ESXi5 Command Line Reference - Networking Part1

This post is for the VMware administrators who started working in vSphere5 editions from vSphere 4 because ESX4 commands to configure networking is “esxcfg-” but esxi5 networking is configured with esxcli commands. Lets discuss about the detailed steps of configuring network using esxcli command.Since esxcli network has multiple sub commands under each commands. To get clear understanding of networking commands, I have posted each network sub commands under different post in different parts. This post is cover all options under esxcli network IP commands and its sub commands.

Esxcli networking commands starts with esxcli network and it gives all the options available under network options

~ # esxcli network

Lets discuss about the detailed steps under networking options

Esxcli network IP

~ # esxcli network ip

1.To get Global IP settings

1.1 To check IPv6 status

~ # esxcli network ip get
IPv6Enabled: false

1.2 To Set IPv6 enable

~ # esxcli network ip set -e true (reboot is required)

1.3 To set IPv6 disable

~ # esxcli network ip set -e false (reboot is required)

2.To Configure DNS settings

~ # esxcli network ip dns

~ # esxcli network ip dns search

2.1 To List the search domains currently configured on ESXi host

~ # esxcli network ip dns search list
DNSSearch Domains: lab.com

2.2 To add the domain to the list of domains to be searched when trying to resolve an host name on the ESXi host

~ # esxcli network ip dns search add -d vmwarearena.com
~ # esxcli network ip dns search list
DNSSearch Domains: lab.com, vmwarearena.com

2.3 To remove search domains from the list of domains to be searched when trying to resolve an host name on the ESXi host.

~ # esxcli network ip dns search remove -d vmwarearena.com
~ # esxcli network ip dns search list
DNSSearch Domains: lab.com

~ # esxcli network ip dns server

2.4 To Print the list of the DNS server currently configured on the ESXi server

~ # esxcli network ip dns server list
DNSServers: 192.168.0.20

2.5 To Add a new DNS server to the end of the list of DNS servers to use for this ESXi host.

~ # esxcli network ip dns server add -s 192.168.0.21
~ # esxcli network ip dns server list
DNSServers: 192.168.0.20, 192.168.0.21

2.6 To Remove a DNS server from the list of DNS servers to use for this ESXi host.

~ # esxcli network ip dns server remove -s 192.168.0.21
~ # esxcli network ip dns server list
DNSServers: 192.168.0.20

3.To Configure IP interface Settings

~ # esxcli network ip interface

3.1 To List the VMkernel network interfaces

~ # esxcli network ip interface list
vmk0
Name: vmk0
MAC Address: 00:0c:29:b6:a8:41
Enabled: true
Portset: vSwitch0
Portgroup: Management Network
VDS Name: N/A
VDS Port: N/A
VDS Connection: -1
MTU: 1500
TSO MSS: 65535
Port ID: 16777219

3.2 To add a new VMkernel network interface

To add a new vmkernel network interface, we need an existing port group. Creating port group will cover in my later part, For this example, we have an existing port group created called “VMOTION”

~ # esxcli network vswitch standard portgroup add -v vSwitch0 -p VMOTION

Now add the VMkernel network interface

~ # esxcli network ip interface add -i vmk1 -p VMOTION
~ #

3.3 To assign the IP address to the newly added vmkernel interface VMk1 using the below command

~ # esxcli network ip interface ipv4

# esxcli network ip interface ipv4 get

Name IPv4 Address IPv4 Netmask IPv4 Broadcast Address Type DHCP DNS
—- ———— ————- ————– ———— ——– ——————
vmk0 192.168.0.77 255.255.255.0 192.168.0.255 STATIC false

~ # esxcli network ip interface ipv4 set -i vmk1

~ # esxcli network ip interface ipv4 set -i vmk1 -I 192.168.0.78 -N 255.255.255.0 -t static
~ # esxcli network ip interface ipv4 get
Name IPv4 Address IPv4 Netmask IPv4 Broadcast Address Type DHCP DNS
—- ———— ————- ————– ———— ——–
vmk0 192.168.0.77 255.255.255.0 192.168.0.255 STATIC false
vmk1 192.168.0.78 255.255.255.0 192.168.0.255 STATIC false
~ #

3.4 To set the enabled status and MTU size of a VMkernel Interface of ESXi host

~ # esxcli network ip interface set -e true -i vmk1 -m 1500
~ #

3.5 To Remove a new VMkernel network interface from the ESXi host.

~ # esxcli network ip interface remove -i vmk1
~ #

After removal , We can only see only one vmkernel interface in the below list.

~ # esxcli network ip interface ipv4 get
Name IPv4 Address IPv4 Netmask IPv4 Broadcast Address Type DHCP DNS
—- ———— ————- ————– ———— ——–
vmk0 192.168.0.77 255.255.255.0 192.168.0.255 STATIC false

3.6 To list active TCP/IP Connections in ESXi host

~ # esxcli network ip connection

~ # esxcli network ip connection list
Proto Recv Q Send Q Local Address Foreign Address State World ID World Name
