Some of the primary functions of network management
can be listed as follows:

It informs the operator of impending deterioration.
It provides easy alternative routing and work
arounds when deterioration or failure takes place.

The Case for Management
With proper management tools
and procedures in place, you
may already have the answer.
Consider some possibilities:
1. What configuration changes
were made overnight?
2. Have you received a device
fault notification indicating the
issue?
3. Have you detected a security
breach?
4. Has your performance baseline
predicted this behavior on an
increasingly congested network
link?
