what's the command to find out switch interface transceiver/cable?

Unanswered Question
Jun 28th, 2009

I need to do a remote network audit for a customer's switch environment(65xx/45xx/37xx/35xx/29xx) to find out what kind of transceiver(GBIC/SFP) and cable(fiber/copper) are connected to each interface of the switch. Is there such a command to do it? Thanks for any help!

I have this problem too.

it seems this command can show the transceiver's type, however is it possible to find out what kind of fiber(for example Multimode OM1, OM2, OM3, 50 or 62 micron?) is connected to the interface?

Unfortunately AFAIK there is no such quick fix.

I use sometimes "sh interface transceiver detail". It is available on some platforms only and requires DOM to be enabled.

It gives the laser budget amongs other things. Whether db thershold can be mapped to Fiber type ...I dont know.

I hope the show interface status will give u the desired output.

Depending on your IOS, the sh inventory, was introduced on the 12.2 EA5 IOS starting with the 2950/3550 until present.

This command would give a user a comprehensive view of various items in your switch, particularly modules, blades, GBICs, etc.

Hope this helps.
