Compatibility Cisco 3750 and GBIC 1000Base-ZX/SFP

[benoit.chassefeyre]

Hello,

I have some problems to use a GBIC 1000Base-ZX on a cisco 3750.

With some research , i have find these thing :

The Catalyst 3750 models support these Cisco SFP options:

1000BASE-LX

1000BASE-SX

1000BASE-T

1000Base-ZX didn't appear.

What do you think of such thing.

Thanks for help

The 1000BASE-ZX SFP (Cisco product number GLC-ZX-SM=) is supported on the Catalyst 3750:

Cisco Optical SFP Transceiver Compatibility Matrix

List price in the US is the same as for the 1000BASE-ZX GBIC (Cisco product number WS-G5487=)

It's possible that the information you have found has not been updated yet. I believe the ZX SFPs were among the last ones to become available. The Release Notes in the link below are the first ones to mention this SFP, they refer to it as "new hardware" (versus the SX and LX SFPs):

Hope this helps.
