Hello Mohamad,

try the following:

config term

int gi0/23

media-type sfp

to tell the switch you want to use the fiber based module and not the rj45

Hope to help

Hello Mohamad,

try also

conf t

int gi0/23

shut

no shut

the config guide lists only 100 Base X SFP

see

http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/12.2_46_se/configuration/guide/swint.html#wp1028628

So I wonder if it supports a real GE fiber based port

It is supported starting from release 12.2(25)FX

see table 4 in the following

http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6981.html#wp128965

Hope to help

Is the GLC-SX-MM from Cisco or is it from a third-party?

Is Interface Gig0/23 in error disable?

Is Interface Gig0/23 also being used by a copper line?

Have you tried to put this SFP somewhere else?

Have you tried other SFP?
