X2-10GB-SR to SFP-10G-SR-S= Compatibility ?

[jeremytetart]

Hello Guys,

I have two question for you in order to be sure I'm not wrong.

###First question###

I have to connect two switch between them.

- Nexus 6000 with a SFP (SFP-10G-SR-S)

to

- Catalyst C4510R-E with a SFP (X2-10GB-SR), supervisor (WS-X45-SUP6-E).

I have checked the datasheet of 2 SFP and for me they are compatible. Someone can confirm me that's true ?

Here the datasheet => http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/10-gigabit-modules/product_data_sheet0900aecd801f92aa.html

Here the datasheet => http://www.cisco.com/c/en/us/products/collateral/interfaces-modules/transceiver-modules/datasheet-c78-733585.html

###Second question###

In the datasheet (link in below), the supervisor module WS-X45-SUP6-E require the Minimum Software Release 12.2(54)SG for Dom support.

http://www.cisco.com/c/en/us/td/docs/interfaces_modules/transceiver_modules/compatibility/matrix/10GE_Tx_Matrix.html#_Toc478656477

Which command sould I launch to check the DOM version on my switch ? I did'nt find anything on web.

Thank in advance for your help.

Regards.

Hi,

The optics look correct. You would need a LC to SC fiber patch to connect the 6000 to the 4500.

As for your second question, DOM is for monitoring the optics and you can do that by issuing "sh interfaces transceiver" 

here is more info

BTW, the command suggested in this link does not seem to be supported any more.

Reza Sharifi & absmythe1,

Thank you for your answers ;-)

Yes, the optics are compatible. The only difference is that S class optics don't support FCoE.
