With the 13.0 release, CloudVision Cognitive Unified Edge (CV-CUE) lets you configure Unique PSK (UPSK) for client authentication. UPSKs allow users to connect to the same SSID using a unique PSK which is user specific. UPSK provides added security as compared to single PSK because single PSKs are easily compromised.

With the 16.0 release, you can authenticate edge devices from a centrally managed network access control server using the 802.1X authentication. As a network administrator, you want to authenticate the access points (APs), before the APs connect to the network. To enable the authentication, you need to first configure the uplink port on the AP using CV-CUE.

This feature adds the capability to import as path access-list from a URL, in release 4.20.1F. The file specified by the URL can contain one or more as-path access-list entries. All the entries that are in the file are added to the as-path access-list being configured. This feature gives the advantage of using one EOS CLI command to configure many as-path access-list entries, instead of adding each one of them line by line in the CLI.

EOS 4.15.0F added support for a CLI knob to determine whether the L3 forwarding agent (responsible for programming FECs and routes into hardware) would react to BFD status events for an interface to update next-hop programming for FECs programmed in hardware. This required two events, one for the BFD session to transition to an “Up” status and a subsequent transition to a “Down” status. This is identical to how various protocols in EOS (i.e. BGP, IS-IS) leverage BFD for faster down detection, and is useful to allow the L3 forwarding agent to preemptively remove next hops that would later be deprogrammed due to protocol session status state.

Virtual Private LAN Service (VPLS) can be used when one wishes to connect several LANs dispersed across a packet switched network. VPLS can allow the dispersed LANs to act like a single bridged LAN by providing a service to connect the LANs. The service will appear like an Ethernet LAN (in almost all regards). VPLS achieves this by creating a mesh of pseudowires that connect the dispersed LANs, while also processing the traffic that moves through the pseudowires in a similar way to how a L2 service would. For example, MAC address learning, flooding and forwarding functions are applied to the pseudowire traffic in a VPLS. This allows VPLS to mimic the functionality of an any-to-any L2 service when connecting dispersed LANs.

This feature is available in the VLAN configuration mode. When a switch receives a packet with unknown destination MAC address on a VLAN, L2 miss happens. The current behavior for L2 miss packets is to flood the packet on all ports of the VLAN. In certain cases, there may be a preference to drop or log L2 miss packets instead of flooding them across the VLAN.

This feature allows an operator to configure a centralized routing topology with an IPv6 VXLAN underlay. This is useful for customers who want to use an anycast (VARP) gateway for routing over an IPv6 control plane. VARP allows multiple switches to simultaneously route packets from a common IP address in an active-active router configuration. Each switch is configured with the virtual IP address and a common virtual MAC address.
