Parameter Choices/Defaults Comments
alternate_lb_method
    Choices:
  • round-robin
  • return-to-dns

  • static-persistence
  • global-availability
  • virtual-server-capacity
  • packet-rate
  • drop-packet
  • fallback-ip
  • virtual-server-score
The load balancing mode that the system tries if the preferred_lb_method is unsuccessful in picking a pool.
availability_requirements
(added in 2.6)
Specifies, if you activate more than one health monitor, the number of health monitors that must receive successful responses in order for the link to be considered available.
type
    Choices:
  • all
  • at_least
  • require
Monitor rule type when monitors is specified.
When creating a new pool, if this value is not specified, the default of 'all' will be used.
at_least
Specifies the minimum number of active health monitors that must be successful before the link is considered up.
This parameter is only relevant when a type of at_least is used.
This parameter will be ignored if a type of either all or require is used.
number_of_probers
Specifies the number of probers that should be used when running probes.
When creating a new virtual server, if this parameter is specified, then the number_of_probes parameter must also be specified.
The value of this parameter should always be higher than, or equal to, the value of number_of_probers.
This parameter is only relevant when a type of require is used.
This parameter will be ignored if a type of either all or at_least is used.
number_of_probes
Specifies the minimum number of probes that must succeed for this server to be declared up.
When creating a new virtual server, if this parameter is specified, then the number_of_probers parameter must also be specified.
The value of this parameter should always be lower than, or equal to, the value of number_of_probers.
This parameter is only relevant when a type of require is used.
This parameter will be ignored if a type of either all or at_least is used.
fallback_ip
Specifies the IPv4, or IPv6 address of the server to which the system directs requests when it cannot use one of its pools to do so. Note that the system uses the fallback IP only if you select the fallback_ip load balancing method.

  • round-robin
  • return-to-dns
  • ratio
  • topology
  • static-persistence

  • none
The load balancing mode that the system tries if both the preferred_lb_method and alternate_lb_methods are unsuccessful in picking a pool.

server
required
Name of the server which the pool member is a part of.
monitors
(added in 2.6)

When availability_requirements.type is require, you may only have a single monitor in the monitors list.
name
required
Name of the GTM pool.
partition
(added in 2.5)
Default:
Common
Device partition to manage resources on.
password
required
The password for the user account used to connect to the BIG-IP. You can omit this option if the environment variable F5_PASSWORD is set.

The load balancing mode that the system tries first.
provider
(added in 2.5)
