Included with the Cisco Catalyst 3550-24, 3550-24-DC, 3550-24-FX and 3550-48 are the Standard Multilayer
Software Image (SMI) or the Enhanced Multilayer Software Image (EMI). The SMI feature set includes advanced
QoS, rate-limiting, access control lists (ACLs), and basic state and RIP routing functionality. The EMI provides a
richer set of features including advanced hardware-based IP unicast and multicast routing and the Web Cache
Communication Protocol (WCCP). After initial deployment, the Enhanced Multilayer Software Image Upgrade Kit
gives users the flexibility to upgrade to the EMI. The Cisco Catalyst 3550-12T and 3550-12G are only available with
the EMI.
