Use the Required License window to to restrict specific node instances to a subset of a domain's licensed capacity, if needed. Entries in the Required License List are optional and only apply when using network-wide domain licensing (NWDL), that is, when operating in domain license mode. When present, the entries specify limits on the license capacity allowed for the node. By default, no limits are configured; the absence of entries in the Required License List indicates that the node is entitled to use the entire capacity assigned to the SBC cluster by its NWDL license.

If you choose to specify any restrictions then you must configure appropriate limits for all counted features and also include entries for any on/off features you want to enable. If the Required License List contains a limit for any feature, any other features that are not included in the table are treated as having a license count of 0 and are effectively disabled. If you are using the full-capacity licensing option enabled by the SBC-CAPACITY-D license key, then any Max Count values you specify in Required License entries are ignored.
