SG200 SFP Compatibility

[damian.woz]

Hello,

We want to connect SG200 to Catalyst 2960X via optical fibre. Now on our SG200 (SG200-50P-K9-EU) switches are using D-Link DEM-311GT SFP modules.

We found module Cisco GLC-SX-MMD, that is compatible with Catalyst series switches, but there's no info about Small Business series. Someone has tried to run this module on Cisco SB?

Hello,

SG200 series support these SFP:

To interconnect a Small Business switch with Cisco Catalyst switch, you need to use Cisco Small Business SFP on the Small Business switches, and Cisco traditional SFP on Catalyst switches. And the SFP on both sides should follow the same IEEE standard. The mapping table is shown below.

Cisco Small Business SFP	Cisco traditional SFP
GE Transceiver
MGBSX1	GLC-SX-MM SFP-GE-S
MGBLX1 MGBLH1	GLC-LH-SM
MGBBX1	GLC-BX-D
MGBT1	GLC-T SFP-GE-T
FE Transceiver
MFEFX1	GLC-FE-100FX GLC-GE-100FX
MFELX1	GLC-FE-100LX
MFEBX1	GLC-FE-100BX-D

Thanks.

I tested Cisco GLC-SX-MM in a SG200, it works fine. Not officially supported, but gives no problems. And it saves having to buy the officially supported SFP's!

Very helpfull info

[Stojan Savic]

Just an update for anyone encountering this scenario -

Regarding the Cisco Start portfolio - Check out Page 27 of the Catalog (Click here)(pdf attached for convenience). This is the Nov 2017 catalog.

Though the GLC-LH-SMD transceiver shows as supported (Likely due to the EoS of MGBLX1).

The GLC-SX-MMD does not show up as confirmed compatible.

I've not tested the scenario myself as there are a few switch series within the Cisco Start portfolio, but as per Richard's response and the example you give of DEM-311GT working - It looks likely that you'll detect the GLC-SX-MMD in that series. But as per the link, nothing official.

Also I'd recommend checking out Salesconnect (click here). Plenty useful resources available.

Hope the info helps!
