Techniques for validating configuration changes in a mixed node topology are provided. In one embodiment, a device can identify a link to be removed from a topology comprising a plurality of nodes, where the plurality of nodes includes one or more nodes of a first type and one or more nodes of a second type. The device can then determine whether the removal of the link from the topology would require data traffic between two nodes of the first type to pass through a node of the second type.

Techniques for reducing broadcast and multicast traffic in a stacking system are provided. In one embodiment, a master device in the stacking system can automatically determine a minimal set of VLAN associations for stacking links in the stacking system. The minimal set of VLAN associations can avoid unnecessary transmission of broadcast or multicast packets through the system's topology.

Techniques for assigning device identifiers in a system of devices are provided. In one embodiment, a master device of the system can maintain a first configuration that specifies a set of links between a first subset of the devices, where the first configuration includes a device identifier for each device in the first subset. The master device can further generate a second configuration that specifies a set of links between a second subset of the devices, where the second configuration is based on a physical topology of the system, and where one or more devices in the second subset are unknown devices that are not associated with a device identifier in the physical topology. The master device can then assign device identifiers to the unknown devices in the second subset by comparing the first configuration with the second configuration.
