Configuring The Dhcp Server To Send Bootp Responses In Rfc 1048 Format; Setting The Dscp Value For Dhcp Packets Sent By The Dhcp Server; Configuring Dhcp Binding Auto Backup - HP FlexNetwork MSR2003 Configuration Manual

Configuring the DHCP server to send BOOTP responses in
RFC 1048 format
Not all BOOTP clients can send requests that are compatible with RFC 1048. By default, the DHCP
server does not process the Vend field of RFC 1048-incompliant requests but copies the Vend field
into responses.
This function enables the DHCP server to fill the Vend field in RFC 1048-compliant format in DHCP
responses to RFC 1048-incompliant requests sent by BOOTP clients.
This function is effective for the BOOTP clients that request statically bound addresses.
To configure the DHCP server to send BOOTP responses in RFC 1048 format:
Step
1. Enter system view.
2. Enable the DHCP server to send
BOOTP responses in RFC 1048 format
to the RFC 1048-incompliant BOOTP
requests for statically bound addresses.
Setting the DSCP value for DHCP packets sent by
the DHCP server
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 server:
Step
1. Enter system view.
2. Set the DSCP value for DHCP
packets sent by the DHCP
server.

Configuring DHCP binding auto backup

The auto backup function saves bindings to a backup file and allows the DHCP server to download
the bindings from the backup file at the server reboot. The bindings include the lease bindings and
conflicted IP addresses. They cannot survive a reboot on the DHCP server.
The DHCP server does not provide services during the download process. If a connection error
occurs during the process and cannot be repaired in a short amount of time, you can terminate the
download operation. Manual interruption allows the DHCP server to provide services without waiting
for the connection to be repaired.
To configure DHCP binding auto backup:
Step
1. Enter system view.

such requests into the responses.
