swLoopDetectAdminState
Module: LOOPBACK-DETECT-MIB
OID (symbolic): LOOPBACK-DETECT-MIB::swLoopDetectAdminState
OID (numeric): 1.3.6.1.4.1.171.12.41.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object indicates the loopback detection status for the system.
What is swLoopDetectAdminState?
This value enables or disables the switch's loopback detection (LBD) feature system-wide, choosing between enabled(1) and disabled(2). Admins turn it on to have the switch automatically detect and react to cabling loops caused by accidental cross-connects. Setting it to disabled(2) would turn off loop detection entirely, which an admin might do temporarily while intentionally testing loopback cabling.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.41.1.1 snmpwalk -v2c -c public <target> LOOPBACK-DETECT-MIB::swLoopDetectAdminState
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.41.1.1.1 snmpget -v2c -c public <target> LOOPBACK-DETECT-MIB::swLoopDetectAdminState.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.41.1.1.1 i <value>
