# Application Reach Through - Description

Application Reach Through is available for Administrative Groups that support Multi-node Management applications. From the System Administration Tool session on any member element, you can "reach through" to the System Administration Tool of any remote member element in the group and perform programming tasks.

## Typical Application Reach Through Tasks

Typically, you use Application Reach Through to perform the following tasks on a remote element:

- change user settings through the User and Services Configuration form

- view logs, statistics, and alarm details

- issue maintenance commands

- modify hardware programming (for example, Card Assignment, Resilient T1/E1 Framers, or Quad BRI Framers)

- view modify system specific settings (for example, DHCP settings, Firewall Control, Licenses and Option Selection, or System Capacity)

- view or modify IP Network settings (for example, Spanning Tree, LAN Policy, or Layer 2 Switch) for an element

## How is Application Reach Through Supported in the Forms?

To support Application Reach Through, the System Administration Tool has been modified in MCD Release 4.0 and later software versions. The following image highlights the most significant modifications:

| Selection menu displays the name of the login element (the element that you logged into).
| Alarm Status field displays the highest alarm level for all the elements in the Administrative Group.
| Form name and the name of its element.
| The DN to Search field allows you to search for a directory number across the databases of the Administrative Group elements. Enter a directory number in the field. One of the following text strings is displayed to the right of the field: DN Found: Directory number was found in an element's database. DN Not Found: Directory number does not exist. Item Disabled: Directory number was found in an element's database, but the system is unable to reach through to the element. If the directory number is found, click Go or press the Enter keyboard key to go to the number in the form. Note that this "go to" function only applies to forms that display lists of directory numbers.
| The Show form on field allows you to select the name of an element that belongs to the Administrative Group. Select an element name and click Go. The tool presents the currently selected form for that element. If access to the form is not supported for a particular element, the element name is disabled (grayed out) in the drop-down menu and the reason is provided in brackets. (Pre 3300 ICP Release 9.0) indicates that the 3300 ICP element does not have the required 3300 ICP Release 9.0 or later software (Not shared) indicates that SDS is not enabled or not supported for the element. If Application Reach Through is not supported for the administrative group, then the field displays Not Accessible.
| The Auto Reach-Through button allows you to keep your programming session on the remote element: After you reach through to a form on a remote node (element), click this button to remain on that element. While the button is enabled , the form names listed in the Selection menu access the forms on the remote element. Click this button again to disable auto reach-through. While this button is disabled , the form names listed in the Selection menu once again access the forms on the Login node (element).
| If the Auto Reach-Through button is disabled, on the form on the Login element is accessible. If the Auto Reach-Through button is enabled, the form is accessible on remote elements selected in the Show form on field.
