[cisco-voip] OT -- Cisco or CXTec Gbics ??

[Tim Reimers]

This is the link I'd found which describes that possibility -

 

What I don't know is whether CXTec is different from other "Oriental"
(ahem) providers in that regard....

Use Third Party SFP Modules 

The use of third party SFP transceivers with Cisco devices is not
supported by Cisco. Cisco-approved SFP modules have a serial EEPROM that
contains the module serial number, the vendor name and ID, a unique
security code, and cyclic redundancy check (CRC). When an SFP module is
inserted in the switch, the switch software reads the EEPROM to verify
the serial number, vendor name and vendor ID, and recomputes the
security code and CRC. If the serial number, the vendor name or vendor
ID, the security code, or CRC is invalid, the software generates this
security error message and places the interface in an error-disabled
state:

SYS-3-TRANSCEIVER_NOTAPPROVED:Transceiver on port [dec]/[dec] is not
supported

I use mostly Cisco although I loved CXTec's products.  I got burned (I
believe it was CATOS) on a software upgrade where it somehow figured out
which were which and put my CXTec SFPs into shutdown and labeled them as
non approved.

Hi all -

 

What do you folks use for SFP modules??

 

We have a mix of Cisco and some CXTec, who claim to be using
Cisco-compatible SFPs that are

certified (in some way) not to be cheap manufacturing fakes..

 

 

 

thanks, Tim
