[c-nsp] WS-X6904-40G + FourX: Some SPF+ cause err-disable

[Chris Welti]

Hi Matti,

What type of SFP+ do you use?
"show idprom int Te4/13 | i Product"

the "service unsupported-tranceiver" only helps with the "vendor protection", but
not with the transceiver type (Product ID).
E.g. the FourX adapter supports the following SFP+ types:

SFP-H10GB-CU1M
SFP-H10GB-CU3M
SFP-H10GB-CU5M
SFP-10G-SR
SFP-10G-LRM
SFP-10G-LR
SFP-10G-ER
DWDM SFP+

see: http://www.cisco.com/c/en/us/td/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6974.html

If you have anything else, e.g. SFP-10G-ZR, 10G CWDM, 10G Bi-Dir, etc it will not work no matter what. Even with
Cisco original plugins.
The only possibility/workaround then is to reprogramm the SFP+ EEPROM to specify another type, e.g. SFP-10G-ER.
(or convince Cisco to update its allowed tranceiver type in the next IOS version :)

Cheers,
Chris
