PIX 525 arp issue

Hi,

I've been experiencing problem with my standby pix. My outside interface becomes unavailabl after 4 hours (arp cache. I have to clear my arp table for me to access it again.

My pix is connected to a switch. 2 routers with HSRP config and the primary pix is also connected via this switch.

from the table it seems that the arp table of the standby doesnt get refresh.

Also, i am receiving these logs

405001: Received ARP response collision from x.x.x.x/0000.0c07.xxxx on interface outside

405001: Received ARP response collision from x.x.x.x/0000.0c07.xxxx on interface outside

405001: Received ARP response collision from x.x.x.x/000d.xxxx.xxxx on interface outside

is this the cause why the arp table counter doesnt have a value? whats the work around for this? hope someone could help.

Thanks

Re: PIX 525 arp issue

static arp binding can resolve your issue
