The BGP-LS extension allows IGP (OSPF/IS-IS) link state database information to be injected into BGP. This is typically used in deployments where some external component, (like a controller or Path Computation Engine) can do centralized path computations by learning the entire IGP topology through BGP-LS. The controller can then communicate the computed paths based on the BGP-LS updates to the head end device in the network. The mechanism used by the controller to communicate the computed TE paths is outside the scope of this document. Using BGP-LS instead of an IGP peering with the controller to distribute IGP link state information has the following advantages.

BGP Non Stop Forwarding (NSF) aims to minimize the traffic loss when the the following scenarios occur:

EOS 4.26.1F release  added a platform configuration command to modify the dynamic MAC learning limit threshold on

For network monitoring and troubleshooting flow related issues, it is desirable to know the path, latency, queue and congestion information for flows at different times. The inband telemetry feature(INT), based on Inband Flow Analyzer RFC draft -IFA 2.0 and IFA 1.0(on some platforms) , is used to gather per flow telemetry information like path, per hop latency and congestion. INT is supported for both IPv4 and IPv6 traffic.

Media Access Control Security (MACsec) is an industry standard encryption mechanism that protects all traffic

This feature enables per port TC-To-COS mapping, where TC represents Traffic-Class and COS represents Vlan tag PCP bits. While at present there is a global TC-To-COS mapping, we can use the TC-To-COS feature to create custom profiles which can be applied to the required interfaces. 

Power over Ethernet (PoE) is a way of delivering power and data over the same Ethernet wires. There have been multiple IEEE standards for PoE over the years:

Private VLAN is a feature that segregates a regular VLAN broadcast domain while maintaining all ports in the same IP

This feature adds support for viewing the Digital Optical Monitoring (DOM) parameters for the optics that support enhanced diagnostics from the CLI. The show commands described later in this document can be used to view the instantaneous values for various modulation parameters like Signal-To-Noise Ratio, Residual Inter Symbol Interference, PAM4 Level Transition Parameters, etc. that such optics support.
