Displaying And Maintaining The Dhcp Server; Dhcp Server Configuration Examples - HP 5920 Series Configuration Manual

Step
2. Enable the DHCP server to
send BOOTP responses in
RFC 1048 format.

Displaying and maintaining the DHCP server

IMPORTANT:
A restart of the DHCP server or execution of the reset dhcp server ip-in-use command deletes all lease
information. The DHCP server denies any DHCP request for lease extension, and the client must request an
IP address again.
Execute display commands in any view and reset commands in user view.
Task
Display information about IP address conflicts.
Display information about lease-expired IP
addresses.
Display information about assignable IP
addresses.
Display information about assigned IP
addresses.
Display DHCP server statistics.
Display information about DHCP address
pools.
Clear information about IP address conflicts.
Clear information about lease-expired IP
addresses.
Clear information about assigned IP
addresses.
Clear DHCP server statistics.

DHCP server configuration examples

DHCP networking involves the following types:
The DHCP server and clients reside on the same subnet and exchange messages directly.
•
The DHCP server and clients are not on the same subnet and they communicate with each other
•
through a DHCP relay agent.
The DHCP server configuration for the two types is identical.

Remarks
By default, sending BOOTP responses in RFC
1048 format by the DHCP server is disabled.
This configuration takes effect only on the
BOOTP clients that request for a statically
bound address.
