Dual Tag VLAN mapping feature defines mapping between (outer VID and inner VID of double tagged packet) and bridging

The eBgp "ip next hop unchanged" feature allows a router to send routes to its eBgp peers without changing their next

ECMP Hash visibility CLI determines the output interface for an ECMP set based on the flow parameters supplied by the user. Ingress interface, source IP address, destination IP address and IP protocol are the required parameters. L4 source and destination ports and VLAN identifier are optional, but should be specified if the packet has them.

The EOS Event Manager feature provides the ability to specify a condition and an action to be carried out when that

The EOS Event Manager feature, introduced in 4.17.0F,  provides the ability to specify a condition and an action

The EOS Event Manager feature provides the ability to specify a condition and an action to be carried out when that

Users can now define a global LAG hashing profile. The global LAG hashing profile will be applied to all linecards

The feature enables support for displaying per traffic class counters on ingress interfaces. The feature is

This feature enables dataplane forwarding of IPv4 traffic on interfaces that are not IPv4 address enabled, but only

With this, IPv6 routes can be configured pointing to a static Nexthop group of 2 types:. Type

IS IS adjacency uptime describes the uptime or downtime of neighbors since the last state change.

This feature enables an Arista switch to run the IS IS routing protocol over a tunnel interface to another IS IS

Segment Routing provides mechanism to define end-to-end paths within a topology by encoding paths as sequences of sub-paths or instructions. These sub-paths or instructions are referred to as “segments”. IS-IS Segment Routing (henceforth referred to as IS-IS SR) provides means to advertise such segments through IS-IS protocol.

L3 interface ingress counters can be used to count routable traffic coming into the box on sub interfaces and vlan

LACP State Transition Event Monitoring on Arista switches allows for quick and filterable viewing of LACP state

E-Tree is an L2 EVPN service (defined in RFC8317) in which each attachment circuit (AC) is assigned the role of Root or Leaf. Root ACs can communicate with leaf ACs and other root ACs. Leaf ACs can only communicate with root ACs. Leaf AC to leaf AC traffic is blocked. In this implementation, ACs are configured at the VLAN level, and the forwarding rules are enforced using a combination of local configuration of leaf VLANs (for local hosts), and asymmetric route targets (for remote hosts).

Support for Media Access Control Security (MACsec) with static keys was added in EOS 4.15.4. This feature brings

MapReduce Tracer is an existing feature that monitors MapReduce nodes that are directly connected to Arista

In an MLAG setup, periodic TCP/UDP heartbeats are sent over peer link to ensure IP connectivity between peers. Prior

MPLS-over-GRE encapsulation support in EOS 4.17.0 enables tunneling IPv4 packets over MPLS over GRE tunnels. This feature leverages next-hop group support in EOS. With this feature, IPv4 routes may be resolved via MPLS-over-GRE next-hop group to be able to push one MPLS label and then GRE encapsulate the resulting labelled IPv4 packet before sending out of the egress interface.

LANZ adds support for monitoring congestion on backplane (or fabric) ports on DCS 7304, DCS 7308, DCS 7316, DCS

NAT peer state synchronization feature provides redundancy and resiliency for dynamic NAT across a pair of devices in an attempt to mitigate the risk of single NAT device failure. The main motivation is that since the NAT state is shared between two switches, the failure of one switch can be tolerated since the other switch will retain the translations.

Nexthop group match in PBR policy enables the user to match incoming packets being routed to a specified nexthop group

EOS 4.17.0F adds support for BFD in OSPFv3. BFD provides a faster convergence in scaled deployments where using

The per port per VLAN feature allows application of QoS policies for IP, IPv6 and non IP traffic on a per port per VLAN

Per VLAN MAC Learning is a feature to enable/disable mac learning per-vlan instead of per-port. Using this feature with VxLAN could provide a poor-man version of Point-to-Point VxLAN Pseudowire services.

Ingress policing on front panel ports is supported on DCS 7010X and DCS 7050X since EOS4.14.0F. When ingress policing
