3. show ip subscriber [dangling seconds | detail | ip ip-address | mac mac-address | vrf vrf-name
[dangling seconds | detail | ip ip-address]]
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
policy-map type service policy-map-name
Example:
Router(config)# policy-map type service
service1
Creates or modifies a service policy map, which is used to
define an ISG service, and enters service policy-map
configuration mode.
Step 4
ip vrf forwarding name-of-vrf
Example:
Router(config-service-policymap)# ip vrf
forwarding vrf2
Associates the service with a VRF.
Step 5
sg-service-type primary
Example:
Router(config-service-policymap)#
sg-service-type primary
Defines the service as a primary service.
• A primary service is a service that contains a
network-forwarding policy. A primary 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.
Step 6
sg-service-group service-group-name
Example:
Router(config-service-policymap)#
sg-service-group group1
(Optional) Associates an ISG service with a service group.
• A service group is a grouping of services that may be
active simultaneously for a given session. Typically, a
service group includes one primary service and one or
more secondary services.
