Table 10 Link Aggregation
LABEL DESCRIPTION
Link Aggregation
Link Aggregation Select the outgoing traffic distribution type. Packets from the same source and/or to the same
Algorithm destination are sent over the same link within the trunk. By default, the Switch uses the MAC SA
& DA distribution type. If the Switch is behind a router, the packet's destination or source MAC
address will be changed. In this case, set the Switch to distribute traffic based on its IP address
to make sure port trunking can work properly.
Select MAC SA to distribute traffic based on the packet's source MAC address.
Select MAC DA to distribute traffic based on the packet's destination MAC address.
Select MAC SA & DA to distribute traffic based on a combination of the packet's source and
destination MAC addresses.
Link Aggregation The field identifies the default link aggregation groups the Switch supports. Select which link
Group aggregation group supports your choice in the previous Link Aggregation Algorithm field. For
example, enabling LAG 1: Port 3 and Port 4 will allow packets from the same source and/or to
the same destination to go through ports 3 and 4 for a maximum throughput of 4 Gbps. This
allows for faster speed compared to passing packets through ports 3 and 4 individually
(maximum 2 Gbps).
Note: GS1200-5 and GS1200-5HP v2 have a link aggregation group containing ports
