Parameters

chap: Configures the access device to use the Challenge Handshake Authentication Protocol (CHAP) to communicate with the RADIUS server.

pap: Configures the access device to use the Password Authentication Protocol (PAP) to communicate with the RADIUS server.

Usage guidelines

The device can use either of the following methods to perform MAC authentication with an authentication server:

· PAP—Transports usernames and passwords in plain text. The authentication method applies to scenarios that do not require high security.

· CHAP—Transports usernames in plain text and passwords in encrypted form over the network. CHAP is more secure than PAP.

Examples

# Configure the device to use CHAP for MAC authentication.

<Sysname> system-view

[Sysname] mac-authentication authentication-method chap

mac-authentication domain

Use mac-authentication domain to specify a global or port-specific authentication domain.

Use undo mac-authentication domain to restore the default.

Syntax

mac-authentication domain domain-name

Parameters

domain-name: Specifies the name of an ISP domain, a case-insensitive string of 1 to 255 characters.

Usage guidelines

The global authentication domain applies to all MAC authentication-enabled ports. An authentication domain specified in Layer 2 Ethernet interface view applies only to the port. You can specify different authentication domains on different ports.

A port chooses an authentication domain for MAC authentication users in the following order:

1. Authentication domain specified on the port.

2. Global authentication domain specified in system view.

3. Default authentication domain.

Examples

# Specify ISP domain domain1 as the global MAC authentication domain.

<Sysname> system-view

[Sysname] mac-authentication domain domain1

# Specify ISP domain aabbcc as the MAC authentication domain on GigabitEthernet 1/0/1.

[Sysname] interface gigabitethernet 1/0/1

Syntax

mac-authentication timer { offline-detect offline-detect-value | quiet quiet-value | server-timeout server-timeout-value }

undo mac-authentication timer { offline-detect | quiet | server-timeout }

Default

· The offline detect timer is 300 seconds.

· The quiet timer is 60 seconds.

· The server timeout timer is 100 seconds.

Parameters

offline-detect offline-detect-value: Sets the offline detect timer in seconds, in the range of 60 to 2147483647.

quiet quiet-value: Sets the quiet timer in seconds, in the range of 1 to 3600.

server-timeout server-timeout-value: Sets the server timeout timer in seconds, in the range of 100 to 300.

Usage guidelines

MAC authentication uses the following timers:

· Offline detect timer—Sets the interval that the device waits for traffic from a user before the device determines that the user is idle. If the device has not received traffic from a user before the timer expires, the device logs off that user and requests the accounting server to stop accounting for the user.

· Quiet timer—Sets the interval that the device must wait before the device can perform MAC authentication for a user that has failed MAC authentication. All packets from the MAC address are dropped during the quiet time. This quiet mechanism prevents repeated authentication from affecting system performance.

· Server timeout timer—Sets the interval that the device waits for a response from a RADIUS server before the device determines that the RADIUS server is unavailable. If the timer expires during MAC authentication, the user cannot access the network.

Examples

# Set the server timeout timer to 150 seconds.

<Sysname> system-view

[Sysname] mac-authentication timer server-timeout 150

mac-authentication user-name-format

Use mac-authentication user-name-format to configure the type of user accounts for MAC authentication users.

Use undo mac-authentication user-name-format to restore the default.

Syntax

undo mac-authentication user-name-format

Default

Each user's MAC address is used as the username and password for MAC authentication. The MAC addresses are in hexadecimal notation without hyphens, and letters are in lower case.

Views

System view

Predefined user roles

network-admin

context-admin

Parameters

fixed: Uses a shared account for all MAC authentication users.

account name: Specifies the username for the shared account. The name is a case-sensitive string of 1 to 55 characters, excluding the at sign (@). If you do not specify a username, the default name mac applies.

password: Specifies the password for the shared user account. If you do not specify a password, the shared user account does not have a password.

cipher: Specifies a password in encrypted form.

simple: Specifies a password in plaintext form. For security purposes, the password specified in plaintext form will be stored in encrypted form.

string: Specifies the password. Its plaintext form is a case-sensitive string of 1 to 63 characters. Its encrypted form is a case-sensitive string of 1 to 117 characters.

mac-address: Uses MAC-based user accounts for MAC authentication users. You can also specify the format of username and password by using the following keywords:

· with-hyphen: Includes hyphens in the MAC address.

¡ six-section: Hyphenates the MAC address into six groups of two hexadecimal digits, for example, xx-xx-xx-xx-xx-xx or XX-XX-XX-XX-XX-XX.

¡ three-section: Hyphenates the MAC address into three groups of four hexadecimal digits, for example, xxxx-xxxx-xxxx or XXXX-XXXX-XXXX.

If you do not specify the six-section or three-section keyword, the MAC address is in six-section format.

· without-hyphen: Excludes hyphens from the MAC address, for example, xxxxxxxxxxxx or XXXXXXXXXXXX.

· lowercase: Specifies letters in lower case.

· uppercase: Specifies letters in upper case.

Usage guidelines

If you specify the MAC-based user account, the device uses the MAC address of a user as the username and password for MAC authentication of the user. This user account type ensures high authentication security. However, you must create on the authentication server a user account for each user, using the MAC address of the user as both the username and password.

If you specify a shared user account, the device uses the specified username and password for MAC authentication of all users. Because all MAC authentication users use a single account for authentication, you only need to create one account on the authentication server. This user account type is suitable for trusted networks.

Examples

# Configure a shared account for MAC authentication users, and set the username to abc and password to plaintext string of xyz.

<Sysname> system-view

[Sysname] mac-authentication user-name-format fixed account abc password simple xyz

# Use MAC-based user accounts for MAC authentication users. The MAC addresses must be in hexadecimal notation without hyphens, and letters are in upper case.

<Sysname> system-view

Parameters

interface interface-type interface-number: Specifies a port by its type and number.

mac mac-address: Specifies a MAC authentication user by its MAC address. The mac-address argument is in the format of H-H-H.

username username: Specifies a MAC authentication user by its name. The username argument is a case-sensitive string of 1 to 253 characters.

vlan vlan-id: Specifies a VLAN by its VLAN ID. The value range for the vlan-id argument is 1 to 4094.

vsi vsi-name: Specifies a VSI by its name. The vsi-name argument is a case-sensitive string of 1 to 31 characters.

Usage guidelines

Use this command to log off the specified MAC authentication users and clear information about these users from the device. These users must perform MAC authentication to come online again.

With a VSI specified, this command logs off a MAC authentication user if that user has passed authentication and its authorization VSI is the specified VSI.

With a VLAN specified, this command logs off the following MAC authentication users:

· Users that have passed MAC authentication and have been assigned the specified VLAN as their authorization VLAN by the server.

· Users that stay in the specified VLAN after they have passed MAC authentication, because they have not been assigned an authorization VLAN yet.

· Users that are performing MAC authentication in the specified VLAN.

To identify the VLAN in which a user is staying, use the display mac-address command.

If you do not specify any parameters, the reset mac-authentication access-user command logs off all MAC authentication users on the device.

Examples

# Log off all MAC authentication users on GigabitEthernet 1/0/1.

<Sysname> reset mac-authentication access-user interface gigabitethernet 1/0/1
