Network operators usually configure load balancing in their networks in order to distribute load across the links to

The CVX preserve client state feature allows client state to be preserved on CVX even when the management connection

The EOS DHCP relay agent now supports forwarding of DHCP requests to DHCP servers located in a different VRF to the DHCP

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 incorporates new capabilities, such as TAP aggregation and custom traffic engineering, alongside traditional forwarding models. DirectFlow allows users to define flows that consist of match conditions and actions to perform that are a superset of the OpenFlow 1.0 specification. DirectFlow does not require a controller or any third party integration as flows can be installed via the CLI.

EOS 4.22.1F adds support for disabling the IS IS authentication check for received IS IS PDUs. By enabling this

When passive non Dot1x speaking devices are connected to Dot1x port and it is expected that they would be

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

As of 4.22.1F Load Balance Profiles can be used to explicitly configure ECMP Load Balance parameters. In addition,

This feature supports counting ECN marked packets (ECN Explicit Congestion Notification) on a per egress port per tx

This feature is available when configuring Layer2 EVPN or EVPN IRB. As described in RFC7432 section 15

Forwarding destination prediction enables visibility into how a packet is forwarded through the switch, allowing you to determine which interfaces a packet would egress out of. Typical use cases include, but are not limited to, determining egress members for Port-Channels and ECMPs. Note that ECMPs and Port-Channels are essentially the same in terms of forwarding destinations.

Add support for IPv6 management address in LLDP. An LLDP packet requires a management address, that is typically one

This feature allows classification of packets on QoS policy-maps based on the COS/Vlan+COS bits in the 802.1q header of the packet. CoS (Class of Service) corresponds to the Priority code point (PCP) bits in the 802.1q header.

When using ingress replication, there are two possible buffer types: mini multicast buffers and full multicast
