loop-detect trigger detection

Function

The loop-detect trigger detection command sets a VLAN range for a main interface to send proactive loop detection packets.

The undo loop-detect trigger detection command disables a main interface from sending proactive loop detection packets with the specified VLAN range.

By default, a main interface sends only untagged packets and packets with the VLAN ID of 0.

Usage Guidelines

Usage Scenario

After proactive loop detection upon interface Up is enabled both in the system view and in the interface view, you can run the loop-detect trigger detection command to set a VLAN range for the interface to send proactive loop detection packets.

Precautions

You can use this command to configure a maximum of eight VLAN ranges or VLAN IDs.

Example

# Configure GE 0/1/0 to send proactive loop detection packets with VLAN IDs ranging from 3 to 100.
