Intelligent Services Gateway Features Roadmap
4
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:
DHCP Proxy
This feature enables ISG to dynamically interact with
DHCP and apply policies that influence the IP
addresses that DHCP assigns to subscribers.
Configuring ISG Access
for IP Subscriber
Sessions
Cisco IOS XE
Release 2.2
ISG:Policy Control:
ISG-SCE Control Bus
This feature enables integration of an ISG device with
an SCE device at the control plane level, allowing the
two devices to work as one when policies are applied to
a subscriber session.

Integration with SCE
Cisco IOS XE
Release 2.2
ISG:Policy Control:
Multidimensional
Identity per Session
ISG control policies provide a flexible way to collect
pieces of subscriber identity during session
establishment. Control policies also allow session
policy to be applied iteratively as more elements of
identity become available to the system.

Policies
Cisco IOS XE
Release 2.2
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.

Policies
Cisco IOS XE
Release 2.2
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.

ISG:Policy Control:
Policy Server: CoA
This feature provides ISG support for the RADIUS
Change of Authorization (CoA) extension, which
facilitates dynamic authorization.

ASCII Command Code
Support
This feature enables ISG to receive ASCII command
codes for Account Logon, Account Logoff, Service
Logon, Service Logoff, and Account Status queries and
to perform the required functionality based on the
command code.
