Using third-party SFP modules in Cisco switches

Suppose we connected a third-party module to the first SFP port, we’ll look at the information about it:

show idprom int GigabitEthernet 1/1

In my case, on the Cisco Catalyst 6509-E, very many ports with third-party SFP modules after some time they turned off and in the logs information was written that the module was not supported.

Now go into the configuration mode:

config t

And we will make sure that the interfaces are not disabled when third-party SFP modules are enabled by entering the following commands:

service unsupported-transceiver
no errdisable detect cause sfp-config-mismatch
no errdisable detect cause gbic-invalid

After that, everything worked well.
