ethernet ports is limited by the power-supply capabilities of the hosting platform.
- Page 7 Can I use the Cisco Configuration Engine to deploy the router and Cisco Enhanced EtherSwitch Service Modules? Yes, Cisco IE 2100 Series agents are embedded in Cisco IOS Software; they run on both Cisco integrated services routers and Cisco Enhanced EtherSwitch Service Modules.
