address-security cache

Use address-security cache to set the aging timer for address security entries.

Use undo address-security cache to restore the default.

Syntax

address-security cache { ipv4-aging-time aging-time | ipv6-aging-time aging-time }

undo address-security cache { ipv4-aging-time | ipv6-aging-time }

Default

The aging timer is 14400 seconds for IPv4 entries and 604800 seconds for IPv6 entries.

Views

WLAN roaming center view

Predefined user roles

network-admin

Parameters

ipv4-aging-time: Specifies IPv4 address security entries.

ipv6-aging-time: Specifies IPv6 address security entries.

aging-time: Specifies the aging timer. The value range is 600 to 86400 seconds for IPv4 entries and 600 to 1296000 seconds for IPv6 entries.

Usage guidelines

Client roaming centers generate address security entries at client associations to record client MAC address, IP address, and username information, and synchronize the entries to the WLAN roaming center. When the aging timer of an entry expires, the client roaming center deletes the entry.

As a best practice, set an aging time not larger than the lease of IP addresses assigned to clients by the DHCP server.

Examples

# Set the aging timer of IPv4 address security entries to 600 seconds.

<Sysname> system-view

[Sysname] wlan roaming-center

[Sysname-wlan-roaming-center] address-security cache ipv4-aging-time 600

Related commands

address-security enable

address-security enable

Use address-security enable to enable address security.

Use undo address-security enable to disable address security.

Syntax

address-security enable [ alarm-only ]

undo address-security enable

Default

Address security is disabled.

Views

Service template view

Predefined user roles

network-admin

Parameters

alarm-only: Configures address security to generate alarms only and not to limit client access.

Usage guidelines

This feature enables the WLAN roaming center to check clients coming online from the specified service template for MAC address or IP address spoofing attacks. If a MAC or IP address spoofing attack is detected, the AC adds the attacker to the blacklist, and logs off both the attacker and the client whose address is spoofed.

For WLAN address security to take effect, configure 802.1X authentication.

WLAN address security takes effect only on clients that come online afterwards.

Examples

# Enable address security on service template 1.

<Sysname> system-view

[Sysname] wlan service-template 1

[Sysname-wlan-st-1] address-security enable

client ip-cache aging-time

Use client ip-cache aging-time to set the aging time for client IP address cache entries.

Use undo client ip-cache aging-time to restore the default.

Syntax

client ip-cache aging-time aging-time

undo client ip-cache aging-time

Default

The aging time is 1800 seconds for client IP address cache entries.

Views

WLAN roaming center view

Predefined user roles

network-admin

Parameters

aging-time: Specifies the aging time for client IP address cache entries, in the range of 600 to 86400 seconds.

Usage guidelines

With IP address recovery enabled for reassociated clients, the WLAN roaming center maintains IP and MAC binding entries for clients that leave an AP. When the aging time of such a cache entry expires, the WLAN roaming center deletes the entry.

Examples

# Set the aging time for client IP address cache entries to 600 seconds.

<Sysname> system-view

[Sysname] wlan roaming-center

[Sysname-wlan-roaming-center] client ip-cache aging-time 600

Related commands

control-access

Use control-access to specify a portal roaming center or client roaming center permitted by the WLAN roaming center.

Use undo control-access to restore the default.

Syntax

control-access { bas-ip ipv4-address | bas-ipv6 ipv6-address }

undo control-access { bas-ip ipv4-address | bas-ipv6 ipv6-address }

Default

No permitted portal roaming center or client roaming center is specified.

Views

Predefined user roles

network-admin

Parameters

bas-ip ipv4-address: Specifies the IPv4 address of a portal roaming center or client roaming center.

bas-ipv6 ipv6-address: Specifies the IPv6 address of a portal roaming center or client roaming center.

Usage guidelines

This feature enables the WLAN roaming center to process packets from only the permitted portal or client roaming centers, enhancing network security. If no permitted portal roaming centers are specified, the WLAN roaming center processes packets from all portal roaming centers.

In inter-AC roaming of portal users, you can execute this command multiple times to specify multiple portal or client roaming centers. You can specify both IPv4 addresses and IPv6 addresses of portal or client roaming centers.

Examples

# Specify the AC with an IP address of 111.8.33.72 as a portal or client roaming center permitted by the WLAN roaming center.

Predefined user roles

network-admin

Parameters

port-number: Specifies a port number in the range of 1 to 65534. Make sure the specified port is not in use and does not use a well-known port number.

Usage guidelines

Make sure the port specified for the WLAN roaming center is the same as the port specified for portal roaming centers and client roaming centers.

Changing the port number when portal clients are online might cause information synchronization failure between the WLAN roaming center and portal roaming centers. Portal clients might fail to roam and must be reauthenticated.

As a best practice to avoid data residual, disable the WLAN roaming center before you change the port number.

Examples

# Configure the WLAN roaming center to use port 60015 to communicate with portal roaming centers and client roaming centers.

Predefined user roles

network-admin

Parameters

timeout: Specifies the timeout timer in the range of 1 to 10 seconds.

Usage guidelines

In inter-AC roaming, when a portal user goes offline, it informs the associated portal roaming center, which then informs the WLAN roaming center. Then, the WLAN roaming center informs the other portal roaming centers. If the WLAN roaming center fails to receive a response from a portal roaming center before the response timeout timer expires, it retransmits the packet. If it fails to receive any response from a portal roaming center after the last retransmission attempt, it deletes the timeout timer.

In a WLAN configured with WLAN address security, the WLAN roaming center sends requests to client roaming centers to query the aging time of MAC address and IP address entries. If it fails to receive a response before the response timeout timer expires, it deletes the specific MAC address and IP address entry.

Examples

# Set the response timeout timer to 2 seconds for packets to portal or client roaming centers.

<Sysname> system-view

[sysname] wlan roaming-center

[Sysname-wlan-roaming-center] response-timeout 2

retry

Use retry to set the maximum transmission attempts for user offline notification requests.

Use undo retry to restore the default.

Syntax

retry retries

undo retry

Default

The maximum number of transmission attempts for user offline notification requests is 5.

Views

Predefined user roles

network-admin

Parameters

retries: Specifies the maximum number of packet transmission attempts in the range of 1 to 10.

Usage guidelines

After sending a user offline notification request to an AC, the WLAN roaming center resends the request if it fails to receive a response before the wait timer expires. If it fails to receive any response after the maximum transmission attempt limit is reached, the WLAN roaming center deletes the timeout timer and removes the AC from the access device list of the client.

Examples

# Set the maximum transmission attempts for user offline notification requests to 4.

<Sysname> system-view

[Sysname] wlan roaming-center

[Sysname-wlan-roaming-center] retry 4

Related commands

Usage guidelines

For portal users to roam between ACs, you must enable portal roaming center on both ACs.

You can enable the WLAN roaming center on only one AC in a network.

Disabling the WLAN roaming center feature deletes all portal client information.

To use WLAN address security, you must enable the WLAN roaming center.

Examples

# Enable the WLAN roaming center.

<Sysname> system-view

[Sysname] wlan roaming-center

[Sysname-wlan-roaming-center] roaming-center enable

spoofing-attack blacklist

Use spoofing-attack blacklist to add a client to the spoofing attack blacklist by username.

Use undo spoofing-attack blacklist to delete a client from the spoofing attack blacklist.

Syntax

Predefined user roles

network-admin

Parameters

username username: Specifies the username of a user, a case-sensitive string of 1 to 55 characters. The name cannot be a, al, or all, and cannot contain domain names or the following special characters: \ | / : * ? < > @

Usage guidelines

With address security configured, the WLAN roaming center logs off both the detected MAC or IP address spoofing attackers and the spoofed clients, and adds the attackers to the blacklist. This prevents attackers from coming online again.

You can add a maximum of 5000 clients to the spoofing attack blacklist.

The spoofing attack blacklist takes effect only on the WLAN roaming center.

Examples

# Add the client with username user1 to the spoofing attack blacklist.

<Sysname> system-view

[Sysname] wlan address-security

[Sysname-wlan-address-security] spoofing-attack blacklist username user1
