PPPoE client commands
dialer diagnose
Use dialer diagnose to configure DDR to operate in diagnostic mode.
Use undo dialer diagnose to restore the default.
Syntax
dialer diagnose [interval interval ]
undo dialer diagnose
Default
DDR operates in non-diagnostic mode.
Views
Dialer interface view
Predefined user roles
network-admin
Parameters
seconds: Specifies the diagnostic interval in the range of 5 to 65535 seconds. The default is 120
seconds.
Usage guidelines
This command takes effect only when a dialer interface is used with PPPoE client application.
In diagnostic mode, the device dials a PPPoE connection immediately after the device configurations are
complete, automatically terminates the connection and starts the auto-dial timer after a configurable
diagnostic interval, and redials a connection when the auto-dial timer expires. By establishing and
terminating PPPoE sessions periodically, you can monitor the operating status of the PPPoE link.
In diagnostic mode, the link idle-timeout timer is ignored.
Examples
# Configure interface Dialer 1 to operate in diagnostic mode, with a diagnostic interval of 300 seconds.
<Sysname> system-view
[Sysname] interface dialer 1
[Sysname-Dialer1] dialer diagnose interval 300

Parameters
dial-bundle-number number: Specifies the dialer bundle number corresponding to a PPPoE session. A
dialer bundle number uniquely identifies a PPPoE session. It can also be used as a PPPoE session ID. The
value range for the number argument is 0 to 1023.
no-hostuniq: Configures the client not to carry the Host-Uniq field in discovery packets. Without this
keyword, the client carries the Host-Unique field. The Host-Unique field uniquely identifies a PPPoE client
when an interface is configured with multiple PPPoE sessions. When the PPPoE server receives a packet
with this field, it must include this field unmodified in the response packet. The device identifies the PPPoE
client where the response packet belongs based on the Host-Unique field in the response packet.
Examples
# Establish a PPPoE session on Layer 3 Ethernet interface Ethernet 1/1.
<Sysname> system-view
[Sysname] interface ethernet 1/0
[Sysname-Ethernet1/1] pppoe-client dial-bundle-number 1

L2TP commands
allow l2tp
Use allow l2tp to configure an LNS to accept L2TP tunneling requests from a specified LAC, and to
specify a VT interface for tunnel setup.
Use undo allow to restore the default.
Syntax
•For L2TP group 1:
allow l2tp virtual-template virtual-template-number [ remote remote-name ]
undo allow
•For L2TP groups other than L2TP group 1:
allow l2tp virtual-template virtual-template-number remote remote-name
undo allow
Default
An LNS denies L2TP tunneling requests from any LACs.
Views
L2TP group view
Predefined user roles
network-admin
Parameters
virtual-template virtual-template-number: Specifies a VT interface by its number in the range of 0 to 1023.
An LNS dynamically creates virtual access (VA) interfaces based on the configuration of a VT interface.
Each VA interface is used to carry data for a different L2TP session.
remote remote-name: Specifies the name of the tunnel peer (LAC) initiating tunneling requests, a
case-sensitive string of 1 to 31 characters.
Usage guidelines
The allow l2tp command is available only to L2TP groups in LNS mode.
Make sure the specified name of the tunnel peer is consistent with the local name configured on the LAC.
If you execute this command multiple times for an L2TP group, the most recent configuration takes effect.
For L2TP group 1, if you do not specify the remote remote-name option, an LNS accepts tunneling
requests from any LACs. In this case, L2TP group 1 serves as the default L2TP group.
The allow l2tp command is available only to LNSs. When an LAC that initiates a tunneling request
matches the tunnel peer name configured in an L2TP group, the LNS uses the tunnel parameters (for
example, tunnel authentication and flow control) configured in this L2TP group for tunnel setup. When the
LAC does not match the tunnel peer name configured in any L2TP group, the LNS uses the tunnel
parameters for the default L2TP group (if it exists), or it cannot set up a tunnel with the LAC (if the default
L2TP group does not exist).

7
HP recommends that you configure a default L2TP group on the LNS in the following cases:
•There are LACs (such as hosts with Windows 2000 Beta 2 installed) that include blank local names
in their tunneling requests.
•The LNS sets up tunnels with multiple LACs by using the same tunnel parameters.
Examples
# Specify L2TP group 1 as the default L2TP group, and specify Virtual-Template 1 for tunnel setup. For
L2TP group 2, configure the LNS to accept the L2TP tunneling request initiated by the peer (LAC) named
aaa ,and specify Virtual-Template 2 for tunnel setup.

Cause
Causes for the physical state of the interface to be Down:
•Not connected—No physical connection exists (possibly because the
L2TP negotiation fails or insufficient configuration exists to trigger L2TP
negotiation).
•Administratively—The interface was shut down by using the shutdown
command. To restore the physical state of the interface, use the undo
shutdown command.

interface virtual-ppp
Use interface virtual-ppp to create a virtual PPP interface and enter its view. If the interface has been
created, you directly enter its view.
Use undo interface virtual-ppp to remove a virtual PPP interface.
Syntax
interface virtual-ppp interface-number
undo interface virtual-ppp interface-number
Default
No virtual PPP interface exists.
Views

Parameters
interface-number: Specifies a virtual PPP interface by its number in the range of 0 to 255.
Usage guidelines
A virtual PPP interface is required on the LAC for establishing an LAC-auto-initiated L2TP tunnel.
Examples
# Create virtual PPP interface Virtual-PPP 10 and enter its view.
<Sysname> system-view
[Sysname] interface virtual-ppp 10
[Sysname-Virtual-PPP10]
l2tp enable
Use l2tp enable to enable the L2TP function.
Use undo l2tp enable to disable the L2TP function.
Syntax

Usage guidelines
L2TP must be enabled for relevant L2TP configurations to take effect.
Examples
# Enable the L2TP function.
<Sysname> system-view
[Sysname] l2tp enable
l2tp-auto-client
Use l2tp-auto-client to trigger an LAC to automatically establish an L2TP tunnel.
Use undo l2tp-auto-client to remove the automatically established L2TP tunnel.
Syntax
l2tp-auto-client l2tp-group group-number
undo l2tp-auto-client
Default
An LAC does not automatically establish an L2TP tunnel.
Views
Virtual PPP interface view
Predefined user roles
network-admin
Parameters
l2tp-group group-number: Specifies an L2TP group whose tunnel parameters are used by the LAC to
establish the tunnel. The value range for the group-number argument is 1 to 65535.
Usage guidelines
The L2TP group specified must be an existing one in LAC mode.
An L2TP tunnel automatically established in LAC-auto-initiated mode exists until you remove the tunnel by
using the undo l2tp-auto-client or undo l2tp-group group-number command.
Examples
# Trigger the LAC to automatically establish an L2TP tunnel by using the tunnel parameters of L2TP group
10.
<Sysname> system-view
[Sysname] interface virtual-ppp 1

Parameters
group-number: Specifies an L2TP group by its number in the range of 1 to 65535.
mode: Specifies a mode for the L2TP group.
lac: Specifies the LAC mode.
lns: Specifies the LNS mode.
Usage guidelines
To create a new L2TP group, you must specify the mode keyword. To enter the view of an existing L2TP
group, you do not need to specify this keyword.
In L2TP group view, you can configure L2TP tunnel parameters, such as tunnel authentication and flow
control.
A device can have L2TP groups in both LAC and LNS modes at the same time, and can have a maximum
number of 1000 L2TP groups.
Examples
# Create L2TP group 2 in LAC mode, and enter its view.
<Sysname> system-view
[Sysname] l2tp-group 2 mode lac
[Sysname-l2tp2]
