SFP modules can not be found on show int trans

[Yohei.Nakano]

I purchased new N2K-C2348TQ, SFP-10G-SR and CVR-QSFP-SFP10G for additional ports.
All the QSFP ports are already in use, so there is no choise to use the converter module for inter connection of N2K and N5K.

The combination works properly, but I cannot check the serial number by "show int trans".
it says;

Fabric Port: Ethernet1/43
Fex Uplink: 9
    sfp is not supported
    sfp is present but not supported
    Invalid calibration

Fabric Port: --
Fex Uplink: 10
    sfp is not supported
    sfp is present but not supported
    Invalid calibration

Fabric Port: --
Fex Uplink: 11
    sfp is not supported
    sfp is present but not supported
    Invalid calibration

Fabric Port: --
Fex Uplink: 12
    sfp is not supported
    sfp is present but not supported
    Invalid calibration

Does anyone know show command to find out the serial number?

Hi

These are Cisco branded SFPs yes , if there no cisco but work that's may be why there showing unsupported

Ethernet1/19
    transceiver is present
    type is 10Gbase-SR
    name is CISCO-FINISAR
    part number is FTLX85...........................

try this command works on my 5ks as above output

sh int transceiver fex-fabric details

Thank you for the comment.

I tested the show command but could not get serial numbers.
The result was as follows;

N5K# sh int transceiver fex-fabric details
Ethernet1/11
    transceiver is not present

    Calibration/Detail information unavailable

Ethernet1/12
    transceiver is not present

    Calibration/Detail information unavailable

Firstly I thought this was because of 40g-2-10g converter.
But I noted that QSFP-H40G-ACU7M=, short copper qsfp cable, was also not detected on FEX-fabric side port.
Maybe parent Nexus5K cannnot detect SFP modules on fex-fabric side.

"show inventory" should do
