How do I manage permissions for DNS GSLB
objects?
F5 BIG-IQ Centralized Management makes it
straightforward for you to manage permissions that allow users to view only
the specific DNS GSLB objects you assign to them.
To provide permissions for a specific set of objects, you complete these
tasks.
- Add a custom resource group- In this task, you specify the GSLB objects that you want this user to work with. You create a resource group for each collection of objects that you want to assign to a user.
- Add a custom role- Next, you associate the GSLB Viewer role type with the resource groups that contain the objects you want your delegates to view. For example, if you had a resource group made up of two wide IPs, one namedSeattlePrimeand the other namedSeattleSecond, you might name this roleviewSeattle.
- Add a custom user- Finally, you create a user and assign a custom role to that user. The role gives that user permissions to view the objects that belong to the objects in the resource group. In the current example, you could assign your custom user to theviewSeattlerole to give that user the ability to view the GSLB objects in the two Seattle wide IPs.
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?

.How do I manage GSLB
pools in BIG-IQ?
Virtual server pools host the content for which your wide IPs load balance
the traffic in your GSLB domain.
The workflows for creating a new pool or changing the settings for a
pool that already reside on devices in a managed sync group are very similar. In each
case, there are four tasks to perform.
This figure illustrates the workflow you perform to manage the pools in a
sync group. Changing the settings or creating the pool is the second step in this process.
Change pool
workflow

You can view the GSLB pools configured for the DNS sync groups you manage by
navigating to
. From there, click a pool to edit it, or click Create
to set up a new one.View GSLB objects
Before you can use a BIG-IQ to manage DNS GSLB objects on a managed device, you must configure at least one Datacenter on that device using the BIG-IP user interface.
When you use F5 BIG-IQ Centralized Management to manage your DNS sync group, you can view the GSLB objects that are defined on devices in the sync group.
- At the top of the screen, clickConfiguration.
- On the left, click, and then select the object type that you want to view.The screen displays a list of the selected object type that are defined on devices managed by this BIG-IQ system. For each object (except iRules, topology records, or topology regions), icons describe the health status and availability.
- To view overview information about a particular object, select the check box for that object.An overview panel and a related items panel display for this object.
- To see a list of related items for a GSLB object:
- Select the check box for that object.
- In the Related Items panel, clickShow.You can view the list of related items; and, for many of the items, you can click a link to view properties for that item.
- To view the general properties for a GSLB object, click the name of that object.The screen displays the properties for the selected object.
Create a GSLB pool
Create a GSLB pool so that you can manage the
virtual servers that host the content of your domain.
- At the top of the screen, clickConfiguration, then, on the left, click .The screen displays the list of pools defined on this device.
- ClickCreate.The New Pool screen opens.
- Type aNamefor the GSLB pool.
- Select aSync Groupfor the pool.
- Select theTypeof pool.
- Specify the additional settings needed to suit your requirements for this pool.Name,Sync Group, andTypeare the only required parameters when you create a pool. The remaining parameters on this screen are optional and perform the same function as they do when you configure a pool on a BIG-IP device.For details about the purpose or function of a particular setting, refer to the BIG-IP reference information onsupport.f5.com.
- ClickSave & Close.The system creates the new pool and adds it to the list of pools.
Changes that you make 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. Now that you have created a pool, you can add
pool members to it. For details about adding a new member, refer to
Create a GSLB
pool member
on support.f5.com
.When you finish
specifying the settings for this pool, the next step is to evaluate and then deploy
the changes to devices in the sync group. Until you deploy the changes stored in the
pending version, objects on the devices in the sync group are not
changed.
Edit a GSLB pool
You can view and modify the properties for
existing GSLB pools. Since you are working with an existing pool, you can modify only
some settings.
- At the top of the screen, clickConfiguration, then, on the left, click .The screen displays the list of pools defined on this device.
- Click the name of the pool you want to edit.Unless noted here, the parameters on this screen perform the same function as they do when you configure a pool on a BIG-IP device. For details about the purpose or function of a particular setting, refer to the BIG-IP reference information onsupport.f5.com.The screen displays the current settings for the selected pool.
- ToEnable,Disable, orDeletea pool member from this pool, select the check box for that member, then click the appropriate button.
- Make the changes to the settings you want to revise and then, when your edits are complete, clickSave & Close.The system updates the pool with the settings you specified.
Changes that you make 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. When you finish revising the settings for
this pool, the next step is to evaluate and then deploy the changes to devices in the
sync group. Until you deploy the changes stored in the pending version, objects on the
devices in the sync group are not changed.
Add members to a GSLB pool
Before you can add a GSLB pool member, the
virtual server you plan to use must already exist. For details on creating a GSLB
server, refer to
Create a GSLB server
on support.f5.com
. You can use the BIG-IQ to add members to a GSLB
pool on a managed BIG-IP device.
- At the top of the screen, clickConfiguration, then, on the left, click .The screen displays the list of pools defined on this device.
- Click the name of the pool you want to add members to.Unless noted here, the parameters on this screen perform the same function as they do when you configure a pool on a BIG-IP device. For details about the purpose or function of a particular setting, refer to the BIG-IP reference information onsupport.f5.com.The screen displays the current settings for the selected pool.
- Near the bottom of the screen, clickNew GSLB Pool Member.
- FromVirtual Servers, select the member that you want to add, and then type in theRatioweight that you want to assign to this pool member. This weight determines the frequency at which this pool member is selected for load balancing.You can use theAddicon to add more members to this pool. Or if you change your mind about adding a member, you can use theRemoveicon to delete it.
- Make any other changes to the settings for this pool, and then when your edits are complete, clickSave & Close.The system updates the pool with the settings you specified.
Changes that you make 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. When you finish revising the settings for
this pool, the next step is to evaluate and then deploy the changes to devices in the
sync group. Until you deploy the changes stored in the pending version, objects on the
devices in the sync group are not changed.
