aggregating a number of the ports.
Fig. 8.7 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.
trunk distmode <0-5> PORTS
{dstip | dstmac | srcdstip |
srcdstmac | srcip | srcmac}
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
