DHCP Server Configuration
Use this notebook tab to set server parameters not set
elsewhere.
Fields and check boxes include:
- Client support
-
- Support BootP clients
- Check this box to provide DHCP server support for BootP clients
(supportBootp keyword). If this box is not checked, the server will not
respond to requests from BootP clients.
If the server previously supported BootP clients and has been reconfigured
to not support BootP clients, the address binding for any BootP client that
was established before the reconfiguration will be maintained until the BootP
client sends another request (when it is restarting). At that time, the
server will not respond and the binding will be removed.
- Unlisted client support
- Use these radio buttons to identify which unlisted clients will be
supported:
- Support unlisted DHCP clients
- If the box is checked, the server responds only to requests from any DHCP
client (supportUnlistedClients keyword DHCP).
- Support unlisted BootP clients
- If the box is checked, the server responds only to requests from any BootP
client (supportUnlistedClients keyword BOOTP).
- Support both unlisted DHCP and BootP clients
- If the box is checked, the server responds to requests from any DHCP
client or BootP (supportUnlistedClients keyword BOTH).
- Support listed clients only
- If the box is checked, the server responds only to requests from DHCP or
BootP clients (supportUnlistedClients keyword NO) specifically listed (by
client ID) in the configuration file.
- Broadcasting for Bridged Token Ring Environments
-
- All routes broadcast
- Check this box to have the DHCP server broadcast all replies
(allRoutesBroadcast keyword).
- Single route broadcast
- Check this box to have the DHCP server use the routing information field
on the incoming packet from a DHCP client to broadcast replies.
Otherwise, single route broadcast is used to send replies. For example,
use single-route broadcast for bridged token-ring networks that implement a
spanning-tree algorithm.
- Match user class to vendor class
-
- Serve user class options when the same vendor class identified is passed
from the client.
- When this box is checked, the DHCP server serves user class options when a
user class matches the vendor class passed by the client. Otherwise,
the DHCP server serves user class options only if the client passes the user
class option in its request.
