|
|
|
|
Returns reference to hash of IIDs to admin duplex setting.
|

|
=item $alu->agg_ports()
|
|
|
|
Returns a HASH reference mapping from slave to master port for each member of

|
a port bundle on the device. Keys are ifIndex of the slave ports, Values are
|
|
ifIndex of the corresponding master ports.
