Multiprotocol Label Switching (MPLS) is a networking process that replaces complete network addresses with short

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.

This feature allows the Arista switch to act as the tunnel head for an MPLS tunnel and is exposed through two

While migrating from PVST to MSTP, or vice verse, the network engineer may choose not to run MSTP throughout the

Multi hop BFD  allows for liveness detection between systems whose path may consist of multiple hops. With an

This feature adds the support for OSPFv3 multi-site domains (currently this feature is added for IPv6 address family only) described in RFC6565 (OSPFv3 as a Provider to Customer Edge Protocol for BGP/MPLS IP Virtual Private Networks (VPNs) ) and enables routes BGP VPN routes to retain their original route type if they are in the same OSPFv3 domain. Two sites are considered to be in the same OSPFv3 domain if it is intended that routes from one site to the other be considered intra-network routes.

Multicast Only Fast Reroute (MoFRR) is a feature based on PIM sparse mode (PIM SM) protocol to minimize packet loss in a

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

In Tap Aggregation mode, an interface can be configured as tap or tool port. Tap ports are used to 'tap' the traffic and

Multiple VLAN Registration Protocol (MVRP) is a Layer 2 protocol. The protocol allows access points to propagate the VLAN created on CV-CUE to the connected Switches. The real-time propagation of configuration allows you the flexibility of configuring your wired and wireless network in one interface and distributing it to other active interfaces. You do not have to worry about managing and maintaining the configurations in all interfaces.

The NAT Application Gateway (ALG) feature allows FTP connections between client server to be translated using

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. Each switch advertises connection state updates to its peer.  State update consists of connection creation, connection state change (TCP mostly) or connection tear down

In the 13.0 release, CloudVision Cognitive Unified Edge (CV-CUE) adds a new report and also includes some enhancements to existing reports.

The nexthop group feature allows users to manually configure a set of tunnels. Nexthop group counters provide the ability to count packets and bytes associated with each tunnel nexthop, irrespective of the number of times it appears in one or more nexthop groups. In other words, if a nexthop group entry shares a tunnel resource with another entry, they will also share the same counter.

Nexthop selection using GRE key allows for nexthop routing selection based on the GRE key of a GRE encapsulated IP

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

Configuration of arbitrary combinations of speeds on subinterfaces is being restricted on 800G CMIS Arista transceivers. This feature restricts configuring only uniform sets of speeds on applicable transceivers. This affects Arista-branded 800G active optical transceivers.

Vmware NSX Controllers expect Hardware VTEPs to monitor the liveness of the Replication Service Node via BFD.  In

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

With the 15.0.1 release, CV-CUE extends the wired configuration and monitoring capabilities. You can now onboard switches (710P, 720XP, 720DP) to CV-CUE. You can also configure switches and manage switch-related settings directly from the UI.

With the 14.0 release, you can integrate OpenID Connect with a captive portal for authentication. The OpenID Connect integration functionality is available only for captive portals hosted on the Arista Cloud. It is not available if the captive portal is hosted on third-party servers or on the access point.
