Introduction to Wireless LAN Analysis
foundation upon which to manage the network, it is important to have
some idea of how the network is running. To do this, you must go
through a process called a baseline. By following the baseline process,
you can obtain the following information:
Gain valuable information on the health of the hardware and
software
Determine the current utilization of network resources
Make accurate decisions about network alarm thresholds
Identify current network problems
Predict future problems
By performing a baseline on a regular basis, you can find out the
current state and extrapolate when failures will occur and prepare for
them in advance. This also helps you to make more informed decisions
about when, where, and how to spend budget money on network
upgrades.
Why a Baseline?
A baseline process helps you to identify and properly plan for critical
resource limitation issues in the network. These issues can be divided
into two groups, each described as either “control plane” resources or
“data plane” resources. Control plane resources are unique to the
specific platform and device and can be impacted by a number of issues
including:
Data link utilization
Features enabled
Network design
Control plane resources include parameters such as:
CPU utilization
Memory utilization
Buffer utilization
