6500 IOS HSRP Gateway not responding to ARP requests

Level 1

WS-C6509, running Native IOS version 12.2(33)SXH4. Pair of 6500 configured with HSRP serving as Gateway to down stream clients

Ping requests from clients not having a Default Gateway (AIX Server Team recommendation) failing.

Packet capture show ARP requests being received by Gateway 6500, but Gateway will not respond for up to 30 seconds at which point ping requests will start working. But after a period of inactivity, the cycle starts over again - 30 second delay before traffic starts flowing.

Having a Default Gateway is a separate discussion. I'm just interested in being able to provide technical reason why this is occuring.

Anyone experience this?

Any suggestions for addtional troubleshooting measures?

Thanks in advance.

Looks to me like a timer problem - maybe a ARP timer on the clients? Check the ARP tables of your clients during your tests.
