I've introduced dynamic arp inspection in accordance with arp access-list (s) and experienced the following trouble:
The inspection sometimes (three times a week) fails. Well formed arp responses are denied. The workaround is to load the same access-list again.
I have two similarly configured nets. The first has a C3560G in core, the second two C3750G in stack. Failures occurs only on the slave in stack.
IOS is Version 12.2(25)SEE2 in both cases.
Is it something known about this issue, or seems to be rather a HW failure on the slave?
