Dial MIBs and OIDs Used in the Case Study

This section describes the MIBs and OIDs used to manage the dial Internet access service in the case study.

See the following tables and choose the variables you want to use in your network. Explore the OIDs and determine whether to poll and graph the results on a regular basis.

To explore the MIBs and OIDs, use UCD-SNMP. For more information, see the “Task 2— Exploring SNMP Capabilities by Using UCD-SNMP” section on page 45.

To graph the trending statistics for a specific OID, use Multi Router Traffic Grapher (MRTG). For more information, see the “Task 3—Using MRTG to Monitor and Graph Traffic Loads” section on page 53.

Caution Be cautious when polling network elements. Polling OIDs that retrieve large amounts of data can cause CPU problems on a Cisco IOS device. For example, do not get the ARP table, walk large portions of a MIB tree, poll the wrong OID too frequently, or get statistics that have an entry for every interface. For example, a Cisco 7200 may have 10 interfaces; whereas, a Cisco AS5800 may have 3,000 interfaces.
