5.4 WAP Configuration
Sierra leverages an Aruba enterprise class wireless access point that runs Aruba’s Instant virtual
controller software. The WAP can be configured through the Aruba web GUI, or through the
console/sssh command line interface (CLI). The settings can be saved out to, and loaded from, a
configuration file.
The following example copies a configuration file to the tftp server:
sierra# copy config tftp 192.168.1.1 filename.cfg
The following example copies a configuration file to the WAP:
sierra# copy tftp 192.168.1.1 filename.cfg system config
reload
(this command restarts the WAP)
To maximize video streaming performance, the following settings have been included in the default
configuration file: /var/lib/tftpboot/SierraBlackLabel.cfg
•
Wide channel bands are enabled, but channel width has been limited to 40MHz. This helps
clients get on and off the air more quickly.
•
Minimum transmit rates have been set to 12 Mbps. This prevents weaker clients from
slowing down the network.
•
Arp Broadcast filtering is enabled. This converts arp broadcasts to unicast.
•
ARM Band Steering Mode is set to Balance Bands. This helps utilize both radios.
•
The min/max power settings of the 5 GHz radio have been set 6dbm higher than the 2.4
GHz radio. This accounts for the additional free space path loss and smaller receiver
aperture associated with the higher frequencies.
