Tahoe 4681 (4-port G.shdsl.bis/FastEthernet modem card)
dhcp { network | subnet | host }
The command adds or deletes an option within a specified group – network, subnet or host. To
add an option to a network type:
dhcp network
<
name
>
add
<
option name
> <
value>
To remove an option:
dhcp network
<
name
>
del
<
option name
> <
value
>
Similarily subnet and host options may be added or deleted by replacing the network keyword
by subnet or host. Example:
Tahoe> dhcp subnet local add domain-name tahoe-group.com
Options are valid only for a given network, subnet or host. The option list is available in the dhcp
add command description above.
Besides these standard options two other parameters can be set:
dhcp network default-lease-time < value >
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 ad-
dress will be considered as unused. This time-out prevents blocking an IP address when a
station is switched off without releasing that address.
dhcp network max-lease-time < value >
A station may request a lease time other than the default value – the negotiated time may not
be higher than this setting.
dhcp default-lease-time <value>
dhcp max-lease-time <value>
These commands are similar to those described in the previous paragraph, but their meaning is
global.
