Re: spanning-tree

[Karen . Young]

Elmer,

Spanning tree uses the _lowest_ value, not the highest. By raising the
value, you're guaranteeing that traffic will go opposite of what you want.
Also, you need to lower the bridge priority, not the port priority or port
cost..

The default value is 32K (32768). Just change this to 16K or 8K on the
switch you want to be the root. The command is:

     set spantree priority <value> <vlan>

the <vlan> is optional and only gets used if you are setting up different
instances of spanning tree per VLAN (a good way to do some load sharing).

As an alternative, you could use this command:

     set spantree root

The only problem with using this one is that you have less control over the
results. Its kind of a brute force method.

Hope this helps.

Hi, all. I 've tried increasing the port cost to have spanning-tree go in
one direction, like SwitchA would be forwarding and SwitchB would be
blocking.


But it still ends up with SwitchB as the forwarding switch. Am i to
configure
another entry somewhere? Thanks in advance.
