82Shutting down an aggregate interfaceShutting down or bringing up an aggregate interface affects the aggregation state and link state of portsin the corresponding aggregation group in the following ways:• When an aggregate interface is shut down, all Selected ports in the corresponding aggregationgroup become unselected and their link state becomes down.• When an aggregate interface is brought up, the aggregation state of ports in the correspondingaggregation group is recalculated and their link state becomes up.To shut down an aggregate interface:Step Command Remarks1. Enter system view. system-view N/A2. Enter aggregate interfaceview.• Enter Layer 2 aggregate interfaceview:interface bridge-aggregationinterface-number• Enter Layer 3 aggregate interfaceor subinterface view:interface route-aggregation{ interface-number |interface-number.subnumber }Use either command.3. Shut down the aggregateinterface or subinterface. shutdown By default, aggregate interfacesor subinterfaces are up.NOTE:Shutting down an aggregate subinterface does not affect any aggregation group, because an aggregatesubinterface does not have an associated aggregation group.Restoring the default settings for an aggregate interfaceTo restore the default settings for an aggregate interface:Step Command Remarks1.
