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          1   0011.2567.d84d  ARPA   Vlan2

Internet           58   0011.2567.d84d  ARPA   Vlan29

I would have to wait three more hours for it to clear.

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.
