swMSTPInstMaxAge
Module: MSTP-MIB
OID (symbolic): MSTP-MIB::swMSTPInstMaxAge
OID (numeric): 1.3.6.1.4.1.171.12.15.2.3.1.19
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The maximum age of Spanning Tree Protocol information learned from the network on any port before it is discarded, in units of hundredths of a second. This is the actual value that this bridge is currently using.
What is swMSTPInstMaxAge?
This read-only value reports the actual MaxAge (in hundredths of a second) this bridge is currently using for this instance's spanning tree information before discarding it, as opposed to the configured swMSTPStpMaxAge value which only applies when acting as root. Admins compare this to the configured value to see what MaxAge was actually inherited from the network.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.3.1.19 snmpwalk -v2c -c public <target> MSTP-MIB::swMSTPInstMaxAge
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.15.2.3.1.19.1 snmpget -v2c -c public <target> MSTP-MIB::swMSTPInstMaxAge.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> swMSTPInstMaxAge.1
