Instead of statically assigning access VLAN on the authenticator port, it's sometimes desirable to offload the work

MAC Based Authentication is a facility which allows a set of MAC addresses to be programmed into the RADIUS server.

This feature allows the DHCP relay agent to insert or modify Converged Cable Access Platform (CCAP) Core IPv6

EOS's architecture is built around the notion of agents. While the CLI show commands offer great insights into the

In VXLAN EVPN deployments, a distributed anycast address is often used as the gateway address for end devices connected to the Vxlan Tunnel End Points (VTEPs). Similarly, in MLAG configurations in a VXLAN environment, ip address virtual could be used on both MLAG peers.

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

EOS 4.20.5F introduces support for disabling local interface, when a fault is signaled by the remote peer. The

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

EOS-4.20.5 adds support for hardware-accelerated sFlow on compatible R2 platforms.

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

The route map feature 'invert result' has been added to the 'match community' and 'match extcommunity' statements

Similar to L4 ports, ACL rules can be configured to filter ingress packets based on their IP length (present in the IPv4

IS-IS Counters feature adds support to monitor per interface count of received, transmitted and dropped IS-IS PDUs at the Rib/ISIS agent level. The counters start getting incremented once IS-IS is enabled on an interface and persist until IS-IS is disabled on it or the Rib/Isis agent restart.

The partial SPF computation avoids a full shortest path computation to achieve quicker convergence and save CPU load

This document describes two features that allow dynamic metric change for IS IS based on interface speed.

Traffic Engineering (TE) provides a mechanism to network administrators to control the path that a data packet takes, bypassing the standard routing model which uses routes along the shortest path. Traffic engineered paths are generally computed on the head-end routers of the topology based on various constraints (e.g. minimum bandwidth, affinity) configured for those paths and attributes (e.g available bandwidth, color) received from devices in the network topology. IS-IS Traffic Engineering (IS-IS TE) feature extends IS-IS protocol in EOS to carry TE attributes as part of its Link State Protocol Data Units (LSPs).  Note that IS-IS in EOS only acts as a carrier for TE attributes and it is not used by any processing (e.g. SPF).

The L2EVPN MPLS feature is available when configuring BGP in the multi agent routing protocol model.

The L2EVPN MPLS feature is available when configuring BGP in the multi agent routing protocol model. Ethernet VPN

Introduced in EOS 4.20.5, LAG hashing key shift controls how many bits we shift the LAG load balance key.

LANZ adds support for configuring global thresholds for Ethernet ports on DCS 7020, DCS 7050TX, DCS 7050X2, DCS

Leaf Smart System Upgrade (SSU) provides the ability to upgrade the EOS image with minimal traffic disruption.Note: It is possible that SSU shutdown and bootup are not supported in the same image. If a product has shutdown support in image A and bootup support in a later image B, then SSU upgrade cannot be performed from image A to any images earlier than image B, including image A itself. However, upgrading from image A to image B onwards is allowed.

The management tech support policy provides the capability to efficiently manage the output of "show tech support"

MLAG Smart System Upgrade (SSU) provides the ability to upgrade the EOS image of an MLAG switch with minimal traffic disruption.
