Munir,

I have attached a snapshot for your reference, the one which i have encircled.

In addition to it, check the "show logs" on the switch for checking the link flaps.

Hi Munir,

Flapping implies that the port is going up and down very quickly. The logs should show this with a time stamp. The commands provided above will also provide the last time it went down and came up along with a counter for how many times. This data is typically cleared after a reboot or if the command "clear counters" is entered.
