7.7.2 Link Aggregation Static
This page configures the link aggregation static group (port trunking).
Port Selection Criterion: the algorithm to distribute packets among the ports of the
link aggregation group according to source MAC address, destination MAC address,
source and destination MAC address, source IP address, destination IP address, or
source and destination IP address.
Trunk ID: a number to identify the trunk group besides the group name
Port: these port icons are listed the same way as on the front panel. You have to click
on the icon to select the group members. The port can be removed from the group by
clicking the selected port again.

The user must check the runtime link speed and duplex mode to make sure the trunk is
physically active. Go to Physical Interface and check the link mode in the runtime status
window for the trunk ports. If all the trunk members are in the same speed and full
duplex mode, then the trunk group is set up successfully. If one of the members is not in
the same speed or full duplex mode, the trunk is not set correctly. Check the link partner
and change the settings to have the same speed and full duplex mode for all the
members of the trunk group.
• All the ports in the link aggregation group MUST operate in full-duplex mode
at the same speed.
• All the ports in the link aggregation group MUST be configured in auto-
negotiation mode or full duplex mode. This configuration will make the full
duplex link possible. If you set the ports in full duplex force mode, then the
link partner MUST have the same setting. Otherwise link aggregation could
operate abnormally.
• All the ports in the link aggregation group MUST have the same VLAN setting.
• All the ports in the link aggregation group are treated as a single logical link.
That is, if any member changes an attribute, the others will change also. For
example, a trunk group consists of port 1 and 2. If the VLAN of port 1
changes, the VLAN of port 2 also changes with port 1.
