Section 4 - Managing the Access Point
Field Description
RTS Threshold Specify a Request to Send (RTS) Threshold value between 0 and 2347.
The RTS threshold indicates the number of octets in an MPDU, below which an RTS/CTS
handshake is not performed.
Changing the RTS threshold can help control trafc ow through the AP, especially one
with a lot of clients. If you specify a low threshold value, RTS packets will be sent more
frequently. This will consume more bandwidth and reduce the throughput of the packet.
On the other hand, sending more RTS packets can help the network recover from
interference or collisions which might occur on a busy network, or on a network experiencing
electromagnetic interference.
Maximum Stations Specify the maximum number of stations allowed to access this AP at any one time.
You can enter a value between 0 and 200.
Transmit Power Enter a percentage value for the transmit power level for this AP.
The default value, which is 100%, can be more cost-efcient than a lower percentage since
it gives the AP a maximum broadcast range and reduces the number of APs needed.
To increase capacity of the network, place APs closer together and reduce the value of the
transmit power. This helps reduce overlap and interference among APs. A lower transmit
power setting can also keep your network more secure because weaker wireless signals are
less likely to propagate outside of the physical location of your network.
Fixed Multicast Rate Select the multicast trafc transmission rate you want the AP to support.
Legacy Rate Sets Check the transmission rate sets you want the AP to support and the basic rate sets you
want the AP to advertise:
•) Rates are expressed in megabits per second.
•) Supported Rate Sets indicate rates that the AP supports. You can check multiple rates
(click a check box to select or de-select a rate). The AP will automatically choose the
most efcient rate based on factors like error rates and distance of client stations from
the AP.
•) Basic Rate Sets indicate rates that the AP will advertise to the network for the
purposes of setting up communication with other APs and client stations on the
network. It is generally more efcient to have an AP broadcast a subset of its
supported rate sets.
MCS (Data Rate)
Settings (802.11n
modes only)
This eld shows the Modulation and Coding Scheme (MCS) index values supported by the
radio. Each index can be enabled and disabled independently.
Broadcast/Multicast
Rate Limiting
Enabling multicast and broadcast rate limiting can improve overall network performance by
limiting the number of packets transmitted across the network.
By default the Multicast/Broadcast Rate Limiting option is disabled. Until you enable
Multicast/Broadcast Rate Limiting, the following elds will be disabled:
•) Rate Limit - Enter the rate limit you want to set for multicast and broadcast trafc. The
limit should be greater than 1, but less than 50 packets per second. Any trafc that
falls below this rate limit will always conform and be transmitted to the appropriate
destination. The default and maximum rate limit setting is 50 packets per second.
•) Rate Limit Burst - Setting a rate limit burst determines how much trafc bursts can
be before all trafc exceeds the rate limit. This burst limit allows intermittent bursts of
trafc on a network above the set rate limit. The default and maximum rate limit burst
setting is 75 packets per second.
TSPEC Mode Regulates the overall TSPEC mode on the AP. The options are:
•) On — The AP handles TSPEC requests according to the TSPEC settings you
congure on the Radio page. Use this setting if the AP handles trafc from QoS-
capable devices, such as a Wi-Fi CERTIFIED phone.
•) Off — The AP ignores TSPEC requests from client stations. Use this setting if you do
not want to use TSPEC to give QoS-capable devices priority for time-sensitive trafc.
TSPEC Voice ACM
Mode
Regulates mandatory admission control (ACM) for the voice access category. The options
are:
•) On — A station is required to send a TSPEC request for bandwidth to the AP before
sending or receiving a voice trafc stream. The AP responds with the result of the
request, which includes the allotted medium time if the TSPEC was admitted.
•) Off — A station can send and receive voice priority trafc without requiring an admitted
TSPEC; the AP ignores voice TSPEC requests from client stations.

- On networks that use ieee 802 x port based network access control a supplicant client cannot gain access to the network until the 802 x authenticator grants access if your network uses 802 x you must configure 802 x authentication information that the ap can supply to the authenticator 19
