For a pair of QSFP100 ports grouped together on a gearbox, it is possible to enable a 10G or 25G link on the first primary port while maintaining the usage of the secondary port at any speed. For two QSFP100 ports on a gearbox, the primary port allows for breakout speeds 4x10G and 4x25G, while the secondary does not. The configuration of the primary port determines whether the secondary port can be used since in a full breakout mode such as 4x10G the secondary port is forced inactive.

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).

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.

This studio enables you to quickly configure access interfaces towards endpoint devices in your campus network. This configuration relates to the devices in Access Pods deployed using the Campus Fabric (L2/L3/EVPN) Studio. The studio consists of port profiles and campus networks. You can create port profiles, which contain configuration for attributes like speed and MTU, which you can then assign to device interfaces in a campus fabric. Editing the profile will then affect all interfaces that the profile has been assigned to. You can also configure individual interfaces.

This document describes BFD RFC7130 mode on EOS. RFC7130 defines a mechanism to run BFD protocol over port channels with an independent asynchronous BFD session on every port channel member link. With RFC7130 support, the port channel member link will be removed from forwarding if the BFD session state transitions from UP to DOWN on the member link. This is useful for quickly detecting failures where L1 stays connected but the interface is unable to forward traffic.
