Hi everyone,
I purchased a brand new Cisco 2911 Router and when connecting everything together I noticed an issue with my gi0/1.
When I issue a no shut on both interfaces the port Gi1/0/12 would intermittently blink amber once and then go off, and it would continue to do so and would never connect the interface.

I have yet to see any counters increase. I swapped out the cable several times with new Cat6 cables and still no luck. Any insight would be greatly appreciated. Would be unfortunately for this brand new, never opened device would have a dead port.
Thanks!
