SFP module not showing up as interface choice

I am trying to configure a 3825 router w/IOS 12.4(3d).

When I install a GLC-SX-MM module, I cannot see the module in the sh diag results and therefore not a choice in the list of interfaces.

When I view the logs, the insertion is logged.

Any assistance would be greatly appreciated,



Re: SFP module not showing up as interface choice

Sounds like a code or feature set problem . i would check to see what code you need to support this module. Code level looks high enough but may not be correct feature set , also need at least 256 meg of dram to support this card in your router...

Re: SFP module not showing up as interface choice

Hi Chris,

There are two Gigabit Ethernet ports on Cisco 3800 Series systems. Port 1 is a fixed 10/100/1000BASE-T RJ-45. Port 0 can choose between 10/100/1000BASE-T RJ-45 and an SFP module slot. SFP modules are optional.

A new command-line interface (CLI) allows you to choose between the two media types. The "SFP" option will only come up if there is a SFP module plugged into the slot. RJ-45 is the default.

Please see the following configurations to get this port working:

Cisco3825#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Cisco3825(config)#interface gigabitEthernet 0/0

Cisco3825(config-if)#media-type ?

rj45 Use RJ45 connector

sfp Use SFP connector

Cisco3825(config-if)#media-type sfp

After this you should be able to use and see the SFP on the router. Hope this helps. :)
