How can I enable the SFP+ ports on a Q16?

The ports are by default in errdisable state, but when I set the speed to auto, they show as Status – unknown, Duplex – auto, Speed – auto. ‘show int eth xx‘ phy shows no status in the PMA/PMD as shown below:

localhost#sh int eth21-22 phy
    U    = Link up
    D    = Link down
    R    = RX Fault
    T    = TX Fault
    B    = High BER
    L    = No Block Lock
    A    = No XAUI Lane Alignment
    0123 = No XAUI lane sync in lane N
                                  State    Reset
 Port           PHY state        Changes    Count PMA/PMD PCS   XAUI
 -------------- --------------- -------- -------- ------- ----- --------
 Ethernet21     unknown                0        0               D..A0123
 Ethernet22     unknown                0        0               D..A0123

Any ideas anyone?

Hi Mohan,

Please see the section on the ’hardware port-group’ command in EOS-4.13.6F manual – you can download that from Arista support website.

The specific command required in your case seems to be:

(config)# hardware port-group 2 select Et21-24

Let us know if you have any further questions.
