Setting The Dscp Value For Dhcp Packets Sent By The Dhcp Relay Agent; Enabling Dhcp Server Proxy On A Dhcp Relay Agent - HP FlexNetwork MSR2003 Configuration Manual

Step
4. (Optional.) Configure the strategy
for handling DHCP requests that
contain Option 82.
5. (Optional.) Configure the padding
mode and padding format for the
Circuit ID sub-option.
6. (Optional.) Configure the padding
mode and padding format for the
Remote ID sub-option.
Setting the DSCP value for DHCP packets sent by
the DHCP relay agent
The DSCP value of a packet specifies the priority level of the packet and affects the transmission
priority of the packet.
To set the DSCP value for DHCP packets sent by the DHCP relay agent:
Step
1. Enter system view.
2. Set the DSCP value for DHCP
packets sent by the DHCP
relay agent.
Enabling DHCP server proxy on a DHCP relay
agent
The DHCP server proxy feature isolates DHCP servers from DHCP clients and protects DHCP
servers against attacks.
Upon receiving a response from the server, the DHCP server proxy modifies the server's IP address
as the relay interface's IP address before sending out the response. The DHCP client takes the
DHCP relay agent as the DHCP server.
To configure DHCP server proxy on a DHCP relay agent:
Step
1. Enter system view.
2. Enter interface view.
3. Enable DHCP relay agent and
DHCP server proxy on the
interface.
