hello group,

cco says
"To reduce the risk of spanning-tree loops or storms, you can disable VLAN 1
on any individual VLAN trunk port by removing VLAN 1 from the allowed list.
This is known as VLAN 1 minimization. VLAN 1 minimization disables VLAN 1 (the
default VLAN on all Cisco switch trunk ports) on an individual VLAN trunk
link. As a result, no user traffic, including spanning-tree advertisements, is
sent or received on VLAN 1. "
isnt that statement somewhat contradictory by itself...
it says "To reduce the risk of spanning-tree loops or storms"
then it says no user traffic, including spanning-tree advertisements, is sent
or received on VLAN 1.
afaik, blocking spanning tree advertisement is "a reason" for spt loops.
i would be happy if someone can shed some light on this one.

Ozgur
