Hi,
I have a switch 2960-24TC-L with GEC (realised with 2 giga interface uplink) with switch 3750.
the configuration is ok, the GEC is up and other feature working.
I try to upgrade 2960-24TC-L from 12.2.44SE6 to 12.2.46 or 12.2.5x or 15.0.x...the upgrade it's ok the swithc boot..and the configuraiton is same...
but the giga 0/1 and 0/2 on 2960 not bring up....and the better the interface on 3750 are up.....
If you have idea???
best regards

Hi,
Under interface gi0/1 and 0/2 did you do a "no sh"?
Can you post "sh int gi0/1 capa"?
What is the interface on the 3750 side?
Can you post configs?

Hi
Have you tried adding the following commnd to the port channel interface:
switchport trunk encapsulation dot1q
Some interface also require you to hard code speed and duplex, you can try these commands also.
You might also want to try removing all the other config from the interfaces and just keep the basic config to see if the interfaces and port channel comes up.
interface GigabitEthernet0/23
description xxxxxx
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
end
interface GigabitEthernet0/24
description xxxxxxxxx
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
end
interfaceface Port-channel1
description xxxxxxxxx
switchport trunk encapsulation dot1q
switchport mode trunk
end
Thereafter issue a 'show int status' to see if there are any error conditions for those interfaces like err-disable.
