General

Client Match

The ClientMatch feature helps optimize network resources by balancing clients across channels, regardless of whether the AP or the managed device is responding to the wireless clients' probe requests.

If enabled, the managed device compares whether 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. For details, see ClientMatch Overview .

Enabled

Advanced

Rogue AP Aware

If you have enabled both the Scanning and Rogue AP options, 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 SNMP Simple 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.

Disabled

Active Scan

When you enable Active Scan, an 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.
