VLAN ISL Trunking

2000-07-20 Thread Luong, David
Hi Group: Given 2900 series variations of switches and the capability of enabling "multi-VLAN" (ie. assigning more than 1 vlan on each port), what are the advantages of using ISL-aware NICS instead? One scenario I'm thinking is having a server port on switch configure for 2 vlans (vlan 2 + vlan3)

I would think the difference is multi-vlan port can't block inter-vlan multicast and broadcast, for example, it will forward unknown mac frame or multiple vlans stp message to all vlans to which it was assigned, but ISL trunking will restrict MC and BC in it's original vlan, which is good. :) Hop
