Software release 6.4.2 is available for Enterprise Wi-Fi. 6.4.2 software release contains features, enhancements and bug fixes. Following are the downloads available for software release 6.4.2:
New Features
Auto-RF
With the Auto-RF feature, AP collects a number of RF-statistics and uses that information to give a better Radio Frequency (RF) environment to wireless clients, by selecting the right channel and Tx power for each radio. This results in a better end-user experience in terms of application performance and call quality.
Auto-RF consists of two functionalities:
- Dynamic channel: Helps radios to always select a better channel at boot time and post boot if channel conditions change later.
- Auto power: Helps radios to come up with the right Tx power to handle coverage holes and minimize RF interference.
Device class filter
This feature applies wireless policies to the client-based device class (notebook, phone, tablet, and laptop) and its type (Windows, Mac, and Android).
Flooding attacks in Wireless Intrusion Detection Systems (WIDS)
The WIDS feature is used to detect different types of flood attacks. A flood attack occurs when a rogue client sends a huge number of packets of a specific type to the AP to disrupt the normal working of the AP. This feature can detect the following types of flood attacks:
- Association
- Authentication
- Disassociation
- De-authentication
- Extensible Authentication Protocol over LAN (EAPoL)
Opportunistic Wireless Encryption (OWE)
OWE is a Wi-Fi standard, which ensures that the communication between each pair of endpoints is protected from other endpoints. The OWE transition mode allows OWE-capable STAs to access the network in OWE authentication mode.
Enhancements
Scale Limit: 2K ePSK
From System Release 6.4.2 onwards, Enterprise Wi-Fi 6 XV series Access Points support 2K ePSK entries per WLAN. Other Access Points (e410, e430, e510, e600, and e700) continue to support 1024 ePSK entries per WLAN.
