Cisco 6500 Core Switches and Clear arp-cache

We have two 6500 series core switches on our network and after we do a
clear-arp-cache it takes about 7 hours unit our internal computers on
the network can browse the internet with on port 80 with arp. HTTPS
web sites are not affected. Does anyone have any ideas on what might
be causing this? thank you

 

Clearing the arp cache should not affect http port 80 sites any differently
than https on port 443. Also note that arp is only significant local
interfaces, it does not survive the first layer 3 hop. I would plug a
sniffer in and take a look. This doesn't make much sense. Are you using a
proxy?

 

What OS the cats are running? Hybrid/native?

I agree clear arp cache should not affect any? So when you do have
problems after clear arp.., were your clients able to ping the
inetrnet addresses? if you are using a proxy server.., you may want to
start your troubleshooting from there.

Give us more info..

 

Yes we are running to squid proxy servers and in the past I have
questioned this as the problem however I am told by the managing group
of those boxes that this is not the problem but a problem with the
transparent proxy.
