switchport

interface TwentyFiveGigE1/0/23
switchport
switchport trunk allowed vlan 99,110,111,120,130,140,150,160,170
switchport mode trunk
channel-group 13 mode active

Have you tried an alternative port and sfp just to make sure it snt a physical error?

The configs are wrong.
Look at each 9200 physical interface: It says "channel-group 11 mode active" but the port-channel is 14. Of course it won't work.
Look at the port channel configuration (both ends), where are the allowed VLANs?

shared configuration have some errors. You need to bind both interfaces on same port-channel. Please refer to below config for reference:

interface TenGigabitEthernet1/1/1
switchport mode trunk
channel-protocol lacp
channel-group 14 mode active
end

 

#show run int tenGigabitEthernet 1/1/2
