RE: SFP module recommendation for 3560 switch

Are the ports going into "errdisable".

They have a mechanism that will put the port into "errdisable" when it
detects a GBIC or SFP that is from another vendor than Cisco.

 

There is a hidden command that will resolve this issue. See below.

 

Enables the use of third-party SFP or GBIC modules on Cisco switches but
note the warning below.

Example output:

Switch(config)#service unsupported-transceiver

 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.

Subject: SFP module recommendation for 3560 switch

Hi,

Looking for a recommendation on SFP modules compatible with Cisco 3560
switches to interconnect it to the GBIC on a 3550 switch. I tried a
Finisar
ftrj-8519-7 but it's not working with the Cisco 3550 GBIC (1000 base SX
850nm). I see lights on the TX side of the fiber on each GBIC but ports
show
down/down. Any recommendations for where to purchase or part numbers
are
appreciated.

Thanks,

Ian
