Cisco Systems ASR 1000 manual Prerequisites for Implementing Media Address Pools

C H A P T E R 4

Media Address Pools

You can configure Integrated Session Border Controller (SBC) with a single media address or a range of sequential media addresses. In addition, you can define one or more permissible port ranges for the configured addresses. This feature allows the administrator to configure or restrict the data border element (DBE) address by address pool with or without port range, and define class of service (CoS) affinity for each port range.

For a complete description of commands used in this chapter, refer to the Cisco IOS Integrated Session Border Controller Command Reference.
