vlanTrunkPortVlansRcvJoined2k
Module: CISCO-VTP-MIB
OID (symbolic): CISCO-VTP-MIB::vlanTrunkPortVlansRcvJoined2k
OID (numeric): 1.3.6.1.4.1.9.9.46.1.6.1.1.26
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 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 vlanTrunkPortVlansRcvJoined2k?
This OID contains a bitmap where each bit represents whether a specific VLAN (network segment) numbered 1024-2047 is active on this trunk port. Reading it shows which network segments are currently allowed to pass through this connection point between switches. A network admin checks this when verifying that the correct network segments are configured on a switch-to-switch link.
