dhcp add relay [

forwarded, when the Relay Agent mode is enabled. The
parameter is optional - its default value is 67:
dhcp add relay 192.168.0.3
4.3.7.5. dhcp del
The command deletes a network, subnet, address range, etc.
¡
dhcp del network
¡
dhcp del subnet
¡
dhcp del host
The commands above delete, respectively, a network, an IP
subnet or a host (a static IP-MAC connection) with given name.
¡
dhcp del relay
Deletes a DHCP server address used in the Relay Agent mode.
¡
dhcp del range
Deletes an IP address range assigned to the network stations.
¡
dhcp del option
Deletes a global option. Besides the option name, its value should
also be given, because some options may have more than one value
(e.g. domain name servers, routers, etc.).
4.3.7.6. dhcp rename
The command changes the name of a network, subnet or host:
¡
dhcp rename network
¡
dhcp rename subnet
¡
dhcp rename host
4.3.7.7. dhcp network/subnet/host
The command adds or deletes an option within a specified group -
network, subnet or host. It has two forms:
17
¡
dhcp network add
¡
dhcp network del
(instead of „network”, a „subnet” or „host” may be given; options
are described in 4.3.7.4), e.g. :
dhcp network add domain-name tahoe-group.com
Options are valid only for a given network, subnet or host.
Moreover two other parameters can be set:
¡
dhcp network default-lease-time
Sets the time (in second), for which the IP address is assigned to
the station. After that time the station must inform the DHCP server that
it still uses that address. Otherwise the address will be considered as
unused. This timeout prevents blocking an IP address when a station is
switched off without releasing that address.
¡
dhcp network max-lease-time
A station may request other lease time - the negotiated time may
not be higher than this setting.
4.3.7.8. dhcp default-lease-time
dhcp max-lease-time
These commands are similar to those described in the previous
paragraph, but their meaning is global.
4.3.8.
dsl

Following options are available:
¡
dsl { fr | ppp | hdlc } - selects the protocol used to send data
®
through the line - Frame Relay, synchronous PPP or Cisco HDLC.
®
The Cisco HDLC is recommended if the modem has to work in
the bridge mode.
¡
dsl speed
throughput.
In case of Tahoe 681 modem the value should be selected from
64-4864 kbps range with 64 kbps step.
In Tahoe 682 modems the throughput may be set in two ways -
either by giving the total rate from 128-9728 kbps range, or by
