Optical fiber & 2960-XR.

[irichaoli]

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.
