Access interfaces

Overview

Each customer service is configured with at least one access interface point called a SAP. The access interface identifies the point of customer interface for a service on the managed device.

A Layer 2 or Layer 3 access interface is uniquely identified using these parameters:

Depending on the encapsulation type, a physical port or channel can have more than one access interface associated with it. Using encapsulation or a SONET/SDH channel, devices can support multiple services for a customer or for multiple customers.

Access interfaces can only be created on ports or channels that are designated as access in the physical port configuration. Access interfaces cannot be created on ports designated as core-facing network ports because these ports have a different set of features enabled in software.

Access interfaces can participate in policies. Time of day suites can also be associated with access interfaces to apply a set of time-based policies, filters, and schedulers. Configuration of access interfaces can be performed during service configuration or modification.

When you configure an access interface, consider the following:
