Assigning ISG Subscriber IP Addresses Using DHCP
Before you perform this task, you should understand the following concepts:
•
ISG Subscriber IP Address Assignment Using DHCP, page 24
(required)
To assign ISG subscriber IP addresses using DHCP, perform the following tasks:
•
Configuring an ISG Interface for Dynamic DHCP Class Association, page 25
(required)
•
Configuring a DHCP Class in a Service Policy Map, page 26
(required)
•
Configuring a DHCP Class in a Service Profile or User Profile on the AAA Server, page 27
(required)
ISG Subscriber IP Address Assignment Using DHCP
When ISG is in the path of DHCP requests (as either a DHCP server or a DHCP relay), ISG can influence
the IP address pool and DHCP server that are used to assign subscriber IP addresses. To enable ISG to
influence the IP addresses assigned to subscribers, you associate a DHCP address pool class with an
address domain. The DHCP address pool class must also be configured in a service policy map, service
profile, or user profile, which is associated with a subscriber. When a DHCP request is received from a
subscriber, DHCP uses the address pool class that is associated with the subscriber to determine which
DHCP address pool should be used to service the request. As a result, on a per-request basis, an IP
address is provided by the local DHCP server or relayed to a remote DHCP server that is defined in the
selected pool.
Command or Action
Purpose
Step 1
show ip subscriber [dangling seconds | detail |
ip ip-address | mac mac-address | vrf vrf-name
[dangling seconds | detail | ip ip-address]]
Example:
Router# show ip subscriber ip 10.10.10.10
(Optional) Displays information about ISG subscriber IP
sessions.
•
Use this command to display the IP sessions on ISG.
Step 2
clear ip subscriber [dangling seconds | ip
ip-address | mac mac-address | vrf vrf-name
[dangling seconds | ip ip-address]]
Example:
Router# clear ip subscriber ip 10.10.10.10
Clears ISG IP subscriber sessions.
