Configuring SNMP
• Read-write—Gives read and write access to authorized management stations to all objects in the
MIB, but does not allow access to the community strings
Using SNMP to Access MIB Variables
An example of an NMS is the CiscoWorks network management software. CiscoWorks 2000 software
uses the access point MIB variables to set device variables and to poll devices on the network for specific
information. The results of a poll can be displayed as a graph and analyzed to troubleshoot
internetworking problems, increase network performance, verify the configuration of devices, monitor
traffic loads, and more.
As shown in Figure 18-1, the SNMP agent gathers data from the MIB. The agent can send traps
(notification of certain events) to the SNMP manager, which receives and processes the traps. Traps are
messages alerting the SNMP manager to a condition on the network such as improper user
authentication, restarts, link status (up or down), MAC address tracking, and so forth. The SNMP agent
also responds to MIB-related queries sent by the SNMP manager in get-request, get-next-request, and
set-request format.

For information on supported MIBs and how to access them, see Appendix C, “Supported MIBs.”
