DVS Series Managed Industrial Ethernet Switches User’s Manual
3.9 Port Trunking
Port Trunking can help you to aggregate more links to form one link group. Delta DVS switch’s LAG
function supports 3 trunk groups, and you can assign 8 ports to one group. But there is a limit of 3
gigabit ports or 7 10/100Mbps ports for each lag ID. Link Aggregation (LA) increases the capacity
and availability of the communication channel between devices (both switches and end stations)
using existing Fast Ethernet and Gigabit Ethernet technology. LA also provides load balancing
where the processing and communication activity is distributed across several links in a trunk.
If there are 4 ports in a trunk group, and one port fails, then the other seven ports will provide
backup and share the traffic automatically. LA also can be used to combine 4 ports between Delta
DVS switches. If all ports on these two switches are configured as 100BaseTX and full duplex, then
the potential bandwidth of the connection can be 400Mbps.

IMPORTANT:
Make sure that you save the configuration in the Save
Configuration page after you have applied the configuration
changes. (Save ConfigSave Configuration) If you don’t
save the configuration, then the configuration will be cleared
after the switch
is rebooted

3.9.1 LAG
Link aggregation groups (LAGs) let you combine multiple full-duplex Ethernet links into a single
logical link. LAG increases fault tolerance and provide traffic sharing. You can assign LAG VLAN
membership after you have added interfaces as members of a LAG.
After you have added interfaces to a LAG and enabled the LAG, Link Aggregation Control Protocol
(LACP) can automatically configure a port channel link between the switch and another device.
