network

The network command displays Ethernet interfaces or runs external loop-back tests. If the ifs option is used, the command displays a list of Ethernet ports that are available for external loop-back tests.


Note -  Ports need to be configured with IP addresses prior to running this command. You can use the EFI Shell application ifconfig to configure IP addresses. Enter the udiag network ifs command to verify that all Ethernet ports are configured correctly.

With two interface numbers specified, this command tests the ports by sending packets from the first port and by receiving and verifying the packets from the second port.
