XGS3 Command Guide
6-145
MAC address of the port.
Default:
Disable the function of loopback diction control.
Command Mode:
Port Mode.
Usage Guide:
If there is any loopback, the port will not recovery the state of be controlled after enabling control operation on the
port. If the overtime is configured, the ports will recovery normal state when the overtime is time-out. If the control
method is block, the corresponding relationship between instance and vlan id should be set manually by users, it
should be noticed when be used.
Example:
Enable the function of loopback detection control under port1/0/2 mode.
Switch(config)#interface ethernet 1/0/2
Switch(Config-If-Ethernet1/0/2)#loopback-detection control shutdown
Switch(Config-If-Ethernet1/0/2)#no loopback-detection control
6.3 loopback-detection control-recovery timeout
Command:
loopback-detection control-recovery timeout <0-3600>
Function:
This command is used to recovery to uncontrolled state after a special time when a loopback being detected by the
port entry be controlled state.
Parameters:
<0-3600> second is recovery time for be controlled state, 0 is not recovery state.
Default:
The recovery is not automatic by default.
Command Mode:
Global Configuration Mode.
Usage Guide:
When a port detects a loopback and works in control mode, the ports always work in control mode and not recover.
The port will not sent packet to detection in shutdown mode, however, the port will sent loopback-detection packet to
detection whether have loopback in block or learning mode. If the recovery time is configured, the ports will recovery
normal state when the overtime is time-out. The recovery time is a useful time for shutdown control mode, because
the port can keep on detection loopback in the other modes, so suggest not to use this command.
Example:
Enable automatic recovery of the loopback-detection control mode after 30s.
