tnTopologyChangeSapMajorState
Module: TN-SAP-MIB
OID (symbolic): TN-SAP-MIB::tnTopologyChangeSapMajorState
OID (numeric): 1.3.6.1.4.1.7483.6.1.3.4.5.0.1
Node type: NOTIFICATION-TYPE
Description:
The tnTopologyChangeSapMajorState notification is generated when a SAP has transitioned its state from learning to forwarding or from forwarding to blocking or broken. The spanning tree topology has been modified and it may denote loss of customer access or redundancy. Check the new topology against the provisioned topology to determine the severity of connectivity loss.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' TN-SAP-MIB::tnTopologyChangeSapMajorState snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.7483.6.1.3.4.5.0.1
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
