Switching

Is there a way to find out when was the last time an interface was up?

Thanks

Hi,

I could be wrong, but I believe the closest match is "Last flapped" using "show interfaces xx-x/x/x media".  I hope this helps.

I was thinking of something equivalent cisco's "show interface link", but "last flapped" seems to be enough. Thanks
