Setting Trap Managers

Use the following syntax to configure the BNM interface:

shelf.1.3.ASC.a > cnfbnmif -if <interfaceFormat>

<interfaceFormat> = 2-3, 2: UNI, 3: NNI

Configure the BNM interface to UNI format,

shelf.1.3.ASC.a > cnfbnmif -if 2

If the BNM-T3 card is being used, the ATM line must be configured with PLCP.

Note The BNM interface cannot be configured while connections exist on the MGX 8220 shelf. The clrallcnf command can be entered to clear the entire configuration. This command will also reset the MGX 8220 shelf and terminate all telnet sessions.

The interface format can be confirmed with the dspbnmif command and the response of “bnmLineInterfaceFormat: bnmUni.”

Setting Trap Managers

In stand-alone applications, trap managers are configured through the CLI entering either the cnftrapmgr command or the addtrapmgr command.

Trap managers registered (added) entering the cnftrapmgr command will age. That is to say the trap manager will be disabled automatically after 30 minutes and must be reregistered if it is to continue to exist. The function of reregistering is normally accomplished by the Cisco WAN Manager (CWM), but since CWM cannot be used for stand-alone applications, there is no method for reregistering trap managers.

In stand-alone applications, therefore, the addtrapmgr command should be entered to register a trap manager. Using this command the trap manager does not age and exists until de registered by the deltrapmgr command. Once a trap manager is registered by the addtrapmgr command it can be modified by the cnftrapmgr command and the trap manager will still not age.

Current trap managers can be displayed using either the dsptrapmgrs or dsptrapmgr commands. The dsptrapmgrs command displays all current trap managers but does not include time-out information. The dsptrapmgr command displays the status for a single specified trap manager including the time-out status.

Refer to the Cisco MGX 8220 Command Reference for details of these commands.

VPI/VCI Mapping

When creating connections on the MGX 8220 shelf the user does not explicitly assign VPI and VCI values. Instead, the MGX 8220 shelf takes user-entered values such as DLCI, LCN, and so forth, and uses mapping algorithms to calculate VPI/VCI values. In stand-alone applications, the user needs to know how this mapping works since these VPI and VCI values must be configured into the connected router or ATM switch.

MGX 8220 specifications

The Cisco Systems MGX 8220 is a versatile, high-performance media gateway that has become an integral component in the telecommunications infrastructure. Designed to facilitate the transition from traditional circuit-switched networks to advanced packet-switched environments, the MGX 8220 supports a wide array of voice, video, and data services, making it an essential tool for service providers and enterprises seeking to enhance their network capabilities.

One of the key features of the MGX 8220 is its robust signaling and media processing capabilities. Equipped with support for both Voice over IP (VoIP) and traditional telephony protocols, this gateway enables seamless integration of different communication formats. It boasts a modular architecture, which allows for the addition or removal of various line cards to meet changing demands and technology advancements. This modularity provides operators with the flexibility to scale their services without significant overhauls to their existing infrastructure.

The MGX 8220 is capable of delivering high-density media handling for a multitude of services. With its support for ATM and IP networks, the gateway can handle TDM (Time-Division Multiplexing) to packet voice conversions efficiently. It is designed to optimize network resources by dynamically allocating bandwidth based on traffic requirements, thus ensuring efficient use of network resources and improved performance.

Another significant characteristic of the MGX 8220 is its enhanced quality of service (QoS) features. This capability ensures that voice and video traffic is prioritized appropriately, minimizing latency and jitter while maximizing overall call quality. By employing sophisticated traffic management techniques, the MGX 8220 can deliver a superior user experience, which is critical for any service provider aiming to offer competitive communication solutions.

Furthermore, the gateway includes built-in security features to protect against unauthorized access and ensure the integrity of sensitive data. This includes encryption for voice and video transmission, as well as support for secure signaling protocols.

Overall, the Cisco Systems MGX 8220 stands out as a comprehensive media gateway solution, providing essential functionalities for modern communication needs. Its combination of modularity, high-density processing, effective QoS management, and security features makes it a compelling choice for organizations looking to modernize their telecommunications infrastructure while ensuring reliability and performance. As businesses continue to evolve and demand more from their networks, the MGX 8220 offers a pathway to future-ready communications.
