dot1dStpBridgeMaxAge
Module: BRIDGE-MIB
OID (symbolic): BRIDGE-MIB::dot1dStpBridgeMaxAge
OID (numeric): 1.3.6.1.2.1.17.2.12
Node type: OBJECT-TYPE
Type: Timeout
Access: read-write
Description: Bridge max age.
What is dot1dStpBridgeMaxAge?
The Maximum Age value (in hundredths of a second) that this bridge advertises to all other bridges when it is acting as the STP root, determining how long bridges retain STP topology information before discarding it. Administrators can tune this to balance network stability against convergence speed.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.17.2.12 snmpwalk -v2c -c public <target> BRIDGE-MIB::dot1dStpBridgeMaxAge
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.17.2.12.1 snmpget -v2c -c public <target> BRIDGE-MIB::dot1dStpBridgeMaxAge.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.17.2.12.1 s <value>
