Description
Use the dialer bundle command to
configure a dialer bundle used by a dialer interface.
Use the undo dialer bundle command
to disassociate the dialer bundle from the dialer interface.
By default, the Resource-Shared DCC is not
enabled, neither is dialer bundle specified.
This command can be applied only on a
dialer interface for configuring the dialer bundle that the interface will use.
Furthermore, a dialer interface can only use a dialer bundle. This command can
be used to specify a dialer bundle used by a dialer interface, no matter what
link-protocol, PPP or Frame Relay, runs on the interface.
Related command: dialer bundle-member.

priority:
Priority of the physical interface in the dialer bundle, ranges from 1 to
255. The physical interface with higher priority will be used first. This is an
optional parameter. By default, priority is 1.
max-num: The
maximum number of channels that can be used.
min-num: The
minimum number of channels that can be used.
Description
Use the dialer bundle-member command
to configure a physical interface included in a dialer bundle in the Resource-Shared
DCC application.
Use the undo dialer bundle-member
command to remove the physical interface from the dialer bundle.
By default, the physical interface is not
assigned to any dialer bundle.
This command can only be applied to a
physical interface, which can be assigned to multiple dialer bundles.
To enable the B channel of ISDN interface (BRI or PRI) to configure its
link layer protocol dynamically in terms of the Dialer interface it belongs to,
link layer protocol that the interface uses should be specified as PPP.
Related command: dialer bundle.

Parameter
user: Calls
back according to the parameter user hostname configured in the dialer
route command.
dial-number:
Calls back according to the parameter telephone-number configured in the
local-user callback-number command.
Description
Use the dialer callback-center
command to enable the callback server function.
Use the undo dialer callback-center
command to disable the callback server function of a router.
By default, PPP callback server is not
configured.
This command must be configured at the
server end when PPP is used to implement callback.
The parameter user indicates that
DCC will call back according to the parameter configured in the dialer route
command. The parameter dial-number indicates that DCC will call back the
remote end according to the callback-number configured in the local-user
command.
When both user and dial-number
are applied concurrently, the router will first attempt to place a return call according
to the first parameter. If the callback attempt fails, it will try the second
parameter for callback.

Parameter
remote-number: Used for matching the remote incoming call number. The
character “*” represents any character.
callback:
When calling back the server end, the incoming number will match with the dialer
call-in command containing this keyword and originate a callback.
Description
Use the dialer call-in command to
enable ISDN callback according to ISDN caller ID.
Use the undo dialer call-in command
to cancel the configuration.
By default, ISDN callback according to ISDN
caller ID is not configured.
This command must be configured at the
server end when ISDN caller ID is applied for callback. In Resource-Shared DCC,
because both PPP and frame relay protocols can be encapsulated on dialer
interfaces, ISDN interface can encapsulate link layer protocol dynamically
according to corresponding dialer interface.
The caller first searches corresponding dialer
interface by matching the caller number with the dialer number command.
The dialer call-in command is used to preprocess the ISDN call-in
number, determining whether the user with this number can be permitted to
access. If the PBX switch does not provide the caller number, refuse the call
directly.
Related command: dialer callback-center.

Parameter
dial-number: Dial number for calling a remote end.
Description
Use the dialer number command to
configure a dial number for placing a call to a single remote end.
Use the undo dialer number command
to cancel the configured dial number.
By default, no dial number is set for
calling the remote end.
This command is used when the dialer
interface of Circular DCC serves as caller end and the dialer originates calls
to only one destination address or the default address. This command is only
valid after at least one of the following requirements is satisfied:
l
The dialer route command is not
configured on the interface.
l
The next hop address that sends packets cannot
be found in the corresponding dialer route command.
When dialer interfaces of Resource-Shared
DCC run link protocol of PPP, the remote user names, which are obtained via PPP
authentication and configured with dialer user respectively, will decide
which dialer interface will receive the incoming call. In this case, dialer
user must be configured, and dialer number can be configured
optionally.
When dialer interfaces run link protocol of
Frame Relay, the calling numbers, which are received from the incoming call and
configured with dialer number respectively, will decide which dialer
interface will receive the incoming call. In this case, dialer number
must be configured, and dialer user can be configured optionally.
l
If dialer-group command is not
configured, DCC will not dial even if dialer number command is
configured.
l
When using Resource-Shared DCC, the same dialer number
can be configured on different dialer interfaces at the calling side; but it is
not the case at the called side; otherwise, the call will fail. When using
Circular DCC, the same dialer number can be configured on different dialer
interfaces at the calling side, and it is the same to the called side.

specified for authentication implemented when receiving calls. Hostname
is a string of 1 to 80 characters.
broadcast:
An optional parameter indicating that the broadcast packets can be
transmitted on this link.
dial-number:
Dial number of the remote end.
autodial:
If this parameter is defined in a dialer route, the router will
automatically attempt to dial according to the dialer route at a certain
interval. The interval is set in the dialer autodial-interval command,
which is 300 seconds by default.
logical-channel logic-channel-number: Number of the
specified logic channel of the standby center.
interface interface-type interface-number:
Specifies to dial from the specified physical interface. When multiple physical
interfaces are assigned to a dialer interface and their dial-up links are
connected to different ISDN switches, you need to associate dial-up numbers
with physical interfaces. This configuration is intended for dialer interfaces
only and is not available with RS-DCC.
Description
Use the dialer route command to
allow a DCC interface to call the specified destination address (host or
network address) or to receive calls from multiple remote ends.
Use the undo dialer route command to
remove a dialer route.
By default, no dialer route is defined.
To originate a call, the parameter dial-number
must be configured. If the user keyword is used, PPP authentication
must be configured.
The user can configure multiple dialer
routes for a dial port or a destination address.
If the dialer-group
command is not configured, DCC will not dial.

Parameter
traffic-percentage: Percentage of the actual traffic on the link over the
bandwidth, ranges from 0 to 99.
in: Only
the inbound traffic is calculated.
in-out: Calculates
the larger one of the inbound traffic and the outbound traffic in the actual
traffic calculation.
out: Only
the outbound traffic is calculated.
Description
Use the dialer threshold command to
configure the traffic threshold of a link on the DCC interface so that another
link can be enabled to call the same destination address when the ratio of
traffic on all connected links on the DCC interface to the available bandwidth
exceeds the preset percentage.
Use the undo dialer threshold
command to restore the default value.
By default, MP flow control is not enabled.
If the ratio of the traffic on a link of a
DCC interface to the bandwidth exceeds the defined threshold, the second link
is brought up to form an MP bundle with the first one. When the ratio of
traffic on the two links to the bandwidth exceeds the specified threshold, the
third link is brought up, so on and so forth.
On the contrary, when the ratio of the
traffic on N (N is an integer greater than or equal to 2) links to the
bandwidth of N-1 links is less than the specified threshold, a link is dropped.
When only one link is left in the MP bundle, whether and when to disconnect it
depends on the timer configured using the dialer timer idle command. So
far, this command is not available with physical interfaces. It is only
applicable to dialer interfaces and must be used together with the ppp mp command.
With traffic-percentage set to 0,
the router does not look at the ratio of traffic to bandwidth when making calls
to bring up links. Rather, all the available links come up automatically. As
for links that already exist, they are not torn down because of timeout. Simply
put, the dialer threshold 0 command voids the dialer timer idle
command.

Description
Use the dialer timer autodial
command to configure the automatic dialing interval of DCC.
Use the undo dialer timer autodial
command to resume the default interval.
This command should be used together with
the auto-dial keyword in the dialer route command. DCC will
automatically attempt to dial at intervals of seconds until the
connection is established. The automatic dialing function is independent of the
trigger with data packets and the established connection will not be
automatically cut for timeout. That is, the configuration of the dialer
timer idle command does not affect it.

Description
Use the dialer timer compete command
to configure an idle interval for an interface after call contention occurs on
the interface.
Use the undo dialer timer compete
command to restore the default interval.
Contention occurs if no free channel is
available when DCC tries to originate a call. Normally, after a link is set up,
timer idle timing will take effect. However, if a call to a different
destination address is to be originated on this interface under the contention
circumstances, DCC replaces the timer idle timing with the timer
compete timing.

Description
Use the dialer timer idle command to
configure the interval that a link is allowed to be idle (in other words, the
interval when there is no packets which comply with the “permit”
statements transmitted) after a call has been set up on the interface.
Use the undo dialer timer idle
command to restore the default duration.
After a link is set up, the timer idle timer
will take effect. If no interesting packets are transmitted on the link within
the specified time, DCC will automatically disconnect the link. If timer
idle is set to 0, the link will never be disconnected, regardless of whether
there are no packets, which comply with the “permit” statements, to
be transmitted over the link or not.

By default, no conditions of packet-triggering
DCC calls are set for dial interfaces.
This command is used to set the DCC call
packet-triggering control to which an access control group corresponds. And a dial
interface can be placed in an access control group through the dialer-group
command. Thereby, the DCC call’s packet-triggering on the DCC interface
can be controlled.
If an access control group cannot
find the corresponding dialer-rule, DCC will regard the packets as packets
which do not comply with the “permit” conditions in ACL rule and
just drop them. No DCC call will be originated.

1.1.26 interface dialer
Syntax
interface dialer number
undo interface dialer number
View
System view
Parameter
number: Interface
number; its value range varies with router model.
Description
Use the interface dialer command to
create a dialer circular group for the Circular DCC, or configure a dialer
interface for the Resource-Shared DCC.
Use the undo interface dialer
command to cancel the existing setting.
By default, no dialer interface is defined.
In Resource-Shared DCC, any dialer
interface can use the services provided by multiple physical interfaces, and
individual physical interfaces can provide services for multiple dialer
interfaces at the same time. Therefore, authentication must be configured on
these physical interfaces, so as to use the user name of a dial-in party to
locate the corresponding dialer interface for the call. In this mode, physical
interfaces and dialer interfaces are dynamically bound. Furthermore, a dialer
interface can only call a destination address, which will be specified in the dialer
number command.
The physical interfaces in Circular DCC and
Resource-Shared DCC do not use individual network addresses. Instead, they use
the addresses of the corresponding dialer interfaces.
Example
# Define a dialer interface dialer 1.
[H3C] interface dialer 1
Syntax
flow-interval
seconds
undo
flow-interval
View
System view
Parameter
seconds: Traffic
statistic interval. It is in the range 1 to 1500 seconds and defaults to 300 seconds.
Description
Use the flow-interval command to
configure traffic statistic interval.
Use the undo flow-interval command
to restore the default traffic statistic interval. This command takes effect
only on DCC packet-triggered dial-up.
The command specifies intervals at which
the system provides statistics about traffic on the links in an MP bundle. It
is applied to the situation where whether links are brought up depends on
traffic size. Changing the interval setting can affect the interface traffic
statistic interval that you can see when executing the display interfaces
command.
Related command: dialer threshold, display
interface.
Example
# Set the traffic statistic interval to 10 seconds.
[H3C] flow-interval 10
Syntax
ppp callback
{ client | server [ force ] }
undo ppp callback { client | server [ force ] }
View
Physical or dialer interface view
Parameter
client: As
the client end, sends callback requests.
server: As
the server end, accepts callback requests.
force:
Forces the client to negotiate callback; otherwise the client call will be
refused.
Description
Use the ppp callback command to
enable an interface to send or accept PPP callback requests.
Use the undo ppp callback command to
disable the interface to send or accept PPP callback requests.
By default, sending or receiving callback
request is disabled.
The callback function can be used to save
the communication cost for the calling party in the case that the calling party
pays the charge for calls.
Related command: ppp callback ntstring.
Example
# Enable accepting callback request on
Serial0/0/0 interface.
[H3C-Serial0/0/0] ppp callback server
Syntax
ppp callback ntstring dial-number
undo ppp callback ntstring
View
Physical or dialer interface view
Parameter
dial-number:
Dial number for a Windows NT server to call back the router.
Description
Use the ppp callback ntstring
command to configure the dial number required for a Windows NT server to call
back the router.
Use the undo ppp callback ntstring
command to cancel the configured callback dial number.
By default, no callback dial number is set
for the Windows NT server.
When a router functions as the callback
server to call a Windows NT server, this command should be configured if the
server needs the router to send the callback number.
Related command: ppp callback.
Example
# Set the
dial number for a Windows NT server to call back the router to
“2489”.
[H3C-Dialer1]
ppp callback NTString 2489
