The Cisco EtherSwitch service modules (NME-16ES-1G, NME-16ES-1G-P, NME-X-23ES-1G,
NME-X-23ES-1G-P, NME-XD-48ES-2S-P, and NME-XD-24ES-1S-P) provide Cisco modular access
routers the ability to stack Cisco EtherSwitch service modules as Layer 2 switches using Cisco
StackWise technology. The Cisco EtherSwitch service modules are supported by either the IP base image
(formerly known as standard multilayer image [SMI]) or the IP services image (formerly known as the
enhanced multilayer image [EMI]). The IP base image provides Layer 2+ features, including access
control lists (ACLs), quality of service (QoS), static routing, and the Routing Information Protocol
(RIP). The IP services image provides a richer set of enterprise-class features, including Layer 2+
features and full Layer 3 routing (IP unicast routing, IP multicast routing, and fallback bridging). To
distinguish it from the Layer 2+ static routing and RIP, the IP services image includes protocols such as
the Enhanced Interior Gateway Routing Protocol (EIGRP) and the Open Shortest Path First (OSPF)
Protocol.
