Configuring ISG Access for IP Subscriber Sessions
Configuration Examples for ISG Access for IP Subscriber Sessions
36
DHCP-Initiated Session Recovery: Example
The following example configures an ISG policy that applies a service called “FIRST-SERVICE” upon
session restart for subscribers belonging to the VRF “FIRST”.
class-map type control TEST
match vrf FIRST
policy-map type control GLOBAL
class type control TEST event session-restart
1 service-policy type service name FIRST-SERVICE
ISG Interface with DHCP Class-Aware Capability: Example
In the following example, GigabitEthernet interface 1/0/0.400 is configured with DHCP class-aware
functionality, which enables ISG to influence DHCP IP address assignment. If the service
“SERVICE_DHCP” is activated, the DHCP pool “DHCP_POOL2” is used for address assignment.
Otherwise, the default pool “DHCP_POOL1” is used.
