dLbdIfLoopVlans
Module: DLINKSW-LBD-MIB
OID (symbolic): DLINKSW-LBD-MIB::dLbdIfLoopVlans
OID (numeric): 1.3.6.1.4.1.171.26.46.1.4.1.4
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: This object indicates the VLAN list that has detected a loopback.
What is dLbdIfLoopVlans?
This read-only string lists the VLANs on which a loopback has been detected for a given interface. Admins use it in VLAN-based detection mode to know precisely which VLANs on a trunk port are looped, rather than assuming the entire port is affected. A dLbdIfLoopVlans value of "10,20" on a trunk port tells the admin the loop is confined to VLANs 10 and 20, while other VLANs on that same port remain unaffected.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.26.46.1.4.1.4 snmpwalk -v2c -c public <target> DLINKSW-LBD-MIB::dLbdIfLoopVlans
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.26.46.1.4.1.4.1 snmpget -v2c -c public <target> DLINKSW-LBD-MIB::dLbdIfLoopVlans.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dLbdIfLoopVlans.1
