Forcing A Cisco Catalyst Switch To Use 3rd Party SFP Modules. Many companies are seeking for Cisco SFP alternatives to help cut down the costs on these expensive modules. A frequent customer problem with Cisco's new line of Catalyst switches is that they do not support 3rd party (non- Cisco) SFPs - or at least they do not seem to.. If you've just replaced your network switches and tried using any 3rd party SFPs to connect your network backbone, you'll quickly stumble across an error similar to the following: %PHY- 4- UNSUPPORTED!
Test your ability to configure basic settings on a cisco switch : console configuration, telnet access.

This lesson explains how to use PuTTY Terminal Emulator to configure, monitor or manage a Cisco Router or Switch.
This happens because Cisco Catalyst switches are configured by default not to work with non- Cisco SFPs. When a SFP is inserted into a switch's GBIC port, the switch immediately reads a number of values from the SFP and if it doesn't like what it sees, it throws the above error message and disables the port. All SFP modules contain a number of recorded values in their EEPROM and include: Vendor Name. Vendor IDSerial Number. Security Code. CRCHow To Force Your Cisco Switch to Use 3rd Party SFPs. Despite the error displayed, which leaves no hope for a solution, keep smiling as you're about to be given one.
There are two undocumented commands which can be used to force the Cisco Catalyst switch to enable the GBIC port and use the 3rd party SFP: 3. G- Stack(config)# service unsupported- transceiver. Warning: When Cisco determines that a fault or defect can be traced tothe use of third- party transceivers installed by a customer or reseller,then, at Cisco's discretion, Cisco may withhold support under warranty ora Cisco support program.
In the course of providing support for a Cisconetworking product Cisco may require that the end user install Ciscotransceivers if Cisco determines that removing third- party parts willassist Cisco in diagnosing the cause of a support issue. G- Stack(config)# no errdisable detect cause gbic- invalid.
When entering the service unsupported- transceiver command, the switch will automatically throw a warning message as a last hope to prevent the usage of a 3rd party SFP. The no errdisable detect cause gbic- invalid command will help ensure the GBIC port is not disabled when inserting an invalid GIBC.
Since the service unsupported- transceiver is undocumented, if you try searching for the command with the usual method (?), you won't find it: 3. G- Stack(config)# service ?

We tried both service unsupported- transceiver & no errdisable detect cause gbic- invalid commands on 2. G, 3. 56. 0G, 3. 75.
G, 4. 50. 7R and 4. R- E Catalyst switches and all accepted the commands without a problem. In fact if the Catalyst switch is running IOS 1. SE and above, the undocumented commands are available. Should 3rd Party SFPs Be Used?
There are mixed feelings about this. We certainly do not recommend using non- Cisco SFP's in production environments, however in a lab environment, its most probably a cheap way out. When using 3rd party GBICs, one must keep in mind that Cisco TAC will not provide any support for problems related to the SFPs as they are totally unsupported. Here is a small portion from the Cisco Catalyst 3. G Q& A that refers to the usage of 3rd party SFP modules on the switch: Q.
Do the Cisco Catalyst 3. Series Switches interoperate with SFPs from other vendors?
A. Yes, starting from 1. SE release, the user has the option via CLI to turn on the support for 3rd party SFPs. However, the Cisco TAC will not support such 3rd party SFPs.
In the event of any link error involving such 3rd party SFPs the customer will have to replace 3rd party SFPs with Cisco SFPs before any troubleshooting can be done by TAC. Back to Cisco Switches Section.
