    摘要： An adjunct network device includes several ports, an uplink interface, and an adjunct forwarding engine coupled to the ports and the uplink interface. A first port is configured to receive a packet, which includes a destination address. The adjunct forwarding engine is configured to send the packet to the uplink interface if the destination address is not associated with any of the ports. The packet is sent to one of the ports if the destination address is associated with the one of the ports.

    摘要： A method may involve: receiving a packet (e.g., via a port or uplink interface in a satellite switch) and conveying the packet between one or more ports and one of several uplink interfaces. The one or more ports and the uplink interface are associated with each other. The association can be independent of VLAN (Virtual Local Area Network). As an example, such a method can involve: receiving a first packet via a first port; conveying the first packet to a distribution-layer via a first uplink interface; receiving a second packet via a second port; and conveying the second packet to the distribution-layer via a second uplink interface, where the first uplink interface is associated with the first port and the second uplink interface is associated with the second port. In some embodiments, ports and uplink interfaces are associated by being assigned to the same virtual linecard.

    摘要： A virtual network device sub-unit includes an interface to a virtual network device link and a distributed forwarding module. The interface receives a packet, and the distributed forwarding module forwards the packet received by the interface. The distributed forwarding module performs an ingress lookup if the packet includes a multicast destination address and an egress lookup if the packet includes a unicast destination address. If the packet includes a multicast destination address, the distributed forwarding module replicates the packet for each of several outgoing VLANs associated with the multicast destination address. If an additional multicast packet is received via an interface that is not coupled to a virtual network device link, the distributed forwarding module sends at most one copy of the additional multicast packet via the virtual network device link.

    摘要： Various methods and systems for detecting whether a network device supports a protocol, which defines a supplemental header, are disclosed. One method involves detecting a value within a preamble generated by a sending device and verifying that a header format of a header, also generated by the sending device, conforms to a header format definition of a protocol. The header format definition of the protocol defines a supplemental header. The preamble can be an Ethernet preamble. In one embodiment, the preamble is a converged data link (CDL) preamble or other type of preamble that is used to convey operation, administration and management (OAM) information.
