Obtaining Technical Assistance
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.
Cisco MGM has the following platform and software requirements.
The platform resources you need depend on the number of Cisco MGX 8260 Media Gateways and their configurations. Table 1 demonstrates the standard configuration for Cisco MGM Server and Client.

Operating system | Solaris 2.6 with CDE 1.3 or | Solaris 2.6 with CDE 1.3 or |
Memory | 1 GB RAM | 256MB RAM |

You need the following software for Cisco MGM 1.0:
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.
The following table describes the known problems in Cisco MGM 1.0:
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 MGCP icon does not necessary mean MGCP is activated on the chassis. | You can use Object Configuration 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 outstanding 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 indicators for some of the lines may indicate incorrect alarm information. | You may be misled about outstanding alarm on an object. | Shut down and restart MapViewer will refresh the alarm indicators |
