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
Configuring network options for bootup
Transferring configuration and image files to/from ASR 5000 local devices
Initiating and monitoring upgrade status
The Web Element Manager further simplifies the software upgrade process by providing tools for managing system
configuration files:
Back-up Tool: Enables the Web Element Manager to transfer a copy of the configuration file currently being
used by a managed system at user-defined intervals. Files are transferred to the host server in a specific
directory. The number of files to retain in the directory is also configurable. This tool provides a useful
mechanism for testing configurations and/or quickly restoring a last-known-good configuration in the event of
an error.
Compare Tool: Provides a powerful tool for comparing the configuration files of two managed systems. Once
the two files are specified, a dialog appears displaying the two documents side-by-side. Line numbers are
added for convenience. Text additions, modifications, and deletions are displayed in different colors for easy
recognition. This tool can be useful on its own to determine variations between multiple iterations of the same
configuration file, or, when used in conjunction with the Back-up tool, it can provide an audit trail of
configuration changes that occurred during system operation.
Accounting Management
Accounting management operations allow users to examine and perform post-process statistical analysis on systems
managed by the Web Element Manager application.
The type of statistics used for element management-based accounting are called bulk statistics. Bulk statistics are
grouped into categories called schemas and are polled by the system at fixed polling intervals and then transferred to the
Web Element Manager at a different transfer intervals (defined in minutes).
