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-limit limit is met, but do not
fragment packets
exact-size - put as much packets as possible in one frame, until the framer-limit limit 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

Nstreme2 Group Settings
Submenu level: /interface wireless nstreme-dual
Description
Two radios in nstreme-dual-slave mode 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-limit limit is met, but do not
fragment packets
exact-size - put as much packets as possible in one frame, until the framer-limit limit 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
