Description: In an MSTP Bridge, the current state of the Port (i.e., Disabled, Listening, Learning, Forwarding, or Blocking), for the MSTI.
What is ieee8021MstpPortState?
The port's current forwarding state for this MST Instance: disabled(1), listening(2), learning(3), forwarding(4), or blocking(5) — a port stuck in listening or learning for a long time on a given instance usually points to a spanning-tree convergence problem specific to that VLAN group.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.4.1.5 snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpPortState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.4.1.5.1 snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpPortState.1
