Change a port from stauts/protocol down

[jpozo0001]

Hello,

I have two switches WS-C3750G-24TS and i had an interlink between them through a port channel containing both ports g1/0/23 and 24. Then all of a sudden when i noticed the interlink was status down and protocol down. I have shutdown and no shutdown, change the cables, interconnect one pair of ports to a different port to notice that the ports are still good and they still are. I have checked the operation mode and it is also down. Any one has any idea how I can bring the ports back up? The config is the same on both ports. Any help would be appreciated. Thank you.

Post the complete output to the command "sh interface <BLAH>".

This is the same on both switches

The output is NOT what I requesting. 

Post the complete output to the command "sh interface <BLAH>".

This is the first time I see that command. Is the <BLAH> replaced with something else because the command is invalid when entered.

I think instead of the running config Leo is looking for the actual full show outputs from the router interfaces to be posted to get a better understanding of the errors that may be there and may have caused the issue

best to provide from both switches each side

also does anything show in either side switch logs anything for those ports around the time of the failure , you can check with command -- show log

show int po1

show int g1/0/23

show int g1/0/24
