Interface Uptime

[s.kanth]

Is there any command to find out how long a perticulater interface has been up ? (Example BVI interface on AP, serial interface )

Im just going to throw this one out there. 
But

show dtp interface [type]{number}

regardless of if you use DTP or not will show you the date that an interface last went up and down. 
show dtp interface TwentyFiveGigE1/0/10
   [--output omitted--]
   3 link ups, last link up on Mon Nov 27 2023, 08:20:27
   2 link downs, last link down on Mon Nov 27 2023, 08:16:32

Use a -real- switch like Nexus series...

sh int eth1/6
>> Last link flapped 5week(s) 0day(s)

But i agree, this should be standard by now.
