摘要： A virtual chassis system includes a plurality of network nodes configured with a master virtual chassis address. The network nodes are connected by virtual fabric link (VFLs) that provide a connection for exchange of packets between the network nodes. The packets include source MAC addresses and associated hardware device information, such as source chassis ID, source network interface identifier and source port identifier information. The network nodes use this information to maintain synchronized MAC address tables for forwarding of packets in the virtual chassis system.

摘要： A virtual chassis system includes a plurality of network nodes connected by virtual fabric link (VFLs) that provide a connection for exchange of packets between the network nodes. A network node in the virtual chassis system is operable in a pass thru mode. In pass thru mode, the network node receives packets over a VFL and transparently forwards the packet over another VFL to another network node in the virtual chassis system. However, the network node 110 disables other port interfaces, such as port interfaces connected to external nodes from the virtual chassis system. The network node 110 in pass thru mode is operable to receive management commands over one or more VFLs and can still be managed through management commands.

摘要： A virtual chassis system includes a plurality of network nodes configured with a master virtual chassis address. The network nodes are connected by virtual fabric link (VFLs) that provide a connection for exchange of packets between the network nodes. The virtual chassis system is operable to provide warnings to help prevent a virtual chassis split event in response to an administrative action. The topology of the virtual chassis system is analyzed to determine the possible impact of one or more administrative actions. Based on this analysis, a warning is generated when an administrative action is requested that may lead directly or indirectly to a virtual chassis split.

摘要： Aggregation Switches connected via a virtual fabric link (VFL) are each active and able to communicate via an inter-process communication (IPC) using an IPC Virtual Local Area Network (IPC VLAN). A sub-set of Customer-facing ports (CFPs) of each Aggregation Switch are coupled to the VFL and assigned to the IPC VLAN to enable communication therebetween.

摘要： Aggregation switches are connected to an edge node by a multi-chassis link aggregation group and a virtual fiber link provides a connection for exchange of information between the aggregation switches regarding MAC addressing to synchronize MAC address tables across the aggregation switches. When failure of the virtual fiber link is detected, the multi-chassis link aggregation group is reconfigured into two or more link aggregates with each link aggregate connecting the edge node to one of the aggregation switches. A spanning tree protocol is initiated over the link aggregates to prevent loops in the network. MAC address tables are flushed and relearned with the two or more link aggregates.
