When is ARP cache entry is changed from reachable to stale exactly???
I want to know when ARP cache entry become STALE from reachable state.
In my system am using eth0 adapter and this interface settings are as follows.
By having above settings i have observed the following.
Entry in ARP cache table becomes stale from reachable differently from time to time.
once it becomes for 60 sec,some other time it is 64 sec,some other time 50 sec and so on.
Why is it happening??
Any help would be appriciated highly.
