Management Interface
This interface provides the point of attachment to the management network. The interface supports remote access to the
command line interface (CLI). It also supports Common Object Request Broker Architecture (CORBA)-based
management via the Web Element Manager application, and event notification via the Simple Network Management
Protocol (SNMP).

cards.
Bindings
A binding is an association between elements within the system. There are two types of bindings: static and dynamic.
Static binding is accomplished through system configuration. Static bindings associate:
A specific logical interface (configured within a particular context) to a physical port. Once the interface is
bound, traffic can flow through the context as if it were any physically-defined circuit. Static bindings support
any encapsulation method over any interface and port type.
any encapsulation method over any interface and port type.
A service to an IP address assigned to a logical interface within the same context. This allows the interface to
take on the characteristics (that is, support the protocols) required by the service.
Dynamic binding associates a subscriber to a specific egress context based on the configuration of their profile or
system parameters. This provides a higher degree of deployment flexibility, as it allows a wireless carrier to support
multiple services and facilitates seamless connections to multiple networks.

Management ports can only be bound in the local context. Traffic or subscriber ports can only be bound in a non-local
context.

Services
Configure services within a context to enable certain functionality. The following are examples of services you can
configure on the system, subject to licensing availability and platform type:
