dLbdCtrlMode
Module: DLINKSW-LBD-MIB
OID (symbolic): DLINKSW-LBD-MIB::dLbdCtrlMode
OID (numeric): 1.3.6.1.4.1.171.26.46.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object indicates the loopback detection mode. portBased(1) - The loopback detection works in port-based mode. vlanBased(2) - The loopback detection works in vlan-based mode.
What is dLbdCtrlMode?
This read-write value selects whether loopback detection operates in port-based mode or VLAN-based mode. Admins choose portBased(1) for simple per-port loop checking, or vlanBased(2) when they need loop detection scoped to specific VLANs, such as in a trunked environment with multiple VLANs per port. Setting dLbdCtrlMode to vlanBased(2) allows the switch to detect and block a loop on one VLAN over a trunk port without disabling the entire physical port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.26.46.1.3 snmpwalk -v2c -c public <target> DLINKSW-LBD-MIB::dLbdCtrlMode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.26.46.1.3.1 snmpget -v2c -c public <target> DLINKSW-LBD-MIB::dLbdCtrlMode.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.26.46.1.3.1 i <value>
