vlanTrunkPortVlansRcvJoined

Module: CISCO-VTP-MIB

OID (symbolic): CISCO-VTP-MIB::vlanTrunkPortVlansRcvJoined

OID (numeric): 1.3.6.1.4.1.9.9.46.1.6.1.1.12

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: A string of octets containing one bit per VLAN in the management domain on this trunk port. The first octet corresponds to VLANs with VlanIndex values of 0 through 7; the second octet to VLANs 8 through 15; 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 the local switch is currently sending joins for this VLAN on this trunk port, i.e., it is asking to receive frames for this VLAN; if the bit is set to '0', then the local switch is not currently sending joins for this VLAN on this trunk port.

What is vlanTrunkPortVlansRcvJoined?

This read-only bitmap reports, one bit per VLAN, which VLANs this local switch is currently sending VTP join messages for on a specific trunk port, using the same one-bit-per-VLAN octet layout as the transmit-joined bitmap. An administrator compares this against vlanTrunkPortVlansXmitJoined to understand the local switch's active pruning-related signaling state per VLAN on that trunk. For example, a VLAN whose bit is set here indicates the local switch is actively requesting that VLAN's traffic over this trunk, consistent with having local ports or devices needing it.
