Just wondering why, when i do show arp, in my WS-C4506, whith Supervisor II+ 1000BaseX, and cat4000-i9k91s-mz.122-25.EWA5.bin, it seems that i have +/- 20 % of arp entrys with the aging time of 0 sec all the time.
I think it should increment that aging time till 300 sec (by default), and then reset, but not all the entries do it.
Any ideias of what kind of "process" is causing it ?
I have all in the vlan1, and the ip's that soffer this issue are hosts and Cisco equipments.
Thank you in advance.
