Usage guidelines

This command takes effect only on MAC authentication users who use static IP addresses. It prevents those users from modifying their IP addresses to access the network. Users who obtain IP addresses through DHCP are not affected.

Do not configure this command together with the mac-authentication guest-vlan command on a port. If both commands are configured, users in the MAC authentication guest VLAN cannot perform a new round of authentication.

Examples

# Include user IP addresses in MAC authentication requests on FortyGigE 1/1/1.

Predefined user roles

network-admin

Parameters

critical-vlan-id: Specifies a VLAN as the MAC authentication critical VLAN. The value range for the VLAN ID is 1 to 4094. Make sure the VLAN has been created and is not a super VLAN. For more information about super VLANs, see Layer 2—LAN Switching Configuration Guide.

Usage guidelines

The MAC authentication critical VLAN accommodates users who fail MAC authentication because all the servers in their ISP domains are unreachable. Users in this critical VLAN can access a limited set of network resources.

The critical VLAN feature takes effect when MAC authentication is performed only through RADIUS servers. If a MAC authentication user fails local authentication after RADIUS authentication, the user is not assigned to the critical VLAN.

Before you delete a VLAN that has been set as a MAC authentication critical VLAN, use the undo mac-authentication critical vlan command to remove the critical VLAN configuration.

Examples

# Configure VLAN 100 as the MAC authentication critical VLAN on FortyGigE 1/1/1.

<Sysname> system-view

[Sysname] interface fortygige 1/1/1

[Sysname-FortyGigE1/1/1] mac-authentication critical vlan 100

Parameters

domain-name: Specifies the name of an ISP domain, a case-insensitive string of 1 to 24 characters.

Usage guidelines

The global authentication domain applies to all MAC authentication-enabled ports. A port-specific authentication domain 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 domain domain1 as the global MAC authentication domain.

<Sysname> system-view

[Sysname] mac-authentication domain domain1

# Specify domain aabbcc as the MAC authentication domain on port FortyGigE 1/1/1.

Syntax

mac-authentication host-mode multi-vlan

Default

MAC authentication multi-VLAN mode is disabled on a port. When the port receives a packet sourced from an authenticated MAC address in a VLAN not matching the existing MAC-VLAN mapping, the device logs off and reauthenticates the user.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

Usage guidelines

The MAC authentication multi-VLAN mode prevents an authenticated online user from service interruption caused by VLAN changes on a port. When the port receives a packet sourced from the user in a VLAN not matching the existing MAC-VLAN mapping, the device neither logs off the user nor reauthenticates the user. The device creates a new MAC-VLAN mapping for the user, and traffic transmission is not interrupted. The original MAC-VLAN mapping for the user remains on the device until it dynamically ages out. H3C recommends that you configure this feature on hybrid or trunk ports.

This feature improves transmission of data that is vulnerable to delay and interference. It is typically applicable to IP phone users.

Examples

# Enable MAC authentication multi-VLAN mode on FortyGigE 1/1/1.

Predefined user roles

network-admin

Parameters

offline-detect offline-detect-value: Sets the offline detect timer in the range of 60 to 65535, in seconds.

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

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

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 regards the user idle. If a user connection has been idle within the interval, the device logs the user out and stops accounting for the user.

· Quiet timer—Sets the interval that the device must wait before the device can perform MAC authentication for a user who 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 regards the RADIUS server 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

mac-authentication timer auth-delay

Use mac-authentication timer auth-delay to enable MAC authentication delay and set the delay time.

Use undo mac-authentication timer auth-delay to restore the default.

Syntax

undo mac-authentication timer auth-delay

Default

MAC authentication delay is disabled.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

Parameters

time: Sets the delay time for MAC authentication in seconds. The value range is 1 to 180.

Usage guidelines

When both 802.1X authentication and MAC authentication are enabled on a port, you can delay MAC authentication so that 802.1X authentication is preferentially triggered. If no 802.1X authentication is triggered or if 802.1X authentication fails within the delay period, the port continues to process MAC authentication.

Do not set the port security mode to mac-else-userlogin-secure or mac-else-userlogin-secure-ext when you want to use MAC authentication delay. The delay does not take effect on a port in either of the two modes. For more information about port security modes, see "Port security commands."

Examples

# Enable MAC authentication delay on interface FortyGigE 1/1/1, and set the delay time to 10 seconds.

<Sysname> system-view

Default

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

Views

Predefined user roles

network-admin

Parameters

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

account name: Specifies the username for the shared account. The name takes 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:

cipher: Sets a ciphertext password.

simple: Sets a plaintext password.

password: Specifies the password. This argument is case sensitive.

· If the simple keyword is specified, the password must be a string of 1 to 117 characters.

· If the cipher keyword is specified, the password must be a ciphertext string of 1 to 88 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, for example xx-xx-xx-xx-xx-xx.

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

· lowercase: Enters letters in lower case.

· uppercase: Enters 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.

For security purposes, all passwords, including passwords configured in plain text, are saved in cipher text.

Examples

# Configure a shared account for MAC authentication users, set the username as abc and password as 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. Each MAC address must be in the hexadecimal notation with hyphens, and letters are in upper case.
