swLoopDetectPortLoopVLAN
Module: LOOPBACK-DETECT-MIB
OID (symbolic): LOOPBACK-DETECT-MIB::swLoopDetectPortLoopVLAN
OID (numeric): 1.3.6.1.4.1.171.12.41.3.1.1.3
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: This object indicates the VLAN list that has detected a loopback.
What is swLoopDetectPortLoopVLAN?
This value lists the VLANs on which a loopback has been detected for this port. Admins read it, in VLAN-based detection mode, to see exactly which VLAN's traffic is looping back on a flagged port rather than just knowing the port itself is affected. For example, a value of "10,20" would tell the admin loops were detected on VLANs 10 and 20 on this port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.41.3.1.1.3 snmpwalk -v2c -c public <target> LOOPBACK-DETECT-MIB::swLoopDetectPortLoopVLAN
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.41.3.1.1.3.1 snmpget -v2c -c public <target> LOOPBACK-DETECT-MIB::swLoopDetectPortLoopVLAN.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> swLoopDetectPortLoopVLAN.1
