Overview

Cisco Media Gateway Manager (MGM) operates as a component of Cisco's Element Management Framework (EMF) software. Cisco MGM enables you to deploy, configure, and manage Cisco MGX 8000 Series Carrier Voice Gateways that utilize the Cisco PXM1 Processor Switch Module.

Cisco MGM provides a graphical user interface (GUI) for the display of network information and device management, including access to media gateway controllers (MGCs) functioning in the network.

Cisco MGM Architecture

Cisco MGM extends the functionality of Cisco EMF to include management of Cisco MGX 8000 Series Carrier Voice Gateways, as well as supported media gateway controllers (MGCs). Figure 1-1 provides a simple view of Cisco MGM's location in a voice gateway network.

User Interfaces

Cisco MGM provides a graphical user interface (GUI) using UNIX Motif. For device-specific configuration, Cisco MGM also provides access to the CiscoView GUI, as well as to command line interface functions through telnet sessions.

For detailed information on CiscoView, refer to the following documents:

Supported Protocols

Cisco MGM supports the following protocols as part of its overall management capabilities:

CEMF Event Channel
HTTP
Telnet
TFTP
SNMPv1
SNMPv2c
CORBA

Features

Cisco MGM provides a powerful range of network management capabilities, including support for network configuration, administration, fault and performance management, and security.

Configuration

Cisco MGM configuration capabilities include the following features:

Auto discovery and topology views of Cisco MGX 8000 Series Carrier Voice Gateways
Auto discovery of media gateway controllers (MGCs)
Provisioning and queries of Cisco MGX 8000 Series service modules, lines, and ports. (This function is accessed through CiscoView.)
Maintenance state support
Software image downloads
Configuration save and restore
SNMPv1 community string configuration
Menu-launched telnet sessions for CLI device management

Administration

Cisco MGM administration capabilities provide database support for Cisco MGX 8000 Series components, including:

Chassis
PXM1 cards and lines
Voice Interworking Service Module (VISM/VISM-PR) cards and lines
Route Processor Module (RPM-PR) cards and lines
Service Redundancy Module (SRM and SRM-E) cards and lines

Cisco MGM performs asynchronous database updates in response to network equipment configuration and status changes.

Fault Management

Cisco MGM provides consolidated alarm viewing and filtering through the use of the Cisco EMF event browser interface. Cisco MGM displays alarms and events on a color-coded topology map. Fault management functions include:

Alarm monitoring
Alarm filtering
Assignment/Deletion
Acknowledgement
Alarm based performance threshold alerts
Trap registration and forwarding of traps to remote SNMP managers

Performance Management

Cisco MGM performance management capabilities include threshold and call related statistics using CiscoView and the appropriate MGC element management systems.

CiscoView provides device-specific performance management, including the following information:

LAPD Statistics
Session Set Counters
Session Group Counters
RUDP Statistics and Counters
SVC Statistics Counters
Bearer Statistical Counters
HDLC Counters
DSX1 Line Real Time Counters

All statistics data are collected in real-time, no history is stored.

Security

Cisco MGM security uses the mechanisms of Cisco EMF, which authenticates users based on names and passwords. When using CLI management interfaces, the Cisco MGX 8000 Series gateways also authenticate users based on user accounts. Security profiles define access rights for typical users, from administrators to guests.

Messages between Cisco MGM and network elements are made secure through SNMP community strings. To control access, you configure unique community strings known by all network elements.

Cisco Info Center Support

Cisco MGM provides an interface to the Cisco Info Center (CIC) through use of the Cisco EMF event channel. The Cisco Info Center is purchased as a separate product from Cisco MGM.

CIC provides service-level alarm monitoring and diagnostics tools for network fault and performance monitoring, network trouble isolation, and real-time service-level management for large networks. CIC helps operators focus on important network events, offering a combination of alarm processing rules, filtering, customizable alarm viewing, and partitioning. CIC provides a highly configurable client/server application that can consolidate, duplicate, filter, and correlate fault information from multiple network layers.

CIC is the fault management component of the Cisco Service Management (CSM) infrastructure that provides end-to-end service management solutions for service provider and large enterprise networks. Operating at the service and network levels, CIC interacts with other management tools within the CSM product suite to provide customer-focused, service-level monitoring and network partitioning for Virtual Private Network and Customer Network Management services. CIC works in conjunction with network element management software such as Wide Area Network Manager to provide fault and alarm management across local and wide area networks.
