etsysMstpTimeSinceTopologyChange
Module: ENTERASYS-MSTP-MIB
OID (symbolic): ENTERASYS-MSTP-MIB::etsysMstpTimeSinceTopologyChange
OID (numeric): 1.3.6.1.4.1.5624.1.2.28.1.2.4.1.2
Node type: OBJECT-TYPE
Type: TimeTicks
Access: read-only
Description: The elapsed time, in units of hundredths of a second, since the last time a topology change was detected by the corresponding Spanning Tree instance (specifically, the elapsed time since the tcWhile timer for any port was non-zero).
What is etsysMstpTimeSinceTopologyChange?
Counts hundredths of a second since the last topology change was detected on this MST instance, giving admins a quick way to see how recently the network topology last shifted, e.g. a link flap or failover.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5624.1.2.28.1.2.4.1.2 snmpwalk -v2c -c public <target> ENTERASYS-MSTP-MIB::etsysMstpTimeSinceTopologyChange
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5624.1.2.28.1.2.4.1.2.1 snmpget -v2c -c public <target> ENTERASYS-MSTP-MIB::etsysMstpTimeSinceTopologyChange.1
