I am unable to set speed of a switch. I could see that the supported modes of port is 10000
cumulus@cumulus:~$ sudo ethtool xxx
Settings for swp8s3:
Supported ports: [ FIBRE ]
Supported link modes: 10000baseT/Full
Supported pause frame use: Symmetric Receive-only
Supports auto-negotiation: Yes
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Speed: 10000Mb/s
Duplex: Full
Port: FIBRE
PHYAD: 0
Transceiver: internal
Auto-negotiation: off
Link detected: yes
When I try to execute the command
ethtool -s swp8s2 speed 1000 duplex full
it throws error,
Cannot set new settings: Operation not supported
not setting speed
not setting duplex
Is it because its not in the "Supported link modes"?
Hi Nivas. Yes, that is correct. the supported speed interpreted for the module is 10,000 and you are trying to do 1,000.
It is possible to get 1G over a 4x10G breakout scenario, but it requires modules that support it and it may require a CL version change.
What is your use case and what module/cable do you have installed? Also what switch hardware and CL version are you running?
It may be a good idea to open a support case to sort out the particulars of your scenario.
