摘要： A switch of a data network implements both a bridge and a virtual bridge. In response to receipt of a data frame by the switch from an external link, the switch performs a lookup in a data structure using a source media access control (SMAC) address specified by the data frame. The switch determines if the external link is configured in a link aggregation group (LAG) and if the SMAC address is newly learned. In response to a determination that the external link is configured in a LAG and the SMAC address is newly learned, the switch associates the SMAC with the virtual bridge and communicates the association to a plurality of bridges in the data network.

摘要： Each of first and second bridges of a data network having respective links to an external node implement a network bridge component that forwards traffic inside the data network and a virtual bridge component that forwards traffic outside of the data network. A virtual bridge is formed including the virtual bridge components of the first and second bridges and an interswitch link (ISL) between the virtual bridge components of the first and second bridges. Data frames are communicated with each of multiple external network nodes outside the data network via a respective one of multiple link aggregation groups all commonly supported by the virtual bridge.

摘要： A distributed device architecture includes a master device and one or more member devices. A simple network management protocol (SNMP) agent of a master device receives an SNMP request from a managing device. Where the SNMP request pertains to a given member device, and where the SNMP request requires involvement of the given member device to fulfill the SNMP request, the master device generates a non-SNMP request corresponding to the SNMP request and transmits the non-SNMP request to the given member device. A non-SNMP agent of the given member device processes the non-SNMP request and transmits processing results back to the master device. The master device generates an SNMP response corresponding to the processing results, and the SNMP agent of the master device transmits the SNMP response back to the managing device.

摘要： A switching network includes an upper tier having a master switch and a lower tier including a plurality of lower tier entities. The master switch, which has a plurality of ports each coupled to a respective lower tier entity, implements on each of the ports a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier entity coupled to that port. Data traffic communicated between the master switch and RPIs is queued within virtual ports that correspond to the RPIs with which the data traffic is communicated. The master switch applies data handling to the data traffic in accordance with a control policy based at least upon the virtual port in which the data traffic is queued, such that the master switch applies different policies to data traffic queued to two virtual ports on the same port of the master switch.
