Managing Pool & Pool Members
How do I change object settings on a managed device?
To change the object settings on a managed device, there are four tasks to perform.
This figure illustrates the workflow you perform to manage the objects on BIG-IP® devices. Changing the settings is the second step in this process.
Change managed object workflow
What pool and pool member management tasks can I perform?
There are a number of ways you can use BIG-IQ® Centralized Management to manage the pools and pool members on your managed BIG-IP devices:
- Create a new pool or pool member.
- Modify an existing pool or pool member.
- View statistics for a pool.
- Deploy the pool and pool member immediately
to your managed device; for pool members, you can enable, disable, or force offline
immediately. Note: You (or someone else) can also deploy your changes later. For more information about managing changes, look on support.F5.com in F5 BIG-IQ Centralized Management: Device for the topic: Deploying Changes.
- Add or remove permissions for a pool or pool member and assign them to roles that have been defined on this BIG-IQ system. For more information about managing permissions, look on support.F5.com in F5 BIG-IQ Centralized Management: Authentication, Roles, and User Management.

How do I delegate pool member management tasks?
BIG-IQ® Centralized Management makes it straightforward for you to delegate users permissions (enable, disable, or force offline) that allow them to manage pool members only for the specific pools you assign to them.
To provide enable, disable, and force offline permissions for a specific set of pool members, you need to perform three tasks. For the sake of explanation, consider an example scenario in which you have 10 pools that service your Alaska clients and you want to delegate management authority for the pool members in those pools. Here are the tasks you would perform:
- Add a custom resource group and assign pools to it - in this task, you specify the pools that you want your delegate to manage and name the resource group (for example, Alaska Services Pools).
-
Add a custom role - when you create a
role you specify a role type and associate it with a resource group. The role type
defines the permissions, and the resource group defines the objects to which those
permissions apply.
- You name the new role something intuitive (for example: Alaska Services Pool Manager).
- You assign the built in role type named Pool Member Operator. This role has all the permissions (enable , disable, and force offline) needed, so you do not need a custom role.
- Assign the role to the Alaska Services Pools resource group you just created.
- Add a custom user - Finally, you create a user and assign them the Alaska Services Pool Manager role. Users who log in with this user name will have the permissions (defined by the role type) and access scope (defined by the resource group) to manage the pool members that belong to the 10 pools in the Alaska Services Pools resource group.
For step by step guidance on each of these tasks, refer to How do I give users customized permissions to specific BIG-IP resources based on their job responsibilities? on support.f5.com
Create a new node
You can use the BIG-IQ Local Traffic interface to add a node to a managed device.
Nodes are the basis for creating a load balancing pool. For any server that you want to be part of a load balancing pool, you must first create a node, that is, designate that server as a node. After designating the server as node, you can add the node to a pool as a pool member. You can also associate a health monitor with the node, to report the status of that server.

Make bulk changes to a set of pool members
- When you click Change Now, it triggers an immediate deployment to the devices that house the impacted pool members.
- When you click Change Later, changes that you make to pool members are made only to the pending version. The pending version serves as a repository for changes you stage before deploying them to the managed device. Object settings for the pending version are not the same as the object settings on the actual BIG-IP device until they are deployed or discarded.
