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： In a switching network, each of a plurality of lower tier entities is coupled to each of multiple master switches at an upper tier by a respective one of multiple links. At each of the multiple master switches, a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier are implemented on each of a plurality of ports. Each of the plurality of lower tier entities implements a respective egress port mapping indicating which of its plurality of RPIs transmits egress data traffic through each of its multiple links to the multiple master switches. In response to failure of one of the multiple links coupling a particular lower tier entity to a particular master switch, the particular lower tier entity updates its egress port mapping to redirect egress data traffic to another of the multiple master switches without packet dropping.

摘要： Each of first and second bridges of a data network having respective external links to an external node implement a network bridge component that forwards traffic inside the network and a virtual bridge component that forwards traffic outside of the 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 redirected via the ISL in response to a link-down condition of one of the external links.

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.
