I have a 2801 router with a 4 port POE switch card. I have a PC plugged into one of the switch ports.
For some reason every 1 or 2 min I stop seeing the MAC in the mac-address-table (it is still in the arp cache though).
If I start pinging it again I lose the first 15-20 pings and then I can ping it again (the mac-address-table get populated again witgh the right info). After 1-2 minutes I lose it again...
any ideas ?
(I have increased the aging time with no luck)
