Using 3rd Party vendor SFP for Cisco Switch

Cisco switches are configured to use only Cisco genuine SFP's (Small Factor Pluggable) were unlike GBIC's where you can use almost any 3rd party vendor GBIC (Like Nortel, Juniper etc.). In order to overcome this limitation use the following command:

Switch(config)#service unsupported-transceiver

The following message will appear:

Warning: When Cisco determines that a fault or defect can be traced to
the use of third-party transceivers installed by a customer or reseller,
then, at Cisco's discretion, Cisco may withhold support under warranty or
a Cisco support program. In the course of providing support for a Cisco
networking product Cisco may require that the end user install Cisco
transceivers if Cisco determines that removing third-party parts will
assist Cisco in diagnosing the cause of a support issue.

Then type the following command:

no errdisable detect cause gbic-invalid

After that you will be able to use almost any SFP from any vendor.


There might be some compatibility issues with one vendor or another but usually the main brands in the market will fit fine for both GBIC's and SFP's.
