Node type: OBJECT-TYPE
Type: TimeTicks
Access: read-only
Description: Spanning tree previous root port time.
What is vlanSpanningTreeSwitchPrevRootPortTime?
Reports, in TimeTicks, how long the previous root port held that role before the switch elected its current root port. An admin uses this alongside vlanSpanningTreeSwitchPrevRootPort to gauge how long the prior topology was stable before it changed.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.12.1.2.8.2.1.1.10 snmpwalk -v2c -c public <target> CTRON-SFPS-VSTP-MIB::vlanSpanningTreeSwitchPrevRootPortTime
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.12.1.2.8.2.1.1.10.1 snmpget -v2c -c public <target> CTRON-SFPS-VSTP-MIB::vlanSpanningTreeSwitchPrevRootPortTime.1
