Hi group,
I have 2 3550's connected through ports 9 & 10.I have
some vlan's say 2,3,4,5 but don't have any of my ports in vlan 1.If it is
asked to pass vlan's 2 & 3 through port 9 and the 4 & 5 through port 10, and
only these configured vlan's alone should be trunked, Which of these solutiond
should I apply ?
1. Configure the required vlan's on port 9 & 10 using
"switchport trunk allowed vlan 2,3" on port 9 and "switchport trunk allowed
vlan 4,5 " on port 10 of both swithces.
2. Need I consider redundancy here by
manipulating Spanning-tree parameters ( port-priority or cost) .ie Suppose
Sw1 is the root bridge.By default port 10 will be in blocking state.So I can
configure "spanning-tree port-priority vlan 4,5 64 " on port 10 of Switch1.And
configure "switchport trunk allowed vlan 2,3,4,5 " on both ports of both
Switches.
Which of these is more correct ?
My another question is Need I
explicilty allow vlan 1 along with vlan's 1002-1005 ? Will spanning-tree &
CDP function properly without vlan 1 ?
Thanks,
Peter
