overhead (and thus increase speed). The card is not waiting for frames, but in case a number of packets are queued for transmitting, they can be combined. There are several methods of framing:

none - do nothing special, do not combine packets (framing is disabled)

best-fit- put as much packets as possible in one frame, until the framer-limitlimit is met, but do not fragment packets

exact-size- put as much packets as possible in one frame, until the framer-limitlimit is met, even if fragmentation will be needed (best performance)

dynamic-size- choose the best frame size dynamically name (name) - reference name of the interface

￿

The settings here (except for enabling nstreme) are relevant only on Access Point, they are ignored for client devices! The client automatically adapts to the AP settings. WDS for Nstreme protocol requires using station-wds mode on one of the peers. Configurations with WDS between AP modes (bridge and ap-bridge) will not work.

Example

To enable the nstreme protocol on the wlan1 radio with exact-size framing:

[admin@AT-WR4562] interface wireless nstreme> print

0 name="wlan1" enable-nstreme=no enable-polling=yes disable-csma=no framer-policy=none framer-limit=3200

[admin@AT-WR4562] interface wireless nstreme> set wlan1 enable-nstreme=yes \ \... framer-policy=exact-size

4.3.4 Nstreme2 Group Settings

Submenu level: /interface wireless nstreme-dual

Description

Two radios in nstreme-dual-slavemode can be grouped together to make nstreme2 Point-to-Point connection. To put wireless interfaces into a nstreme2 group, you should set their mode to nstreme- dual-slave. Many parameters from /interface wireless menu are ignored, using the nstreme2, except:

•frequency-mode

•country

•antenna-gain

•tx-power

•tx-power-mode

•antenna-mode

Property Description

arp (disabled enabled proxy-arp reply-only; default: enabled) - Address Resolution Protocol setting

disable-csma(yes no; default: no) - disable CSMA/CA (better performance) disable-running-check(yes no) - whether the interface should always be treated as running even if there is no connection to a remote peer

framer-limit(integer; default: 2560) - maximal frame size

framer-policy(none best-fit exact-size; default: none) - the method how to combine frames. A number of frames may be combined into one bigger one to reduce the amout of protocol overhead (and thus increase speed). The card are not waiting for frames, but in case a number packets are queued for transmitting, they can be combined. There are several methods of framing:

none - do nothing special, do not combine packets

best-fit- put as much packets as possible in one frame, until the framer-limitlimit is met, but do not fragment packets

exact-size- put as much packets as possible in one frame, until the framer-limitlimit is met, even if fragmentation will be needed (best performance)

mac-address(read-only: MAC address) - MAC address of the transmitting wireless card in the set
