Transmit queues are logical partitions of an Ethernet port’s egress bandwidth. Data streams are assigned to queues based on their traffic class, then sent as scheduled by port and transmit settings. Sand platform switches have eight queues, 0 through 7, and all queues are exposed through the CLI. However, queue 7 is not user-configurable. Queue 7 is always mapped to traffic class 7, which is reserved for control plane traffic. This feature allows tx-queue 7 to be configurable. As of 4.33.0F, a limited set of features are configurable on tx-queue 7.

The sFlow VPLS extension adds support for providing VPLS-related information to sFlow packet samples, for VPLS forwarded traffic. Specifically, for customer traffic ingressing on a CE-facing PE interface in a VPLS deployment that uses statically configured LDP pseudowires, information such as the name of the VPLS instance and the ID of the pseudowire that the packet will egress over will be included in the sFlow datagram.

Split horizon groups (SHG) may be used to divide all subinterfaces and VPLS pseudowires in a VLAN to different bridging groups so that bridging is prevented between members of the same SHG. Bridging is allowed between members of different SHGs and subinterfaces which don’t belong to any SHG.

Virtual Private LAN Service (VPLS) can be used when one wishes to connect several LANs dispersed across a packet switched network. VPLS can allow the dispersed LANs to act like a single bridged LAN by providing a service to connect the LANs. The service will appear like an Ethernet LAN (in almost all regards). VPLS achieves this by creating a mesh of pseudowires that connect the dispersed LANs, while also processing the traffic that moves through the pseudowires in a similar way to how a L2 service would. For example, MAC address learning, flooding and forwarding functions are applied to the pseudowire traffic in a VPLS. This allows VPLS to mimic the functionality of an any-to-any L2 service when connecting dispersed LANs.

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.
