What is dot1qPortAllowedVlans?
This OCTET STRING encodes the bitmap of VLAN IDs permitted to pass over this trunk port. Admins configure this to restrict a trunk to only the VLANs that should legitimately traverse it, preventing unwanted VLANs from leaking across the link. For instance, an admin trunking only VLANs 10, 20, and 30 to a downstream switch would set the corresponding bits in this bitmap and leave all other VLAN bits cleared.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11606.10.9.182.3.1.4 snmpwalk -v2c -c public <target> NMS-VLAN-EXT-MIB::dot1qPortAllowedVlans
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11606.10.9.182.3.1.4.1 snmpget -v2c -c public <target> NMS-VLAN-EXT-MIB::dot1qPortAllowedVlans.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.11606.10.9.182.3.1.4.1 s <value>
