1
Set the DHCP Spoofing parameter to Yes to enable any DHCP service. This
parameter, which was included in earlier versions of the Ascend software,
now has a different meaning. It must be Yes for any DHCP service to be
enabled. If it is set to No, other settings in this menu are ignored.
2
Set the DHCP PNP Enabled parameter to Yes to enable Plug and Plug.
Setting this parameter to Yes and DHCP Spoofing set to Yes is all that is
required to enable Plug and Play support.
3
Renewal Time specifies how long a DHCP IP address lives before it needs to
be renewed. It applies to DHCP spoofed addresses and DHCP server replies.
If the host renews the address before it expires, the Pipeline provides the
same address. Plug and Play addresses always expire in 60 seconds.
4
Become Default Router is an option you can set to advertise the address of
your Pipeline as the default router for all DHCP request packets.
5
Dial If Link Down is used with DHCP spoofing in conjunction with BOOTP
Relay. This parameter applies when both DHCP spoofing and BOOTP relay
are enabled. If no wide area network links are active, the Pipeline performs
DHCP spoofing. When set to Yes, as soon as the dialed link is established,
the Pipeline stops DHCP spoofing and acts as a BOOTP relay agent.
6
Set Always Spoof as follows:
–
Yes enables the DHCP server.
A DHCP server always supplies an IP
address for every request, until all IP addresses are exhausted.
–
No enables DHCP spoofing.
DHCP spoofing only supplies an IP
address for a single host on the network. It does not respond to all
requests.
