dVlanPortIfTagAllowVlanLstFirst2K
Module: DLINKSW-VLAN-MIB
OID (symbolic): DLINKSW-VLAN-MIB::dVlanPortIfTagAllowVlanLstFirst2K
OID (numeric): 1.3.6.1.4.1.171.26.21.1.4.1.5
Node type: OBJECT-TYPE
Type: Dlink2kVlanList
Access: read-write
Description: This object specifies the VLANs in a string of octets containing one bit per VLAN for VLANs 1 to 2048.
If the bit is set to '1', then the interface is allowed to be the VLAN's tagged member.
Note: This value is meaningful only when the VLAN mode of the port is 'hybrid' or 'trunk'.
What is dVlanPortIfTagAllowVlanLstFirst2K?
This value is a bitmap, one bit per VLAN, covering VLAN IDs 1 through 2048, that specifies which of those VLANs a hybrid or trunk port is permitted to carry as a tagged member. An admin uses it to precisely control tagged VLAN membership on the port, complementing the separate untagged-allow list. For example, setting the bit for VLAN 100 lets the port forward and accept tagged frames for VLAN 100 while other unlisted VLANs in that range remain excluded from tagged membership.
