The comparison module 48 may be operable to access a set of supported configuration options 54. The supported configuration options 54 may be associated with the respective layers and/or sublayers of the network connectivity model. The configuration options 52 may include at least the supported configuration options 54. The set of supported configuration options 54 may be associated with fewer than all configuration options 52 of the respective groups of configuration options 52. The groups of configuration options 52 may define a set of selectable combinations associated with two or more of the layers and/or sublayers of the network connectivity model. The set of supported configuration options 54 may define a set of supported combinations associated with two or more of the layers and/or sublayers of the network connectivity model. The set of supported combinations may be fewer than all selectable combinations of the set of selectable combinations of the configuration options 52.
