From ESX 4.0 Update 2, a new command-line network configuration tool called console-setup. It helps to simplify the process of creating or restoring networking in the ESX service console. It is recommended to use Physical console of the server via ILO or DRAC instead of using SSH to configure the network. Editing network configuration via SSH might cause a session disconnection and makes server not reachable via network.This Console-setup tool is completely menu driven. It will be more helpful for the administrators who hates to type commands to change the network configuration. It’s easy, just press numbers to perform your tasks. Let’s take a detailed look at it. Below the snapshot for console-setup tool with the basic options

1. Show Current vswif
2. Show Network Adapters
3. Show vSwitch/vDS Information
4. Delete vswif
5. Configure Service Console Network Interface
6. Exit

We will look at the each 5 options step by step by pressing numbers as instructed in the above snap.

Press 1 to show current service console network (vswif). The below snapshot shows that I have 2 console networks (vswif0 & vswif1)  along with its IP address and subnet mask

Press 2 to show the list of network adapters in my ESX host along with its  name,speed,MAC address and MTU.

Press 3 to show the list and information of vSwitch and port group along the physical adapter association information of that ESX host. My ESX server has 3 virtual switches (vSwitch0, vSwitch1 & vSwitch2) with 5 port groups.

Press 4 to delete the virtual switch from the ESX host. I have 2 service console network (vswif0 & vswif1). Let’s delete vswif1 for demo.

Enter 1 to delete the vswif1 and type “yes” to delete the vswif1. Now Vswif1 is deleted. Let’s confirm from the command line. Now we have only one vswif called “vswif0” after the deletion.

Press 5 to configure Service Console Network Interface.

For Demo, Let’s create a vswif interface named vswif1 with the following settings 
Port Group = Service Console 1
virtual switch = vswitch1
IP Address = 192.168.242.51
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.242.0
Physical Adapter =  vmnic1

Since It is the Long steps, I cannot the below step in the Screenshot. So Copied the commands.

Enter your choice (1-6): 5

5.2 Name of service port group [Service Console]
