Configure The Dhcp Server To Ignore Bootp Requests; Configuring The Dhcp Server To Send Bootp Responses In Rfc 1048 Format; Disabling Option 60 Encapsulation In Dhcp Replies - HPE FlexNetwork HSR6800 Configuration Manual

Step
2. Enable the DHCP server
to broadcast all
responses.

Configure the DHCP server to ignore BOOTP requests

The lease duration of the IP addresses obtained by the BOOTP clients is unlimited. For some
scenarios that do not allow unlimited leases, you can configure the DHCP server to ignore BOOTP
requests.
To configure the DHCP server to ignore BOOTP requests:
Step
1. Enter system view.
2. Configure the DHCP server to
ignore BOOTP requests.
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 feature 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 feature 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.

Disabling Option 60 encapsulation in DHCP replies

If one or more DHCP clients cannot resolve Option 60, disable the DHCP server from encapsulating
Option 60 in DHCP replies. If you do not disable the capability, the DHCP server encapsulates
Option 60 in a DHCP reply in the following situations:
•
The received DHCP packet contains Option 60.
•
Option 60 is configured for the address pool.
To disable the DHCP server from encapsulating Option 60 in DHCP replies:

Remarks
By default, the DHCP server reads
the broadcast flag to decide
whether to broadcast or unicast a
response.
Remarks
N/A
By default, the DHCP server
processes BOOTP requests.
Remarks
N/A
By default, the DHCP server
directly copies the Vend field of
such requests into the responses.
