192 CHAPTER 23: L INK AGGREGATION CONFIGURATION■ When a dynamic aggregation group or a static aggregation group is changedinto a manual aggregation group, the system will disable LACP on all themember ports automatically. When a dynamic aggregation group is changedinto a static aggregation group, LACP on all the member ports remainsenabled.Note that if a manual aggregation group or a static aggregation group containsonly one port, this port cannot be removed from the aggregation group. Instead,it can be removed from the aggregation group only in the way of removing theaggregation group.n If you use the save command to save the current configuration and then restartthe device, the configured manual/static aggregation groups and theirdescriptions still exist, however, the dynamic aggregation groups will disappearand their descriptions cannot be restored.Configuring Parametersfor HASHThrough the following configuration tasks, you can configure parameters used bythe HASH algorithm in link aggregation, thus controlling load balancing onaggregated ports effectively.n ■ All the seven parameters are available on type-A I/O Modules including3C16860, 3C16860, 3C16861, 3C16861, LS81FS24A, LS81FS24, 3C16858,3C16858, 3C16859, and 3C16859.■ None of the above seven parameters are available on non-type-A I/O Modules.■ Only type-A I/O Modules support l4port.Displaying andMaintaining LinkAggregationConfigurationAfter the above configuration, execute the display command in any view todisplay the running status after the link aggregation configuration and verify yourconfiguration.Execute the reset command in user view to clear LACP statistics on ports.Table 125 Configure parameters for HASHOperation Command DescriptionEnter system view system-view -Configure parameters used bythe HASH algorithm in linkaggregationhash { dstip | dstmac | ip |l4port | mac | srcip |srcmac } { ioboard slotslot-number | mainboard }By default, Type A I/OModules use four-tuple(dstip, dstmac, srcip andsrcmac) as the parameter ofHASH algorithm. I/O Modulesother than Type A use ip asthe parameter of HASHalgorithm.Table 126 Display and maintain link aggregation configurationOperation CommandDisplay summary information of allaggregation groupsdisplay link-aggregation summaryDisplay detailed information of a specificaggregation group or all aggregation groupsdisplay link-aggregation verbose agg-id
