SubElementFamilyName to cancel

This field contains a list of any SubElementFamilyNames that must not be used with this sysObjectID.

For the Redback example, the SubElementFamilyNames to be ignored are: Generic_Lan_Ethernet10, Generic_Lan_Ethernet100, and Generic_Lan_Ethernet1000.

If you leave this blank, the same subelement can appear under two different groups, the vendor-specific group and a generic group. If you add information, the Inventory Tool ignores the canceled formulas not only for this type of subelement but for all subelements found on the element being processed.

If you cancel a generic rule that can be applied to more than one type of interface, and the Inventory Tool finds a subelement that does not match any of your device-specific rules but would have matched the canceled generic rule, that subelement is not discovered.

For example, if Generic_Node is included in the SubElementFamilyName to cancel field for the Redback example, the Inventory Tool only discovers Redback ethernet interfaces. If the element contains other types of subelements, such as ATM, none of the other subelements are discovered.
