Network Analysis Module NAM easy monitoring and switching network

Most network administrators use port mirroring, data generation technology, or passive networks to configure network detectors. Although these solutions can work barely, they will have negative effects, affect network performance and response speed, and perform tedious and slow operations.

To address these problems, Cisco has released its network analysis module NAM. NAM is designed for Cisco switches of the Catalyst 5000, 6000, and 6500 series. It is similar to a protocol analyzer and integrates embedded instrumentation and QoS tools. With NAM, network administrators can select the port, Ethernet channel, and switch VLAN, or directly send data to NAM for inspection.

After the NAM module is installed on a vswitch, you can use the Catalyst command to complete basic IP configuration. After assigning an IP address to NAM and providing a default path, you can start to use it. You do not need to install any software on your terminal.

After NAM is configured on the network, it can be used to monitor real-time communication channels, set selected options, and monitor selected communication channels. By using the NAM network to set some ports for the switch, you can monitor the selected communication channel immediately.

Based on the basic monitor, Cisco introduced some VoIP QoS monitoring options in version 2.1 of NAM software. Using this version, network administrators can predict network usage by analyzing the noise of communication channels, record the round-trip delay time, monitor the degradation of quality, and measure the response time between devices. It can also monitor the response time between network devices and VoIP phones.

Network administrators can also view statistical data, such as MAC history tables, application utilization levels, and network utilization levels. NAM is not only a simple monitor, but can also use NAM to set alarms. It can set unstable networks, H.323 delays, and other problems as alarm conditions.
