ctPvstStpPortVlanId
Module: CTRON-BRIDGE-MIB
OID (symbolic): CTRON-BRIDGE-MIB::ctPvstStpPortVlanId
OID (numeric): 1.3.6.1.4.1.52.4.1.2.3.2.2.6.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The VLAN-ID of the VLAN on which this spanning tree is running.
What is ctPvstStpPortVlanId?
This read-only integer, ranging 1 to 4094, identifies the VLAN associated with the spanning tree instance that this port-level row describes. An administrator uses it to map a given port's per-VLAN STP state, such as its role or path cost, back to the correct VLAN when a port participates in multiple PVST instances. For example, when a trunk port shows unexpected blocking behavior, the admin checks this object on each relevant row to determine which VLAN's spanning tree is responsible for blocking that particular VLAN's traffic on the port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.3.2.2.6.1.1 snmpwalk -v2c -c public <target> CTRON-BRIDGE-MIB::ctPvstStpPortVlanId
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.3.2.2.6.1.1.1 snmpget -v2c -c public <target> CTRON-BRIDGE-MIB::ctPvstStpPortVlanId.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ctPvstStpPortVlanId.1
