statBridgeBridgeRootCost
Module: CLEARTRAC7-MIB
OID (symbolic): CLEARTRAC7-MIB::statBridgeBridgeRootCost
OID (numeric): 1.3.6.1.4.1.727.7.2.20.5.1.4
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: From each unit there are potentially many different paths to the root bridge. The root cost is the lowest path cost, that is, the shortest relative path length to the root bridge. When the root cost is displayed as zero (0), either this unit is the root bridge or there is no direct path from this unit to the root bridge.
What is statBridgeBridgeRootCost?
This read-only value reports the lowest-cost path length from this unit to the spanning-tree root bridge, with a value of zero meaning either this unit is the root itself or no direct path to the root currently exists. An administrator uses it to gauge how topologically far a given bridge is from the root and to spot units that have lost their path entirely. For example, if statBridgeBridgeRootCost suddenly reads zero on a unit that is known not to be the root, the administrator would recognize the unit has become isolated from the spanning tree and investigate the uplink.
