WLAN high availability commands

Dual-link backup commands

backup-ac

Use backup-ac to specify a backup AC.

Use undo backup-ac to remove the backup AC configuration.

Syntax

backup-ac { ip ipv4-address | ipv6 ipv6-address }

undo backup-ac { ip | ipv6 }

Default

In AP view, an AP uses the configuration in AP group view.

In AP group view, no backup AC is specified.

Parameters

ip ip-address: Specifies a backup AC by its IPv4 address.

ipv6 ipv6-address: Specifies a backup AC by its IPv6 address.

Usage guidelines

You can specify only one IPv4 address or one IPv6 address in either AP view or AP group view.

The configuration in AP view takes precedence over the configuration in AP group view. If you execute the undo command in AP view, the backup AC specified in AP group view will be used.

Executing the undo command also terminates the backup CAPWAP tunnel.

Examples

# Specify a backup AC for AP ap1.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA6320

[Sysname-wlan-ap-ap1] backup-ac ip 192.168.1.1

# Specify a backup AC for AP group group1.

<Sysname> system-view

[Sysname] wlan ap-group 1

[Sysname-wlan-ap-group-1] backup-ac ip 192.168.1.1

client-persistence enable

Use client-persistence enable to enable client persistence.

Use undo client-persistence enable to restore the default.

Syntax

client-persistence enable

undo client-persistence enable

Default

Client persistence is disabled.

Usage guidelines

In a dual-link network, when the backup AC becomes the master AC, it synchronizes all client entries with the master AC. During the synchronization, wireless clients will go offline simultaneously and it will take a long time for them to come online again. With this feature enabled, the backup AC synchronizes entries with the master AC slowly, allowing wireless clients to slowly go offline and come online, thereby keeping clients online.

To use this feature together with portal authentication, configure MAC-based quick portal authentication for users to complete authentication without awareness.

Examples

# Enable client persistence.

<Sysname> system-view

[Sysname] wlan global-configuration

[Sysname-wlan-global-configuration] client-persistence enable

display wlan persistent-client

Use display wlan persistent-client to display information about clients kept online by client persistence.

Usage guidelines

AP backup enables the active AC (master AC) in an IRF fabric to synchronize information about connected APs to all the non-active ACs. When the active AC fails, one of the non-active ACs becomes active to provide services, ensuring service continuity.

This feature does not take effect on online APs. Disabling this feature removes backup AP information from all ACs.

Examples

# Enable AP backup.

<Sysname> system-view

[Sysname] wlan ap-backup hot-backup enable global

Usage guidelines

For this command to take effect, make sure AP backup is enabled.

After client backup is enabled, an active AC backs up information about associated clients to other member ACs. When the active AC fails, the associated clients can associate with another member AC so that the clients are always online. Client backup is triggered every time client information changes.

This command takes effect only on clients that come online after client backup is enabled. Disabling client backup deletes client backup information from all member ACs.

Examples

# Enable client backup.

<Sysname> system-view

[Sysname] wlan client-backup hot-backup enable

wlan client-backup hot-backup delay

Use wlan client-backup hot-backup delay to set the client backup delay.

Use undo wlan client-backup hot-backup delay to restore the default.

Syntax

wlan client-backup hot-backup delay delay-time

undo wlan client-backup hot-backup delay

Default

The client backup delay is 60 seconds.

delay-time: Specifies the client backup delay time in the range of 0 to 300 seconds. If you set the delay time to 0, the AC backs up information changes about associated clients to other ACs in real time.

Parameters

This feature takes effect only when client backup is enabled.

This command takes effect only on clients that come online after the client backup delay is set.

If an active/standby switchover occurs during the delay time, online clients whose information has not been backed up will be logged off and need to come online again. An active/standby switchover can be triggered by a restart of the active AC process.

Examples

# Set the client backup delay to 240 seconds.

<System> system-view

[System] wlan client-backup hot-backup delay 240

network-operator

Parameters

instance-name: Specifies a WLAN VSRP instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a WLAN VSRP instance, this command displays information about all WLAN VSRP instances.

Examples

# Display information about WLAN VSRP instance abc.

<Sysname> display wlan client vsrp instance abc

VSRP instance name     : abc

Instance peer address  : 1.1.1.1

Instance status        : Master

Tunnel status          : Checking

Table 6 Command output

Field

Description

Instance peer address

Peer IP address of the TCP connection.

Instance status

VSRP instance state:

·     Master—The device acts as the master in the VSRP instance.

·     Backup—The device acts as the backup in the VSRP instance.

·     Down—The device is not running in the VSRP instance.

Tunnel status

Backup data tunnel state:

·     Up—The tunnel is in up state and can be used for data backup.

·     Down—The tunnel is in down state and cannot be used for data backup.

·     Checking—Checking AP BSS information at both ends of the tunnel. If the information is consistent, the system can perform data backup for wireless clients. If the information is inconsistent, the system cannot perform data backup for wireless clients.

Created at

Time at which the VSRP instance is associated with the AC.

client vsrp-port

Use client vsrp-port to specify a TCP port number for WLAN VSRP to establish the data channel for wireless client data backup.

Use undo client vsrp-port to restore the default.

Syntax

client vsrp-port port-number

undo client vsrp-port

Default

TCP port 60048 is used to establish the data channel for wireless client data backup.

Predefined user roles

network-admin

Parameters

port-number: Specifies a TCP port number in the range of 1025 to 65535. The TCP port cannot be used by other services or be a well-known port.

Usage guidelines

To back up wireless client data, the device must establish a TCP data channel with the peer device. You can use this command to change the TCP port number for establishing the data channel. After you change the port number, the device disconnects the data channel and then reestablishes it by using the new port number.

Examples

# Specify TCP port 20000 for VSRP to establish the data channel for wireless client data backup.

<Sysname> system-view

[Sysname] wlan global-configuration

[Sysname-wlan-global-configuration] client vsrp-port 20000

vsrp-instance (Global configuration view)

vsrp-instance (Global configuration view)

Use vsrp-instance to associate the AC with a VSRP instance.

Use undo vsrp-instance to restore the default.

Syntax

vsrp-instance vsrp-instance-name

undo vsrp-instance

Default

The AC is not associated with any VSRP instance.

Parameters

vsrp-instance-name: Specifies a VSRP instance by its name, a case-sensitive string of 1 to 31 characters.

Usage guidelines

WLAN VSRP establishes a data backup tunnel between the master AC and backup AC for real-time synchronization of WLAN service data. If the master AC or the link to the master AC fails, the backup AC takes over services to ensure service continuity. After the switchover, online clients can still access network resources without being reauthenticated and client accounting and authorization information is retained.

Make sure the master AC and backup AC are associated with the same VSRP instance.

Examples

# Associate the AC with VSRP instance abc.

<Sysname> system-view

[Sysname] wlan global-configuration

[Sysname-wlan-global-configuration] vsrp-instance abc
