Cisco 3560 interface, not connected

[Steve Coady]

Hello

I am in the process of determining available switch ports based on last usage and I came across the following that I don't understand.

Switch-3560G-1#sh int | I Last|Gig
 

GigabitEthernet0/7 is down, line protocol is down (notconnect)
  Hardware is Gigabit Ethernet, address is 0014.a98f.ba87 (bia 0014.a98f.ba87)
  Last input never, output 21:56:52, output hang never
  Last clearing of "show interface" counters never

The interface, notconnnect status, has a last output value is that is incrementing.

what could be causing this?

It means that the physical interface is down and the list time the switch saw any traffic (even though it's a one-way traffic) is almost 22 hours ago.

Thank you for the response.

The interface shows down/down, but the counters are incrementing!?! seems strange

If the interface is down/down and counters are incrementing then I'm suspecting you could be seeing an IOS bug.
