ARP Cache problem. Replacing an old catalyst.
Posted on 2005-04-09
I’ve got two Catalyst switches, I am changing one switch out soon and need to clear the arp cache on the other remote Catalyst; there is no other route/link to the remote catalyst. Unfortunately I can't send a tech or drive to this remote location in a reasonable amount of time.
If I run 'clear arp' and then immediately unplug the fiber link from the local switch would the remote catalyst already have the old arp entry?
Could I reboot the remote catalyst right before I install the core switch... would this clear the arp cache?
How can I change the arp aging time in a catalyst 5000, If I could temporarily set the time-out on arp caching for say 5 mins, then I could sync the two catalysts after the time-out occurs, I think the default time out is 4 hours!?!
Anyone, Any ideas... Please help.
