Usage guidelines
Not all BOOTP clients can send requests compliant 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.
Use this command to enable the DHCP server to fill in the Vend field using the RFC 1048-compliant
format in DHCP responses to RFC 1048-incompliant requests sent by BOOTP clients that request statically
bound addresses.
Examples
# Enable the DHCP server to send BOOTP responses in RFC 1048 format upon receiving BOOTP
requests incompliant with RFC 1048.

Parameters
start-ip-address: Specifies the start IP address.
end-ip-address: Specifies the end IP address, which cannot be lower than the start-ip-address. If the
argument is not specified, only the start-ip-address is excluded from dynamic allocation. If it is specified,
the IP addresses from start-ip-address through end-ip-address are all excluded from dynamic allocation.
Usage guidelines
The IP addresses of some devices such as the gateway and FTP server cannot be assigned to clients. Use
this command to exclude such addresses from dynamic allocation.
You can exclude multiple IP address ranges from dynamic allocation.
