Hi, im Victor and im having two problems in a switch, from one side i have a switch A te2/0/2 connected to a Switch B te2/0/2, the switch sometimes blink orange Green, and sometimes is blinking Green only. If the port ar runing a few hours, it suddenly stops to work and inthe side B the port goes to err-disabled.
Both switch are cisco 2960x and are running 15.2(2)E3, the fiberoptic are about 500 ft of lenght, with Belden Patchcord FT4 of 9.8ft with gbix SFP-10G-SR.

Can you help me to check if someting is wrong? or if i need to configure anything else on the interface? both are wi this configuration:
interface TenGigabitEthernet2/0/2
description Redundant Link to SSRAMSWAL003 Te2/0/2
switchport mode trunk
By other side, i have the switch A connected to my core switch and the same situation, are not working OK, the weird thing is that was working ok and that the B switch has the same configuration and versions and are connected to the same switch and are working OK.
This is the info for this interface gi1/0/49 from A switch, note, i just reset it about a 20 minutes ago.....
