2.6.4 Interface groups
Interface groups filter interfaces within nodes by ifType or by other attributes, such as ifAlias, ifDescr, ifName, ifIndex, IP address, and so forth. Interface groups carry no hierarchy or containment, although you can further qualify membership based on the node group for the node hosting the interface.
Interface groups can be filtered on custom capabilities and attributes similarly to node groups.
Qualifications for interface groups are AND'd together within and across tabs.
There is an NNMi limitation when an interface group whose definition contains dependencies on aggregated link capabilities is used in the Discovery Excluded Interfaces configuration. In this case, the interfaces will not always be excluded.
