Parameters
vlan-list: Specifies a VLAN list, in the format of { vlan-id [ to vlan-id ] }&<1-10>, where vlan-id
represents the VLAN ID in the range of 1 to 4094, and &<1-10> indicates that you can specify up to
10 vlan-id [ to vlan-id ] parameters.
all: Specifies all existing VLANs.
Usage guidelines
The port-specific loop detection configuration takes effect only after you enable loop detection
globally. To enable loop detection globally, use the loopback-detection global enable command.
The global configuration applies to all ports in the specified VLAN. The per-port configuration applies
to the individual port only when the port belongs to the specified VLAN. The per-port configuration
takes precedence over the global configuration.
Example
# Enable loop detection on port GigabitEthernet 1/0/1 for VLAN 10 through VLAN 20.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[System-GigabitEthernet1/0/1] loopback-detection enable vlan 10 to 20
Related commands
• display loopback-detection
• loopback-detection global enable
loopback-detection global action
Use loopback-detection global action to configure the global loop protection action.
Use undo loopback-detection global action to restore the default.
Syntax
loopback-detection global action shutdown
undo loopback-detection global action
Default
When the device detects a loop on a port, it generates a log but performs no action on the port.
