show ap arm split-scan-history

show ap arm split-scan-history {ap-name <ap-name>|bssid <bssid>|ip-addr <ip-addr>}

Description

Show scanning information for a "split-scan", where 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. performs an additional scans on each channel within a 40 MHzMegahertz channel pair or 80 MHzMegahertz channel set.

Syntax

Parameter

Description

ap-name <ap-name>

Show scan data for an AP with a specific name.

bssid <bssid>

Show scan data for a specific Basic Service Set Identifier (BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly.) on an AP. An AP’s BSSIDBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly. is usually the AP’s MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. address.

ip-addr <ip-addr>

Show scan data for an AP with a specific IP address. Enter the IP address in dotted-decimal format.

Usage Guidelines

If 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. reports a high noise floor on a channel within a 40 MHzMegahertz channel pair or 80 MHzMegahertz channel set, 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. performs an additional 20 MHzMegahertz scan on each channel within that channel pair or set, to determine the actual noise floor of each affected channel. This allows 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. to avoid assigning the overutilized channel, while still allowing channel assignments to the other unaffected channels in that channel pair or set.
