ctPvstStpVlanId
Module: CTRON-BRIDGE-MIB
OID (symbolic): CTRON-BRIDGE-MIB::ctPvstStpVlanId
OID (numeric): 1.3.6.1.4.1.52.4.1.2.3.2.2.5.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The VLAN-ID of the VLAN on which this spanning tree is running. Writing a VLAN-ID will create a separate spanning tree for that VLAN, if it previously was part of the single 802.1Q VLAN.
What is ctPvstStpVlanId?
This read-write integer, ranging 1 to 4094, identifies which VLAN a particular Per-VLAN Spanning Tree instance is running for, and writing a new VLAN-ID here splits that VLAN out of the shared 802.1Q tree into its own dedicated spanning tree. An administrator uses it to selectively give specific VLANs independent loop-prevention topology and blocking-port decisions rather than sharing one tree for everything. For example, to give a latency-sensitive voice VLAN its own fast-converging spanning tree separate from the data VLANs, the admin writes that VLAN's ID into this object to create a dedicated instance.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.3.2.2.5.1.1 snmpwalk -v2c -c public <target> CTRON-BRIDGE-MIB::ctPvstStpVlanId
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.3.2.2.5.1.1.1 snmpget -v2c -c public <target> CTRON-BRIDGE-MIB::ctPvstStpVlanId.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.1.2.3.2.2.5.1.1.1 i <value>
