RE: Local Proxy ARP

Protected mode is a form a private vlan on a 3550.

I die. I fracture into thousands of fragments of flushed embarrassment.
My body parts fly, connectionless, over a badly constructed spanning
tree that isn't quite loop free.
I fall screaming into 127.0.0.1.

I guess I'm not familiar with "protected mode" on switch ports...does
this have to do with 802.1X?

Local proxy arp feature responds to arp requests of *local* IP
addresses.
Example:
HostA and HostB are in the same VLAN, their ports are set to protected
mode. They won't be able to communicate with each other directly since
ARP won't go through. To enable them to communicate through the router
local proxy arp feature could be enabled on the appropriate interface of
the router.
