摘要： A system including a memory configured to store a bridge table, in which the bridge table includes an entry associating each of an Internet Protocol multicast destination address and an Internet Protocol source address with a port indicator, and the port indicator identifies one or more ports of a switch. The system further includes a controller configured to, in response to the switch receiving an Ethernet packet comprising an Internet Protocol multicast packet, i) generate a key based on each of an Internet Protocol multicast destination address and an Internet Protocol source address associated with the Ethernet packet, ii) lookup the bridge table using the key, and iii) flood the Ethernet packet to the one or more ports identified by the port indicator in response to confirming, based on the key, that the entry in the bridge table is an Internet Protocol multicast entry.

摘要： A network including a plurality of ports configured to exchange frames of data and a forwarding engine. The forwarding engine is configured to transfer the frames of data among the ports. Each frame of data includes an identifier that identifies a destination to which the frame is to be transferred by the forwarding engine. A first port of the plurality of ports includes a register configured to store an identifier of a backup port to be used in response to a failure of the first port, the backup port being among the plurality of port, and a redirect port. The redirect circuit is configured to, in response to the failure of the first port, replace the identifier in each frame of data identifying the first port as the destination port with the identifier of the backup port. Each frame having a replaced identifier is subsequently forwarded to the backup port.
