Hi,
is there a way to clear one arp-cache entry in the 6509s. I have a mac that has two IPs associated with it. I could clear the arp-cache of the whole vlan? Would this disrupt any users on this vlan? Also, any explanation of why this would happen? The user was recently moved from vlan 2 to 29. Thanks
Internet 170.117.57.210 1 0011.2567.d84d ARPA Vlan2
Internet 10.10.28.119 58 0011.2567.d84d ARPA Vlan29
I would have to wait three more hours for it to clear.

You could try it like this:
The following example shows how to refresh dynamically learned ARP cache entries for the host at 192.0.2.140:
Router# clear arp-cache 192.0.2.140

Yeah, there is still a lot of difference between the router images and those for switches.
That's why I said "you can try".
This was a command introduced in 12.0 so if possible, it would have been in there.
Nevermind. Only two hours to go before the problem resolves itself!

Thanks Leo. It was actually a dns issue. My Sys admin schooled me on it.

Hi,
What i know abt Dns is, it resoves ip to hostname vice versa;
so how it is affected in ur case.
