Hello,
I meet a problem with a fiber optic link on my Cisco 2960-XR. I think the optical fiber is broken but i'm not sure...
The person who deployed optical fiber tells me that it works.
However, when I plug my fiber modules and fiber optics, my ports are: down down (not connected).
I made a mistake in my configuration?
int te1/0/1
switchport mode trunk
switchport nonegotiate
UDLD aggressive harbor
channel-group 10 mode active
cdp enable
switchport trunk allowed vlan 1-200
int te2/0/1
switchport mode trunk
switchport nonegotiate
UDLD aggressive harbor
channel-group 10 mode active
cdp enable
switchport trunk allowed vlan 1-200
interface Port-channel10
switchport mode trunk
switchport nonegotiate
Regards.

Post the output to the commands:
1. sh interface trunk;
2. sh interface Te 2/0/1;
3. sh interface Te 1/0/1
Your interface Po110 is missing this line: switchport trunk allowed vlan 1-200

Hi,
If the ports are down down (not connected), you have physical layer issue.
What is the output of
sh ip int brief te1/0/1
and
sh ip int brief te2/0/1
This command will give you the status of the ports.
