UMN:CLI User ManualV5812G2248.2 Link Aggregation (LAG)Link aggregation complying with IEEE 802.3ad bundles several physical ports together toone logical port so that you can get enlarged bandwidth.Fig. 8.8 Link AggregationThe V5812G supports two kinds of link aggregation as port trunk and LACP. There is alittle difference in these two ways. In case of port trunking, it is quite troublesome to setthe configuration manually and the rate to adjust to the network environment changeswhen connecting to the switch using logical port. On the other hand, in case of LACP,once you specify LACP member ports between the switches, the ports will beautomatically aggregated by LACP without manually configuring the aggregated ports.8.2.1 Port TrunkPort trunking enables you to dynamically group the similarly configured interfaces into asingle logical link (aggregate port) to increase bandwidth, while reducing the trafficcongestion.8.2.1.1 Configuring Port TrunkTo create a logical port by aggregating the ports, use the following command.Command Mode Descriptiontrunk GID PORTSBridgeAdds a port to the aggregation group.GID: trunk group ID <0-5>trunk distmode GID {dstip |dstmac | srcdstip | srcdstmac |srcip | srcmac}Selects the distribution mode for a specifiedaggregation group. (default: srcdstmac)It is possible to input 0 to 5 to the trunk group ID because the V5812G supports 6 logicalaggregated ports, and the group ID of port trunk and the aggregator number of LACPcannot coexist.i
