Catalyst 2960 - SFP issue (WS-C2960-24TC-L with GLC-FE-100FX)

[thiborba]

Hi Team,

I am trying to connect between 2 switches on Fiber.

Switch 1 - WS-C2960-24TC-L

Switch 2 - WS-C2955C-12

On 2955 side I have the fiber with MT-RJ Connector and LC connector on 2960 side.

For 2960 side I have two models of SFP (GLC-FE-100FX and GLC-SX-MM), I intend to use the GLC-FE-100FX, but even before connecting the fiber, I'm just installing the SFP, and the port is err disabling.

Can use one of these SFPs to connect these switches?

First, I just want to make SFP works on 2960 side...after connect the Fiber already connected on 2955 side.

on 2955 side fiber port config are:

interface FastEthernet0/13
description 100FX
switchport mode access
service-policy input gigcst
storm-control broadcast level 1.00 0.90
storm-control action trap

on 2960 side I put these configurations:

interface GigabitEthernet0/1
description 100FX
switchport mode access
storm-control broadcast level 1.00 0.90
storm-control action trap
service-policy input gigcst

Need your input please.

regards

Thiago

Looks like a compatible issue with 2955 check the matrix EXCEL attached both.

I believe 2960 should work - can you post the complete log of the message and show interface gig0/1 (output)

When the port goes into error-disable, post the complete output to the command "sh interface status err".
