Chapter 9 Wireless LAN Profiles

Table 31 Command Summary: Radio Profile (continued)

COMMAND

DESCRIPTION

beacon-interval <40..1000>

Sets the beacon interval for this profile.

 

When a wirelessly networked device sends a beacon, it

 

includes with it a beacon interval. This specifies the time

 

period before the device sends the beacon again. The

 

interval tells receiving devices on the network how long

 

they can wait in low-power mode before waking up to

 

handle the beacon. This value can be set from 40ms to

 

1000ms. A high value helps save current consumption of

 

the access point.

 

The default is 100.

 

 

[no] ampdu

Activates MPDU frame aggregation for this profile. Use

 

the no parameter to disable it.

 

Message Protocol Data Unit (MPDU) aggregation collects

 

Ethernet frames along with their 802.11n headers and

 

wraps them in a 802.11n MAC header. This method is

 

useful for increasing bandwidth throughput in

 

environments that are prone to high error rates.

 

By default this is enabled.

 

 

limit-ampdu< 100..65535>

Sets the maximum frame size to be aggregated.

 

By default this is 50000.

 

 

subframe-ampdu <2..64>

Sets the maximum number of frames to be aggregated

 

each time.

 

By default this is 32.

 

 

[no] amsdu

Activates MPDU frame aggregation for this profile. Use

 

the no parameter to disable it.

 

Mac Service Data Unit (MSDU) aggregation collects

 

Ethernet frames without any of their 802.11n headers and

 

wraps the header-less payload in a single 802.11n MAC

 

header. This method is useful for increasing bandwidth

 

throughput. It is also more efficient than A-MPDU except

 

in environments that are prone to high error rates.

 

By default this is enabled.

 

 

limit-amsdu <2290..4096>

Sets the maximum frame size to be aggregated.

 

The default is 4096.

[no] multicast-to-unicast

“Multicast to unicast” broadcasts wireless multicast traffic

 

to all wireless clients as unicast traffic to provide more

 

reliable transmission. The data rate changes dynamically

 

based on the application’s bandwidth requirements.

 

Although unicast provides more reliable transmission of

 

the multicast traffic, it also produces duplicate packets.

 

The no command turns multicast to unicast off to send

 

wireless multicast traffic at the rate you specify with the

 

2g-multicast-speed or 5g-multicast-speed

 

command.

[no] block-ack

Makes block-ackactive or inactive. Use the no

 

parameter to disable it.

ch-width wlan_htcw

Sets the channel width for this profile.

guard-interval wlan_htgi

Sets the guard interval for this profile.

 

The default for this is short.

 

 

2g-basic-speedwlan_2g_basic_speed

Sets the 2.4 GHz basic band rates.

 

The default is 1.0 2.0 5.5 11.0.

 

 

80
