In 4.8 and later the command was deprecated.
Q. How are the 7050Q shared QSFP+ ports changed to the SFP+ ports?
A. By default the Arista 7050Q has the 8 SFP+ ports disabled, and they must be enabled before
being used. There is a hardware command to activate the SFP+ ports, and disable the associated
QSFP+ ports.
SFP+ Ports 17-20 are associated with QSFP+ port 15/1-4
SFP+ Ports 21-24 are associated with QSFP+ port 16/1-4
The command to configure the mode:
(config)#hardware port-group 1|2 select qsfp|sfp
To activate Eth17-24 you need:
(config)#hardware port-group 1 select Et15/1-4 | Et17-20
To activate Eth21-24 you need:
(config)#hardware port-group 2 select Et16/1-4 | Et21-24
Using this command will restart the forwarding agent, which will cause all links in these port groups
to flap. Proceed with caution if in a production environment.
Using the QSFP+ ports, with a transceiver for 4x10G mode requires the same command as for the
7050-64 switches to enable 4x10G mode on the uplinks.
