Description: The number of times this Bridge has detected a Root Identifier change. A Trap is generated on the occurence of this event.
What is nnRstDot1wNewRootIdCount?
Counts how many times this bridge has seen the spanning-tree root bridge change, with each change also firing the nnRstNewRoot trap; a rising count indicates topology instability an admin should investigate.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.4.1.2.1.3 snmpwalk -v2c -c public <target> NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1wNewRootIdCount
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.4.1.2.1.3.1 snmpget -v2c -c public <target> NORTEL-NETWORKS-RAPID-SPANNING-TREE-MIB::nnRstDot1wNewRootIdCount.1
