vlanSpanningTreeSwitchRootPortTime
Module: CTRON-SFPS-VSTP-MIB
OID (symbolic): CTRON-SFPS-VSTP-MIB::vlanSpanningTreeSwitchRootPortTime
OID (numeric): 1.3.6.1.4.1.52.4.2.12.1.2.8.2.1.1.8
Node type: OBJECT-TYPE
Type: TimeTicks
Access: read-only
Description: Spanning tree root port time.
What is vlanSpanningTreeSwitchRootPortTime?
Reports, in TimeTicks, how long the current root port has held that role. An admin uses this to judge topology stability, since a root port that keeps changing frequently indicates an unstable or flapping link.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.12.1.2.8.2.1.1.8 snmpwalk -v2c -c public <target> CTRON-SFPS-VSTP-MIB::vlanSpanningTreeSwitchRootPortTime
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.12.1.2.8.2.1.1.8.1 snmpget -v2c -c public <target> CTRON-SFPS-VSTP-MIB::vlanSpanningTreeSwitchRootPortTime.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> vlanSpanningTreeSwitchRootPortTime.1
