The Cisco Enhanced EtherSwitch Service Module helps ensure maximum availability, high performance, ease of upgrade, and expandability. The modules have their own processors, switching engines, and flash memory that run independently of host router resources, helping ensure maximum concurrent switching and routing performance as well as providing integrated PoE, security, and increased ease of management. Additionally, Cisco Enhanced EtherSwitch Service Modules run their own Cisco IOS ® Software, independent of the router Cisco IOS Software image, allowing for easy upgrades and ongoing software and feature commonality with Cisco Catalyst 2960 and Catalyst 3560-E Series Switches. Table 2 lists some of the features and benefits of this architecture.
