Is "ip gratuitous-arps" enabled on the switches/routers by default? (specifically Cat 6500's)
We're moving some SVI's from a switch to another one.
Since the servers will have the old ARP/MAC cached in their arp table, we'd like to figure out a way to make the servers learn the new ARP/MAC entry for their default gateway w/o manually clearing arp cache on each server.
Would the switches send gratuitous-arps out to inform the servers of the move of the new SVI's?
I found another thread about gratuitous-arp, but it has no mention of what I'm looking for:
I think if you enable ip gratitious-arp on the svi on the new switch, it will send the that arp packet to the connected hosts to update their Cache Entry for that IP address - basic gratitious arp defination. But if i was you , i would still test it in a test set up before making changes in the production network.
