Faulty Interface down logs, is it bug?

[eeebbunee]

Hello everyone,

I'm not sure some of you maybe having an same issue with me, about weird logs.

Yesterday, there were switch logs about interface down.

On the switch logs (sh log) 5 interface ports has been down, but we don't have interface connections on those ports.

We used to have the connections on that ports, but we moved connections about 4 month ago.

We didn't plugged new connection on those ports, since last 4 months, so there was no log about interface up but suddenly interface down logs happened.

   - Switch2: WS-C3750X-12S (Fiber switch)
   - OS: 15.0(2)SE10a
   - SW image: C3750E-UNIVERSALK9-M 

Is this just bug? Do you think we need to upgrade our software image?

It seems switch working fine with other active ports, but just concerned.. 

Thank you for your comment!

Hello @balaji.bandi ,

Thank you for reaching my conversation.

switch uptime is more than 5 years. Our company runs 24x7, so I need to make a reboot schedule.

I will follow your comment, much appreciated!

yes i am sure you get a maintenance window and reboot and report back.

Looks like someone cut the power to those clients.
