Q.
What is the difference between the EMI and the SMI?
A.
The Cisco Catalyst 3550-24, Catalyst 3550-48, and Catalyst 3550-24 PWR switches can be ordered with the SMI or the
EMI. The Cisco Catalyst 3550-24 DC and Catalyst 3550-24 FX can only be ordered with the SMI preinstalled, but as with
all switches running the SMI, they can be upgraded to the EMI version using an EMI upgrade kit. The Cisco Catalyst
3550-12T and Catalyst 3550-12G switches come installed with EMI. The EMI enables a richer set of enterprise-class
features including advanced hardware-based IP unicast and multicast routing, Policy-Based Routing (PBR), and the Web
Cache Communication Protocol (WCCP). Additional details about the differences between the SMI and EMI are provided
later in this Q&A.
