link-protocol slip
Use link-protocol slip to enable SLIP encapsulation on an interface.
Syntax
link-protocol slip
Views
Interface view
Default command level
2: System level
Usage guidelines
Enable SLIP encapsulation only on asynchronous interfaces. For a synchronous/asynchronous interface,
switch it to the asynchronous mode, and then enable SLIP encapsulation on it.
Some asynchronous interfaces do not support the SLIP protocol, but you can still configure the
link-protocol slip command on it. When you do that, the system informs you that the operation of SLIP
encapsulation fails. By then, no encapsulation is enabled on the interface. You must use the link-protocol
ppp command to enable PPP encapsulation on the interface to make it available again.
Example
# Enable SLIP encapsulation on synchronous/asynchronous interface Serial 2/0.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] physical-mode async
[Sysname-Serial2/0] async mode protocol

PPP configuration commands
ip address ppp-negotiate
Use ip address ppp-negotiate to enable IP address negotiation on the local interface, so that the local
interface can accept the IP address allocated by the peer end.
Use undo ip address ppp-negotiate to disable IP address negotiation.
Syntax
ip address ppp-negotiate
undo ip address ppp-negotiate
Default
IP address negotiation is disabled.

ip pool
Use ip pool to configure an address pool for assigning IP addresses to PPP users.
Use undo ip pool to remove an address pool.
Syntax
ip pool pool-number low-ip-address [high-ip-address ]
undo ip pool pool-number
Default
No IP address pool is configured for PPP users.

Views
System view, ISP domain view
Default command level
2: System level
Parameters
pool-number: Number of the address pool, in the range of 0 to 99.
low-ip-address: Start address of the address pool.
high-ip-address: End IP address of the address pool. An address pool can contain up to 1024 IP
addresses. If the end IP address is not specified, the address pool has only one IP address, the start IP
address.
Usage guidelines
IP address pools configured in system view are for PPP users that do not need authentication. To configure
an IP address pool for the peer PPP users, use the remote address command in a specified interface view.
IP address pools configured in ISP domain view are for PPP users that need authentication in the specified
ISP domain. These IP address pools apply to the interfaces that connect to a larger number of PPP users
than those the interfaces can assign IP addresses for. For example, an Ethernet interface running PPPoE
can accommodate up to 4096 users, but you can configure only one address pool containing up to 1024
addresses on the virtual template of the Ethernet interface, which cannot meet the demand. However, IP
address pools configured in ISP domains can solve the problem.
Examples
# Configure IP address pool 0, with the IP addresses 129.102.0.1 through 129.102.0.10.
<Sysname> system-view
[Sysname] domain test
[Sysname-isp-test] ip pool 0 129.102.0.1 129.102.0.10

Parameters

<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] ppp accm 01010101
ppp account-statistics enable
Use ppp account-statistics enable to enable PPP traffic statistics collection.
Use undo ppp account-statistics enable to disable PPP traffic statistics collection.
Syntax

undo ppp account-statistics enable
Default
PPP traffic statistics collection is disabled.

Parameters
acl: Generates PPP accounting statistics for traffic that matches the configured ACL. If no ACL is
configured, the device generates PPP accounting statistics for all traffic.
acl-number: ACL number in the range of 2000 to 3999, where:
•2000 to 2999 are numbers for basic IPv4 ACLs.
•3000 to 3999 are numbers for advanced IPv4 ACLs.
name acl-name: Specifies an ACL by its name. The acl-name represents the name of an IPv4 ACL, a
case-sensitive string that starts with an English letter and contains 1 to 63 characters. To avoid confusion,
do not use the English word all as an IPv4 ACL name.

ppp acfc local
Use ppp acfc local to configure the local end to send ACFC requests, that is, configure the local end to
include the ACFC option in its outbound LCP negotiation requests.
Use undo ppp acfc local to restore the default.
Syntax
ppp acfc local request
undo ppp acfc local
Default
The local end does not include the ACFC option in its outbound LCP negotiation requests.

Parameters
request: Specifies that the local end include the ACFC option in its transmitted LCP negotiation requests.

ppp acfc remote
Use ppp acfc remote to configure how the local end handles the ACFC requests received from the remote
peer.

Use undo ppp acfc remote to restore the default.
Syntax
ppp acfc remote { apply | ignore | reject }
undo ppp acfc remote
Default
The device accepts ACFC requests received from a remote peer, but does not perform ACFC on frames
sent to the peer.

Parameters
apply: Configures the local end to accept ACFC requests received from the remote peer and to perform
ACFC on frames sent to the peer.
ignore: Configures the local end to accept ACFC requests received from the remote peer, but not to
perform ACFC on frames sent to the peer.
reject: Configures the local end to reject ACFC requests sent from the remote peer.

ppp authentication-mode
Use ppp authentication-mode to configure the PPP authentication mode.
Use undo ppp authentication-mode to disable PPP authentication.
Syntax
ppp authentication-mode { chap | ms-chap | ms-chap-v2 | pap } * [ [ call-in ] domain isp-name ]
undo ppp authentication-mode
Default
PPP authentication is disabled.
Views
Interface view
Default command level
2: System level
Parameters
chap: Uses CHAP authentication.

7
ms-chap: Uses MS-CHAP authentication.
ms-chap-v2: Uses MS-CHAP-V2 authentication.
pap: Uses PAP authentication.
call-in: Authenticates the call-in users only.
domain isp-name: Specifies the domain name for authentication, a case-insensitive string of 1 to 24
characters.
Usage guidelines
If you run the ppp authentication-mode command with the domain keyword specified, you must
configure an address pool in the corresponding domain. You can use the display domain command to
display the domain configuration.
If you configure the ppp authentication-mode command without specifying the domain name, the system
checks the username for domain information. If the username contains a domain name, the domain will
be used for authentication If the domain does not exist, the user's access request will be denied. If the
username does not contain a domain name, the default domain is used. You can use the domain default
command to configure the default domain. If no default domain is configured, the default domain system
is used by default.
PPP authentication includes the following categories:
•PAP—Two-way handshake authentication. The password used is in plain text.
•CHAP—Three-way handshake authentication. The password is in cipher text.
•MS-CHAP—Three-way handshake authentication. The password is in cipher text.
•MS-CHAP-V2—Three-way handshake authentication. The password is in cipher text.
You can configure several authentication modes simultaneously.
In any PPP authentication mode, AAA determines whether a user can pass the authentication through a
local authentication database or an AAA server. For more information about AAA, see Security
Configuration Guide.
For authentication on a dial-up interface, configure authentication on both the physical interface and the
dialer interface. When a physical interface receives a DCC call request, it first initiates PPP negotiation
and authenticates the dial-in user, and then passes the call to the upper layer protocol.

Default command level
2: System level
Parameters
cipher: Sets a ciphertext password.
simple: Sets a plaintext password.
password: Specifies the password string for CHAP authentication. This argument is case sensitive. If
simple is specified, it must be a string of 1 to 48 characters. If cipher is specified, it must be a ciphertext
string of 1 to 97 characters.
Usage guidelines
For security purposes, all passwords, including passwords configured in plain text, are saved in cipher
text to the configuration file.

ppp chap user
Use ppp chap user to set the username for CHAP authentication.
Use undo ppp chap user to cancel the configuration.
Syntax
