accBrPortState
Module: ACC-MIB
OID (symbolic): ACC-MIB::accBrPortState
OID (numeric): 1.3.6.1.4.1.5.1.1.3.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: accBrPortState reports the operational status of the port; it is writable for backward compatibility (writes also update accBrPortAdminStatus). disabled(0), blocking(1), listening(2), learning(3), forwarding(4)
What is accBrPortState?
This field reports and allows control of the port's operational state in the spanning tree (0=disabled, 1=blocking, 2=listening, 3=learning, 4=forwarding). Network engineers check this to ensure ports are transitioning properly through spanning tree states; a port stuck in blocking state when it should be forwarding indicates a protocol problem. A healthy root port should show state 4 (forwarding), while alternate or backup ports typically remain in state 1 (blocking).
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5.1.1.3.1.5 snmpwalk -v2c -c public <target> ACC-MIB::accBrPortState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5.1.1.3.1.5.1 snmpget -v2c -c public <target> ACC-MIB::accBrPortState.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.5.1.1.3.1.5.1 i <value>
