Global STP parameters
VLAN ID 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.
Root ID The ID assigned by STP to the root bridge for this spanning tree.
Root Cost The cumulative cost from this bridge to the root bridge. If this device is the root
bridge, then the root cost is 0.
Root Port 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.
Priority Hex This device or VLAN STP priority. The value is shown in hexadecimal format.
NOTE: If you configure this value, specify it in decimal format. Refer to “Changing
STP bridge parameters” on page 211.
Max age sec The number of seconds this device or VLAN waits for a configuration BPDU from
the root bridge before deciding the root has become unavailable and performing a
reconvergence.
Hello sec The interval between each configuration BPDU sent by the root bridge.
Hold sec The minimum number of seconds that must elapse between transmissions of
consecutive Configuration BPDUs on a port.
Fwd dly sec The number of seconds this device or VLAN waits following a topology change and
consequent reconvergence.
Last Chang sec The number of seconds since the last time a topology change occurred.
Chg cnt The number of times the topology has changed since this device was reloaded.
Bridge Address 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.
Port STP parameters
Port Num The port number.
Priority Hex The port STP priority, in hexadecimal format.
NOTE: If you configure this value, specify it in decimal format. Refer to “Changing
STP port parameters” on page 212.
Path Cost The port STP path cost.
