•Cisco IOS Release 12.3 or later release
Prerequisites for the Cisco EtherSwitch Network Module
•Basic configuration of the Cisco 2600 series, Cisco 3600 series, or Cisco 3700 series router
In addition, complete the following tasks before configuring this feature:
•Configure IP routing
For more information on IP routing, refer to the Cisco IOS IP Configuration Guide
•Set up the call agents
For more information on setting up call agents, refer to the documentation that accompanies the call agents used in your network configuration.

Cisco EtherSwitch Network Module: Benefits
•Statistical gains by combining multiple traffic types over a common IP infrastructure.
•Long distance savings
•Support for intra-chassis stacking
•Voice connectivity over data applications
•IPSec, ACL, VPN and Firewall options
•New broadband WAN options
The Interface Range Specification feature makes configuration easier for these reasons:
•Identical commands can be entered once for a range of interfaces, rather than being entered separately for each interface.
•Interface ranges can be saved as macros.
