Here is our UCS running 2.0 and I am able to set the FC uplink speed

ucsfi-01-A /fc-uplink/fabric/port-channel # show detail

Port Channel:
    Port Channel Id: 255
    Name: ucs-n5k-pc255
    Admin State: Enabled
    Oper State: Up
    Admin Speed: Auto
    Oper Speed (Gbps): 32

ucsfi-01-A /fc-uplink/fabric/port-channel # set adminspeed
  1gbps  1 Gbps
  2gbps  2 Gbps
  4gbps  4 Gbps
  8gbps  8 Gbps

Hello Samuel,

Is this Ethernet uplink port or FC port ?

Hi there padramas, twe are using FC for uplinks.

If port is Ethernet uplink port, you can set the speed at 1/10/20/40 Gbps

If port is FC uplink port, I think that you cannot change the speed.

To my knowledge, you can configure FC uplink port's speed in a similar way, as you would for Ethernet uplink. However, the speeds options do not consist of 4 GIG option in 2.0 codes.

UCS-A# scope eth-storage
UCS-A /eth-storage # scope fabric a
UCS-A /eth-storage/fabric # create interface 1 33UCS-A /eth-storage/fabric/port-channel* # set adminspeed 

10gbps  10 Gbps

  1gbps   1 Gbps

  20gbps  20 Gbps

  40gbps  40 Gbps

Hello,

Yes, we can hard code speed for FC port channels but I need to check if we hard code speed for individual FC uplink port.

Will post it here once I read about this behavior.

As far as I know you can, I am unable to test it myself but have done so in the past without problem.
