bridgeDomainBridgeForwardDelay

Module: ACMIB

OID (symbolic): ACMIB::bridgeDomainBridgeForwardDelay

OID (numeric): 1.3.6.1.4.1.1751.2.18.5.9.1.15

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The value that all bridges user for ForwardDelay when this bridge is acting as the root. Note that 802.1D-1990 specifies that the range for this parameter is related to the value of bridgeDomainMaxBridgeAge. The granularity of this timer is specified by 802.1D-1990 to be 1 second. An agent may return a badValue error if a set is attempted to a value which is not a whole number of seconds.

What is bridgeDomainBridgeForwardDelay?

This OID configures the forward delay (4–30 seconds) that applies when this bridge is the spanning tree root, controlling how fast ports transition through learning states. Engineers set this on the root to tune the network's overall convergence behavior; smaller values speed up traffic resumption but risk transient loops. Setting it to 15 seconds is a common middle-ground configuration.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.9.1.15
snmpwalk -v2c -c public <target> ACMIB::bridgeDomainBridgeForwardDelay

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.9.1.15.1
snmpget -v2c -c public <target> ACMIB::bridgeDomainBridgeForwardDelay.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.9.1.15.1 i <value>
