Cisco IOS XE
Release 2.2
ISG:Policy Control:
Cisco Policy Language
ISG control policies are a structured replacement for
feature-specific configuration commands and allow
configurable functionality to be expressed in terms of
an event, a condition, and an action. Control policies
provide an intuitive and extensible framework, with a
consistent set of CLI commands, for specifying system
behavior. The ISG policy language is aligned with the
Cisco Common Classification Policy Language
(C3PL).

ISG:Policy Control:
Multidimensional

policy to be applied iteratively as more elements of
identity become available to the system.

ISG:Policy Control:
Policy: Domain Based
(Auto-domain, Proxy)
ISG control policies manage the primary services and
rules used to enforce particular contracts. Polices can be
configured to interpret the domain as a request to
activate the service associated with that domain name,
allowing users to automatically receive services in
accordance with the domain that they are attempting to
connect.

ISG:Policy Control:
Policy: Triggers
ISG control policies can be configured with time-based,
volume-based, and duration-based policy triggers.
Time-based triggers use an internal clock, allowing
policies to be applied at specific times. Volume-based
triggers are based on packet count; when the packet
count reaches a specified value, the specified policy is
applied. Duration-based triggers are based on an
internal timer. Upon expiration of the timer, the
specified policy is applied.
