Example

! Set the DDR auto-dial interval to 60 seconds


3/29




1-2

Quidway(config-if-Serial0)# dialer autodial-interval 60

Related Command

dialer map

1.2 dialer callback-server

To implement PPP callback, use the dialer callback-servercommand. It is configured

at the Server, and is used for DDR to determine if callback to the remote isimplemented via the callback-dialstringconfigured by the user in the usercommand orif it is implemented via the dialermap configured by the user. To return to the default,use the no form of this command.

dialer callback-server{username [dialstring] | dialstring [username]}

no dialer callback-server

Syntax Description

username Callback is implemented via dialer map configured by the user; in the

corresponding dialermap, the name option must be configured.

dialstring Callback is made to the remote end through callback-dialstringin user.

Default

no dialer callback-server.

Command Mode


Usage Guideline

This command must be configured when PPP callback is applied.

When the username and dialstring parameters are applied at the same time, the router

should call back according to the requirement of the first parameter. When the callbackfails, then try the second parameter for callback.

Example

! Configure the remote username, and set a user matching this username for callback

Quidway(config)# user quidwayb password 0 quidwayb

Quidway(config-if-Serial0)# dialer map ip 100.1.1.2 name quidwayb 8810052

Quidway(config-if-Serial0)# dialer callback-server username

Quidway(config-if-Serial0)# ppp authentication pap

Quidway(config-if-Serial0)# ppp callback accept


4/29




1-3

Related Command

dialer callback accept, ppp authentication, username name callback-dialstring

1.3 dialer caller

To decide if callback is implemented according to the input number in the ISDN caller

ID callback application, use the dialer callercommand. To return to the default, usethe no form of this command.

dialer callerremote-number[callback]

no dialer callerremote-number[callback]

Syntax Description

remote-number Character string for matching the remote incoming number. * is usedto stand for any character.

Default

no dialer caller.

Command Mode


Example

! Set callback to the user whose caller number is 8810152

Quidway(config-if-Bri0)# dialer map ip 100.1.1.2 8810152

Quidway(config-if-Bri0)# dialer caller 8810152 callback

1.4 dialer enable-timeout

To set the time interval for the next call when a call completes or fails, use the dialerenable-timeout command. To return to the default, use the no form of this command.

dialer enable-timeoutseconds

no dialer enable-timeout

Syntax Description

seconds Time interval for the next call attempt in the second, ranging 0 to 65535.

Default

Default DDR call time interval: 20 seconds.

Command Mode



5/29




1-4

Usage Guideline

If the link keeps busy or fails to be connected when calling the remote end, set this

interval before the next call so as to avoid overload on the switching equipment.

Example

! Set the DDR call duration to 5 seconds

Quidway(config-if-Serial0)# dialer enable-timeout 5

Command Mode

dialer in-band

1.5 dialer fast-idle

To set a new idle time for the interface when call competition occurs at an interface, use

the dialer fast-idle command. To return to the default, use the no form of thiscommand.

dialer fast-idle seconds

no dialer fast-idle

Syntax Description

seconds Fast idle time value in the second, ranging 1 to 65535.

Default

Fast idle time: 20 seconds.

Command Mode


Usage Guideline

Normally, when a link is set up, idle-timeout will play a decisive rule. But if there is a callto another destination address, then DDR uses fast-idle in the place of idle-timeout.

Example

! Set idle-timeout to 50 seconds, and fast-idle to 10 seconds.

Quidway(config-if-Serial0)# dialer idle-timeout 50

Quidway(config-if-Serial0)# dialer fast-idle 10

Related Command

dialer idle-timeout, dialer in-band


6/29




1-5

1.6 dialer hold-queue

To set the number of interesting packets in the buffer before a link is set up, use the

dialer hold-queue command. To return to the default, use the no form of thiscommand.

dialer hold-queuepackets

no dialer hold-queue

Syntax Description

packets Number of packets that can be buffered at this interface, ranging 0 to 100.

Default

Default number of buffered packets: 0.

Command Mode


Usage Guideline

When setting up a link, interesting packets are saved to the queue, whose size isdecided by packets. If the size is 0, then data packets will be dumped.

Example

! Set the number of packets that can be buffered at Serial 1 to 10

Quidway(config-if-Serial1)# dialer hold-queue 10

Related Command

dialer-group, dialer in-band

1.7 dialer idle-timeout

To set the idle time for the interface after setting up a call at an interface, use the dialeridle-timeout command. To return to the default, use the no form of this command.

dialer idle-timeout seconds

no dialer idle-timeout

Syntax Description

seconds Idle timeout in second, ranging 0 to 65535.

Default

Timeout: 120 seconds.


7/29




1-6

Command Mode


Usage Guideline

When a link is set up, idle-timeout will play a decisive role. If no interesting packets are

sent from this link in a set time, DDR will suspend this link. If idle-timeout is set to 0,then when a corresponding link is set up, it will never be suspended (even if nointeresting data are sent from this link).

Example

! Set idle-timeout at Serial 0 to 50 seconds

Quidway(config-if-Serial0)# dialer idle-timeout 50

Related Command

dialer fast-idle, dialer-group

1.8 dialer in-band

To enable the legacy DDR configuration, use the dialer in-band command. To return to

the default, use the no form of this command.

dialer in-band

nodialer in-band

Default

Legacy DDR enabled at the ISDN interface; legacy DDR disabled at other interfaces.

Command Mode


Usage Guideline

If the user adopts the legacy DDR configuration, this command must be used to enable

it.

Example

! Enable legacy DDR

Quidway(config-if-Serial0)# dialer in-band

Related Command

dialer map, dialer string, dialer rotary-group


8/29




1-7

1.9 dialer isdn-leased

To configure the ISDN B channel connected to the leased line, includingBRI and PRI,

use the dialer isdn-leased command. To return to the default, use the no form of thiscommand.

dialer isdn-leased number

no dialer isdn-leased number

Syntax Description

number ISDN B channel number for the leased line. Ranging 1 to 2 in BRI interface,

ranging 0 to 30 in PRI interface.

Default

No ISDN B channel connected to the leased line is configured.

Command Mode


Usage Guideline

Any ISDN B channel can be configured to be the leased line, and this configuration will

not influence the settings of other B channels.

Example

! Set the first B channel of BRI0 as the leased line

Quidway(config-if-Bri0)# dialer isdn-leased 1

1.10 dialer load-threshold

To start another link to call the same destination address when the traffic on a link at the

DDR interface exceeds the set percentage (threshold), use the dialer load-thresholdcommand. To return to the default, use the no form of this command.

dialer load-threshold load[ either| inbound | outbound ]

no dialer load-threshold

Syntax Description

load Percentage of actual traffic over the bandwidth of the link, ranging 0 to 99.

either Only counting the larger one of inbound and outbound traffic when calculatingactual traffics.

inbound Only counting the inbound traffic when calculating actual traffics.

outbound Only counting the outbound traffic when calculating actual traffics.


9/29




1-8

Default

loadis 0, that is, no traffic control is started.

Command Mode


Usage Guideline

All of the usable links will be started when loadis 0.

When the ratio of traffic on a link to bandwidth on a DDR interface link exceeds a set

threshold, a second link is started to implement MP bounding with the first one. When

the ratio of traffic on two links to bandwidth exceeds a set threshold, a third link isstarted, and so on. On the contrary, when the ratio of the traffic on N (N is an integergreater than or equal to 2) links to bandwidth of N-1 links less than a set threshold, turn

off one link. In Legacy DDR, this command can be used on interface corresponding toDialer rotary-group (including ISDN BRI/PRI interface and Dialer interface). In DialerProfile, this command can only be used on Dialer interface. In addition, this commandshould be used together with ppp multilink.

Example

! Set the traffic threshold of Dialer 1 to 80%.

Quidway(config-if-Dialer1)# dialer load-threshold 80

Related Command

dialer rotary-group, dialer remote-name, ppp multilink

1.11 dialer map

To enable a DDR interface to call one or multiple destination addresses or receive calls

from multiple remote addresses, use the dialer map command. To return to the default,use the no form of this command.

dialer map protocol next-hop-address [name hostname] [broadcast] [dial-string

[:isdn-subaddress]] [autodial] [lin logic-channel-number]

automatically attempt to dial via this dialer map every time interval, which is configuredthrough the dialer autodial-interval command; default: 300 seconds.

logic-channel-numberLogic channel number at a backup center.

Default

no dialer map.

Command Mode


Usage Guideline

To originate a call only, use the dialer-stringparameter.

If use the key word name, it is necessary to configure PPP authentication. A dialer port

can be configured with multiple dialer map, and a destination address can also beconfigured with multiple dialer map.

& Note:

If no dialer-group command, then DDR will not dial.

Example

! Set a dialer map at Serial 0

Quidway(config-if-Serial0)# dialer map ip 131.108.2.5 name ZZZ 14155553434

Related Command

dialer in-band, dialer-group, dialer string dialer autodial-interval

no dialer pool

Syntax Description

numberDialer pool sequence number, ranging 1 to 255.

Default

no dialer pool.


11/29




1-10

Command Mode

Dialer interface configuration mode

Usage Guideline

This command can be used at the Dialer interface only, and one Dialer interface can

only correspond to one dialer pool.

Example

! Set the interface Dialer 1 as using dialer pool 3

Quidway(config-if-Dialer1)# ip address 1.1.1.1 255.255.255.0

Quidway(config-if-Dialer1)# encapsulation ppp

& Note:

If the dialer-group command is not configured, then DDR will not dial.

This command is valid only when one of the following conditions is met:

l No dialer map is configured at the interface.

l The corresponding command in the dialer map can not be identified for the next-hop address to which the packet is sent.

Example

! Set the dial string of dialer 1 to the destination as 11111

Quidway(config)# interface dialer 1

Quidway(config-if-Dialer1)# dialer map ip 131.108.2.5 name YYY 14155553434

Quidway(config-if-Dialer1)# dialer string 11111

Related Command

1.20 dialer-list

To control the condition for a DDR call, use the dialer-list command is used. To return

to the default, use the no form of this command.

dialer-list dialer-groupprotocolprotocol-name { permit | deny }

dialer-list dialer-grouplistaccess-list-number

no dialer-listdialer-group

Syntax Description

dialer-group Sequence number of the dialer access group, corresponding to the

dialer-groupgroup-numberin the DDR interface configuration.

deny Packets of a corresponding protocol denied.

access-list-number Access list number corresponding to the dialer access group.

Default

no dialer-list.

Command Mode

Global configuration mode

Usage Guideline

To set packet transmission control corresponding to a dialer access group, use he

dialer-group command to make an interface belong to a dialer access group so as tocomplete packet transmission control at a DDR interface.

If a dialer-group fails to identify a corresponding dialer-list, DDR will treat the packet as

an uninteresting one.

Example

! Set dialer access list

Quidway(config-if-Serial1)# dialer-group 1

Quidway(config)# access-list 101 deny igrp 0.0.0.0 255.255.255.255 255.255.255.255

0.0.0.0

18/29




1-17

1.21 interface dialer

To create a dialer rotary group in a standard DDR configuration or to define a dialer

interface in a flexible DDR configuration, use the interface dialercommand. To returnto the default, use the no form of this command.

interface dialernumber

no interface dialernumber

Syntax Description

number Interface sequence number, ranging 1 to 255.

Default

no interface dialer.

Command Mode


Usage Guideline

Dialer rotary groups allow a dialer interface configuration to be used in a group ofphysical interfaces, which can be used to call different destinations.

Dialer rotary groups are very effective when it is necessary to call multiple destination

addresses at the same time. All the commands are configured at the dialer interface,and each physical interface only needs to execute the dialer rotary-group command.

The physical interfaces in a Dialer rotary group do not have their own networkaddresses; instead, they use the addresses in the dialer interface.

Example

! Define dialer1 as a dialer interface

Quidway(config)# interface dialer 1

Related Command

dialer map, dialer rotary-group, dialer string, dialer remote-name

1.22 show dialer

To show the DDR interface information, use the show dialercommand.

show dialer[ interface interface-type interface-number]

Syntax Description

interface-type Interface type.

interface-number Interface sequence number.

Chapter 2 Modem Configuration Commands

Modem configuration commands include:

l chat-script

l modeml script startupl script activation

l script connectionl script dialerl script init-string

l script resetl script startupl start-chat

l show scriptl show script-event

2.1 chat-script

To define the Modem script in global mode, use the chat-script command. To return tothe default, use the no form of this command.

chat-scriptscript-name expect-send

no chat-scriptscript-name

Syntax Description

script-name Name of the script.

expect-sendContent of the script.

Default

no chat-script.

Command Mode


Usage Guideline

The Quidway series of routers provides the Modem script, which is mainly used for:

l Flexibly controlling Modems of different models. For example, differentinitialization strings are used to ensure interoperability and good coordinationbetween routers of different suppliers and models.

l For carrying out remote interactive logging and switching to different states via theinteractive negotiation between scripts. When async serial interfaces of bothrouters set up a connection via the Modem, for example, the protocol

encapsulated on this physical link and the working parameters of the protocol canbe determined via mutual negotiation.

Normal Modem script formats are shown as follows:


21/29




2-2

send-string1receive-string1send-string2receive-string2......

In the above formats:

l send-stringsends character string

l receive-stringreceives character stringl send-string and receive-stringnormally appear in pair, and script sending should

begin with character string, such as send-string1 receive-string1 ...... , whichrepresents the following process: send-string1 is sent to the Modem, expecting toreceive receive-string1. If the received string successfully matches receive-string1,

then continues executing the following script, otherwise stops executing the script.l If the last string is a sending string, this indicates that after this string is sent, the

execution of the script can be terminated, and it is no longer necessary to wait for

the receiving string.l If it is unnecessary to send a string at the beginning of a script, and you can

directly wait for the receiving string, then you can set the first send string as ,

whose meaning will be expounded later.l The sending string ends with \c, and an Enter sign is added to its end automatically

when it is sent.l The receiving string is matched via the location-independent matching method,

that is, the matching is considered successful as long as the received contentscontain the string expected to be received.

l As for receiving string matching, there can be multiple strings expected to bereceived, which are interconnected with -; as long as one of them matches, thematching is considered successful.

l The default wait-for-string timeout is 5 seconds. TIMEOUT seconds can beinserted at any point in the script to adjust the timeout value of the string, andremains valid until the next setting of TIMEOUT in the same script. Its meaning is

shown in the following table.

Table DC-2-1 List of script key words

Key word Description

ABORT receive-string ABORT is followed by a receive string, which is used to match the string from theModem or the remote DTE. The full matching method is used, that is, a script can

contain multiple ABORT settings, each of which is valid during the whole period ofscript execution.

TIMEOUT seconds TIMEOUT is followed by a number. It is used to set the timeout for the receive string. Ifno expected string is received within this time, then the execution of this script fails.This timeout value is valid after it is set until the next TIMEOUT setting.

l All the strings and keywords in the script are case sensitive.l The strings and key words are separated with a space. If a string contains a space,

this space should be contained in " ". If there is nothing between the quotation

marks (that is, ""), then this string may have two meanings:a) if "" is located at the beginning of the script, then this indicates that no string needs tobe forwarded, and you can just directly wait for the string;

b) if it is located in any place, then the content of this string is considered as "".

l ABORT receive-string can be inserted into the script to change the executionprocess of the script, indicating that if the received string fully matches receive-string, then the execution of this script is terminated. ABORT receive-strings can

appear for many times, and they will work interactively. As long as one of themmatches, the execution of the script will stop. No matter where ABORT receive-string appears, it functions during the whole process of script execution.

l An escape character can be inserted into the script so as to achieve better controlover the script and increase the flexibility of the script. In addition, all escapecharacters are also string separators. For detail, please refer to the following table.

2.3 modem-autoanswer

To set the external Modem at the async interface to autoanswer, use the modem-

autoanswercommand. To set the non-auto answer mode at the async interface, usethe no modem-autoanswercommand.

modem-autoanswer

nomodem-autoanswer

Default

no modem-autoanswer.

Command Mode


Usage Guideline

This command is executed according to the answer status of the external Modem of the

router. When the status of the Modem is set to autoanswer (the AA light of the Modemis on), modem-autoanswer must be executed in the corresponding interfaceconfiguration mode. If it is in the non-auto answer mode, then no modem-autoanswercan be executed.

Executing this command will not change the status of the Modem, but will reflect its

status. You should decide whether to execute the modem-autoansweraccording tothe answer status (AA light) of the current external Modem.

Example

! Set the external Modem at Serial0 to autoanswer

Quidway(config-if-Serial0)# modem-autoanswer

Related Command
