mode {11a | 11g} Specifies the operational mode of wireless interface
(11a | 11g). By default, 11a is specified for 802.11a
interfaces (radio1-1 and radio1-2) and 11g is specified
for 802.11bg interfaces (radio2-1 and radio2-2).
When changing the mode, be sure to also change the
rate to correspond.
rate {1 | 2 | 5.5 | 6 | 9 | 11 | 12 | 18 |
24 | 36 | 48 | 54 | auto}
Specifies the transmit data rate (Mbps) of the interface.
By default, auto is set to allow the rate to be set by the
interface mode. Specifically:
z 802.11a supports 6 | 9 | 12 | 18 | 24 | 36 | 48 | 54 | auto
z 802.11b supports 1 | 2 | 5.5 | 11 | auto
z 802.11bg supports 1 | 2 | 5.5 | 6 | 9 | 11 | 12 | 18 | 24 |
36 | 48 | 54 | auto
channel {1-11 | 36 | 40 | 44 | 48 | 52
| 56 | 60 | 64 | 149 | 153 | 157 | 161 |
165}
Specifies the channel (frequency) on which wireless
interface is operating. By default, channel 36 is set for
radio1-1 and 149 for radio1-2 (11a interfaces), and
channel 1 is set for radio2-1 and 11 for radio2-2
(11b/11bg interfaces).
For this release of product, following channel usage is
recommended:
For 802.11bg radios:
z Channel 1 and Channel 11
For 802.11a radios, use any of the following
combinations:
z Channel 36 and Channel 48
z Channel 40 and Channel 52
z Channel 44 and Channel 56
z Channel 48 and Channel 60
z Channel 52 and Channel 64
short_preamble {enable | disable} Specifies whether to enable or disable short preamble.
By default, short preamble can only be enabled if mode
is set to 11g. If short preamble is disabled, long
preamble is used, which may be necessary to ensure
compatibility between the RS and some older WLAN
cards. Using short preamble improves throughput.
stx_power 1-30 Specifies the transmit power level in dBm for the
interface. By default, the power level is set to 30 dBm.
ess_vlantag 0-4094 Specifies the VLAN identification tag to assign to the
interface. Valid tags can be from 0 to 4094. The default
setting is 0.
