¡
dhcp network add <option name> <value>
¡
dhcp network del <option name> <value>
(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 <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 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 <value>
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 <value>
dhcp max-lease-time <value>
These commands are similar to those described in the previous
paragraph, but their meaning is global.
4.3.8. dsl
This is a group of commands used to configure the DSL link.
Following options are available:
¡
dsl { fr | ppp | hdlc | raw } - selects the protocol used to send
®
data through the line - Frame Relay, synchronous PPP, Cisco
®
HDLC or raw HDLC. The Cisco HDLC is recommended if the
modem has to work in the bridge mode.
¡
dsl speed <value> [<second line> <third line> <fourth
line>] - sets the line throughput.
The value should be selected from 256-19456 kbps range with
256 kbps step.
17
Separate values selected from 64-4864 kbps range may also be
set for each of the lines. That possibility is useful if the lines differ
in their quality.
New throughput will be set after entering “dsl reset” command.
¡
dsl type { master | slave } - sets the modem type - master or
slave. New mode is set after entering “dsl reset” command.
Always one modem should be set as a master, while the other one
as a slave.
¡
dsl mod { auto | tcpam32 | tcpam16 | tcpam8 | tcpam 4
| pam16 | pam8 | pam4 | pam2 } -
selects line modulation.
The TCPAM32 modulation is recommended, as it is the most
efficient - the rest is available to provide compatibility with other
manufacturers’ devices.
Moreover TCPAM32 allows throughputs
from 256 kbps to 4864 kbps per line, while TCPAM16 - from 64
kbps to 2304 kbps.
The “auto” setting forces use of TCPAM32 for
speeds higher than or equal to 256 kbps per line and TCPAM16 for
lower rates.
¡
dsl reset - resets the DSL connection - the synchronization is
performed from the beginning
Entering “dsl” alone displays current settings.
4.3.9. exit, quit
The command closes the configuration session and disconects
from the modem.
4.3.10. fr
A group of commands used to configure the Frame Relay protocol
parameters. Following options are available:
¡
fr { ansi | q933a | cisco } - selects the LMI signaling: ANSI
®
T1.617 Annex D, ITU Q.933 Annex A or Cisco LMI
¡
fr t391 <value> - sets the T391 parameter, i.e. the number of
failed retries during the communication through the LMI, after
which the connection is considered as unusable
¡
fr n391 <value> - sets the N391 parameter, i.e. the time
between subsequent LMI retries
¡
fr debug { on | off} - enables and disables sending the Frame
