Troubleshooting N-PE Devices Before Provisioning a Service

 

You can use the Troubleshoot option in Network Activate to check PE router configurations before you deploy a new service or troubleshoot PE router configurations if you are unable to deploy a new service.

To check the configuration on a PE router, follow these steps:

  1. In the Network Activate task pane, select Prestage Devices > Manage Device Roles

    The Manage Device Roles page appears displaying all devices on the network that are assigned the N-PE role

  2. Select the device that you want to troubleshoot.
  3. In the Actions menu, select Troubleshoot.

    The Troubleshoot Device page appears. The table here describes the show commands that you can run to check the configuration on a N-PE device.

    Table 1: Commands Available in the Troubleshoot Device page
