ieee8021SpanningTreePortForwardTransitions
Module: IEEE8021-SPANNING-TREE-MIB
OID (symbolic): IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreePortForwardTransitions
OID (numeric): 1.3.111.2.802.1.1.3.1.2.1.11
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The number of times this port has transitioned from the Learning state to the Forwarding state.
Discontinuities in the value of the counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime object of the associated interface (if any).
What is ieee8021SpanningTreePortForwardTransitions?
Count of times this port has moved from Learning to Forwarding state; a rapidly increasing counter on a port that should be stable indicates repeated STP recalculation or a flapping link.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.3.1.2.1.11 snmpwalk -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreePortForwardTransitions
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.3.1.2.1.11.1 snmpget -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreePortForwardTransitions.1
