dVlanPortIfUntagAllowVlanLstFirst2K
Module: DLINKSW-VLAN-MIB
OID (symbolic): DLINKSW-VLAN-MIB::dVlanPortIfUntagAllowVlanLstFirst2K
OID (numeric): 1.3.6.1.4.1.171.26.21.1.4.1.7
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 untagged member.
Note: This value is meaningful only when the VLAN mode of the port is 'hybrid' or 'trunk'.
What is dVlanPortIfUntagAllowVlanLstFirst2K?
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 an untagged member. An admin uses it to let a port send and receive certain VLANs without 802.1Q tags, typically for legacy end devices that can't handle tagged frames. For example, setting the bit for VLAN 10 lets an untagged legacy device on that port participate in VLAN 10 without needing a tag-aware network card.
