Chapter 1 Port Basic Configuration
Commands
1-30
Use the
undo loopback-detection shutdown enable
command to disable the
function.
The loopback port auto-shutdown function works in conjunction with the loopback
detection function (refer to
loopback-detection enable
). If a loop is found at a port:
z
With the function enabled on the port, the system will shut down the port, and send
log messages to the terminal. After the loop is removed, you need to use the
undo
shutdown
command to bring up the port.
z
With the function disabled on the port, the system will only send log messages to
the terminal, and the port is still in the normal forwarding state.
By default, the loopback port auto-shutdown function is enabled on ports if the device
boots with the default configuration file (config.def); if the device boots with null
configuration, this function is disabled.
Related command:
loopback-detection control enable
.
Note:
You cannot enable both the loopback port control function (with the
loopback-detection
control enable
command) and the loopback port auto-shutdown function on a port. If
you do so, the function configured later will take effect.

# Enable the loopback port auto-shutdown function on port Ethernet 1/0/1.
