The Cisco Media Gateway Manager (Cisco MGM) can deploy, configure, and manage a group of Release 1.2 Cisco MGX 8260 Media Gateways in one or more Points of Presence (POP). Cisco MGM conforms to the Telecommunications Management Network (TMN) model, operating as an Element Management System (EMS) at the element management layer. Cisco MGM supports four of the five major OSI system management functional areas fault, configuration, performance, and security.

System Requirements

Cisco MGM has the following platform and software requirements.

Platform Requirements

The platform resources you need depend on the number of Cisco MGX 8260 Media Gateways and their configurations. Table 1 lists the minimum configuration for Cisco MGM Server and Client.

Table 1: Minimum Platform Requirements

Resource	Cisco MGM Server	Cisco MGM Client
Hardware	Sun Ultra 60 Workstation	Sun Ultra 5 workstation
Operating system	Solaris 2.6 with CDE 1.3 or SunOS 5.6	Solaris 2.6 with CDE 1.3 or SunOS 5.6
Memory	1 GB RAM	256MB RAM
Disk space	Four hard disks, 9GB or larger¹	One hard disk, 9GB or larger
Processor	Two x 360Mhz	333Mhz
Swap space	2GB	2GB
Monitor	17" color	17" color
Graphics card	24bit	24bit
CD ROM	Local or remote	Local or remote

¹Do not substitute a smaller number of larger drives.

Software Requirements

You need the following software for Cisco MGM 1.0.1:

Cisco EMF version 3.1
Cisco EMF version 3.1 Patch 1
Netscape 4.5 for Solaris (for Cisco WebViewer)
Cisco MGX 8260 Media Gateway, software version 1.2
Cisco Voice CORBA Gateway (VCG) version 1.0 (optional)

Feature Information

Cisco MGM supports four of the five major OSI system management functional areas fault, configuration, performance, and security. Cisco MGM also conforms to the Telecommunications Management Network (TMN) model, operating as an Element Management System (EMS) at the element management layer. As such, Cisco MGM manages a subnetwork of homogenous network elements.

Cisco MGM includes a graphical user interface that displays network information and supports device management. This interface extends the capabilities of the Cisco Element Management Framework (Cisco EMF) to include managing Cisco MGX 8260 Media Gateways. Cisco MGM includes links to two management tools, the Cisco WebViewer and the Cisco MGX 8260 command line interface, from which you configure individual nodes. Network management layer applications can communicate with Cisco MGM through an optional CORBA IDL interface provided by the Cisco Voice CORBA Gateway (Cisco VCG). This gateway is a separate product that extends the capabilities of the Cisco MGM product.

Limitations and Restrictions

Per Cisco EMF 3.1 requirement, Cisco MGM 1.0.1 only supports Solaris 2.6.
Per Cisco EMF 3.1 requirement, Cisco MGM 1.0.1 GUI will not support the Open Window environment.

Installation Notes

A basic installation requires a minimum of 2 GB of free disk space in a file system (for example /opt) for Cisco EMF and Cisco MGM.
Cisco EMF must be installed and running before Cisco MGM can be installed.
After CEMF installation is complete, execute "cemf shell" to set up the run-time environment for CEMF before executing "cemf start".

Important Notes

Do not interrupt the Cisco MGM installation or uninstallation with Ctlr-C or the kill command. After such an interruption, the system may not successfully install or uninstall Cisco MGM when you try to perform these actions again, or the system may enter an abnormal state.
Always run "cemf stop" to gracefully shut down Cisco EMF and Cisco MGM processes before rebooting the machine. If machine is accidentally rebooted (or restarted due to power failure), the Cisco MGM database integrity may be damaged, and you may need to run cemf reset and rediscover the network to restore normal operation. Running low on swap space leads to the same problem. Make sure that a minimum of 2 Gig of swap space is allocated on the server machine.
If cemf stop hangs while suspending the participant service, use /opt/cemf/bin/sysmgrClient -q to stop the Cisco EMF core processes. Before performing this operation, wait for at least one hour for the cemf stop command to complete.

: Because sysmgrClient -q may damage the database, run cemf stop then cemf reset afterwards to reset the database.

If the following error messages appear when running cemf session, please run cemf stop and cemf start to restart Cisco EMF and Cisco MGM processes.

: ERROR: "/opt/cemf/config/scripts/session" command failed.
: ERROR: Cannot connect to Session

Do not use the Deployment menu on Cisco MGM GUI to delete site objects. Doing so may cause the MapViewer window to stop working correctly. If this occurs, close the MapViewer window and restart a new one from the CEMF LaunchPad. Also try to delete one chassis at a time.
Before uninstalling Cisco MGM from a system that manages more than 10 MGX 8260 Media Gateways, delete all MGX 8260 Media Gateways from Cisco EMF GUI. Otherwise, Cisco MGM uninstall may fail.
Do not interrupt the cemf backup operation using Ctrl-C or the kill command. This may leave Cisco EMF in an inconsistent state from which you cannot recover.
The object indicator color on Cisco MGM GUI represents the highest severity of alarm on the object, but not necessarily the status of the resource on the chassis. For status of the resource that the object represents, use the Object Configuration window to query for the desired information.
The MGCP object is always shown as active on Cisco MGM GUI, even if it is not activated on the MGX8260 chassis. To query for MGCP operational status, use the Object Configuration window.
When creating DS1 lines in bulk using WebViewer or CLI, do it one card at a time; Cisco MGM may take a while to create all the lines.
SNMP v1 community strings are always scrambled in Object Configuration window of Cisco EMF GUI. To view the unscrambled community strings, display the UserAttributeTypeCMGMMGX8260 table for the desired chassis object.
Alarm propagation on the Cisco MGM GUI may not work correctly. A future Cisco EMF 3.1 patch (likely in Patch 2) will repair this problem.
The alarm indicator next to the object name on the left hand side panner of Cisco MGM GUI sometimes does not show the correct color of the highest outstanding alarm. If this occurs, close the MapViewer window and open a new one.
The installation directory of Netscape has to be the same on the Cisco EMF server and the client machines. Otherwise, launching WebViewer from client machine will fail.

Caveats

The following table describes the known problems in Cisco MGM 1.0.1:

Table 2: Bugs and Workarounds

Bug Id	Bug Description	Impact	Workaround
CSCds39117	After subchassis discovery, the MGCP object is shown as normal on the CEMF Map View (hierarchy tree and topology view). However, WebViewer shows MGCP core operational and admin status as down.	The normal status of MGCP icon on the CEMF GUI does not necessary mean MGCP is activated on the chassis.	You can use Object Configuration of the CEMF GUI to browse the operational and admin status on the MGCP
CSCds56948	Chassis sync-up does not bring out the alarms which were cleared at Event Browser which were still solid red at chassis.	Color on object indicators represent the highest severity uncleared alarm on the object, but not the status of the resource on the chassis. For status of the resource that the object represents, use the Object Configuration window to query the information.	You can still see the alarm history of the object by opening Event Browser against the object, and select Cleared alarms from the display criteria dialog
CSCds88679	When a large number of lines are created on MGX8260, the alarm indicator of some of the lines may indicate incorrect alarm information on Map Viewer (although Event Browser still shows all alarms correctly)	You may be misled about outstanding alarm on an object.	Shutting down and restarting MapViewer will correctly refresh the alarm indicators.
CSCdt01949	The user attributes, Read Only Community String and Read Write Community String, on chassis objects of CMGM are not scrambled on Object Configuration of the CEMF GUI.	Unauthorized user who can still log on to CEMF will be able to see the real read/read-write community strings being configured on the corresponding chassis.	Not applicable.
CSCdt27407	Breaking out of Cisco MGM installation / uninstallation causes the system to be in an abnormal condition.	User may not be able to install or uninstall Cisco MGM again, and the selection options may not show Cisco MGM as a selectable option.	Manually remove /var/sadm/pkg/cmgmpkgm directory, and rerun Cisco MGM installation.
CSCdt29313	Incorrect result value with D Channel deletion action.	D Channel deletion action returns incorrect status code to VCG when an out-of-range index is used.	Use 1 to 16 for D Channel index on NSC, and 1 to 168 for D Channel index on BSC.
