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!

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.
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)

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?

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
