EOS 4.27.2F TOI

The Transceiver test pattern cli can be used to check the quality of the physical layer links starting or ending at a given module. This is done by transmitting or receiving a ‘test pattern’, a pseudo-random sequence of bits that two pieces of hardware can simultaneously generate.

Virtual Private LAN Service (VPLS) appears in (almost) all respects as an Ethernet type service to customers of a Service Provider (SP). A VPLS glues together several individual LANs across a packet switched network to appear and function as a single bridged LAN. This is accomplished by incorporating MAC address learning, flooding, and forwarding functions in the context of pseudowires that connect these individual LANs across the packet switched network. LDP signaling is used for the setup and teardown of the mesh of pseudowires that constitute a given VPLS instance.

Prior to EOS 4.24.1F, per-destination steering into an SR Policy was only supported for IP unicast BGP routes in the default VRF. Support for additional AFI/SAFIs were added as follows: EOS 4.24.2F: L2 EVPN — EOS 4.27.2F: BGP Labeled Unicast
