Configuring Dhcp Packet Rate Limit On A Dhcp Relay Interface; Specifying The Dhcp Relay Agent Address For The Giaddr Field; Manually Specifying The Dhcp Relay Agent Address For The Giaddr Field; Configuring Smart Relay To Specify The Dhcp Relay Agent Address For The Giaddr Field - H3C SR8800-F Configuration Manual

Configuring DHCP packet rate limit on a DHCP
relay interface
IMPORTANT:
The feature is available only on the CSPEX cards.
This feature enables the DHCP relay interface to discard DHCP packets that exceed the maximum
rate.
To configure DHCP packet rate limit:
Step
1. Enter system view.
2. Enter interface view.
3. Enable DHCP packet rate limit
on the interface and set the
limit value.
Specifying the DHCP relay agent address for the
giaddr field
Manually specifying the DHCP relay agent address for the
giaddr field
This task allows you to specify the IP addresses to be encapsulated to the giaddr field of the DHCP
requests. If you do not specify any DHCP relay agent address, the primary IP address of the DHCP
relay interface is encapsulated to the giaddr field of DHCP requests.
To manually specify the DHCP relay agent address for the giaddr field:
Step
1. Enter system view.
2. Enter interface view.
3. Specify the DHCP relay agent
address to be encapsulated to
DHCP requests.
Configuring smart relay to specify the DHCP relay agent
address for the giaddr field
The DHCP smart relay feature allows the DHCP relay agent to encapsulate secondary IP addresses
when the DHCP server does not send back a DHCP-OFFER message.
