spanning tree

Hi all, can anyone clarify this for me, If I have say 2 vlans on my network, can spanning tree be forwarding on an uplink port say for vlan 2, and be blocking for vlan 3 ? and would the port light be showing as orange, or as green as its forwarding for one of the vlans ?

Re: spanning tree

Yes you are right you can do this with spanning tree. This is basicly load balancing. check this out:

Orange and Green mean the line is 10Mb or 100 Mb...

Pls rate if it helps

Re: spanning tree

how is this load balancing ? does spanning tree do blocking for one vlan and forwarding for one vlan by default ?

Re: spanning tree

By default Spanning tree block one port and put other port in forwarding for all VLAN.

All it depends how did you configure your root bridge for that particular VLAN. If you have different root bridge for different VLAN then particular port can be in forwarding for one vlan and blocking for other.
