Configuring Virtual Services

a system in another geographical location). To specify the server of last resort, use the
optional

server-last-resort

argument:

config server-group name policy

server-last-resort

After a server-group is created, add a server or range of servers to it using the following
commands:

config server-group name add-server index

config server-group name add-server ip-address

config server-group name add-server index

config server-group name add-server ip-address

You can specify a server or range of servers by IP address or by server index. For
example:

config server-group name group1 add-server index 1

config server-group name group1 add-server ip-address 10.10.10.2

config server-group name group1 add-server index 1 - 34

config server-group name group1 add-server

ip-address 10.10.10.2 - 10.10.10.15

To delete a server or range of servers from a group, use the following commands:

config server-group name delete-server index

config server-group name delete-server index -

config server-group name delete-server ip-address

config server-group name delete-server ip-address

This removes the specified server (or servers) from the server group, but leaves it
configured in the system, so that it can be added to a different group.
