prvtStMaxAge
Module: PRVT-SPANNING-TREE-MIB
OID (symbolic): PRVT-SPANNING-TREE-MIB::prvtStMaxAge
OID (numeric): 1.3.6.1.4.1.738.1.5.107.1.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The maximum age, in seconds, of Spanning Tree Protocol information learned from the network on any port before it is discarded. Note that the following relationships are enforced: prvtStMaxAge >= 2 x (prvtStHelloTime + 1) 2 x (prvtStForwardDelay - 1) >= prvtStMaxAge
What is prvtStMaxAge?
How many seconds STP information learned from the network is kept on a port before being discarded (6-40s); the MIB enforces prvtStMaxAge >= 2*(prvtStHelloTime+1) and 2*(prvtStForwardDelay-1) >= prvtStMaxAge, so changing Hello Time or Forward Delay can force this value to be adjusted too.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.738.1.5.107.1.1.2 snmpwalk -v2c -c public <target> PRVT-SPANNING-TREE-MIB::prvtStMaxAge
Get a specific instance (index 1):
