Data center switches and servers have traditionally been managed by separate teams using different tools creating complexity in setting up and maintaining the end to end network in the datacenter.
In an AI network, the nature of the workload amplifies the effect of a single server’s network failure or network misconfiguration impacting the work of large numbers of machines in the network. This is costly both in lost productivity and in the high level of support required to fix network errors that can occur in the compute and network domains.

This feature provides protocol independent UCMP support for all the routes which follow the IGP path provided there is no UCMP computation done at the protocol level itself. Enabling this feature allows for optimal bandwidth utilization over the links by considering link capacity for rationalizing weight among the nexthop members for all the routes which follow the IGP path.

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).

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.

802.1X supplicant feature supports different Extensible Authentication Protocol( EAP ) methods for 802.1X authentication. 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.
