Gigabit transceivers -

Take a look at the transceiver in the link below.

http://www.cisco.com/en/US/products/hw/modules/ps5455/products_data_sheet0900aecd8033f885.html

I have a hard time believing no show commands can be executed to see if and where in a module these transceivers are connected.

I could understand if a serial number for the transciever doesn't show but surely a show command would indicate the presence of one.

Hi Rob

I'm not sure if this works for SFP transceivers but it does for GBICs.

You can see some info about transceivers installed in a module, i.e:

sh int giga3/16

GigabitEthernet3/16 is administratively down, line protocol is down (disabled)

Hardware is C6k 1000Mb 802.3, address is ....

...

Keepalive set (10 sec)

Full-duplex, 1000Mb/s, media type is LH...

If no transceiver is present the "media type is LH" information is not shown

Also you can use:

sh int giga3/16 cap

GigabitEthernet3/16

Model: WS-X6516-GBIC

Type: 1000BaseLH

Speed: 1000

Duplex: full

Trunk encap. type: ....

Here you can also see type.

If you are looking for another kind of information you could check this:

Re: Gigabit transceivers -

Good question.

Unfortunately I'm not aware of the relevant command.

You can do a quick check on types installed by doing

sh int | i SX or sh int | i LX

but this doesn't show the associated interface.

Only way I know is to look at each interface

sh int gigx/x
