User Manual UMN:CLIV81023239.2 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. 9.4 Link AggregationThe V8102 supports two kinds of link aggregation as port trunk and LACP. There is a littledifference in these two ways. In case of port trunking, it is quite troublesome to set theconfiguration manually and the rate to adjust to the network environment changes whenconnecting to the switch using logical port. On the other hand, in case of LACP, once youspecify LACP member ports between the switches, the ports will be automatically aggre-gated by LACP without manually configuring the aggregated ports.9.2.1 Port TrunkPort trunking enables you to dynamically group the similarly configured interfaces into asingle logical link (aggregate port) to increase bandwidth, while reducing the traffic con-gestion.9.2.1.1 Configuring Port TrunkTo create a logical port by aggregating the ports, use the following command.Command Mode Descriptionchannel-group static <1-12> Interface[XE/GE]Creates a channel-group and adds the member portswithin a Trunk group.channel-group active-link <1-8>Interface[CG]Specifies the number of minimum active member portswithin a Trunk (channel) group. A Trunk group is auto-matically disabled if the operational member ports fallat the same value or below the configured number.1-8: the number of minimum active member ports (de-fault:1)channel-group distmode{srcmac | dstmac | srcdstmac |srcip | dstip | srcdstip}Selects the distribution mode for a specified aggrega-tion group. (default: srcdstmac)
