Chapter 2 Monitoring the System

SNMP Basics

On the Cisco ICS 7750, the ICS System Manager software (the NMS) typically sends SNMP requests to a single IP address to access the SNMP MIBs of any system component. The SNMP agent can then respond to MIB-related queries being sent by the NMS. Similarly, if CiscoWorks2000 is the NMS, it uses the MIB variables to set device variables and poll devices on the network. You can then display the data that CiscoWorks2000 collects as a graph and analyze it to enhance network performance, to monitor traffic loads, or to troubleshoot problems. (See “Monitoring with CiscoWorks2000” on page 2-17 .)

As Figure 2-2shows, the SNMP agent gathers data from the MIB, which is the repository for information about device parameters and network data. The agent can send traps (see “Understanding Traps” on page 2-14) to the manager.
