This is a AAA command that is not directly related to the 3550.
The "ip radius source-interface" and "ip tacacs source-interface"
commands tell the network client what source address to use for
radius/tacacs packets sent to the AAA server. Normally the traffic is
sourced from the IP address of the outgoing interface in the routing
table. However when you authenticate to AAA the server typically will
have the network clients' IP addresses that are allowed to authenticate
statically configured. So if you have 10 VLAN interfaces on the switch
you may not want 10 entries in the AAA server that all point to the same
device. Instead you could say "ip radius source-interface Vlan 10" and
the packets will always come from that IP address.
