16.2.3 Configuring the port reset function

An uplink port for which the port reset function is set causes the old active port to temporarily go down when the active port is switched.

Points to note

If port 1/0/1 is set as the primary port and port 1/0/2 is set as the secondary port, the port reset function is set to port 1/0/1, which is the primary port.

Also, set the port down time in 5 seconds. The default is 3 seconds, but it must be longer than the link-down detection time of the partner switch (for example, when link debounce equivalent of the Switch's configuration command is set).

Command examples

1. (config)# interface gigabitethernet 1/0/1

   (config-if)# switchport backup reset-flush-port

   (config-if)# switchport backup reset-flush-time 5

   (config-if)# exit

   Switches to the configuration mode of port 1/0/1, which is the primary port, and sets the port reset function. Also, set the port down time in 5 seconds.
