APSD Mode Select Enable to enable Automatic Power Save Delivery (APSD), which is a power
management method. APSD is recommended if VoIP phones access the network
through the AP.
Bonjour Across VLan Bonjour enables end users to discover Services on their local network. While Bonjour
is focused on smaller networks (e.g. Home Networks) with the advent of mobile
customers wanting to discover services in close proximity, Bonjour becomes an ideal
option to facilitate that. However, as Bonjour utilizes mDNS which is constrained to
a single VLAN, customers are not able to discover services across multiple VLANs by
default. This setting enables Bonjour to support service across different VLANs. This
feature is disabled by default.
Frag Threshold The fragmentation threshold limits the size of packets transmitted over the network.
Acceptable values are even numbers from 256-2345. Packets that are under the
configured size are not fragmented. A value of 2346 means that packets are not
fragmented.
Short Retries The value in this field indicates the maximum number of transmission attempts on
frame sizes less than or equal to the RTS Threshold. The range is 1-255.
Long Retries The value in this field indicates the maximum number of transmission attempts on
frame sizes greater than the RTS Threshold. The range is 1-255.
Transmit Lifetime Shows the number of milliseconds to wait before terminating attempts to transmit
the MSDU after the initial transmission.
Receive Lifetime Shows the number of milliseconds to wait before terminating attempts to
reassemble the MMPDU or MSDU after the initial reception of a fragmented
MMPDU or MSDU.
Station Isolation When this option is selected, the AP blocks communication between wireless clients.
It still allows data traffic between its wireless clients and wired devices on the
network, but not among wireless clients. This feature is disabled by default.
• To enable Multicast and Broadcast Rate Limiting, click Enabled.
• To disable Multicast and Broadcast Rate Disabled, click Disabled.
Primary Channel This setting is editable only when a channel is selected and the channel bandwidth is
set to 40 MHz. A 40-MHz channel can be considered to consist of two 20-MHz
channels that are contiguous in the frequency domain. These two 20-MHz channels
are often referred to as the Primary and Secondary channels. The Primary Channel is
used for 802.11n clients that support only a 20-MHz channel bandwidth and for
legacy clients.
Use this setting to set the Primary Channel as the upper or lower 20-MHz channel in
the 40-MHz band.
Short Guard Interval The guard interval is the dead time, in nanoseconds, between OFDM symbols. The
guard interval prevents Inter-Symbol and Inter-Carrier Interference (ISI, ICI). The
802.11n mode allows for a reduction in this guard interval from the a and g definition
of 800 nanoseconds to 400 nanoseconds. Reducing the guard interval can yield a 10%
improvement in data throughput.
Select one of the following options:
• Enable — The AP transmits data using a 400 ns guard Interval when
communicating with clients that also support the 400 ns guard interval.
• Disable — The AP transmits data using an 800 ns guard interval.
