A metanetwork interface name is derived from the name of the primary alternate for that metanetwork. A metanetwork interface name has the form mxxx, where xxx is the primary interface name such as le0. Some examples follow:
SCSI-2/Buffered Ethernet FSBE/S and DSBE/S (LE Ethernet) metanetwork names have the form mle#, where # is the instance number. For example, assume the network controllers le0 and le1 connect to the same Ethernet network. A metanetwork mle0 could encompass these two controllers (if the primary controller is le0). Similarly, Sun GigabitEthernet (QE Ethernet) metanetwork names have the form mqe#. Note that you cannot mix le and qe networks within the same pathgroup.
