Policies
C H A P T E R

Overview

The policy manager is responsible for maintaining a set of policy statements in a policy database and
communicating these policy statements to the applications that request them.
Policies are used by the routing protocol applications to control the advertisement, reception, and use of
routing information by the switch. Using policies, a set of routes can be selectively permitted (or
denied) based on their attributes, for advertisements in the routing domain. The routing protocol
application can also modify the attributes of the routing information, based on the policy statements.
Policies are also used by the access control list (ACL) application to perform packet filtering and
forwarding decisions on packets. The ACL application programs these policies into the packet filtering
hardware on the switch. Packets can be dropped, forwarded, moved to a different QoS profile, or
counted, based on the policy statements provided by the policy manager.
