The QoS policy server examines the policy and decides it needs to know how to define the finance group. The policy server plugs the address range data into the policy instructions that it downloads to the network devices. This model covers most situations. For instance, a firewall may receive traffic from an unknown IP address. The policy server then queries the user registration service to verify the address, and based upon the answer, returns policy instructions to the firewall.
Managers define policies and behavior in policy servers based on business rules.
This capability greatly enhances network integrity, lowers management staff costs, and frees valuable staff time for other projects. Cisco Systems Inc. All rights reserved. Important Notices and Privacy Statement .
