The following table describes the Virtual IP Addressing configuration settings.

Option

Description

 

 

Virtual IP on/off

Enables or disables virtual IP addressing.

 

If virtual IP addressing is disabled, appliance nodes cannot

 

cover each other’s failures.

 

 

Edit virtual IP

Allows you to edit your list of virtual IP addresses. Changes

addresses

will not be effective until you click the Restart button on the

 

same page.

 

Incorrect IP addressing can effectively disable your system.

 

Make sure you understand how virtual IP addresses work

 

before you change them. If you do not assign a range of

 

valid virtual IP addresses to the appliance’s manager

 

process, nodes cannot cover each other’s failures.

 

 

Adding entries to the Virtual IP address list

You can add or change entries in the Virtual IP address pool by modifying the appliance’s Virtual IP address list.

Modifying the Virtual IP address list

1 On the Server Basics page, scroll to the Virtual IP Addressing section.

2Click the Edit virtual IP addresses link.

The Virtual IP page appears. You can add, remove, or modify Virtual IP addresses by clicking the Add Entry, Delete, or Modify buttons.

Adding a Virtual IP address

1Click the Add Entry button in the Virtual IP page.

2In the IP Address field, enter the virtual IP address.

3In the Device field, enter the network interface name (for example, iprb0).

4In the Subinterface field, enter the subinterface-ID.

This is the number between 1-255 that the interface uses for the address.

5Click the Add button.

Note

To reset the fields, click the Reset button.

Handling

If you have multiple network interfaces, the appliance monitors the state of the

multiple

interfaces and detects failure. It does this by sending ICMP echo requests, much

interfaces

like the ping command.
