vlanTrunkPortVlansXmitJoined2k
Module: CISCO-VTP-MIB
OID (symbolic): CISCO-VTP-MIB::vlanTrunkPortVlansXmitJoined2k
OID (numeric): 1.3.6.1.4.1.9.9.46.1.6.1.1.23
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description:
A string of octets containing one bit per VLAN for VLANS with VlanIndex values of 1024 through 2047 in the management domain on this trunk port. The first octet corresponds to VLANs with VlanIndex values of 1024 through 1031; the second octet to VLANs 1032 through 1039; etc. The most significant bit of each octet corresponds to the lowest value VlanIndex in that octet.
If the bit corresponding to a VLAN is set to '1', then this VLAN is presently being forwarded on this trunk port, i.e., it is not pruned; if the bit is set to '0', then this VLAN is presently not being forwarded on this trunk port, either because it is pruned or for some other reason.
What is vlanTrunkPortVlansXmitJoined2k?
This object is a bit string representing which VLANs with IDs 1024-2047 are actively transmitting traffic across a trunk port in Cisco VTP (VLAN Trunking Protocol), with each bit corresponding to a specific VLAN. The first octet covers VLANs 1024-1031, the second covers 1032-1039, and so on, with the most significant bit indicating the lowest VLAN ID in that octet. Network engineers use this to verify which higher-numbered VLANs are actively carrying traffic on trunk links and to troubleshoot VLAN propagation issues.
