accStpForwardDelay
Module: ACC-MIB
OID (symbolic): ACC-MIB::accStpForwardDelay
OID (numeric): 1.3.6.1.4.1.5.1.1.2.15
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The time (seconds) spent in the Listening state while moving from the Blocking state to the Learning state. The time (seconds) spent in the Learning state while moving from the Listening state to the Forwarding state. The value (seconds) used for the ageing time of dynamic entries in the Forwarding Database table wile the Topology Change flag is set in protocol messages received from the Root.
What is accStpForwardDelay?
This OID stores the duration (in seconds, range 5–3600) that a port spends in the Listening and Learning states while transitioning through the spanning tree protocol, and also sets the aging time for dynamic bridge database entries during network topology changes. Network engineers configure this value to control how quickly the spanning tree protocol converges when links fail or change state—longer delays mean slower convergence but more stability, while shorter delays speed up network failover. A typical value of 15 seconds means each port state transition takes about 15 seconds, resulting in roughly 30 seconds total convergence time across the bridge.

Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5.1.1.2.15 snmpwalk -v2c -c public <target> ACC-MIB::accStpForwardDelay
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5.1.1.2.15.1 snmpget -v2c -c public <target> ACC-MIB::accStpForwardDelay.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.5.1.1.2.15.1 i <value>
