2.4 How to Use Error Disable and Recovery on the Switch

This tutorial shows you how to shut down a port when:
• a loop has occurred
or
• too many ARP requests (over 100 packets per second) have been received on a port
You also want the Switch to wait for a period of time (10 minutes) before resuming the port
automatically, after the problem(s) are gone. Loop guard and Errdiable features are helpful for this
demand.
Note: Refer to
information about Loop Guard and Errdiable.
To configure the settings:
First, click Advanced Application > Loop Guard. Select the Active option in the first section to
1
enable loop guard on the Switch. Then select the Active option of the first entry (port *) to enable
loop guard for all ports. Click Apply.
