3750 GLC-GE-100FX

[darenn]

Hi,

We are currently migrating our network using 3750's and have a laser link between two buildings with MMF at each site.

They are currently using Allied Telesyn AT-FS202 100Base-FX Media Convertors at either end running at

100/Full duplex.

As a test we have connected a couple of C3750-48TS together using GLC-GE-100FX SFP's and we are noticing half duplex on the test link. Is this normal operation for these SFP's ? It takes the link

down if you hardcode the interface to full duplex.

Regards

Daren
