bridgeDomainMaxBridgeAge
Module: ACMIB
OID (symbolic): ACMIB::bridgeDomainMaxBridgeAge
OID (numeric): 1.3.6.1.4.1.1751.2.18.5.9.1.13
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The value that all bridges use for MaxAge 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 bridgeDomainBridgeHelloTime. 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 bridgeDomainMaxBridgeAge?
This OID stores the maximum age threshold (6–40 seconds) for spanning tree information when this bridge is acting as the STP root. Engineers adjust this on the root bridge to control how quickly stale topology data is purged across the entire network. Setting this to 20 seconds ensures all bridges discard outdated STP information every 20 seconds.
