E.2 Settings to reduce DHCP and ARP traffic on air
Use these commands to reduce on air DHCP and ARP traffic.
This command enables the sniffing DHCP packets to update the the MU table and keeping it current. From the (config-
wireless) context, issue this command.
dhcp-sniff-state enable
This command sends DHCP packets only to the AP on which the MU that requested DHCP is located. DHCP packets are
not sent to the other APs.
dhcp-one-portal-forward enable
This command prevents sending boradcast/multicast packets to APs that do not have any MUs.
no service wireless idle-radio-send-multicast enable
This commands prevents sending ARP packets for unknown device over air.
proxy-arp enable strict
E.3 Settings to set the rate at which multicast and broadcast packets are sent
By default, multicast and broadcast packets are sent at the highest basic rate. Though this increases the transmission
rate, the range is restricted. To increase the range, use the range parameter.
To configure to send these packets at a lower rate issue this command:
broadcast-tx-speed [range|throughput]
range
throughput
Depending on your requirement, select the appropriate action to increase your performance.
E.4 Remove DFS channels from ACS
Removing the Dynamic Frequency Selection (DFS) channels from your Automatic Channel Selection (ACS) list increases
performance. This selects channels from a list of available channels for a particular frequency band. The following example
is specific to US. Issue this command from the (config-wireless) context.
auto-select-channels 11a 36,38,40,42,44,46,48,149,153,157,161,165
E.5 Operate a 11bgn radio in the 20MHz band
Operate a 11bgn radio in the 20MHz band. Motorola Solutions recommends a 802.11bgn radio be operated in 20 MHz band
for optimal performance. An 802.11an radio can operate optimally in 20 MHz as well as 40 MHz bands.
While configuring channel power settings for indoor APs, do not configure the upper channel band. From the (config-
wireless) context, issue this command:
radio <RADIO-INDEX> channel-power indoor <CHANNEL-NUMBER> <CHANNEL-POWER>
For example,
RFS6000(config-wireless)#radio 1 channel-power indoor 1 20
use lowest basic rate. Provides maximum range
use highest basic rate. Provides maximum throughput (default)
