Specific IPAM/DHCP object types support scheduling of Port Configuration tasks as part of their object definition:

  • New IPv4 and IPv6 Networks;
  • IPv4 Reservations;
  • Fixed IPv4 Addresses;
  • Fixed IPv6 Addresses;
  • Hosts;

For all of these object types, you can click a Schedule for Later button at any step in the Wizard to commit the currently defined settings for the new object to a new Grid Manager task. For example, consider creating a new IPv4 network. After defining the IP address for the new network, you simply wish to create it and not to define any further configurations. Click Schedule for Later to skip the intervening Wizard steps and display the final Scheduling page of the Wizard, an example of which appears in Figure 1.7.
Figure 1.7 Create Network Schedule for Later page

  1. To create the new object immediately, select Now and click Save & Close.
  2. You can choose to have Grid Manager create the object at a later time. To do so, select Later. Choose a Selected time by entering or selecting a Start Date (click the calendar icon to choose a calendar date) and a Start Time (click the clock icon to choose a specific time in fifteen minute increments), and choose a Time Zone.

When you step through the entire Wizard process (without clicking Schedule for Later) and if you also define port configuration settings, the object creation wizards provide a final Scheduling page with separate scheduling definitions, for the object and for the object's port configuration, as shown in Figure 1.8:
Figure 1.8 Scheduling Create Object and Port Configuration



The final step for creating the Network, Fixed Address, Host, or IP reservation is to define when the task executes, including associated port control definitions. The port configuration is performed in a separate task, defined on the same wizard page. The port configuration task can be done at the same time that Grid Manager provisions the object, or may be scheduled for a later time.

1. To create the new object immediately, select Now.

By selecting Now, no task is created by Grid Manager and it simply creates the object. The completed object creation appears in the audit log (for related information, see the Viewing Tasks). Grid Manager creates a task for object creation only when you use Schedule for Later. Also, all port configuration and network provisioning instances create a new task under the Task Manager.

2. You can instruct Grid Manager to create the network at a later time. To do so, select Later. Choose a Selected time by entering or selecting a Start Date (click the calendar icon to choose a calendar date) and a Start Time (click the clock icon to choose a specific time in fifteen minute increments), and choose a Time Zone.

3. Port configuration and network provisioning tasks can be synchronized to take place at the same time as the creation of the new object under IPAM/DHCP; if so, keep the At same time as above option.

a. You can also schedule the task at a different time. To do so, select Later (under Port Configuration). Choose a Selected time by entering or selecting a Start Date (click the calendar icon to choose a calendar date) and a Start Time (click the clock icon to choose a specific time in fifteen minute increments), and choose a Time Zone.

The Port Configuration provision cannot take place at a schedule time or date before the associated object creation.
Object creation must successfully complete before its associated port configuration task begins.

4. Click Save & Close to complete the configuration.


Note: Port configuration tasks (or any operation that queries for or changes device configurations through Grid Manager, including Discovery) are subject to a feature called Blackout Periods, which are defined elsewhere in Grid Manager. Blackouts are a scheduled feature that instructs Grid Manager not to perform Discovery operations and Port Control/provisioning operations on the managed network at specified times, days and dates. See the section Defining Blackout Periods for details.



Scheduling Creation of new IPv4/IPv6 Networks and Associated Device Provisioning

Defining new IP networks in Grid Manager supports scheduled Network Provisioning tasks on discovered and managed infrastructure devices as part of their object definition:

  • Provisioning IPv4 networks
  • Provisioning IPv6 networks

These networks are managed on the IPAM and DHCP pages (unless the network is excluded from DHCP), with the difference that Network Insight provisions the network directly on the specified router or switch-router. You may define new networks under IPAM and under DHCP as one scheduled task, and may provision those networks on devices that are discovered and managed under Network Insight, as another scheduled task.
Both tasks may be separately scheduled. They can take place immediately: the network is created first, then the network is provisioned on the device, along with the necessary device configuration, which Grid Manager also handles using the required CLI credentials; or either or both tasks may be scheduled for a later time.
The scheduled IPv4 or IPv6 network must be created under IPAM or DHCP in Grid Manager before scheduled device configuration or provisioning of networks on those devices can take place.
When you define a new network under IPAM or DHCP, you can click Schedule for Later in any Wizard page to skip further configuration in the Wizard and commit the network settings to Grid Manager. If you do not want to provision the network, clicking Schedule for Later will display a shorter scheduling page:

Figure 1.9 Create Network Schedule page (After clicking Schedule for Later)


In cases of this type, you schedule or execute only a single task: creating the new network under DHCP/IPAM. No network provisioning task takes place.
When you provision the network without clicking Schedule for Later, the wizard provides a final Scheduling page with an expanded set of two task schedules as shown in Figure 1.10:
Figure 1.10 Scheduling Add Network and Network Provisioning Tasks

  1. To immediately create the new network, you can select Now.
  2. You can choose to have Grid Manager create the network at a later time. To do so, select Later. Choose a Selected time by entering or selecting a Start Date (click the calendar icon to choose a calendar date) and a Start Time (click the clock icon to choose a specific time in fifteen minute increments), and choose a Time Zone.
  3. The Network Provisioning task can be synchronized to take place at the same time as the creation of the new network under IPAM/DHCP; if so, keep the At same time as above option.
  4. You can also provision the network onto the device at a differently scheduled time. To do so, select Later (under Network Provisioning). Choose a Selected time by entering or selecting a Start Date (click the calendar icon to choose a calendar date) and a Start Time (click the clock icon to choose a specific time in fifteen minute increments), and choose a Time Zone.

Note: Network provisioning tasks (or any operation that queries for or changes device configurations through Grid Manager, including Discovery) are subject to a feature called Blackout periods, which are defined elsewhere in Grid Manager. Blackouts are a scheduled feature that instructs Grid Manager not to perform Discovery operations and Port Control/provisioning operations on the managed network at specified times, days and dates. See the section Defining Blackout Periods for details.


Scheduling Additions and Modifications

You can schedule the addition and modification of an object. For example, you can schedule the addition of a DNS forward zone or the modification of a fixed address. After you schedule a task, administrators cannot modify the object associated with the scheduled task until after the appliance executes the task. However, the object can still be updated with DHCP leases and other system services.
To schedule an addition or a modification:

  1. Add or modify a record following the instructions described in this guide.
  2. Click the Schedule icon at the top of the corresponding wizard or editor.
  3. In the Schedule Change panel, complete the following:
    • Now: Select this to have the appliance perform the task when you save the entry. This is selected by default when there is no scheduled task associated with the object.
    • Later: Select this to schedule the task for a later date and time. Complete the following:
      • Date: Enter a date in YYYY-MM-DD (year-month-day) format. The appliance displays today's date. You can also click the calendar icon to select a date from the calendar widget.
      • Time: Enter a time in hh:mm:ss AM/PM (hours:minutes:seconds AM or PM) format. You can also select a time from the drop-down list by clicking the time icon.

Viewing Scheduled Tasks

After you schedule a task, you can view the pending task in the Administration tab -> Workflow tab -> Task Manager tab. For more information, see Viewing Tasks. Superusers can view all scheduled tasks, and
limited-access admins can view their own scheduled tasks.
In certain panels such as the Network list panel and Smart Folders, Grid Manager displays a calendar icon next to objects that are associated with scheduled tasks, except for the addition of an object. You can click the icon to view the configuration and schedule. You can also reschedule the task if you are the owner of the task, a superuser, or an approver of the task (after you have approved it). In the corresponding editor, the Schedule icon is green when there is a pending scheduled task. For information, see Icons for Scheduled Tasks.

Icons for Scheduled Tasks

Grid Manager displays a scheduled task icon next to an object that is associated with a scheduled task (except for the addition of an object), as shown in Figure 1.11. When you mouse over the icon, an informational dialog box appears displaying the type of action, the date and time of the scheduled task, and the person who scheduled the task.
You can click the icon and Grid Manager displays the corresponding editor (for modification) or the Scheduled Deletion dialog box (for deletion) in the read-only mode. If you are viewing a task that you scheduled, you can modify and save the schedule, but you cannot modify the configuration of the object. If you are not the owner of a scheduled modification or a superuser, you can only view the information. You cannot reschedule the task. If you are not the owner of a scheduled deletion or a superuser, Grid Manager does not display the Scheduled Deletion dialog box when you click the icon.
