Configuring the Port Queue

cnfportq "QueueNo. MaxQdepth EFCIThresh"

This command can be used to configure the maximum queue depth and the EFCI threshold for the QueueNo. (1...8)

The Maximum Qdepth of the queue should be less if the AIM group is carrying delay-sensitive traffic (for example, voice, video).

Sample Data

cnfportq "1 50 50"

The maximum Qdepth could be maximum possible, and EFCI threshold could be less (ForeSight can kick in quickly, if Q starts building up) for AIM group carrying nondelay-sensitive data traffic.

Sample Data

cnfportq "1 500 15"

dspportq

dspportq “PortNo”

PortNo could be 1...8. QueueNo can be only 1. This command will display the queue configuration for the corresponding queue. It will also show the number of cells discarded due to Qfull condition on this queue.

Example display

AXIS18.1.13.IMATM.a > dspportq "1"

ServicePortNum:1

QueueNumber:1

PortBinState:Enabled

QueueDepth(cells):9216

EFCIThreshold(cells):7372

EgressQFullDiscardedCells: 0

Syntax : dspportq "port_num"

Where port number -- values ranging from 1-8

Note The “EgressQFullDiscardedCells” is cleared with the clrportcnt command.

clrportcnt 1

This command will clear the EgressQFullDiscardedCells.

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.
