Get information, set speed and duplex for ESX/ESXi physical NICs. The vicfg-nics command manages uplink adapters, that is, the Ethernet switches used by an ESX/ESXi host.
You can use vicfg-nics to list the VMkernel name for the uplink adapter, its PCI ID, driver, link state, speed, duplex setting, MAC address and a short PCI description of the card. You can also specify speed and duplex settings for an uplink adapter.
vicfg-nics --auto <nic>
vicfg-nics --duplex [full|half] <nic>
vicfg-nics --speed [10 | 100 | 1000 | 10000] <nic>
vicfg-nics --vihost <esx_host>]
|--auto | -a ||Sets the NIC to auto-negotiate its speed and duplex settings Requires a NIC parameter.|
|connection_options||Specifies the target server and authentication information if required. Run vicfg-nics --help for a list of all connection options.|
|--duplex | -d [full|half] ||Sets the duplex value at which a given network adapter should run to either full (transmit data in both directions at the same time) or half (transmit data in one direction at a time). Requires a NIC parameter.|
|--help||Prints a help message for each command-specific and each connection option. Calling the script with no arguments or with --help has the same effect.|
|--list | -l||Lists the NICs in the system and, for each NIC, the PCI bus, driver, speed, duplex information, MAC address, and a description. Also shows whether the link is up.|
|--speed | -s ||Sets the speed at which a given network adapter should run. Valid values for |
|--vihost | -h||When you run a vCLI command with the --server option pointing to a vCenter Server system, use --vihost to specify the ESX/ESXi host to run the command against.|
