operating commands and includes the following sections:

Performance Overview
Con®guring performance allows you to monitor your CPU load. In the idle (non-work
load) state, performance re¯ects operations that the router continuously performs as
a part of managing external interfaces. The CPU load registered in the idle state is
dependent upon:
v Number of protocols running.
v Number of interfaces/cards installed.
v Type of interfaces installed.
The performance function can be used as a tool for trend analysis, bottleneck
evaluation, and capacity planning. By collecting the CPU utilization information on
the router, a network manager can monitor:
v CPU load versus time of day.
v CPU load versus location of the router in the network.
v CPU load versus traffic throughput.
v CPU load versus user load (for example: TN3270 sessions, ISDN dial in clients)
Performance Reporting Accuracy
If you request a performance analysis when the 2210 ®rst comes online, you will
see values that re¯ect an initialization state that has little or no network traffic, so it
is of little use in helping to balance your network load.
It is best to use performance reports that are generated under normal loads after
approximately 2 minutes of operation.

Accessing the Performance Con®guration Environment

Use the following procedure to access the Performance monitor con®guration process.

1.At the OPCON prompt, enter talk 6. (For more detail on this command, see ªChapter 5. The Con®guration Process (CONFIG - Talk 6) and Commandsº on page 39 .) For example:
