assoc-boost

The assoc-boost parameter increases the client association success rate, especially in a noisy environment. When this parameter is enabled:

The management frame retransmission retry limit in the radio firmware for both authentication and association response is increased, thereby increasing the management frame retransmission rate.

If the management frame retransmission retry limit is reached, after a short time delay another round of management frames are scheduled.

If a client starts an association (by sending a probe or authentication request), AP scanning is rejected for 5 seconds, thereby not missing the client association request.

The available channels depend on the regulatory domain (country). Channel number configuration options for 20 MHzMegahertz, 40 MHzMegahertz, and 80 Mhz modes:

num: Entering a channel number disables 40 MHzMegahertz mode and activates 20 MHzMegahertz mode for the entered channel.

num+: Entering a channel number with a plus (+) sign selects a primary and secondary channel for
40 MHzMegahertz and 80 Mhz modes. The number entered becomes the primary channel and the secondary channel is determined by increasing the primary channel number by 4. Example: 157+ represents 157 as the primary channel and 161 as the secondary channel.

num-: Entering a channel number with a minus (-) sign selects a primary and secondary channel for
40 MHzMegahertz and 80 Mhz modes. The number entered becomes the primary channel and the secondary channel is determined by decreasing the primary channel number by 4. Example: 157- represents 157 as the primary channel and 153 as the secondary channel.

Transmission power may be further limited by regulatory domain constraints and AP capabilities.

NOTE: Use this parameter to set transmit power levels for APs associated to a stand-alone controller not using ARMAdaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment. .

Usage Guidelines

This command configures radios that operate in the 5 GHzGigahertz. frequency bandBand refers to a specified range of frequencies of electromagnetic radiation., which includes radios utilizing the IEEEInstitute of Electrical and Electronics Engineers. 802.11a802.11a provides specifications for wireless systems. Networks using 802.11a operate at radio frequencies in the 5 GHz band. The specification uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) that is especially well suited to use in office settings. The maximum data transfer rate is 54 Mbps. or IEEEInstitute of Electrical and Electronics Engineers. 802.11n802.11n is a wireless networking standard to improve network throughput over the two previous standards, 802.11a and 802.11g. With 802.11n, there will be a significant increase in the maximum raw data rate from 54 Mbps to 600 Mbps with the use of four spatial streams at a channel width of 40 MHz. standard. Channels must be valid for the country configured in the AP regulatory domain profile (see ap regulatory-domain-profile).To view the supported channels, use the show ap allowed-channels command.

APs initially start up with default ack-timeout, cts-timeout and slot-time values. When you modify the maximum-distance parameter in an rf dot11a radio profile or rf dot11g radio profile, new ack-timeout, cts-timeout and slot-time values may be derived, but those values are never less then the default values for an indoor AP.

Mesh radios on outdoor APs have additional constraints, as mesh links may need to span long distances. For mesh radios on outdoor APs, the effect of the default maximum-distance parameter on the ack-timeout, cts-timeout and slot-time values depends on whether the APs are configured as mesh portals or mesh points. This is because mesh portals use a default maximum-distance value of 16,050 meters, and mesh points use, by default, the maximum possible maximum-distance value.

The maximum-distance value should be set correctly to span the largest link distance in the mesh network so that when a mesh point gets the configuration from the network it will apply the correct ack-timeout, cts-timeout and slot-time values.The values derived from the maximum-distance setting depend on the bandBand refers to a specified range of frequencies of electromagnetic radiation. and whether 20Mhz/40MHz mode of operation is in use.
