config global-load-balance virtual-server-pool
Use this command to configure the virtual server pool. The virtual server pool configuration defines the set of virtual servers that can be matched in DNS resource records, so it should include, for example, all the virtual servers that can be responses for DNS requests to resolve www.example.com. You also specify the key parameters of the global load balancing algorithm, including proximity option, status checking options, load balancing method, and weight.
Before you begin:
• You must have created the global load balance server configuration and you must know the names of the virtual servers that have been populated in that configuration.
• You must have read-write permission for global load balancing settings.
After you have created a virtual server pool configuration object, you can specify it global load balancing host configuration.
Syntax
config global-load-balance virtual-server-pool
edit <name>
set check-server-status {enable|disable}
set check-virtual-server-existence {enable|disable}
set default-feedback-ip <class_ip>
set default-feedback-ip6 <class_ip>
set load-balance-method wrr
set proximity {GEO|GEO-ISP|NONE}
config member
edit <No.>
set backup {enable|disable}
set server <datasource>
set server-member-name <string>
set weight <integer>
next
end
next
end
check-server-status | Enable/disable polling of the local FortiADC SLB. If the server is unresponsive, its virtual servers are not selected for DNS answers. |
check-virtual-server-existence | Enable/disable checks on whether the status of the virtual servers in the virtual server list is known. Virtual servers with unknown status are not selected for DNS answers. |
default-feedback-ip | Specify an IP address to return in the DNS answer if no virtual servers are available. |
default-feedback-ip6 | Specify an IPv6 address to return in the DNS answer if no virtual servers are available. |
load-balance-method | Only weighted round-robin is supported. |
proximity | • None—Proximity not used. • GEO—Proximity based on geolocation. • GEO-ISP—Proximity based on IP address belonging to an ISP address group first, then geolocation. |
config member |
backup | Enable to designate the pool as a backup member of the group. All backup members are inactive until all main members are down. |
server | Specify a global server load balancing servers configuration object. |
server-member-name | Specify the name of the virtual server that is in the servers virtual server list configuration. |
weight | Assigns relative preference among members—higher values are more preferred and are assigned connections more frequently. The default is 1. The valid range is 1-255. |
