What is Server Management? What is SNMP? What is Virtual Server Management? What is Agentless Network Monitoring? What Is Virtualization? Network management system Many businesses today, especially those operating in the IT landscape, deploy large-scale networks to meet their growing business requirements.
Challenges in the absence of a network management system NMS Below are some of the most prominent roadblocks that a business faces without a network management system: Network components are susceptible to performance degradation. Without a network management system, it's difficult to diagnose network faults, which impedes troubleshooting.
Businesses can expect frequent outages and prolonged downtime without a network management system. This can adversely impact operational continuity and productivity levels. RMON2 enables network administrators to continue their deployment of standards-based monitoring solutions to support mission-critical, server-based applications. Protocol Distribution Statistics for each protocol. Network Layer Host Statistics for each network layer address on the segment, ring, or port.
Network Layer Matrix Traffic statistics for pairs of network layer addresses. Application Layer Host Statistics by application layer protocol for each network address. Application Layer Matrix Traffic statistics by application layer protocol for pairs of network layer addresses. Address Mapping MAC-to-network layer address bindings. Configuration Group Agent capabilities and configurations. NetFlow The Cisco NetFlow feature allows detailed statistics of traffic flows to be collected for capacity planning, billing, and troubleshooting functions.
NetFlow can be configured on individual interfaces, providing information on traffic passing through those interfaces. The following types of information are part of the detailed traffic statistics:. NetFlow data gathered on network devices is exported to a collector machine. The collector performs functions such as reducing the volume of data filtering and aggregation , hierarchical data storage, and file system management.
Versions 2 through 4 and Version 6 were either not released or are not supported by FlowCollector. In all three versions, the datagram consists of a header and one or more flow records. The goal of security management is to control access to network resources according to local guidelines so that the network cannot be sabotaged intentionally or unintentionally. A security management subsystem, for example, can monitor users logging on to a network resource, refusing access to those who enter inappropriate access codes.
Security management is a very broad subject; therefore this area of the document only covers security as related to SNMP and basic device access security. Increasing Security on IP Networks. A good security management implementation starts with sound security policies and procedures in place.
It is important to create a platform-specific minimum configuration standard for all routers and switches that follow industry best practices for security and performance. There are various methods of controlling access on Cisco routers and catalyst switches. Some of these methods include:. TACACS is an authentication mechanism that is used to authenticate the identity of a device seeking remote access to a privileged database.
Authentication can be configured for login control or to authenticate individual commands. Authentication is the process of identifying users, including login and password dialog, challenge and response, and messaging support. Authentication is the way a user is identified prior to being allowed access to the router or switch.
There is a fundamental relationship between authentication and authorization. The more authorization privileges a user receives, the stronger the authentication should be. Authorization provides remote access control, including one-time authorization and authorization for each service that is requested by the user.
On a Cisco router, the authorization level range for users is 0 to 15 with 0 being the lowest level and 15 the highest. Accounting allows for the collecting and sending of security information used for billing, auditing, and reporting, such as user identities, start and stop times, and executed commands. Accounting enables network managers to track the services that users are accessing as well as the amount of network resources they are consuming. Refer to the Authentication, Authorization, and Accounting Commands document for more in-depth commands.
For more information on how to configure AAA to monitor and control access to the command-line interface on the Catalyst enterprise LAN switches, refer to the Controlling Access to the Switch Using Authentication, Authorization, and Accounting document. Proper security measures should be configured on network devices to prevent unauthorized access and change via SNMP. Community strings should follow the standard password guidelines for length, characters, and difficulty of guessing.
It is important to change the community strings from their public and private defaults. Cisco IOS and Cisco Catalyst software provides security features that ensure that only authorized management stations are allowed to perform changes on network devices. This feature limits the types of operations that a management station can have on a router.
The RO level only allows a management station to query the router data. It does not allow for configuration commands such as rebooting a router and shutting down interfaces to be performed. Only the RW privilege level can be used to perform such operations.
This feature limits specific information that can be retrieved from routers by management stations. The encryption and authentication features in SNMPv3 ensure high security in transporting packets to a management console.
The ACL can be applied on incoming or outgoing interfaces on routers. Syslog messages and SNMP traps are supported to notify a management system when a violation or unauthorized access occurs. A combination of the Cisco IOS security features can be used to manage routers and Catalyst switches. A security policy needs to be established that limits the number of management stations capable of accessing the switches and routers.
Accounting management is the process used to measure network utilization parameters so that individual or group users on the network can be regulated appropriately for the purposes of accounting or chargeback. Similar to performance management, the first step toward appropriate accounting management is to measure the utilization of all important network resources. Analysis of the data gathered through these methods provides insight into current usage patterns.
A usage-based accounting and billing system is an essential part of any service level agreement SLA. It provides both a practical way of defining obligations under an SLA and clear consequences for behavior outside the terms of the SLA. The data can be collected via probes or Cisco NetFlow. Cisco provides NetFlow Collector and NetFlow Analyzer applications for gathering and analyzing data from routers and Catalyst switches. Shareware applications such as cflowd are also used to gather NetFlow data.
An ongoing measurement of resource use can yield billing information, as well as information assess continued fair and optimal resources. Some commonly deployed accounting management solutions include:. Evident Software. NetFlow network flow is an input side-measurement technology that allows for capturing the data required for network planning, monitoring, and accounting applications.
Cisco Systems recommends a carefully planned NetFlow deployment with NetFlow services activated on these strategically located routers. NetFlow can be deployed incrementally interface by interface and strategically on well chosen routers , rather than deploying NetFlow on every router on the network. Cisco personnel will work with customers to determine on which key routers and key interfaces NetFlow should be activated based on the customer's traffic flow patterns, network topology, and architecture.
Understand application-driven data collection requirements. Accounting applications may only require originating and terminating router flow information whereas monitoring applications may require a more comprehensive data intensive end-to-end view. Understand the impact of network topology and routing policy on flow collection strategy. For example, avoid collecting duplicate flows by activating NetFlow on key aggregation routers where traffic originates or terminates and not on backbone routers or intermediate routers which would provide duplicate views of the same flow information.
Service providers in the transit carrier business carrying traffic neither originating nor terminating on their network may utilize NetFlow Export data for measuring transit traffic usage of network resources for accounting and billing purposes. Cisco IP accounting support provides basic IP accounting functions. By enabling IP accounting, users can see the number of bytes and packets switched through the Cisco IOS software on a source and destination IP address basis.
Only transit IP traffic is measured and only on an outbound basis. Traffic generated by the software or terminating in the software is not included in the accounting statistics. To maintain accurate accounting totals, the software maintains two accounting databases: an active and a check-pointed database. Identifying IP source addresses that violate IP access lists signals possible attempts to breach security.
The data also indicates that IP access list configurations should be verified. To make this feature available to users, enable IP accounting of access list violations using the ip accounting access-violations command. Users can then display the number of bytes and packets from a single source that attempted to breach security against the access list for the source destination pair. By default, IP accounting displays the number of packets that have passed access lists and were routed.
To enable IP accounting, use one of the following commands for each interface in interface configuration mode:. To configure other IP accounting functions, use one or more of the following commands in global configuration mode:.

Performance Monitoring, Measurement, and Reporting. Introduction The International Organization for Standardization ISO network management model defines five functional areas of network management.
Fault Management—Detect, isolate, notify, and correct faults encountered in the network. Accounting Management—Usage information of network resources. Fault Management The goal of fault management is to detect, log, notify users of, and to the extent possible automatically fix network problems to keep the network running effectively.
Network Management Platforms A network management platform deployed in the enterprise manages an infrastructure that consists of multivendor network elements. The following commonly available functions are included in a standard management platform: Network discovery Topology mapping of network elements Event handler Performance data collector and grapher Management data browser Network management platforms can be viewed as the main console for network operations in detecting faults in the infrastructure.
Troubleshooting Infrastructure Trivial File Transfer Protocol TFTP and system log syslog servers are crucial components of a troubleshooting infrastructure in network operations. Fault Detection and Notification The purpose of fault management is to detect, isolate, notify, and correct faults encountered in the network. Trap Description moduleUp The agent entity has detected that the moduleStatus object in this MIB has transitioned to the ok 2 state for one of its modules.
It can be one or more of the following values: voltage—A ciscoEnvMonVoltageNotification is sent if the voltage measured at a given test point is outside the normal range for the test point such as is at the warning, critical, or shutdown stage. Determine the following parameters for setting up thresholds and events.
Specify the trap sent RMON event when the threshold is reached using the following CLI commands The Cisco IOS commands are displayed in bold : rmon event 1 trap gateway description "High Broadcast on Ethernet 0" owner cisco rmon event 2 log description "normal broadcast received on ethernet 0" owner cisco Specify the thresholds and relevant parameters RMON alarm using the following CLI commands: rmon alarm 1 ifEntry.
Configuration Standards With an increasing number of network devices deployed, it is critical to be able to accurately identify the location of a network device. Configuration File Management When you add new configuration commands on existing network devices needs, you must verify the commands for integrity before actual implementation takes place. These functions can be accomplished with the configuration management tools in CiscoWorks Essentials: Push configuration files from the Essentials configuration archive to a device or multiple devices Pull the configuration from the device to the Essentials archive Extract the latest configuration from the archive and write it to a file Import configuration from a file and push the configuration to devices Compare the last two configurations in the Essentials archive Delete configurations older than a specified date or version from the archive Copy the startup configuration to the running configuration Inventory Management The discovery function of most network management platforms is intended to provide a dynamic listing of devices found in the network.
Software Management A successful upgrade of Cisco IOS images on network devices requires a detailed analysis of the requirements such as memory, boot ROM, microcode level, and so on. Performance Management Service Level Agreement A service level agreement SLA is a written agreement between a service provider and their customers on the expected performance level of network services.
Performance Monitoring, Measurement, and Reporting Different performance metrics at the interface, device, and protocol levels should be collected on a regular basis using SNMP. The following tables list the functions of the RMON groups. History Periodically samples and saves statistics group counters for later retrieval. Hosts Maintains statistics on each host device on the segment or port. Host Top N A user-defined subset report of the Hosts group, sorted by a statistical counter.
By returning only the results, management traffic is minimized. Traffic Matrix Maintains conversation statistics between hosts on the network. Packet Capture Manages buffers for packets captured by the Filter group for uploading to the management console. Security Management The goal of security management is to control access to network resources according to local guidelines so that the network cannot be sabotaged intentionally or unintentionally.
Detailed information on advanced security include: Increasing Security on IP Networks OpenSystems A good security management implementation starts with sound security policies and procedures in place. Authentication Authentication is the process of identifying users, including login and password dialog, challenge and response, and messaging support. Authorization Authorization provides remote access control, including one-time authorization and authorization for each service that is requested by the user.
Accounting Accounting allows for the collecting and sending of security information used for billing, auditing, and reporting, such as user identities, start and stop times, and executed commands. Use the console or Telnet keywords to enable authorization only for console port or Telnet connection attempts. SNMP View This feature limits specific information that can be retrieved from routers by management stations. Accounting Management Accounting management is the process used to measure network utilization parameters so that individual or group users on the network can be regulated appropriately for the purposes of accounting or chargeback.
Some commonly deployed accounting management solutions include: Evident Software NetFlow Activation and Data Collection Strategy NetFlow network flow is an input side-measurement technology that allows for capturing the data required for network planning, monitoring, and accounting applications.
