For example, configure Loopback Detection on the Alcatel OmniStack LS 6224 switch.
Let’s look at the current settings for Loopback Detection:
enable show loopback-detection
Let’s go into the configuration mode, enable and specify some parameters of Loopback Detection:
configure loopback-detection enable loopback-detection mode src-mac-addr loopback-detection interval 30
Turn on the client ports Loopback Detection:
interface range ethernet e1-24,g2-4 loopback-detection enable exit
g1 I have an uplink, so I did not enable Loopback Detection on it.
Let’s configure automatic activation of the port after 3000 seconds, if it was turned off due to the loop (you can specify the value in seconds 30-86400, standard 300):
errdisable recovery interval 3000 errdisable recovery cause loopack-detection show errdisable recovery show errdisable interfaces
Exit the configuration mode and save the configuration:
exit copy running-config startup-config
