SMI vs. EMI

matt_heff · ‎03-11-2007

Where can I find information on the differences in features between SMI and EMI for 3550s and 3750s. I'm mainly concerned with the supported routing protocols on each and if NAT is available on both, but a list summarizing everything would be nice.

Thanks!

First, the latest releases of switch software have adopted a new naming convention:

ipbase (Formerly SMI): Cisco IOS IP base image and device manager files. This image has Layer 2+ and basic Layer 3 routing (Static, RIP) features.

ipservices(Formerly EMI): Cisco IOS IP services image and device manager files. This image has Layer 2+ and full Layer 3 features.

ipbasek9: Cisco IOS IP base cryptographic image and device manager files. This image has the Kerberos, Secure Shell (SSH), Layer 2+, and basic Layer 3 routing features.

ipservicesk9: Cisco IOS IP services cryptographic image and device manager files. This image has the Kerberos, SSH, Layer 2+, and full Layer 3 features.

The 3560/3570 switches also have an advipservices image that supports a subset of IPv6.
