Configuring Spanning Tree Protocol (STP) and Advanced STP Features
Table 8.4: CLI Display of STP Information
Displays...
The port-based VLAN that contains this spanning tree (instance of
STP). VLAN 1 is the default VLAN. If you have not configured port-
based VLANs on this device, all STP information is for VLAN 1.
The ID assigned by STP to the root bridge for this spanning tree.
The cumulative cost from this bridge to the root bridge. If this device
is the root bridge, then the root cost is 0.
The port on this device that connects to the root bridge. If this device
is the root bridge, then the value is "Root" instead of a port number.
This device or VLAN's STP priority. The value is shown in
hexadecimal format.
Note: If you configure this value, specify it in decimal format. See
"Changing STP Bridge Parameters" on page 8-4.
The number of seconds this device or VLAN waits for a hello message
from the root bridge before deciding the root has become unavailable
and performing a reconvergence.
The interval between each configuration BPDU sent by the root
bridge.
The minimum number of seconds that must elapse between
transmissions of consecutive Configuration BPDUs on a port.
The number of seconds this device or VLAN waits following a
topology change and consequent reconvergence.
The number of seconds since the last time a topology change
occurred.
The number of times the topology has changed since this device was
reloaded.
The STP address of this device or VLAN.
Note: If this address is the same as the Root ID, then this device or
VLAN is the root bridge for its spanning tree.
The port number.
The port's STP priority, in hexadecimal format.
Note: If you configure this value, specify it in decimal format. See
"Changing STP Port Parameters" on page 8-6.
The port's STP path cost.
