Network interfaces
To display network interfaces and their assigned IP addresses and nameserver addresses, type the show interface
LYSH@MyHostName# show interface

Assigning the IP address
Both IPv4 and IPv6 addresses can be configured in the configuration mode.
LYSH@MyHostName# configure // Enters configuration mode. configure# ip add eth0 192.168.0.3/24 192.168.0.1 // Configures an IPv4 address, subnet, and gateway.(i.e. 192.168.0.1) configure# ip add eth0 2000:4::40/64 2000:4::1 // Configures an IPv6 address, prefix, and gateway.(i.e, 2000:4::1) interface setting was added. Do you want to apply these settings?(y/n): y // immediately apply the configurations. configure# exit configure# show interface LYSH@MyHostName# ping 192.168.0.1 LYSH@MyHostName# ping6 2000:4::1
Note that, If a network interface already has an assigned IP address and you configure another IP address and gateway of the same version, the gateway is ignored. In the words, the secondary gateway of the same version is not allowed.
Deleting the IP address
LYSH@MyHostName# configure // Enters configuration mode. configure# ip delete eth0 192.168.0.3/24 // Deletes an IPv4 address(i.e. 192.168.0.3/24) configure# ip delete eth0 2000:4::40/64 // Deletes an IPv6 address(i.e. 2000:4::40/64) interface setting was deleted. Do you want to apply these settings?(y/n): y // immediately apply the configurations. configure# exit configure# show interface
Note that, If a network interface has multiple assigned IP addresses of the same version(i.e. IPv4 or IPv6), the gateway address is not removing before deleting all IP addresses of the same version from a network interface.
