load-balance create vip-range-name

Purpose

Creates a group of servers for load balancing.

Format

load-balance create vip-range-name <range name> vip-range <range> virtual-port <port

number> protocol tcp|udp [persistence-level]

Mode

Configure

Description

The load-balance create vip-range-name command lets you specify a range of “virtual”

IP addresses and a port number that is used by a client to access a server in the virtual IP

address range. You must also specify the protocol (for example, TCP for HTTP and FTP

sessions) to be used by the load balancing servers.

This command implicitly creates separate server groups for each virtual IP address in the

specified range. The <range name> you specify becomes the base group name. Thus, the

command load-balance create vip-range-name myrange vip-range 207.135.89.1-

207.135.89.15 virtual-port 80 protocol tcp creates the groups ‘myrange1’ with virtual IP

address 207.135.89.1, ‘myrange2’ with virtual IP address 207.135.89.2, etc. This command

allows you to create multiple server groups, each with unique virtual IP addresses,

whereas the load-balance create group-name command allows you to only create a single

group with a single virtual IP address.

After you create groups with this command, you can use the load-balance add host-to-

group command to identify specific server systems in each group. Or, you can use the

load-balance add host-to-vip-range command to add a range of server IP addresses to

each group.

Parameters

The base group name for this range of load balancing servers.
