dLbdVlanCrlFirst2K
Module: DLINKSW-LBD-MIB
OID (symbolic): DLINKSW-LBD-MIB::dLbdVlanCrlFirst2K
OID (numeric): 1.3.6.1.4.1.171.26.46.1.5.1
Node type: OBJECT-TYPE
Type: Dlink2kVlanList
Access: read-write
Description: This object specifies the loopback detection enabled VLAN in a string of octets containing one bit per VLAN for VLANs 1 to 2048. If the bit is set to '1', then the VLAN is enabled for loopback detection.
What is dLbdVlanCrlFirst2K?
This read-write bitmap specifies which VLANs from 1 to 2048 have loopback detection enabled, with one bit per VLAN. Admins set specific bits in this string to restrict LBD control packets to selected VLANs rather than every VLAN a port is a member of, which is useful for scoping loop protection to production VLANs only. Setting the bit corresponding to VLAN 100 in dLbdVlanCrlFirst2K enables loopback detection on VLAN 100 specifically, while leaving VLAN 200 unaffected unless its own bit is also set.
Examples
