Port Trunk
The Link Aggregation Control Protocol (LACP) provides a standardized means for
exchanging information between Partner Systems on a link to allow their Link Aggregation
Control instances to reach agreement on the identity of the Link Aggregation Group to
which the link belongs, move the link to that Link Aggregation Group, and enable its
transmission and reception functions in an orderly manner. Link aggregation lets you
group up to nine consecutive ports into a single dedicated connection. This feature can
expand bandwidth to a device on the network. LACP operation requires full-duplex
mode, more detail information refers to IEEE 802.3ad.
Aggregator setting
1. System Priority: a value used to identify the active LACP. The switch with the lowest
value has the highest priority and is selected as the active LACP.
2.
Group ID:
There are seven trunk groups to provide configure. Choose the "
Group
ID
" and click
Select
.
3. LACP: If enable, the group is LACP static trunk group. If disable, the group is local
static trunk group. All ports support LACP dynamic trunk group. If connecting to the
device that also supports LACP, the LACP dynamic trunk group will be created
automatically.
4. Work ports: allow max four ports can be aggregated at the same time. If LACP static
trunk group, the exceed ports are standby and able to aggregate if work ports fail. If it
is local static trunk group, the number must be as same as the group member ports.
5. Select the ports to join the trunk group. Allow max four ports can be aggregated at the
same time. Click
Add
button to add the port. To remove unwanted ports, select
the port and click
Remove
button.
