摘要： This document describes tools that withhold a data packet from a switch port despite its destination address. In one embodiment, the tools may receive a port description identifying a set of switch ports. The tools configure the set of ports so that data packets exchanged through the switch by interested entities that would otherwise be forwarded to uninterested entities are instead withheld from the uninterested entities. In another embodiment, the tools may configure a data-packet switch according to a port description identifying a set of ports and a subset of the set of ports. The tools receive a data packet that includes a broadcast destination address on a receive port and then determine, based on the port description, whether the receive port belongs to the subset. If the receive port does not belong to the subset the data packet is withheld from the other ports of the set.

摘要： Packet switch operating methods and packet switches receive, at a packet switch, a control packet from another packet switch. The packet switch and the other packet switch are coupled together by two or more tunnels. The control packet indicates that a particular one of the tunnels is active on the other packet switch. In response, the packet switch operating methods and packet switches activate the particular tunnel indicated by the received control packet on the packet switch.

摘要： Packet switch operating methods and packet switches receive a packet from a port and then forward the packet to the port from which the packet was received. The packet switch receives a packet having a first transport identifier from a port, modifies the packet to have a second transport identifier, and forwards the modified packet to the port while retaining a layer-two source address and a layer-two destination address. Other methods and packet switches transmit modified, duplicated packets on a single port. The packet switch receives a packet on a first port and creates at least one duplicate of the packet. The packet switch modifies the packet and the duplicate so that they have different transport identifiers. The packet switch then transmits the modified packets on a single port.

A packet switch receives a plurality of duplicate packets from a switching fabric and modifies two or more of the duplicate packets so that the modified duplicate packets have different transport identifiers. The packet switch then transmits one of the duplicate packets on each of a plurality of ports of the packet switch.

摘要： This document describes tools that forward data packets having tags conforming to different formats. In one embodiment, the tools receive a data packet on each of a plurality of ports, each data packet comprising a tag conforming to a different format. The tools relay the data packets to a port capable of transmitting tags conforming to a plurality of formats. In another embodiment, the tools receive a plurality of data packets on a source port comprising a plurality of logical source ports, each of which is associated with a unique tag. At least one data packet is received on each logical source port. Each data packet includes the tag associated with the logical source port on which the data packet is received. The tools map each data packet to one of a plurality of virtual switches based on the logical source port on which the data packet is received.

摘要： Element managers and processes retrieve information from a first packet switch. The information is derived from layer-two (data link layer) control packets relayed from a second packet switch to the first packet switch via a tunnel. The layer-two control packets conform to a layer-two control protocol. Based at least in part on the retrieved information, the element managers and processes determine that the tunnel is configured to relay layer-two control packets conforming to the layer-two control protocol despite a desired tunnel configuration specifying that the tunnel should not be configured to relay layer-two control packets conforming to the layer-two control protocol. Element managers and processes may alternatively or additionally detect other discrepancies between the desired tunnel configuration and the tunnel.

摘要： This document describes tools that communicate an operational state of a transport service. The transport service provides connectivity between two or more networks, enabling the networks to exchange packets. The tools detect an operational state of a transport service. After doing so, the tools may convey the operational state of the transport service to at least one of the networks through a user-to-network interface port of a network interface device, send a message to a network interface device requesting that the network interface device convey the operational state to a network connected to the network interface device, or configure a network interface device to communicate the operational state.

摘要： Network operating methods provide a first packet switch coupled to a second packet switch via a primary packet tunnel having an active status and one or more inactive backup packet tunnels having an inactive status. The methods access data describing at least one performance characteristic of the primary packet tunnel and, based at least on the data, deactivate the primary packet tunnel while still operational and activate one of the backup packet tunnels. Network operating methods provide a first device coupled to a second device via an active primary packet tunnel and one or more inactive backup packet tunnels, access data describing performance characteristics of the one or more backup packet tunnels, and, based at least on the data, deactivate the primary packet tunnel and activate one of the backup packet tunnels.
