Abstract
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.
