Link Aggregation 
 
The hiD 6615 S223/S323 supports two kinds of link aggregation as port trunk and LACP. 
There’s a little difference in these two ways. In case of port trucking, it is quite trouble-
some to set the configuration manually and the rate to adjust to the network environment 
changes when connecting to the switch using logical port. However, if the user configures 
physical port aggregated with the logical port in each switches, the switches are con-
nected as the configuration. Therefore it is easier for user to configure comparing to the 
port trunk and could quickly respond to the environmental changes. 
 
8.2.1 Port 
Trunk 
Port trucking enables you to dynamically group similarly configured interfaces into a sin-
gle logical link (aggregated port) to increase bandwidth, while reducing the traffic conges-
tion. 
 
8.2.1.1 
Configuring Port Trunk 
To make logical port by aggregating the ports, use the following command. 
Command Mode 
Description 
trunk
 <0-5> PORT 
Adds a port to the aggregation port group.

Bridge 
Adds a port to the aggregation group and designates 
physical port as logical port and decide which packets 
are transmitted to the aggregated port. 
1-5: Trunk Group ID 
 
For the hiD 6615 S223/S323, source destination MAC address is basically used to decide 
packet route. 
If packets enter to logical port aggregating several ports and there’s no way to decide 
packet route, the packets could be gathered on particular member port so that it is not 
possible to use logical port effectively. Therefore hiD 6615 S223/S323 is configured to 
decide the way of packet route in order to divide on member port effectively when packets
