Client Match
Client Match is an Aruba Central service which helps to improve the experience of wireless clients. Client match identifies wireless clients that are not getting the required level of service at the AP to which they are currently associated and intelligently steers them to an AP radio that can provide better service and thereby improves user experience.
Steer Types
Client match periodically checks the health of current association of the clients and determines if a sticky steer or bandBand refers to a specified range of frequencies of electromagnetic radiation. steer should be considered.
Sticky Steer
Sticky clients tend to stay associated to an AP despite deteriorating signal levels. Client match continuously monitors the 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. of sticky clients while they are associated to an AP, and if needed, move them to a radio that would offer better experience. This prevents clients from remaining associated to an AP with less than ideal RSSI, which can cause poor connectivity and reduce performance for other clients associated with that AP.
Band Steer
Dual-band clients can associate with a 2.4 GHzGigahertz. radio or 5 GHz radio. In band steer, client match moves dual-band clients from the 2.4 GHz radio to the 5 GHz radio of the same AP.
Steering Methods
After determining the steer type, client match determines the best neighbor radio to steer the client to and orchestrates the client steer by sending action messages to the APs to carry out the steer. The way client match steers the clients depends on whether the clients are 802.11v802.11v is an IEEE standard that allows client devices to exchange information about the network topology and RF environment. This information is used for assigning best available radio resources for the client devices to provide seamless connectivity.-capable.
Steering for 802.11v-capable Client
To steer 802.11v-capable clients, client match triggers the AP to send out an 802.11v BSSBasic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. transition management request to the client and waits for a response.
Steering for Non-802.11v-capable Client
To steer non-802.11v-capable clients, client match triggers all neighboring AP radios (except the intended destination) to block the client from associating for 5 seconds. 2 seconds after that, the AP to which the client is currently associated sends an 802.11802.11 is an evolving family of specifications for wireless LANs developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). 802.11 standards use the Ethernet protocol and Carrier Sense Multiple Access with collision avoidance (CSMA/CA) for path sharing. deauthentication management frame to the client. When the client tries to re-associate, only the intended AP radio allows the client to associate with it.
