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 manage a GSLB wide IP in
BIG-IQ?
A wide IP maps a fully-qualified domain name (FQDN) to one or more pools
of virtual servers that host the content of a domain. When a local domain name server issues a
DNS name resolution for a wide IP, the configuration of the wide IP indicates which pools of
virtual servers are eligible to respond to the request, and which load balancing methods
BIG-IP DNS uses to select the pool.
The workflows for creating a new wide IP or changing the settings for a
wide IP 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 wide IPs in
a sync group. Changing the settings or creating the wide IP is the second step in this
process.
Change GSLB wide IP
workflow

You can view the GSLB wide IPs configured for the DNS sync groups you
manage by navigating to
. From there, click a wide IP 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 wide
IP
You create a GSLB wide IP so that you can manage
pools of 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 wide IPs defined on this device.
- ClickCreate.The New Wide IP screen opens.
- Type aNamefor the GSLB wide IP.
- Select aSync Groupfor the wide IP.
- Select theTypeof wide IP.
- Specify the additional settings needed to suit the requirements for this wide IP.Name,Sync Group, andTypeare the only required parameters when you create a wide IP. The remaining parameters on this screen are optional, and perform the same function as they do when you configure a wide IP on a BIG-IP device.For details about the purpose or function of a particular setting, refer to the BIG-IP system reference information onsupport.f5.com.
- ClickSave & Close.The system creates the new wide IP and adds it to the list of wide IPs.
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 specifying the settings for
this wide IP, you need 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 wide IP
You can view and modify the properties for
existing GSLB wide IPs. Since you are working with an existing wide IP, you can modify
only some settings.
- At the top of the screen, clickConfiguration, then, on the left, click .The screen displays the list of wide IPs defined on this device.
- Click the name of the wide IP you want to edit.Unless noted here, the parameters on this screen perform the same function as they do when you configure a wide IP on a BIG-IP device. For details about the purpose or function of a particular setting, refer to the BIG-IP system reference information onsupport.f5.com.The screen displays the current settings for the selected wide IP.
- Make the changes to the settings you want to revise and then, when your edits are complete, clickSave & Close.The system updates the wide IP with the settings you specified.
