A Buyer’s Guide to Network Management Software

Overview Network Management is a set of activities that aim to ensure the health and availability of a network. Network management software allows the administrators to do the set of activities to manage the network and the nodes attached to the network. Network Management activities cover areas such as security, configuration management, change management, incident management, problem management and network inventory maintenance. Network Management activities are often automated through the use of monitoring and reporting utilities. Network management software is not just for monitoring and resolving the issues. It is for complete proactive and automatic network management strategy can eliminate many of the tedious manual tasks typically associated with network maintenance, allowing IT administrators to improve efficiencies, increase performance, reduce risk and manage  growth. When choosing Network management software, IT organizations should look at a broad range of key criteria: functionality, features, architecture, integration, automation, reporting and cost. Only a thorough […]

Difference between SNMP RO and SNMP RW Community String

SNMP Protocol Simple Network Management Protocol (SNMP) is a popular protocol for network devices management. It is used for collecting information from, and configuring, network devices, such as servers, printers, hubs, switches, and routers on an Internet Protocol (IP) network. Very difficult to manage a large network with hundreds or thousands of nodes and it requires a large number staff to monitor every computer. SNMP, which is widely used in local area networks (LANs), lets you monitor network nodes from a management host. You can monitor network devices such as servers, workstations, printers, routers, bridges, and hubs, as well as services such as Dynamic Host Configuration Protocol (DHCP) or Windows Internet Name Service (WINS). Use SNMP management software to monitor any network device on which you install SNMP agent software. By default All Networking devices including Routers, Switches, Firewalls and other devices have inbuilt SNMP agent, we have to enable […]

How to Configure Syslog Server on Cisco Router for Logging

In this article I covered configuration steps you need to take on your Cisco Router or Switch to send messages to remote syslog server. Most of the Cisco devices use the syslog protocol to manage system logs and alerts. Syslog server is used to maintain log messages at centralized location, It improves the manageability of any size network and can decrease response times to resolve problems. Sending router log messages to a remote server also allows longer archiving of messages because Syslog server will have more storage than Cisco Router or Switch. Messages stored by syslog Server have permanence but Router doesn’t. When a router is reloaded or power cycled, the messages in its log are erased. In Syslog server there is a change view log messages even if Router power off. Note: Before configuring a Cisco device to send syslog messages, make sure that it is configured with the […]

How to Configure SNMP on Cisco IOS based Router or Switch

SNMP is an application-layer protocol that provides a message format for communication between SNMP managers and agents. The SNMP manager is the system used to control and monitors the activities of network hosts using SNMP; this is also called Network Management Station (NMS). This article explains how to configure Simple Network Management Protocol (SNMP) community strings on Cisco routers and Catalyst switches to enable SNMP agent. The configuration of SNMP on Cisco devices is very simple, and is handled from global configuration mode. We must define the relationship between the SNMP manger and Client. The command to enable SNMP client on the Cisco Router is snmp community, followed by the community name. This command also allows you to configure the SNMP agent as read only or for both read and write access. If not specified, by default it will be configured as read only. In this case, you configured community […]

How to Configure Netflow Data Export on Cisco Router or Switch

NetFlow is a Cisco IOS application that provides statistics on packets flowing through the Router. Using NetFlow you can export data (traffic statistics) to a remote workstation for processing. NetFlow is performed independently on each internetworking device, it does not need to be operational on each router in the network. Network Engineers can configure NetFlow selectively on a Routers or Router Interfaces to gain traffic statistics, Control or accounting benefits in Specific Network. NetFlow does consume additional memory and CPU resources; therefore, it is important to understand the resources required on your Router before enabling NetFlow. Prerequisites for NetFlow Configuration and Data Export on Router: 1. Configure IP routing on Router 2. If you want to configure NetFlow on  interfaces ,you must enable one of the following on Router Cisco Express Forwarding (CEF) Distributed CEF Fast switching Special notes on Netflow for specific Cisco IOS versions: 1. If your router is running […]

Install and Configure SNMP service in Windows XP, 2003 and Vista

The Simple Network Management Protocol (SNMP) is an application-layer protocol. SNMP can help network administrators manage network performance, find and solve network problems, and plan for network growth more easily. Note that you must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure. On Microsoft Windows, the SNMP service can be enabled and configured .When this is done, you will be allowed to retrieve information from the Microsoft Windows OS via SNMP. Proceed as follows:
