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.

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.

spectrum-load-balancing

The Spectrum Load Balancing feature helps optimize network resources by balancing clients across channels, regardless of whether the AP or the controller is responding to the wireless clients' probe requests.

If enabled, the controller compares whether or not an AP has more clients than its neighboring APs on other channels. If an AP’s client load is at or over a predetermined threshold as compared to its immediate neighbors, or if a neighboring Aruba AP on another channel does not have any clients, load balancing will be enabled on that AP. This feature is disabled by default.

Usage Guidelines

This command configures radios that operate in the 2.4 GHzGigahertz. frequency bandBand refers to a specified range of frequencies of electromagnetic radiation., which includes radios utilizing the IEEEInstitute of Electrical and Electronics Engineers. 802.11b802.11b is a WLAN standard often called Wi-Fi and is backward compatible with 802.11. Instead of the Phase-Shift Keying (PSK) modulation method used in 802.11 standards, 802.11b uses Complementary Code Keying (CCK) that allows higher data speeds and makes it less susceptible to multipath-propagation interference. 802.11b operates in the 2.4 GHz band and the maximum data transfer rate is 11 Mbps./g 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.
