Table 6-1 lists the topics discussed in this chapter and their associated sections.
You can organize and manage network devices such as aggregation routers with the BAC Web UI. You organize devices within administrative networks. Administrative networks provide a partitioning mechanism so that a service provider can view only the devices on its network.
 |
Note Before you add network devices, make sure that you first add service providers and network resources to ensure that the appropriate partitioning of network views. For more information, see "Managing Service Providers and Subscriber Groups" and "Managing Network Services." |
Use BAC for device configuration and inventory management, including the assignment of network resources to devices; for example, associating a AAA server to a router in a PTA aggregation scenario.
When you create these devices in BAC, you can also initiate an automatic discovery process that produces and lists an inventory of each device's network cards, ports, and connection endpoints. BAC displays these in an inventory tree.
Creating administrative networks enables you to partition your network views so that you provide specific views to defined communities of interest. A wholesale network access provider first creates administrative networks for the network service providers accessing its broadband facilities. You organize and manage administrative networks so that you can then partition network devices and subscribers functionally, geographically, or technologically.
When you create an administrative network, you:
When you create an administrative network, you step through a series of web pages to set the fields listed in Table 6-2.
