This document explains how to configure and deploy Arista MSS with Check Point Software Technologies firewalls

This feature implements support for RFC8203/BIS so that users can attach the reason of BGP instance or peer session

On most PHYs, we run a sequence of steps in order to bring the links up reliably, because of it’s conservative nature,

In previous software releases, some interfaces on DCS 7260CX3 behaved differently from normal interfaces. When

In VXLAN EVPN deployments, a distributed anycast address is often used as the gateway address for end devices

Support for DHCPv4 (RFC 2131)  and DHCPv6 Server (RFC 8415) was added to EOS-4.22.1 and EOS-4.23.0 respectively. EOS DHCP server leverages ISC Kea as backend. The router with DHCP Server enabled acts as a server that allocates and delivers network addresses with desired configuration parameters to its hosts.

DirectFlow runs alongside the existing layer 2/3 forwarding plane, enabling a network architecture that

DirectFlow is a feature that allows the user to steer traffic by matching on packet headers and/or metadata using the

The differentiated services code point (DSCP) is a 6 bit field in the IP header, which can be used to mark traffic for

ECMP Hash visibility CLI determines the output interface for an ECMP set based on the flow parameters supplied by the

Allows user to use the CLI to configure whether or not ACL failures cause a port to become errdisabled. The default

As described in the Multi VTEP MLAG TOI, singly connected hosts can lead to suboptimal peer link utilisation. By

This feature enables support for Macro Segmentation Service (MSS) to insert security devices into the traffic path

Starting with EOS release 4.22.0F, the EVPN VXLAN L3 Gateway using EVPN IRB supports routing traffic from one IPV6

This is an addendum to the “IP in IP decapsulation” document.

An introduction to Nexthop groups can be seen in the Nexthop Group section of eos. With this feature,

This feature introduces hardware forwarding support for IPv4 over IPv4 GRE tunnel interfaces on selected Arista

This feature adds support for offloading BFD Transmit path to hardware (ASIC) for specific types of BFD sessions.

Campus hardware flow tracking allows for extensive and fine grained hardware based flow tracking and management

Hitless speed change enables changing the configured speed on one interface without impacting traffic on any of the

This feature provides support for per interface ingress/egress packet/byte counters for both IPv4 and IPv6.

In a typical switch deployment, multiple ports can have the same configuration, such as description and access VLAN.

IP Locking is an EOS feature configured on an Ethernet Layer 2 port.  When enabled, it ensures that a port will only

This features adds industry standard “unnumbered” interface support for IPv4 routed interfaces.  That means

This feature implements support for RFC6232 that helps a user identify source of an LSP purge packet. It can be enabled

LDP Hello Redundancy uses the LDP Extended Discovery Mechanism to establish a redundant targeted Hello adjacency

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

The Multicast Source Discovery Protocol (MSDP) provides a mechanism to connect together multiple PIM Sparse Mode

The TCP MSS clamping feature involves clamping the maximum segment size (MSS) in the TCP header of TCP SYN packets if it exceeds the configured MSS ceiling limit for the interface. Clamping MSS value helps in avoiding IP fragmentation in tunnel scenarios by ensuring that MSS is small enough to accommodate the extra overhead of GRE and tunnel outer IP headers.

This feature provides multipath router id, a new multipath mode to control the behavior of RPF selection. In the
