Provide mechanisms for viewing both current and pending alarms for both the ASR 5000 and the Web Element
Manager server.
Generate audio and visual alerts for alarms based on their severity (the Web Element Manager also supports the
configuration of a severity level for each alarm).
Maintain statistics for generated alarms.
Store alarm information in the PostgreSQL® database.
Execute scripts through the Script Server component of the application.
Send E-mail notifications and/or forward notifications to Network Management Servers (NMSs) using a
CORBA/IIOP-based Northbound Interface.

Configuration Management
The Web Element Manager implements an easy to use, point-and-click GUI for providing configuration management
for one or more systems. This GUI provides all the flexibility offered by the system‘s command Line Interface (CLI),
while providing the scalability of performing certain functions across multiple ASR 5000s. All configuration
information is stored in the PostgreSQL Database.
At the system-level, the Web Element Manager application provides support for the following:
Adding, modifying, or deleting systems to/from the management system
Performing configuration of card and port-level parameters
Adding, modifying, or deleting contexts
Configuring specific protocols and services within defined contexts such as AAA servers, PDSN services,
GGSN services, IP access lists, IP interfaces, IP routes, IP address pools, RADIUS accounting and
authentication, PPP, subscribers, and others
At the network level, the application is capable of transferring configuration and/or software images to multiple systems
simultaneously in advance to performing software upgrades.
The Web Element Manager supports the configuration of all parameters required to perform software upgrades
including:
Adding, deleting, and sorting system boot stack entries; these entries allow multiple fall-backs in the event the
system experiences an error in the loading of a particular image or configuration file
