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
