On enabling the Share Radar Hits setting, the Access Point (AP) shares radar select data with RF neighbor APs. The data is shared only with the RF neighbor AP and not with all APs.
By default, the setting is enabled. If you are experiencing false radar hits, you can disable this setting, and the impact will be limited to the affected AP. On disabling this setting, radar hit data will not be shared with RF neighbor APs.

The 802.11be standards build on 802.11ax by providing ultra-high throughput, improved resource utilization, and interference mitigation. The 320 MHz support increases the throughput and performance in the 6GHz band. The improved resource utilization is attributed to the introduction of Multiple Resource Units (MRU) in Orthogonal Frequency Division Multiple Access (OFDMA) transmission and Multi-Link Operation (MLO).

802.1X dynamic interface configuration allows for dynamic interface configuration on the 802.1X authenticator based on device profiling performed by a Network Access Controller (NAC). Traditionally, 802.1X authenticators require static interface configuration. This enhancement extends dynamic capabilities beyond existing features like dynamic VLAN assignment and ACL programming, enabling any type of interface configuration to be applied dynamically via the CLI.

This feature allows a user to adjust the MTU of radius requests for 802.1x supplicants. Currently this feature only adjusts the MTU size of radius requests for supplicants undergoing EAP TLS authentication. This can be useful in scenarios where hops between the switch and RADIUS doesn’t support IP MTU discovery and the switch ends up sending Access Requests based on the interface MTU size which get dropped at such hops. With this feature, a user has the flexibility to experiment and choose a MTU setting that works for such a topology forcing the Dot1x agent to send the Access Requests with the configured MTU.

This document specifically talks about support for supplicants doing EAP Password ( EAP-PWD ) based authentication. Defined in RFC5931, EAP-PWD is an EAP method that uses a shared password for authentication. Furthermore, this feature allows EOS devices to interoperate with systems that rely on EAP-PWD for deriving MACsec CAK/CKN from the EAP Master Session Key (MSK) and EAP Session ID as per 802.1X-2020.

You can now enable CloudVision to combine the authentication and authorization requests that it sends to a RADIUS server into a single request. When RADIUS is configured as the AAA provider, CloudVision will send separate authentication and authorization requests by default. This can cause issues with One-Time Password (OTP) users, as issued passwords are only valid for one request. Note: Non-OTP RADIUS systems will be unaffected by the change. To combine authentication and authorization requests, navigate to Settings > Access Control and enable the Combine Login Auth Requests checkbox.

Editing the profile will then affect all interfaces that the profile has been assigned to. You can also configure individual interfaces.

This feature adds the support for a standby server to the existing syslog logging mechanism for UDP syslog servers. The user can specify a logging group and specify remote syslog servers. The first host configured will be the “active” server, which means syslogs will be forwarded to that host whenever it is reachable via ICMP. The second host will be the “standby” server, which will receive syslogs if the active server goes down. This provides more robustness for setups with multiple potential syslog servers.
