Use ip and ss Commands

Use the ip and ss commands to view a list of network interfaces and information for IP addresses.

Although the ifconfig command and the netstat command work on Photon OS, VMware recommends that you use the ip or ss commands. The ipconfig and netstat commands are deprecated.

For example, to display a list of network interfaces, run the ss command instead of netstat. To display information for IP addresses, run the ip addr command instead of ifconfig -a.

Examples are as follows:

USE THIS IPROUTE COMMAND     INSTEAD OF THIS NET-TOOL COMMAND
ip addr                     ifconfig -a
ss                             netstat
ip route                     route
ip maddr                     netstat -g
ip link set eth0 up         ifconfig eth0 up
ip -s neigh                    arp -v
ip link set eth0 mtu 9000    ifconfig eth0 mtu 9000

Using the ip route version of a command instead of the net-tools version often provides more complete and accurate information on Photon OS. Examples are as follows:

ip neigh
198.51.100.2 dev eth0 lladdr 00:50:56:e2:02:0f STALE
198.51.100.254 dev eth0 lladdr 00:50:56:e7:13:d9 STALE
198.51.100.1 dev eth0 lladdr 00:50:56:c0:00:08 DELAY

arp -a
