EOS 4.23.1F TOI

Enough fabric capacity is needed to sustain line rate traffic of front panel ports of each switch element (FAP).

EOS 4.23.1F added basic MLAG support for 7800R3, 7500R3 and 7280R3 platforms. The MLAG features that are currently

EOS 4.21.3F introduces support for BGP Flowspec, as defined in RFC5575 and RFC7674. The typical use case is to filter or redirect DDoS traffic on edge routers.

In the multi agent routing protocol model, the Bgp agent now supports matching community lists with a logical OR via

BGP Monitoring Protocol (BMP) allows a monitoring station to connect to a router and collect all of the BGP announcements received from the router’s BGP peers. The announcements are sent to the station in the form of BMP Route Monitoring messages generated from path information in the router’s BGP Adj-Rib-In tables.

This feature adds support for user configured BGP Nexthop Resolution RIB profiles for various BGP based services

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.

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

This command stores and displays a list of failed BGP connection attempts for each peer. This may be particularly

The ‘show interfaces interactions’ command aims to provide users a resource that explains various relationships between ethernet interfaces. It describes interactions in which a configuration on an interface causes another set of interfaces to become inactive or have reduced capabilities.Examples include a primary interface consuming subordinate interfaces to service a four-lane speed or platform restrictions that require four interfaces of a port to operate at the same speed.

SNMP IP address ACL support provides the ability to add access lists to limit the source addresses that can be used to

This feature adds three new SNMP traps for MAC move, learn, and age events: aristaMacMove, aristaMacLearn, and
