idprom command Cisco catalyst 3700 series

[JavaJunkie]

Hello I have a older 3750 and I am trying to determine exactly which SFP's are installed.  When I run a show idprom on a specific interface all I get are hex characters.  Examples below:

Identifier    :  0x03

Connector:   0x07

Is there a way to decipher what these values are?

Thank you!

Hi,

Try:

sh interfaces gi x/x/x capabilities

For "Type" I get "unsupported" on some of the interfaces.  Others show 1000BaseLX SFP in the Type field.

In general LX is single mode and SX is multimode?

I was hoping to find a command that told me specifically if the interface is single or multi-mode.

Thank you

That is exactly right. They don't always spell it out completely but SX is for Short haul (Multi-mode) and LX is Long haul (Single-mode)

And one more thing. If you do a show inter x/x/x you see something like this

media type is SFP-10GBase-SR, which means multi-mode
