If one of the 2 ports of the switch where you are connected is badly configured (wrong VLAN, ...), you may have problems. The link can be up but being unusable. In that case, having something like the arp monitor seems to not be so stupid; doesn't it ? -- Olivier Cherrier - Symacx.com mailto:[email protected]
