CVR-X2 module won't recognize SFP-10G-LR module in 6506E 8port 10GE blade

[MARK CHRISTY]

I have a core infrastructure network built on the 6506E chassis. I have the CEF720 8 port 10GE with DFC blades (WS-X6708-10GE). I have purchased 4 CVR-X2-SFP10G (V03) modules, and 2 of each of the SR and LR SFPs for them. What is happening is that any of the CVR-X2 modules with the SFP-10G-LR sfp inserted is not recognized (expample next shows an OK SR sfp, followed by an LR sfp):

Port         Name               Status       Vlan       Duplex  Speed Type

Te1/1/7      SFP-10G-SR Mod     notconnect   5            full    10G 10Gbase-SR

But none of the SFP-10G-LR modules are recognized whether in the same port or blade:

Port         Name               Status       Vlan       Duplex  Speed Type

Te1/2/7      SFP-10G-LR Mod     notconnect   1            full    10G unknown

I cannot find any "bug" on my CCO web. A local Cisco Gold partner says that all should work together. Cisco's web site and data sheets all say it's AOK. This is not looking good. Without the LR modules, These same blades have older CVR-X2 modules with both SR, LR and Copper 10GB sfps installed and working.

What could be going on here?

Hi Mark,

According to this link:-

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750e_3560e/hardware/install/notes/1757202.html

Table 3

Table 3 Supported SFP+ Modules and Patch Cords 

SFP+ Module Number	Description
SFP-10G-SR	Cisco 10GBASE-SR SFP-Plus transceiver module for MMF, 850-nm wavelength
SFP-H10GB-CU1M	Twinax cable assembly, 1m, 30 AWG
SFP-H10GB-CU3M	Twinax cable assembly, 3m, 30 AWG
SFP-H10GB-CU5M	Twinax cable assembly, 5m, 24 AWG

The CVR-X2 only supports the SR version of the SFP+

Alex,

I think you found the problem. I also found more detail showing that possibly I would need to upgrade my IOS from....

My current IOS: 12.2(33)SXI11(fc2) (s72033_rp-IPSERVICESK9_WAN-M)

Update to IOS:  12.2(33)SXJ1

I think that's a newer IOS (because SXJ... comes after SXI...).

Heres the link I found this at, way down the page under Catalyst 6xxx...

http://www.cisco.com/c/en/us/td/docs/interfaces_modules/transceiver_modules/compatibility/matrix/10GE_Tx_Matrix.html

Since I didn't mention I have a 6506E - I looked further, but it still appears to be a true statement.

What do you think?
