Parameters

ac-vo: Specifies the AC-VO (voice traffic) queue.

ac-vi: Specifies the AC-VI (video traffic) queue.

ac-be: Specifies the AC-BE (best-effort traffic) queue.

ac-bk: Specifies the AC-BK (background traffic) queue.

all: Specifies all the EDCA parameters.

noack: Specifies the AC queue to use the No ACK policy. The protocol defines two ACK policies: Normal ACK and No ACK.

txoplimit-value: Specifies the TXOPLimit parameter of EDCA. The range of this value (in units of 32 microseconds) varies with the device model of the AP configured on the AC. The TXOP value of 0 indicates that only one MPDU can be transmitted. The range of this argument is limited by the radio chip capability.

ecwmin-value: Specifies the ECWmin parameter of EDCA. The range of this value varies with the device model of the AP configured on the AC. The range of this argument is limited by the radio chip capability.

ecwmax-value: Specifies the ECWmax parameter of EDCA. The range of this value varies with the device model of the AP configured on the AC. The range of this argument is limited by the radio chip capability.

aifsn-value: Specifies the AIFSN parameter of EDCA. The range of this value varies with the device model of the AP configured on the AC. The range of this argument is limited by the radio chip capability.

Usage guidelines

For a description of each EDCA parameter, see WLAN Configuration Guide.

ECWmin must be no greater than ECWmax. The two parameters must be enabled or disabled simultaneously.

When an AP uses 802.11b radio cards, H3C recommends that you set TXOPLimit values of the AC-BK, AC-BE, AC-VI, and AC-VO queues to 0, 0, 188, and 102, respectively.

Examples

# Set AIFSN to 2 for the AC-VO queue in radio policy radio1.

<Sysname> system-view

[Sysname] wlan radio-policy radio1

[Sysname-wlan-rp-radio1] wmm edca radio ac-vo aifsn 2

wmm edca client (ac-vo and ac-vi)

Use wmm edca client to set EDCA parameters for the AC-BE or AC-BK queue for clients.

Use undo wmm edca client to restore the default of the specified or all EDCA parameters for the specified AC queue.

Syntax

wmm edca client { ac-vo | ac-vi } { aifsn aifsn-value | ecw ecwmin ecwmin-value ecwmax ecwmax-value | txoplimit txoplimit-value | cac } *

undo wmm edca client { ac-vo | ac-vi } { aifsn | ecw | txoplimit | cac | all }

Default

Table 7 lists the default EDCA parameters of the AC-VI and AC-VO queue for clients.

2: System level

Parameters

ac-vo: Specifies the AC-VO (voice traffic) queue.

ac-vi: Specifies the AC-VI (video traffic) queue.

all: Specifies all EDCA parameters.

cac: Enables CAC. The AC-VO and AC-VI queues support CAC, which is disabled by default. The AC-BE and AC-BK queues do not support CAC.

aifsn-value: Specifies the AIFSN parameter of EDCA, which is in the range of 2 to 15.

ecwmin-value: Specifies the ECWmin parameter of EDCA, which is in the range of 0 to 15.

ecwmax-value: Specifies the ECWmax parameter of EDCA, which is in the range of 0 to 15.

txoplimit-value: Specifies the TXOPLimit parameter of EDCA, which is in the range of 0 to 65535 (in units of 32 microseconds). The TXOP value of 0 indicates that only one MPDU can be transmitted.

Usage guidelines

For a description of each EDCA parameter, see WLAN Configuration Guide.

ECWmin must not be greater than ECWmax. The two parameters must be enabled or disabled simultaneously.

When all the clients are 802.11b terminals, H3C recommends that you set the TXOPLimit to 188 and 102 for the AC-VI and AC-VO queues, respectively.

If both 802.11b and 802.11g clients are present, H3C recommends that you use the default TXOPLimit settings in Table 7.

If CAC is enabled for an AC queue, CAC is also enabled for AC queues with higher priority. For example, if you use the wmm edca client command to enable CAC for the AC-VI queue, CAC is also enabled for the AC-VO queue. However, enabling CAC for the AC-VO queue does not enable CAC for the AC-VI queue.

Examples

# Set AIFSN to 3 for the AC-VO queue.

<Sysname> system-view

[Sysname] wlan radio-policy radio1

[Sysname-wlan-rp-radio1] wmm edca client ac-vo aifsn 3

wmm edca client (ac-be and ac-bk)

Use wmm edca client to set the EDCA parameters of the AC-VO or AC-VI queue for the clients in a BSS.

Use undo wmm edca client to restore the default.

Syntax

wmm edca client { ac-be | ac-bk } { aifsn aifsn-value | ecw ecwmin ecwmin-value ecwmax ecwmax-value | txoplimit txoplimit-value } *

undo wmm edca client { ac-be | ac-bk } { aifsn | ecw | txoplimit | all }

Default

Parameters

ac-be: Specifies the AC-BE (best-effort traffic) queue.

ac-bk: Specifies the AC-BK (background traffic) queue.

all: Specifies all the EDCA parameters.

aifsn-value: Specifies the AIFSN parameter of EDCA, which is in the range of 2 to 15.

ecwmin-value: Specifies the ECWmin parameter of EDCA, which is in the range of 0 to 15.

ecwmax-value: Specifies the ECWmax parameter of EDCA, which is in the range of 0 to 15.

txoplimit-value: Specifies the TXOPLimit parameter of EDCA, which is in the range of 0 to 65535 (in units of 32 microseconds). The TXOP value of 0 indicates that only one MPDU can be transmitted.

Usage guidelines

For a description of each EDCA parameter, see WLAN Configuration Guide.

ECWmin must not be greater than ECWmax. The two parameters must be enabled or disabled simultaneously.

When all the clients are 802.11b terminals, H3C recommends that you set the TXOPLimit value to 0 for both the AC-BK and AC-BE queues.

If both 802.11b and 802.11g clients are present, H3C recommends that you use the default TXOPLimit settings for the AC-BK and AC-BE queues.

Examples

# Set AIFSN to 3 for the AC-BE queue.

<Sysname> system-view

[Sysname] wlan radio-policy radio1

[Sysname-wlan-rp-radio1] wmm edca client ac-be aifsn 5

wmm enable

Use wmm enable to enable the WMM function.

Use undo wmm enable to disable the WMM function.

Syntax

wmm enable

undo wmm enable

Default

The WMM function is enabled.

Usage guidelines

The 802.11n protocol stipulates that all 802.11n clients support WLAN QoS. Therefore, when the radio operates in 802.11an or 802.11gn mode, you should enable WMM. Otherwise, the associated 802.11n clients will operate in 802.11a or 802.11g mode.

Examples

# Disable the WMM function.

<Sysname> system-view

[Sysname] wlan radio-policy radio1

[Sysname-wlan-rp-radio1] undo wmm enable

wmm svp map-ac

Use wmm svp map-ac to map SVP packets to a specific AC queue.

Use undo wmm svp map-ac to restore the default.

Syntax

wmm svp map-ac { ac-vo | ac-vi | ac-be | ac-bk }

undo wmm svp map-ac

Default

SVP packet mapping is disabled.

Parameters

ac-vo: Specifies the AC-VO (voice traffic) queue.

ac-vi: Specifies the AC-VI (video traffic) queue.

ac-be: Specifies the AC-BE (best-effort traffic) queue.

ac-bk: Specifies the AC-BK (background traffic) queue.

Usage guidelines

H3C recommends that you map SVP packets to the AC-VO queue in normal cases.

Examples

# Map SVP packets to the AC-VO queue.
