Nexus 3524 not recognizing SFPs?

[drkershner]

 Good morning all

The Cisco Nexus 3548 and 3524 have the following hardware configuration:

●      48 fixed Enhanced Small Form-Factor Pluggable (SFP+) ports (1 or 10 Gbps); the Cisco Nexus 3524 enables only 24 ports

 States in the documentation it accepts 1 or 10G SFPs. But when I put 10G RJ-45 SFPs I get "invalidXv" under status. I've tried different entries but still same issue.

  Does anyone know if this is a software upgrade or is it that it only accepts fiber 10G?

Software

NXOS: version 9.3(7)

 - Did you verify compatible SFP's for the particular device models according to : https://tmgmatrix.cisco.com/

OK, that chart seems to be all optics with a few electrical. I didn't see the RJ-45 10G listed and it is a cisco part (SFP-10G-T-X)

From the switch "show int status"

Eth1/2 -- invalidXv 1 auto auto SFP-10G-T-X

So it see's and recognizes the SFP

 - If you look at https://tmgmatrix.cisco.com/?npid=1121 (e.g.) ;  find  copper   , mentioned transceivers in left column will only go up to 1G , seems documentations is faulty ,

Might have recognised but as i read the docs does not work.

Still looking more tentative answer raise an TAC case.

10G RJ-45 SFPs  - is this cisco SFP ? what is the model and any picture.

When you insert the SFP in to switch, what logs you see on the console or show logging last 100

as per the information as of now only nexus 9K and NC support this :

Transceiver to host compatibility

Q.  Which Cisco platforms will support the SFP-10G-T-X transceiver?

A.  At the release, the Nexus 9000 and NCS 5501 platforms will support the transceiver. Please check the Cisco compatibility matrix for the latest information on platform support: https://tmgmatrix.cisco.com.

I opened a TAC case as the switch is supposed to be 48x10GE Supervisor

[balaji.bandi]

Sure we hear from you what TAC say about it.

[drkershner]

 According to Cisco TAC the N3K-3524P-10G-X will do 10G via fiber but not RJ-45. Even though the fiber SFP converts the laser to electrical to transit the switch. Even though there is a 10G RJ-45 SFP made by Cisco out there.

 What a load of donkey waste.
