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 stackable Ethernet switch system (SESS) includes a number of stack switch elements in which loops are prevented. In one embodiment, logic is provided for monitoring control management traffic on a stacking port of a stack switch element of the SESS. Also included is logic, operable responsive to determining that there is a loss of control management traffic on a stacking port of a particular switch element of the SESS, for disabling user traffic data on that stacking port while keeping the control management traffic path open. The user data traffic on that stacking port of the particular switch element may be enabled upon detecting that the control management traffic on that stacking port has resumed.

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.
