Link Aggregation (LAG)
Link aggregation complying with IEEE 802.3ad bundles several physical ports together to
one logical port so that you can get enlarged bandwidth.

Link Aggregation
The V8102 supports two kinds of link aggregation as port trunk and LACP. There is a little
difference in these two ways. In case of port trunking, it is quite troublesome to set the
configuration manually and the rate to adjust to the network environment changes when
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 be automatically aggre-
gated by LACP without manually configuring the aggregated ports.
9.2.1
Port Trunk
Port trunking enables you to dynamically group the similarly configured interfaces into a
single logical link (aggregate port) to increase bandwidth, while reducing the traffic con-
gestion.
9.2.1.1
Configuring Port Trunk
To create a logical port by aggregating the ports, use the following command.
Command
Mode
Description
channel-group static
<1-12>
Interface
[XE/GE]
Creates a channel-group and adds the member ports
within a Trunk group.
channel-group active-link
<1-8>
Interface
[CG]
Specifies the number of minimum active member ports
within a Trunk (channel) group. A Trunk group is auto-
matically disabled if the operational member ports fall
at the same value or below the configured number.
1-8: the number of minimum active member ports (de-
fault:1)
channel-group distmode

Selects the distribution mode for a specified aggrega-
tion group. (default: srcdstmac)
