display wlan multicast optimization

Use display wlan multicast optimization to display multicast optimization information.

Syntax

display wlan multicast optimization interface wlan-radio [ radio-number ] [ | { begin | exclude | include } regular-expression ]

Views

Any view

Default command level

1: Monitor level

Parameters

wlan-radio radio-number: Specifies a radio interface by its number. If you do not specify the radio-number argument, the command displays multicast optimization information for all radio interfaces.

|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays all lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Examples

# Display multicast optimization information for the radio interface WLAN-Radio 1/0/2.

<Sysname> display wlan multicast optimization interface wlan-radio 1/0/2

                      Multicast Optimization Information

Table 1 Command output

Field	Description
Total clients	Total number of clients served by multicast optimization. If a client joins multiple multicast groups, the client is counted as multiple clients. For example, if a client has joined two multicast groups through a radio, the client is counted as two clients by multicast optimization.
Action	Operating status of the multicast optimization function: ·         Optimize—The multicast optimization function is operating. ·         Halt—The multicast optimization function is halted.
Multicast Address	Address of the multicast group that the clients has joined.
MAC Address	MAC addresses of the clients that have joined the multicast group.

 

multicast optimization enable

Use multicast optimization enable to enable multicast optimization.

Use undo multicast optimization enable to restore the default.

Syntax

multicast optimization enable

undo multicast optimization enable

Default

Multicast optimization is disabled.

Views

Default command level

2: System level

Examples

# Enable multicast optimization for service template 1.

<Sysname> system-view

[Sysname] wlan service-template 1 clear

[Sysname-wlan-st-1] multicast optimization enable

wlan multicast optimization aging-time

Use wlan multicast optimization aging-time to configure the aging time for multicast optimization entries.

Use undo wlan  multicast optimization aging-time to restore the default.

Syntax

wlan multicast optimization aging-time time

undo wlan multicast optimization aging-time

Default

The aging time for multicast optimization entries is 260 seconds.

Views

Default command level

2: System level

Parameters

time: Specifies the aging time for multicast optimization entries, in the range of 200 to 1000 seconds.

Usage guidelines

If the AP does not receive any IGMP report from a client within the aging time, the AP removes the client from the multicast optimization entry.

Examples

# Configure the aging time for multicast optimization entries as 300 seconds.

<Sysname> system-view

[Sysname] wlan multicast optimization aging-time 300

wlan multicast optimization threshold

Use wlan multicast optimization threshold to configure the maximum number of clients supported by multicast optimization.

Use undo wlan multicast optimization threshold to restore the default.

Syntax

wlan multicast optimization threshold threshold-value

undo wlan multicast optimization threshold

Default

The maximum number of clients supported by multicast optimization is 6.

Views

System view

Default command level

2: System level

Parameters

threshold-value: Specifies the maximum number of clients supported by multicast optimization, in the range of 2 to 124.

Usage guidelines

A client can join up to eight multicast groups.

If a client joins multiple multicast groups, the client is counted as multiple clients in multicast optimization statistics. For example, if a client has joined two multicast groups, the client is counted as two clients in the multicast optimization statistics.

Examples

# Configure the maximum number of clients allowed for multicast optimization as 7.

<Sysname> system-view

[Sysname] wlan multicast optimization threshold 7

wlan multicast optimization threshold-action

Use wlan multicast optimization threshold-action to configure the action to take when the maximum number of clients supported multicast optimization is reached.

Use undo wlan multicast optimization threshold-action to restore the default.

Syntax

wlan multicast optimization threshold-action { halt | reject-client }

undo wlan multicast optimization threshold-action

Default

The multicast optimization function becomes invalid when the maximum number of clients supported multicast optimization is reached.

Views

System view

Default command level

2: System level

Parameters

halt: Invalidates the multicast optimization feature. A new client can join a multicast group and receive multicast packets, and a multicast optimization entry can be created for the client. However, the multicast optimization feature for all clients in the multicast group becomes invalid. When the number of clients drops below the upper limit, the multicast optimization feature takes effect again.

reject-client: Rejects new clients. A new client can join a multicast group, but no new multicast optimization entries can be created. If multicast optimization entries have been created for other clients in the multicast group, the client cannot receive multicast packets. If not, the client can receive multicast packets.

Usage guidelines

If you configure the halt mode first, and then configure the reject mode, the existing multicast optimization entries still take effect.

Examples

# Configure the AP to reject new clients when the maximum number of clients supported multicast optimization is reached.

<Sysname> system-view

[Sysname] wlan multicast optimization threshold-action reject-client
