Configuring ISG Subscriber Services
How to Configure ISG Services on the Router
8
Configuring an ISG Service with a Traffic Policy
An ISG traffic policy contains a traffic class and one or more ISG features. The traffic class defines the
traffic to which the features will be applied. Perform the following tasks to configure an ISG service with
a traffic policy on the router:
•
Defining an ISG Traffic Class Map, page 8
• Configuring an ISG Service Policy Map with a Traffic Policy, page 9
Defining an ISG Traffic Class Map
Perform this task to configure a traffic class map. A traffic class map usually specifies an access control
list (ACL) that classifies the flow and the direction of traffic to which the ACL applies (inbound or
outbound).
Note You can also configure an empty traffic class map, that is, a traffic class map that does not specify an
access list, in order to configure a service with a traffic policy that applies to all session traffic.
Prerequisites
This task assumes that access control lists (ACLs) have been configured for classifying traffic.
SUMMARY STEPS
1. enable
2.
configure terminal
3.
class-map type traffic match-any class-map-name
4. match access-group input {access-list-number | name access-list-name}
5. match access-group output {access-list-number | name access-list-name}
6. exit
Step 12
sg-service-group service-group-name
Example:
Router(config-service-policymap)#
sg-service-group group1
Associates the service with a specified service group.
Step 13
sg-service-type {primary | secondary}
Example:
Router(config-service-policymap)#
sg-service-type primary
Defines the service as a primary or secondary service.
• A primary service is a service that contains a
network-forwarding policy. A service must be defined
as a primary service by using the sg-service-type
primary command. Any service that is not a primary
service is defined as a secondary service by default.
