Mirror source groups
You select the sources of the traffic that you want to mirror by creating a source group, which specifies the source interfaces or sub-interfaces. Only interfaces defined in the topology as either edge links or uplinks are be available as options for sources of mirrored traffic.
Note: If an interface or sub-interface is part of a source group,
before you delete it from the topology of a fabric intent, you must first remove it
from the source group.
