This feature introduces the support for IPv4 ACL configuration under GRE and IPsec tunnel interfaces and IPv6 ACL configuration under GRE tunnel interfaces. The configured ACL rules are applied to a tunnel terminated GRE packet i.e. any IPv4/v6-over-GRE-over-IPv4 that is decapsulated by the GRE tunnel-interface on which the ACL is applied, or a packet terminated on IPsec tunnel i.e, IPv4-over-ESP-over-encrypted-IPv4 packet that is decapsulated and decrypted by the IPsec tunnel interface on which the ACL is applied.

By default,  inner IP header of a GRE packet is used for LAG hashing. With this feature, LAGs can hash GRE traffic

Hardware Table Capacity Monitoring is a new feature to keep track of the capacity and utilization of various hardware forwarding resources and generate alerts/syslogs when the utilization exceeds a threshold value. Users can keep track of the current usage statistics using a single show command, and also configure thresholds on a per-resource basis, to be notified about any high-utilization upfront, before reaching any resource limits. The Main use-case would be for troubleshooting in overflow situations and avoid overflows altogether by taking corrective actions on high utilization.

EOS-4.20.5 adds support for hardware-accelerated sFlow on compatible R2 platforms.

This feature allows capturing packets and byte counts at high resolution on physical interfaces, down to 1 ms granularity. Allows for detecting anomalous packet flows, or confirming the expected bandwidth usage. Requires selecting a set of interfaces to sample, a time resolution, and sampling duration.

Keeping Wi Fi Access Point (AP) firmware up to date allows network administrators to take advantage of the latest

This feature introduces support for scaling both IPv4 and IPv6 hosts on our devices. Existing MDB profiles offer a maximum host scale of 128k with unique MAC rewrites. However, if hosts share the MAC rewrites, the scale can reach up to 204k. To address this issue, we are introducing a new MDB profile that will support a host scale of up to 192k when each host has a unique MAC rewrite. If hosts share the MAC rewrites, the scale can reach up to 256k.

Hotspot 2.0 is a standard for public-access Wi-Fi that enables seamless roaming among Wi-Fi networks and between Wi-Fi and cellular networks. With Hotspot 2.0, Passpoint-certified mobile devices such as laptops and smartphones can automatically discover and connect to Wi-Fi networks without the need of signing in manually. It is based on IEEE 802.11u standard for Interworking with External Networks. 

With the 15.0 release, CloudVision Cognitive Unified Edge(CV-CUE) provides you the ability to list down Vulnerable SSIDs and Hotspot SSIDs. CV-CUE takes action on the listed SSIDs according to the applied WIPS policy. 

External controllers can communicate with HSC (Hardware Switch Controller) running on CVX/EOS using the OVSDB

This is an extension to BGP EVPN VPNs that allow us to use iBGP as the PE-CE protocol. This feature also provides a way to isolate the customer’s network BGP attributes from the SP backbone’s attributes, by saving them into a special attribute called ATTR_SET, code 128. This separation introduces a “route server” model that allows the customer’s BGP path attributes to be stored in the SP backbone along with the VPN-IPv4/v6 paths.

ICMP Probe allows querying of interface status and ARP or Neighbor Discovery table status remotely.  It is a request/response protocol, similar to ping, but instead of simply responding to the request, it responds with information about a local interface or a remote neighbor.  The node being queried is called the "proxy node"

IGMP Snooping Proxy feature is an optimization over IGMP snooping. When IGMP Snooping Proxy is enabled, the switch

This feature enables the user to configure a list or range of BGP attributes to be ignored by the router on receipt of a BGP update message. The BGP attributes are discarded from the BGP update message, and unless the action of discarding an attribute causes the update message to trigger error handling, then the update message is parsed as normal.

You can import Ekahau floor plans to CloudVision Cognitive Unified Edge (CV-CUE) and then manage the access points (AP) from CV-CUE. Once you import the floor plan to CV-CUE, you can map the AP to CV-CUE and start managing the AP.

Each ARP/ND packet into a switch may generate an update for the switch ARP/Neighbor table and this update may need to be synchronized with the MLAG peer when VXLAN is configured. Prior to this feature, these updates (on a VXLAN setup) are synchronized by sending an UDP packet (one packet per update) containing the IP/MAC/VLAN information from the MLAG peer where the ARP/ND packet is received to the other MLAG peer. 

For network monitoring and troubleshooting flow related issues, it is desirable to know the path, latency, queue and congestion information for flows at different times. The inband telemetry feature(INT), based on Inband Flow Analyzer RFC draft -IFA 2.0 and IFA 1.0(on some platforms) , is used to gather per flow telemetry information like path, per hop latency and congestion. INT is supported for both IPv4 and IPv6 traffic.

The Interface Diagnostics quick action provides you with a fast and efficient way to run interface cycles and cable diagnostics on your campus devices from the Campus Health Overview Dashboard. The devices available are those with a Campus tag, which is automatically assigned to devices configured with the Campus Fabric Studio (L2/L3/EVPN).

You can use the Access Interface Configuration quick action to assign configuration profiles to devices. The guided workflow will display an illustration of device front panels, which you can use to select interfaces from.

One of the reasons why Wi-Fi clients encounter RF issues is non-Wi-Fi interference. All Wi-Fi 6 and above APs can perform interference classification. CloudVision Cognitive Unified Edge (CV-CUE) classifies interference into four categories — Wi-Fi, Microwave Oven (MWO), Frequency Hopping Spread Spectrum (FHSS), and Continuous Wave (CW).

The internet exit feature enables hosts attached to a VRF in an edge router to reach prefixes that may be reachable over the internet. Since the addresses assigned within a VRF may be non-routable private addresses which cannot be directly used when going to the Internet, the NAT feature is used as a part of the Internet exit solution to provide internet connectivity.

IPv6 multicast routing protocols are used to distribute IPv6 datagrams to one or more recipients. IPv6 PIM builds and maintains multicast routing using reverse path forwarding (RPF) based on the unicast routing table. IPv6 PIM is protocol-independent and can use routing tables consisting of OSPFv3, IPv6 BGP or static routes, for RPF lookup. MLD is used to discover multicast hosts and maintain group membership on a directly attached link.

With this feature, Arista 7050 and 7050X series of switches can now decapsulate IP in IP tunneled packets. When IP in IP decapsulation is configured, incoming packets with an outer IP header having IpProto=4 (IP in IP) and IpDest matching the one configured will be decapsulated, meaning that the outer IP header will be removed from the packet and all subsequent forwarding decisions will be based on the inner IP header.

With this feature, IP packets matching a static Nexthop Group route can be encapsulated within an IP in IP tunnel and

When the next hop of an IP route (hereafter referred to as the dependent route) resolves over another IP route (hereafter referred to as the resolving route), the adjacency information of the resolving route’s FEC is typically duplicated into the dependent route’s FEC. With this feature, we prevent the duplication of the adjacency information. Instead, the dependent route’s FEC points to the resolving route’s FEC, forming a hierarchical FEC for the dependent route.

Support for IPSec connections in a full-cone Network/Port Address Translation (NAT) environment has been added to the Dynamic Path Selection (DPS) setup. DPS optimizes application performance by selecting different paths for various types of traffic. In this configuration, STUN is used to discover the translated IP address of WAN interfaces and export it to BGP.
