352 CHAPTER 16: L INK AGGREGATION CONFIGURATION■ To guarantee a successful aggregation, ensure that the ports at the two ends ofeach link to be aggregated are consistent in selected/unselected state.Configuring a StaticLACP Link AggregationGroupFollow these steps to configure a static aggregation group:Note that:■ You can change a manual aggregation group containing no port to a staticLACP aggregation group.■ An aggregation group cannot contain ports with static MAC addresses/blackhole MAC addresses configured or 802.1x-enabled.■ Whether the destination port of a mirroring group or a port with a MACaddress learning limit can join an aggregation group depends on the model ofyour device.■ Removing a static LACP aggregation group causes LACP being disabled on allthe ports in the aggregation group.■ For static LACP aggregation group containing only one port, you can removethe port from the aggregation group only by removing the group.n When making configuration, be aware that after a load-balancing aggregationgroup changes to a non-load balancing group due to resources exhaustion, eitherof the following may happen:■ Forwarding anomaly resulted from inconsistency of the two ends in thenumber of selected ports.■ Some protocols such as GVRP malfunction because the state of the remoteport connected to the master port is unselected.Assigning a Name for anAggregation GroupFollow these steps to assign a name for an aggregation group:To do...
