$ esxcli network nic set -S 10000 -D full -n <iface>
This command sets the forced speed to 10 Gbps.
$ esxcli network nic set -a -n <iface>

$ esxcli network nic pauseParams list
Use this command to get Pause Parameters list.
$ esxcli network nic pauseParams set --auto <1/0> --rx <1/0> --tx <1/0> -n <iface>
Use this command to set Pause Parameters.
Note: For 10GBase-T NetXtreme-E network adapters, auto-negotiation must be enabled. Using
forced speed on 10GBase-T adapter results in esxcli command failure.
Note: VMWare does not support 25G speeds in ESX6.0. In this case, use the second utility
(BNXTNETCLI) to set 25G speed. For ESX6.0U2, the 25G speed is supported.
Note: Flow control/pause auto-negotiation can be set only when the interface is configured in link
speed auto-negotiation mode.
