Discovering and Assigning All N-PE Devices
Pre-staging all Network Activate assignment recommendations is a powerful yet simple way to prepare your devices for provisioning. This procedure provides the pre-staging steps that accept all system recommendations. To pre-stage devices and make exceptions to the system recommendations, see Discovering and Assigning N-PE Devices with Exceptions.
Before discovering and assigning N-PE devices, you must have already run device discovery. See Discovering Devices in the Junos Space Network Application Platform User Guide.
Pre-staging has two parts:
Discovering Device Roles
To discover the roles of devices found during element discovery:
- In the Network Activate task pane, select Prestage Devices > Manage Device Roles > Discover
The Role Discovery Status window shows the discovery of unassigned devices found in the database.:
The graph portion of this example shows how many of the unassigned devices the pre-staging rules determined could be assigned the N-PE role and how many could be assigned the P role. The UNKNOWN bar indicates devices that had no MPLS role assigned but for which the Network Activate software was unable to recommend a role.
You cannot discover a device as a PE device if no user-to-network interfaces (UNIs) are available in the device.
The Network Activate application throws the following error message:
2012-06-08 10:17:23,446 ERROR [PreStageDeviceManagerBean] (PreStageDeviceManagerBean#savePreStageDeviceList Thread-6894 (group:HornetQ-client-global-threads-1332782448):) No ge/fe/at/t1 interfaces in this PE device: junos-mx480-space; it can only be used for virtual routers
- To view the devices for which the Network Activate software
recommends the PE role, click on the N_PE bar.
The Assign Roles window appears.
The question mark on each icon indicates that the device role has not yet been assigned.
Device role discovery is now complete. To assign device and interface roles, follow the steps in the next section, Assigning Device Roles.
Assigning Device Roles
If you need to exclude devices from role assignment, or you need to exclude interfaces from the list of interfaces that can be used as UNIs, use the procedures documented in Discovering and Assigning N-PE Devices with Exceptions.
To assign all discovered roles and interfaces:
- In the Network Activate task pane, select Prestage Devices > Manage Device Roles > Assign Roles.
- In the Assign Roles page, click Multiple in the quick view pane and select all devices.
- Open the Actions menu and select Assign NPE Role.
- In the confirmation window, click Assign.
- To view the assignment status, in the Job Management window, click the job ID of the assignment job.
The Job Management page shows the progress and status of the role assignment job. See Viewing Jobs in the Junos Space Network Application Platform User Guide for details.
While the job is ongoing, you cannot make additional assignments from the Assign Roles page. The Assign NPE Role action is dimmed to indicate you cannot select it.
