Link Aggregation
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 switch supports two kinds of link aggregation as port trunk and LACP. There's 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.
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.
Configuring Port Trunk
To create a logical port by aggregating the ports, use the following command.
Command
trunk <0-4> PORTS
trunk distmode { srcdstip |
srcdstmac | srcdstl4 }
Enlarged bandwidth
with many ports
A logical port that can be made by
aggregating a number of the ports.
Mode
Adds a port to the aggregation group.
0-4: trunk group ID
Selects the distribution mode for a specified aggrega-
tion group.
Bridge
srcdstmac: refers to source MAC address and destina-
tion MAC address.
srcdstip: refers to source and destination IP address.
srcdstl4: refers to source and destination TCP/UDP.
