Step
2. Create a DHCP address
pool and enter its view.
3. Specify gateway addresses
for the clients matching the
DHCP address pool.
4. Specify DHCP servers for
the DHCP address pool.
Specifying the DHCP relay agent address to be
padded to DHCP requests
Perform this task to specify the DHCP relay agent address to be padded to the giaddr field of DHCP
requests. If you do not specify a DHCP relay agent address, the primary IP address of the DHCP
relay interface is padded to the giaddr field of DHCP requests.
To specify the DHCP relay agent address to be padded to DHCP requests:
Step
1. Enter system view.
2. Enter interface view.
3. Specify the DHCP relay agent
address to be padded to

address and sends a RELEASE message to the DHCP server. The feature does not function if an
ARP entry is manually deleted.
To enable client offline detection on the DHCP relay agent:
Step
1. Enter system view.
