Parameters

profile profile-name: Specifies a MAC authentication user recovery profile by its name, a case-insensitive string of 1 to 31 characters.

Usage guidelines

This feature enables the device to automatically obtain MAC authentication user information from a RESTful server and perform a reauthentication after the device or an interface module reboots or after an interface recovers from a failure.

This feature recovers the online state of MAC authenticated users quickly without waiting for packets from the MAC authentication users to trigger a reauthentication. It is helpful when the network has a large number of dumb terminals or the operation of dumb terminals is important for services.

To define the profile used for obtaining MAC authentication user information from a RESTful server, use the mac-authentication user-recovery-profile command.

For this feature to take effect after the device reboots, use the save command to save the configuration to the next-startup configuration file after you configure this feature. For more information about the save command, see configuration file management commands in Fundamentals Command Reference.

The automatic MAC authentication user recovery feature is mutually exclusive with the RADIUS accounting-on feature. Do not use the two features together. For more information about the RADIUS accounting-on feature, see AAA configuration in User Access and Authentication Configuration Guide.

network-admin

Parameters

exclude-ip: Specifies an ACL-based filter to identify source IP addresses that can or cannot trigger MAC authentication.

acl acl-number: Specifies a basic ACL. The value range for the acl-number argument is 2000 to 2999.

Usage guidelines

IMPORTANT:

This command can only operate in conjunction with an IMC server.

To avoid IP conflicts that result from changes to static IP addresses, use this command on a port that has MAC authentication users with static IP addresses.

This command adds user IP addresses to the MAC authentication requests sent to the authentication server. When MAC authentication is triggered for a user, the device checks the user's IP address for invalidity.

· If the IP address is valid, the device sends a MAC authentication request with the IP address included.

· If the IP address is not a valid host IP address or the triggering packet does not contain an IP address, the device does not initiate MAC authentication.

· If the packet is a DHCP packet with a source IP address of 0.0.0.0, the device sends a MAC authentication request without including the IP address. In this case, the IMC server does not examine the user IP address when it performs authentication.

Upon receipt of the authentication request that includes a user's IP address, the IMC server compares the user's IP and MAC addresses with its IP-MAC mappings.

· If an exact match is found or if no match is found, the user passes MAC authentication. In the latter case, the server creates an IP-MAC mapping for the user.

· If a mapping is found for the MAC address but the IP addresses do not match, the user fails the MAC authentication.

If the user host is configured with IPv6, the device might receive packets that contain an IPv6 link-local address, which starts with fe80. MAC authentication failure will occur if this address is used in MAC authentication. To avoid MAC authentication failure, configure a basic ACL to exclude the IPv6 IP addresses that start with fe80.

When you configure the ACL, follow these guidelines:

· Use permit rules to identify source IP addresses that are valid for MAC authentication. Use deny rules to identify source IP addresses that cannot trigger MAC authentication.

· In the rules, only the action keyword (permit or deny) and the source IP match criterion can take effect.

· As a best practice, configure a deny rule to exclude the IPv6 IP addresses that start with fe80 from triggering MAC authentication.

· If you configure permit rules, add a deny all rule at the bottom of the ACL.

Examples

# Include user IP addresses in MAC authentication requests on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] mac-authentication carry user-ip

Predefined user roles

network-admin

Parameters

critical-vlan-id: Specifies a VLAN as the critical VLAN for MAC authentication. The value range for the VLAN ID is 1 to 4094. Make sure the VLAN has been created.

Usage guidelines

The critical VLAN for MAC authentication 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.

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 critical VLAN for MAC authentication on GigabitEthernet 1/0/1.

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.

Parameters

guest-vlan-id: Specifies a VLAN as the guest VLAN for MAC authentication. The value range for the VLAN ID is 1 to 4094. Make sure the VLAN has been created.

Usage guidelines

The guest VLAN for MAC authentication accommodates users that have failed MAC authentication for any reason other than server unreachable. For example, the VLAN accommodates users with invalid passwords entered. You can deploy a limited set of network resources in the guest VLAN for MAC authentication. For example, a software server for downloading software and system patches.

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

Examples

# Configure VLAN 100 as the guest VLAN for MAC authentication on GigabitEthernet 1/0/1.

Predefined user roles

network-admin

Usage guidelines

The guest VLAN reauthentication feature of MAC authentication enables the device to reauthenticate users in the guest VLAN for MAC authentication on a port at reauthentication intervals.

Typically, you disable this feature to suppress excessive authentication failure log messages, which might occur when a network issue results in a large number of reauthentication failures.

If guest VLAN reauthentication is disabled on a port, the device does not reauthenticate users in the guest VLAN for MAC authentication on the port. The guest VLAN users will stay in the guest VLAN until they age out. To configure the aging timer, use the mac-authentication timer user-aging guest-vlan aging-time-value command.

Examples

# Enable the guest VLAN reauthentication feature of MAC authentication on GigabitEthernet 1/0/1.

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.

Parameters

mac-address mac-address: Specifies a MAC address in the format of H-H-H.

mask mask: Specifies a MAC address mask, in the format of H-H-H. Make sure the most significant bits of the MAC address mask in binary format are consecutive 1s.

mask mask-length: Specifies a MAC address mask length, in the range of 1 to 48.

account name: Specifies a username. The name is a case-sensitive string of 1 to 55 characters, and cannot include the at sign (@).

password: Specifies the user 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.

all: Specifies all MAC address ranges.

Usage guidelines

Use this command to configure user account settings for users in a MAC address range (for example, users with a specific OUI). For users in the specified range, this command has higher priority than the mac-authentication user-name-format command.

You can configure a maximum of 16 MAC address ranges. However, you must make sure the MAC address ranges do not overlap.

If you configure user account settings multiple times for the same MAC address range, the most recent configuration overwrites the previous configuration.

The mac-authentication mac-range-account command applies only to unicast MAC addresses.

· If you specify a MAC address range that contains only multicast MAC addresses, execution of this command will fail.

· If you specify a MAC address range that contains both unicast and multicast MAC addresses, the command takes effect only on unicast MAC addresses.

The all-zero MAC address is invalid for MAC authentication. Users with the all-zero MAC address cannot pass MAC authentication.

Examples

# Configure a user account for MAC addresses that start with aaaa. Set the MAC address mask to ffff-0000-0000, the username to user1, and the password to 1234 in plaintext form.

Usage guidelines

The MAC authentication offline detection feature monitors the online status of MAC authentication users. This feature uses an offline detect timer to set the interval that the device must wait 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.

To set the offline detect timer, use the mac-authentication timer command.

Examples

# Disable MAC authentication offline detection on GigabitEthernet 1/0/1.

Parameters

mac-address: Specifies a MAC address in the format of H-H-H, excluding multicast, all-zero, and all-F MAC addresses.

ignore: Skips offline detection for the specified user.

timer offline-detect-value: Specifies the offline detect timer for the specified user. The value range is 60 to 2147483647 seconds.

check-arp-or-nd-snooping: Uses the ARP snooping or ND snooping table in offline detection to determine the offline state of the user.

Usage guidelines

Use this command to set offline detection parameters specific to a MAC authentication user. To have this command take effect, you must make sure MAC authentication offline detection is enabled on the user's access port. The user-specific offline detection settings take effect on the online users immediately after they are configured.

Use this command as follows:

· Set an offline detect timer specific to a user and control whether to use the ARP snooping or ND snooping table to determine the offline state of the user.

¡ If the ARP snooping or ND snooping table is used, the device searches the ARP snooping or ND snooping table before it checks for traffic from the user within the detection interval. If a matching ARP snooping or ND snooping entry is found, the device resets the offline detect timer and the user stays online. If the offline detect timer expires because the device has not found a matching snooping entry for the user or received traffic from the user, the device disconnects the user.

¡ If the ARP or ND snooping table is not used, the device disconnects the user if it has not received traffic from that user before the offline detect timer expires.

When disconnecting the user, the device also notifies the RADIUS server (if any) to stop user accounting.

· Skip offline detection for the user. You can choose this option if the user is a dumb terminal. A dumb terminal might fail to come online again after it is logged off by the offline detection feature.

The device uses the offline detection settings for a user in the following sequence:

1. User-specific offline detection settings.

2. Offline detection settings assigned to the user by the RADIUS server. The settings include the offline detect timer, use of the ARP or ND snooping table in offline detection, and whether to ignore offline detection.

3. Port-based offline detection settings.

Examples

# Disable MAC authentication offline detection for the MAC authentication user with MAC address 000a-eb29-7511.

Usage guidelines

When you use this command on a port, follow these restrictions and guidelines:

· Make sure the port meets the following requirements:

¡ The port is configured with both 802.1X authentication and MAC authentication and performs MAC-based access control for 802.1X authentication.

¡ The port is enabled with the 802.1X unicast trigger.

· Do not enable MAC authentication delay on the port. This operation will delay MAC authentication after 802.1X authentication is triggered.

· To configure both 802.1X authentication and MAC authentication on the port, enable the 802.1X and MAC authentication features separately on the port.

Usage guidelines

Periodic MAC reauthentication enables the access device to periodically authenticate online MAC authentication users on a port. This feature tracks the connection status of online users and updates the authorization attributes assigned by the server, such as the ACL and VLAN.

To set the periodic reauthentication timer, use the mac-authentication timer reauth-period command in system view or in Ethernet interface view.

If periodic reauthentication is triggered for a user while that user is waiting for online synchronization, the system performs online synchronization and does not perform reauthentication for the user.

Default

Online user synchronization for MAC authentication is disabled. The device does not synchronize online MAC authentication user information on a port with a RADIUS server after the RADIUS server recovers from the unreachable state.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

Usage guidelines

IMPORTANT:

This command takes effect only when the device uses an IMC RADIUS server to authenticate MAC authentication users.

‌

To ensure that the RADIUS server maintains the same online MAC authentication user information as the device after the server state changes from unreachable to reachable, use this feature.

This feature synchronizes online MAC authentication user information between the device and the RADIUS server when the RADIUS server state is detected having changed from unreachable to reachable.

When synchronizing online MAC authentication user information on a port with the RADIUS server, the device initiates MAC authentication in turn for each authenticated online MAC authentication user to the RADIUS server.

If synchronization fails for an online user, the device logs off that user unless the failure occurs because the server has become unreachable again.

The amount of time required to complete online user synchronization increases as the number of online users grows. This might result in an increased delay for new MAC authentication users and users in the critical VLAN to authenticate or reauthenticate to the RADIUS server and come online.

To have this feature take effect, you must use it in conjunction with the RADIUS server status detection feature, which is configurable with the radius-server test-profile command. For more information about the RADIUS server status detection feature, see AAA configuration in User Access and Authentication Configuration Guide.

Parameters

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

reauth-period reauth-period-value: Sets the port-specific periodic MAC reauthentication timer in seconds. The value range is 60 to 7200.

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.

The device reauthenticates online MAC authentication users on a port at the specified periodic reauthentication interval if the port is enabled with periodic MAC reauthentication. To enable periodic MAC reauthentication on a port, use the mac-authentication re-authenticate command.

A change to the port-specific periodic reauthentication timer applies to online users only after the old timer expires.

The device selects a periodic reauthentication timer for MAC reauthentication in the following order:

1. Server-assigned reauthentication timer.

2. Port-specific reauthentication timer.

3. Global reauthentication timer.

4. Default reauthentication timer.

aging-time-value: Sets the user aging timer. The value range is 60 to 2147483647 seconds.

Usage guidelines

MAC authentication uses the following timers:

· Offline detect timer—Sets the interval that the device must wait 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. This timer takes effect only when the MAC authentication offline detection feature is enabled.

As a best practice, set the MAC address aging timer to the same value as the offline detect timer. This operation prevents a MAC authenticated user from being logged off within the offline detect interval because of MAC address entry expiration.

· 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.

· Periodic MAC reauthentication timer—Sets the interval at which the device reauthenticates online MAC authentication users on a port if the port is enabled with periodic MAC reauthentication. A change to the global periodic reauthentication timer applies to online users only after the old timer expires.

· 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 fails MAC authentication.

To avoid forced logoff before the server timeout timer expires, set the server timeout timer to a value that is lower than or equal to the product of the following values:

¡ The maximum number of RADIUS packet transmission attempts set by using the retry command in RADIUS scheme view.

¡ The RADIUS server response timeout timer set by using the timer response-timeout command in RADIUS scheme view.

For information about setting the maximum number of RADIUS packet transmission attempts and the RADIUS server response timeout timer, see AAA configuration in User Access and Authentication Configuration Guide.

· User aging timer (user-aging)—Sets the user aging timer for a type of access-limited VLAN for MAC authentication.

If you enable user aging for unthenticated MAC authentication user, you can set a user aging timer for MAC authentication critical or guest VLANs. The user aging timer for a type of access-limited VLAN for MAC authentication determines how long a user can stay in that type of VLAN.

For more information about how user aging operates, see the usage guidelines for the mac-authentication unauthenticated-user aging enable command.

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 of the shared account. If you do not specify a password for the shared account, the shared 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.

with-hyphen: Includes hyphens in a MAC address.

six-section: Specifies the six-section format. For example, xx-xx-xx-xx-xx-xx or XX-XX-XX-XX-XX-XX.

three-section: Specifies the three-section format. For example, xxxx-xxxx-xxxx or XXXX-XXXX-XXXX.

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

lowercase: Specifies letters in lower case.

uppercase: Specifies letters in upper case.

Usage guidelines

If you do not specify the six-section or three-section keyword, the MAC addresses in MAC-based user accounts are in six-section format.

If you specify the MAC-based user account format, the device uses the MAC address of a user as the username 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 the username.

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.

Parameters

profile-name: Specifies a profile name, a case-insensitive string of 1 to 31 characters.

Usage guidelines

To obtain MAC authentication user information from a RESTful server, create a profile for obtaining information from that server. A profile contains a set of parameters for accessing a RESTful server and the URI from which you obtain MAC authentication user information.

You can configure a maximum of 16 profiles for MAC authentication user recovery.

Examples

# Create a MAC authentication user recovery profile named profile1 and enter its view.

<Sysname> system-view

[Sysname] mac-authentication user-recovery-profile profile1

[Sysname-user-recovery-profile-profile1]

mac-authentication web-proxy

Use mac-authentication web-proxy to enable the device to trigger URL redirection for HTTP or HTTPS requests sent by a MAC authenticated user to a specified Web proxy port.

Use undo mac-authentication web-proxy to remove the specified or all Web proxy ports.

Syntax

mac-authentication web-proxy { http | https } port port-number

undo mac-authentication web-proxy { { http | https } port port-number | all-port }

Default

No Web proxy ports are specified. The device redirects the HTTP or HTTPS requests from a MAC authenticated user to the authorized URL only if the requests are sent from a browser with Web proxy disabled.

network-admin

Parameters

http: Specifies HTTP requests.

https: Specifies HTTPS requests.

port port-number: Specifies the TCP port number of a Web proxy for HTTP or HTTPS requests, in the range of 1 to 65535. The device always allows Web requests that use ports 80 and 443 to trigger MAC authentication URL redirection, and the two port numbers are not user configurable.

all-port: Specifies all Web proxy ports for MAC authentication URL redirection.

Usage guidelines

By default, the device discards the HTTP and HTTPS requests sent by a MAC authenticated user if they are sent from a browser configured with a Web proxy. To redirect the HTTP or HTTPS requests sent by a MAC authenticated user to a Web proxy port, add that Web proxy port to the device.

When you use this command, follow these restrictions and guidelines:

· You can specify a maximum of 64 Web proxy ports.

· Specify different Web proxy port numbers for HTTP and HTTPS requests.

· Adding or removing a Web proxy port will cause the device to log off all online MAC authenticated users that have been assigned an authorization redirect URL.

Examples

# Configure the device to trigger URL redirection for the HTTP requests sent by MAC authenticated users to Web proxy port 8080.

<Sysname> system-view

[Sysname] mac-authentication web-proxy http port 8080

Predefined user roles

network-admin

Parameters

ipv4-address: Specifies an IPv4 NAS IP address. The IPv4 address cannot be 0.0.0.0, 255.255.255.255, a class D address, a class E address, or a loopback address.

ipv6 ipv6-address: Specifies an IPv6 NAS IP address. The IPv6 address must be a unicast address and cannot be a loopback address or a link-local address.

Usage guidelines

The NAS IP address must be the same as that configured in the authentication RADIUS scheme for the MAC authentication users. In addition, it must be in the same IP address family as the IP address of the RESTful server in the profile.

You can specify only one NAS IP address in a profile. If you execute this command multiple times, the most recent configuration takes effect.

Examples

# In MAC authentication user recovery profile profile1, configure the device to use NAS IP address 10.1.1.1 to communicate with the RESTful server.

<Sysname> system-view

[Sysname] mac-authentication user-recovery-profile profile1

Syntax

reset mac-authentication access-user [ interface interface-type interface-number | mac mac-address | username username | vlan vlan-id ]

Views

User view

Predefined user roles

network-admin

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.

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 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.

The reset mac-authentication access-user command takes effect only on wired MAC authentication users. To log off wireless MAC authentication users, use the reset wlan client command. For more information about the reset wlan client command, see WLAN Access Command Reference.

Examples

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

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