<DIV><SPAN class=451585220-16022007><FONT face=Arial size=2>I have a foundry

<DIV><SPAN class=451585220-16022007><FONT face=Arial size=2>I noticed today that
40% of my CPU is being used by the ARP Input process on my
Catalyst.</FONT></SPAN></DIV>

<DIV><SPAN class=451585220-16022007><FONT face=Arial size=2>I also noticed by
using debug arp on the cisco that pretty much all of the arp traffic is coming
from the ServerIron.</FONT></SPAN></DIV>

<DIV><SPAN class=451585220-16022007><FONT face=Arial size=2>The catalyst has a
vlan, and the serveriron is part of that vlan. The server iron uses the catalyst
as its default gateway.</FONT></SPAN></DIV>

<DIV><SPAN class=451585220-16022007><FONT face=Arial size=2>There are hosts
connected to the ServerIron which use the server iron for its
gateway.</FONT></SPAN></DIV>

<DIV><SPAN class=451585220-16022007><FONT face=Arial size=2>For some reason it
looks like for every destination the serveriron is sending an arp request to the
Catalyst instead of trying to route it.</FONT></SPAN></DIV>
