The switch is getting this message " %ARP-E-ARPTBL: ARP Table Overflow" recorded in the logs every 30 seconds or so for the last day or so. Clearing the arp-cache gets rid of the message for a few minutes until it starts up again. I changed the arp timeout to 3600 from the default 60000 but no change.
The switch is running:
SW version 2.0.0.46 ( date 14-Apr-2011 time 13:10:53 )
Boot version 2.0.0.0 ( date 12-Nov-2008 time 12:56:52 )
HW version 00.00.02
This switch is lagged to the main core 6248 (the default gateway for our internal network). The switch is also connected to our firewalls (setup in active/passive mode and is the gateway to all non-internal networks) and to a cisco 2951 which handles traffic to a sister company in another city over a MPLS circuit. There are separate vlans so that traffic from the cisco must go to the firewalls and then to the LAG to main core and visa versa.
How can I prevent these messages from appearing? Or is this nothing to worry about?
Configs can be provided.
Thanks.
