With the 13.0.1 release, you can authenticate wired hosts connected to the LAN ports of access points (W-118 and W-318) using 802.1X or MAC-based authentication. You can configure the authentication parameters for each downlink port on the access point (AP) using a LAN Port profile in CV-CUE. The communication happens either through a bridged network or transferred using L2 Tunnels.

The Federal Communications Commission (FCC) mandates that operations in the 6 GHz band require all Access Points (APs) operating at standard power to communicate their geolocation to an Automated Frequency Coordination (AFC) system. The AFC system evaluates this geolocation data to ensure compliance with regulatory requirements by providing the APs with the permissible frequencies and the maximum allowable transmission power for each frequency range at their specific locations.

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.

BGP inbound update processing delay is a feature in EOS where an optional delay is applied prior to processing inbound UPDATE messages from a peer(s). The duration of the delay is configurable per peer. The delay is applied to UPDATE messages for all the address families that are negotiated with the peer. The delay timer starts when the peer becomes established. The routes from such peers are processed only after the timer expires. Any routes received after the timer expired are processed as usual without the delay. Both the default VRF and non-default VRFs are supported.

BGP Monitoring Protocol (BMP) allows a monitoring station to connect to a router and collect all of the BGP announcements received from the router’s BGP peers. The announcements are sent to the station in the form of BMP Route Monitoring messages generated from path information in the router’s BGP internal tables. A BMP speaker may choose to send either Adj-Rib-In routes, or Loc-Rib routes (as defined by RFC9069 ), or both.

Without the support mentioned in this TOI, when a BGP route has two or more levels of recursion, the BGP process does not utilize the IGP distance in the route selection process.

When a Provider Edge (PE) device loses BGP connectivity to the core (uplink) devices, it may be unable to forward any traffic from its downlink devices, typically CE (Customer Edge) devices. It is beneficial to indicate this connectivity loss to these CE devices so that they may find alternative paths to forward traffic.
