[admin@jetcom-test] > ip address add address=202.47.77.247 netmask=255.255.255.240 interface=ether1
[admin@jetcom-test] > ip address print
Flags: X – disabled, I – invalid, D – dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0 202.47.77.247/28 202.47.77.240 202.47.77.255 ether1
1 192.168.0.1/24 192.168.0.0 192.168.0.255 ether2

untuk IP public “202.47.77.247” di tempatkan di ethernet 1
untuk Ip Private “192.168.0.1” di tempatkan di ethernet 2

[admin@jetcom-test] > ip dns set primary-dns=202.47.78.8/9
[admin@jetcom-test] > ip dns print
primary-dns: 202.47.78.8
secondary-dns: 202.47.78.9
