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 that use 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.

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

· Do not use this command in conjunction with the following features:

¡ Free VLANs for port security.

¡ MAC authentication guest VLAN or guest VSI. The device cannot perform MAC authentication for a user once that user is added to the MAC authentication guest VLAN or guest VSI.

· 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 Ten-GigabitEthernet 1/1/1.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/1/1

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

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.

On a port, the MAC authentication critical VLAN configuration is mutually exclusive with the MAC authentication guest VSI and MAC authentication critical VSI settings.

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 Ten-GigabitEthernet 1/1/1.

Parameters

critical-vsi-name: Specifies the name of the MAC authentication critical VSI on the port, a case-sensitive string of 1 to 31 characters.

url-user-logoff: Logs off MAC authentication users that have been assigned authorization URLs on the port when the first user is assigned to the critical VSI. If you do not specify this keyword, the device keeps these MAC authentication users online until no packets are received from the users within the offline detect interval.

Usage guidelines

The MAC authentication critical VSI accommodates users that have failed MAC authentication because all the servers in their ISP domains are unreachable. Users in the critical VSI can access only network resources in the VXLAN associated with this VSI.

You can configure only one MAC authentication critical VSI on a port. The MAC authentication critical VSIs on different ports can be different.

On a port, the MAC authentication critical VSI configuration is mutually exclusive with the MAC authentication guest VLAN and MAC authentication critical VLAN settings.

Parameters

guest-vsi-name: Specifies the name of the MAC authentication guest VSI on the port, a case-sensitive string of 1 to 31 characters.

Usage guidelines

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

You can configure only one MAC authentication guest VSI on a port. The MAC authentication guest VSIs on different ports can be different.

On a port, the MAC authentication guest VSI configuration is mutually exclusive with the MAC authentication guest VLAN and MAC authentication critical VLAN settings.

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.

network-admin

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.

<Sysname> system-view

[Sysname] mac-authentication offline-detect mac-address 000a-eb29-7511 ignore

Usage guidelines

When you configure 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.

· For the port to perform MAC authentication before it is assigned to the 802.1X guest VLAN or guest VSI, use the dot1x guest-vlan-delay new-mac or dot1x guest-vsi-delay new-mac command to delay assigning the port to the 802.1X guest VLAN or guest VSI.

For information about the dot1x guest-vlan-delay new-mac or dot1x guest-vsi-delay new-mac command, see "802.1X commands."

· 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, use one of the following methods:

¡ Enable the 802.1X and MAC authentication features separately on the port.

¡ Enable port security on the port. The port security mode must be userlogin-secure-or-mac or userlogin-secure-or-mac-ext.

For information about port security mode configuration, see port security in Security 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.

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."

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.

Examples

# Enable MAC authentication delay on Ten-GigabitEthernet 1/1/1 and set the delay time to 10 seconds.

guest-vsi: Specifies MAC authentication guest VSIs.

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 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. 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.

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

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

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

Do not set the user aging timer for users in MAC authentication guest VLANs or VSIs to an integral multiple of the authentication interval for them. If you do so, the aging timer will not take effect. The authentication interval for MAC authentication users in a guest VLAN or VSI is configurable with the mac-authentication guest-vlan auth-period command or the mac-authentication guest-vsi auth-period command, respectively

Usage guidelines

User aging for unauthenticated MAC authentication users applies to users added to a MAC authentication guest or critical VLAN or VSI because they have not been authenticated or have failed authentication.

When a user in one of those VLANs or VSIs ages out, the device removes the user from the VLAN or VSI and deletes the MAC address entry for the user from the access port.

For users in one of those VLANs or VSIs on one port to be authenticated successfully and come online on another port, enable this feature. In any other scenarios, disable this feature as a best practice.

network-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.

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, for example xx-xx-xx-xx-xx-xx.

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