IEEE 802.1D Spanning Tree Protocol (STP)
12
Bridge MaxAge sec The number of seconds this bridge waits for a hello message from the root
bridge before deciding the root has become unavailable and performing a
reconvergence.
Bridge Hello sec The interval between each configuration BPDU sent by the bridge.
Bridge FwdDly sec The number of seconds this bridge waits following a topology change and
consequent reconvergence.
Hold Time sec The minimum number of seconds that must elapse between transmissions of
consecutive Configuration BPDUs on a port.
Last Topology Change sec The number of seconds since the last time a topology change occurred.
Topology Change cnt The number of times the topology has changed since this device was reloaded.
Root Bridge Parameters
Root Identifier The ID assigned by STP to the root bridge for this spanning tree in hexadecimal.
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.
DesignatedBridge Identifier The designated bridge to which the root port is connected. The designated
bridge is the device that connects the network segment on the port to the root
bridge.
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.
Max Age sec The number of seconds this root bridge waits for a hello message from the
bridges before deciding a bridges has become unavailable and performing a
reconvergence.
Hello sec The interval between each configuration BPDU sent by the root bridge.
FwdDly sec The number of seconds this root bridge waits following a topology change and
consequent reconvergence.
Port STP Parameters
Port Num The port number.
Priority The port’s STP priority.
NOTE: If you configure this value, specify it in decimal format. Refer to
“Changing STP port parameters” .
Path Cost The port’s STP path cost.
