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.
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.
