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.

System and method for a virtual chassis system

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.
