Web Element Manager (WEM)
The WEM is a server-based application providing complete element management of the system. The UNIX-based
server application works with the network elements within the system using the Common Object Request Broker
Architecture (CORBA) standard.
Important: For information on WEM administration, refer to the Web Element Manager Installation and
Administration Guide.
WEM server must be set up with access to the following networks:
Internet: To communicate with the Master Content Rating Database Server (MCRDBS) which provides update
files.
For Category-based Content Filtering, the WEM application includes the following features:
Single point of management for a large Content Filtering Service operator deployment:
Content Filtering service configuration and monitoring
Alarm/trap management
Configures and manages the operator-defined White/Black static rating database (WBLIST) for the network
(WBLIST is maintained in SFMDB format)
Content filtering database management functions:
Performs database processing in the background
Imports full and incremental SFMDB and SFMDB-INC files from the MCRDBS on a configured
schedule
Processes incremental SFMDB-INC updates from MCRDBS maintaining an updated SFMDB file
Merge the operator‘s WBLIST database with the most recent SFMDB creating a SFCMDB
Computes an incremental update to the OPTCMDB-INC suitable for updating the Content Filtering
subsystem that contains a previous version OPTCMDB
Distributes OPTCMDB/OPTCMDB-INC files to the chassis automatically at configured interval
