Multi BandBand refers to a specified range of frequencies of electromagnetic radiation. Scan

If enabled, single-radio APs will try to scan across bandsBand refers to a specified range of frequencies of electromagnetic radiation. for rogue AP detection.

Rogue AP Aware

If enabled, Aruba APs may change channels to contain off-channel rogue APs with active clients. This security features allows APs to change channels even if the Client Aware setting is disabled.

This setting is disabled by default, and should only be enabled in high-security environments where security requirements are allowed to consume higher levels of network resources. You may prefer to receive Rogue AP alerts via SNMPSimple Network Management Protocol. SNMP is a TCP/IP standard protocol for managing devices on IP networks. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention.  traps or syslog events.

Scan Interval

If Scanning is enabled, the Scan Interval defines how often the AP will leave its current channel to scan other channels in the bandBand refers to a specified range of frequencies of electromagnetic radiation..

Off-channel scanning can impact client performance. Typically, the shorter the scan interval, the higher the impact on performance. If you are deploying a large number of new APs on the network, you may want to lower the Scan Interval to help those APs find their optimal settings more quickly. Raise the Scan Interval back to its default setting after the APs are functioning as desired.

Aggressive Scanning

When the aggressive scanning feature is enabled, an AP radio with no clients will scan channels every second.

Active Scan

If enabled, the AP initiates active scanning via probe request. This option elicits more information from nearby APs, but also creates additional management traffic on the network. Active Scan is disabled by default, and should not be enabled except under the direct supervision of Aruba Support.

Scanning

Shows if the AP has enabled or disabled AP scanning of other channels.

This helps avoid higher levels of interference on the WLANWireless Local Area Network. WLAN is a 802.11 standards-based LAN that the users access through a wireless connection.. Although this setting is disabled by default, you may want to enable this feature if your APs are deployed in close proximity (e.g. less than 60 feet apart).

Scan Mode

This parameter defines the scan mode for the AP.

all-reg-domain: The AP scans channels within all regulatory domains. This is the default setting.

reg-domain:Limit the AP scans to just the regulatory domain for that AP.

Client Match

The client match 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 enabled by default

Client Match report

interval (sec)

This interval defines how often an AP sends an updated client probe report to the controller. Each client probe report contains a list of MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network.  addresses for clients that have been active in the last two minutes, and the AP radio SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. values seen by those clients.

Client Match Unsteerable Client Ageout Interval

The client entries in an unsteerable client list remain in effect for the interval defined by this parameter before they age out.

Client Match Unsteerable Client Ageout

When client match and the client match unsteerable client ageout feature are enabled, the controller periodically sends APs that are not a desired AP match for a client in a list of unsteerable clients. These lists contain a list of MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. addresses for up to 128 clients that should not be steered to that AP.

Client Match Sticky Client

If the SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. value drops below the threshold defined by the cm-sticky-snr parameter for three consecutive check intervals, that client may be moved to an different AP.

Client Match Sticky Client

Check SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. (dBDecibel. Unit of measure for sound or noise and is the difference or ratio between two signal levels.)

If the client's received signal strength indicator (RSSIReceived Signal Strength Indicator. RSSI is a mechanism by which RF energy is measured by the circuitry on a wireless NIC (0-255). The RSSI is not standard across vendors. Each vendor determines its own RSSI scale/values.) is above this signal-to-noise ratio (SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise.) threshold, that client will be allowed to stay associated to its current AP. If the client's received signal strength is below this threshold, it may be moved to a different AP.

Client Match SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise.

threshold(dBDecibel. Unit of measure for sound or noise and is the difference or ratio between two signal levels.)

A client triggered to move to a different AP may consider an AP radio a better match if the client detects that the signal from the AP radio is stronger than its current radio by the dBDecibel. Unit of measure for sound or noise and is the difference or ratio between two signal levels. level defined by the cm-sticky-snr-thresh parameter, and the candidate radio also has a minimum signal level defined by the cm-sticky-min-signal parameter.

Client Match Sticky

Min Signal

A client triggered to move to a different AP may consider an AP radio a better match if the client detects that the signal from the candidate AP radio is at or higher than the minimum signal level defined by this parameterand the candidate radio has a higher signal strength than the radio to which the client is currently associated. (The required improvement in signal strength can be defined using the cm-sticky-snr-delta command.)

Client Match Restriction timeout (sec)

When a client is steered from one AP to a more desirable AP, the steer timeout feature helps facilitate the move by defining the amount of time that any APs to which the client should NOT associate will not respond to the AP.

Client Match Load Balancing threshold (%)

When the client match feature is enabled, clients may be steered from a highly utilized channel on an AP to a channel with fewer clients. If a channel on an AP radio has this percentage fewer clients than another channel supported by the client, the client match feature may move clients from the busier channel to the channel with fewer clients.

SNR is used for comparing the level of a desired signal with the level of background noise. values for up to 16 candidate APs per client. This table is periodically updated as APs send client probe reports to the controller. This parameter defines the amount of time that the controller should retain client match data from each client probe report.

Client Match Max Steer Failures

The controller keeps track of the number of times the client match feature failed to steer a client to a different radio, and the reason that each steer attempt was triggered. If the client match feature attempts to steer a client to a new radio multiple consecutive times for the same reason but client steering fails each time, the controller notifies the AP to mark the client as unsteerable for that specific trigger.

This parameter defines the maximum allowed number of client match steering fails with the same trigger before the client is marked as unsteerable for that trigger.

Client Match Load Balancing Client Threshold

If an AP radio has fewer clients than the client match load balancing threshold defined by this parameter, the AP will not participate in load balancing.

Client Match Load Balancing SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. Threshold (dBDecibel. Unit of measure for sound or noise and is the difference or ratio between two signal levels.)

Clients must detect a SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. from an underutilized AP radio at or above this threshold before the client match feature considers load balancing a client to that radio.
