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

Security MAC ACLs can be used to permit and/or deny ethernet packets on the egress port by matching on the following

E-Tree is an L2 EVPN service (defined in RFC8317) in which each attachment circuit (AC) is assigned the role of Root or Leaf. Once roles are assigned, the following forwarding rules are enforced:

EVPN MPLS VPWS (RFC 8214) provides the ability to forward customer traffic to / from a given attachment circuit (AC) without any MAC lookup / learning. The basic advantage of VPWS over an L2 EVPN is the reduced control plane signalling due to not exchanging MAC address information. In contrast to LDP pseudowires, EVPN MPLS VPWS uses BGP for signalling. Port based and VLAN based services are supported.

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

The hardware based implementation of the firewall uses a segment security model. In the segment security model,

On network devices, when a route is programmed, a certain portion of hardware resources is allocated and associated

IP Locking is an EOS feature configured on an Ethernet Layer 2 port.  When enabled, it ensures that a port will only permit IP and ARP packets with IP source addresses that have been authorized. As of EOS-4.25.0F release update, IP Locking can run in two modes - IPv4 Locking (which will be referred to as IP Locking) and IPv6 Locking, which can be configured using the commands mentioned in the below sections. IP Locking prevents another host on a different interface from claiming ownership of an IP address through either IP or ARP spoofing.

The IS IS maximum LSP size feature provides the ability to configure the maximum LSP size that the IS IS protocol will

Level 1 2 routers set attached bit in their Level 1 LSPs to indicate their reachability to the rest of the network. A

MAP T is a double stateless NAT64 translation technology. It allows an internet service provider to share IPv4

Network address translation (NAT) is a common method used to remap one IP address space into another by modifying the

When there are multiple VRFs on the device and there is a need to share routes between them, typically for shared

VRF Route leaking can be used when routes from one VRF are required in another VRF (e.g. in case of shared services). If VrfLeak Agent is being used to leak routes, the leaked routes (in destination VRF) can be redistributed into IGPs.

In addition to aliasing only the first token in a CLI command, EOS now supports full command aliasing using regular
