To display detailed information about 802-1W, using the following command:
Syntax:
show 802-1w detail [vlan <vlan-id>]
The
vlan
<vlan-id> parameter displays 802.1W information for the specified port-based VLAN.
The
show spanning-tree 802.1W
command shows the following information.
State
The port’s current 802.1W state. A port can have one of the following
states:
•
Forwarding
•
Discarding
•
Learning
•
Disabled
Refer to “Bridge Port States” on page 7-22 and “Edge Port and Non-
Edge Port States” on page 7-22.
Designated Cost
The best root path cost that this port received, including the best root
path cost that it can transmit.
Designated Bridge
The ID of the bridge that sent the best RST BPDU that was received
on this port.
This Field...
