Points to Remember

• The Cisco network management tools have been developed on the Cisco AVVID guidelines to provide centralized monitoring and management capabilities to enterprises of network environments such as WAN, wireless and mobile networks, and VLAN setups.

• CiscoView is a device management tools that uses a Graphic User Interface (GUI) to display the status of Cisco devices on the network. It also provides real-time information about the status and configuration of Cisco devices on the network.

• CiscoWorks constitutes a family of products including LAN and WAN management solutions, IP telephony network management solutions, and mobile network management.

• The Traffic Director Remote Monitor is a traffic management tool that performs traffic analysis and performance management and determines traffic utilization, broadcast levels, error rates, and number of collisions on particular ports.

• The VLAN Director Switch Management application provides management capabilities for VLAN ports.

• Cisco WAN Manager (CWM) is a multiprotocol network management application based on SNMP. It provides a number of services such as fault, configuration, performance, account and security management, and planning, modeling, and analysis.

• NetSys is a simulation tool that provides network planners, analysts, and managers with planning and analytical capabilities.

• The NetSys Baseliner is a tool that diagnoses network problems by simulating the current configuration of the network.

• The NetSys SLM suite is a policy-based network management application, which establishes service levels while defining, monitoring, and assessing network connectivity, security, and performance policies.

• Diagnostic commands are built into Cisco IOS to provide information that is used for diagnosing network problems. The important diagnostic commands are show, debug, ping, and trace.

• Cisco IOS provides a range of show commands that display information about the rate of utilization of router resources, network interface status, and router configurations.

• The ping command is used to check the connectivity between the nodes on the network.

• The debug command is an advanced command that provides high-end options for monitoring and retrieving network data for troubleshooting.

• The trace command is used to determine the route followed by the data packets on the network.

• CDP is a Cisco-proprietary protocol that functions at the Data-link layer and supports heterogeneous network layer protocols on different networks.
