The network switch is configured to communicate with the first network and the second network. The controller is configured to determine whether an Ethernet packet received by the network switch from the first network or the second network is (i) an Internet Protocol (IP) multicast packet, or (ii) a media access control (MAC) multicast packet that does not encapsulate an IP multicast packet. The controller is configured to use the bridge table to route the Ethernet packet received by the network switch from the first network or the second network based on whether the Ethernet packet received by the network switch is (i) an Internet Protocol (IP) multicast packet, or (ii) a media access control (MAC) multicast packet that does not encapsulate an IP multicast packet.

摘要： A networking apparatus is used in connection with a virtual local area network (VLAN). The networking apparatus includes a control circuit and a policy circuit. The control circuit is configured to dynamically determine a count of network devices presently belonging to the VLAN. The policy circuit is configured to calculate a first data rate in proportion to the count. The first data rate is less than a total data rate of a physical network including the VLAN. The policy circuit is configured to update the first data rate in response to changes in the count. The policy circuit is configured to limit an aggregate data rate of the VLAN to the first data rate. The policy circuit is configured to update the limiting of the aggregate data rate of the VLAN in response to changes in the first data rate.

摘要： A network device includes a plurality of physical ports configured to be coupled to one or more networks, and a processor device configured to process packets. The processor device includes a processor configured to implement a logical port assignment mechanism to assign source logical port information to a data packet received via a source physical port of the plurality of physical ports. The source logical port information is assigned based on one or more characteristics of the data packet, and the source logical port information corresponds to a logical entity that is different from any physical port. The processor device also includes a forwarding engine processor configured to determine one or more egress logical ports for forwarding the data packet, map the egress logical port(s) to respective egress physical port(s) of the plurality of physical ports, and forward the data packet to the egress physical port(s) based on the mapping.

摘要： A network switch including a plurality of stack units sequentially linked to each other. Each stack unit includes a port, a forwarding engine, a first interface, and a second interface. The second interface of each stack unit is linked to the first interface of a subsequent stack unit. The second interface of a last stack unit is linked to the first interface of a first stack unit. In response to a packet traveling in a first direction from the first stack unit to the last stack unit and a link between a second stack unit and a third stack unit being inoperative, the forwarding engine of the second stack unit returns the packet in a second direction to a preceding stack unit. The packet travels in the second direction from the preceding stack unit to the first stack unit, to the last stack unit, and to the third stack unit.
