Information Technology Reference
In-Depth Information
•
Graphical displays of Cisco products from a central location, giving network managers a complete
view of Cisco products without physically checking each device at remote sites
•
A continuously updated physical view of routers, hubs, switches, or access servers in a network,
regardless of physical location
•
Updated real-time monitoring and tracking of key information and data relating to device
performance, traffic, and usage, with metrics such as utilization percentage, frames transmitted and
received, errors, and a variety of other device-specific indicators
•
The capability to modify configurations such as trap, IP route, virtual LAN (VLAN), and bridge
configurations
Internetwork Performance Monitor
IPM
is a network management application that enables you to monitor the performance of multiprotocol
networks. IPM measures the response time and availability of IP networks on a hop-by-hop
(router-to-router) basis. It also measures response time between routers and the mainframe in Systems
Network Architecture (SNA) networks.
Use IPM to perform the following tasks:
•
Troubleshoot problems by checking the network latency between devices
•
Send Simple Network Management Protocol (SNMP) traps and SNA alerts when a user-configured
threshold is exceeded, when a connection is lost and re-established, or when a timeout occurs
•
Analyze potential problems before they occur by accumulating statistics, which are used to model
and predict future network topologies
•
Monitor response time between two network end points
The IPM product is composed of three parts: the IPM server, the IPM client application, and the response
time reporter (RTR) feature of the Cisco IOS software.
The TrafficDirector RMON Application
The
TrafficDirector
advanced packet filters let users monitor all seven layers of network traffic. Using
Cisco IOS embedded RMON agents and SwitchProbe standalone probes, managers can view
enterprise-wide network traffic from the link, network, transport, or application layers. The
TrafficDirector multilayer traffic summary provides a quick, high-level assessment of network loading
and protocol distributions. Network managers then “zoom in” on a specific segment, ring, switch port,
or trunk link and apply real-time analysis and diagnostic tools to view hosts, conversations, and packet
captures.
TrafficDirector threshold monitoring enables users to implement a proactive management environment.
First, thresholds for critical Management Information Base (MIB) variables are set within the RMON
agent. When these thresholds are exceeded, traps are sent to the appropriate management station to
notify the network administrator of an impending problem.
The VlanDirector Switch Management Application
The
VlanDirector
switch management application simplifies VLAN port assignment and offers other
management capabilities for VLANs. VlanDirector offers the following features for network
administrators:
