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.
Usage guidelines
The MAC authentication critical VLAN accommodates users that have failed MAC authentication because all the servers in their ISP domains are unreachable. Users in the critical VLAN can access network resources in the critical VLAN.
You cannot specify a VLAN as both a super VLAN and a MAC authentication critical VLAN on a port. For more information about super VLANs, see Layer 2—LAN Switching Configuration Guide.
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 GigabitEthernet 1/0/1.

Syntax
mac-authentication host-mode multi-vlan
undo mac-authentication host-mode
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. As a best practice, 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 GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] mac-authentication host-mode multi-vlan

Predefined user roles
network-admin
Parameters
max-number: Sets the maximum number of concurrent MAC authentication users on the port. The value range for this argument is 1 to 4294967295.
Usage guidelines
Set the maximum number of concurrent MAC authentication users on a port to prevent the system resources from being overused. When the maximum number is reached, the port denies subsequent MAC authentication users.
Examples
# Configure GigabitEthernet 1/0/1 to support a maximum of 32 concurrent MAC authentication users.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1

· The offline detect timer is 300 seconds.
· The quiet timer is 60 seconds.
· The server timeout timer is 100 seconds.
Views
System view
Predefined user roles
network-admin
Parameters
offline-detect offline-detect-value: Specifies the offline detect timer in the range of 60 to 65535, in seconds.
quiet quiet-value: Specifies the quiet timer in the range of 1 to 3600, in seconds.
server-timeout server-timeout-value: Specifies 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 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.

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
mac-authentication timer auth-delay time
undo mac-authentication timer auth-delay
Default
MAC authentication delay is disabled. MAC authentication starts immediately after it is triggered by a user packet.

Parameters
time: Specifies 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 GigabitEthernet 1/0/1 and set the delay time to 10 seconds.

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
mac-authentication user-name-format { fixed [ account name ] [ password { cipher | simple } string ] | mac-address [ { with-hyphen [ six-section | three-section ] | without-hyphen } [ lowercase | uppercase ] ] }
undo mac-authentication user-name-format
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.

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.
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.

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