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 4 ports into one 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
System Priority:
A value which is used to identify the active LACP. The switch with
the lowest value has the highest priority and is selected as the active LACP.
Group ID:
There are four trunk groups to be selected. Choose the "
Group ID
" and
click
Select
.
LACP:
When enabled, the trunk group is using LACP. A port which joins an LACP
trunk group has to make an agreement with its member ports first. When disabled,
the trunk group is a static trunk group. The advantage of having the LACP disabled
is that a port joins the trunk group without any handshaking with its member ports.
But member ports won’t know that they should be aggregated together to form a
logic trunk group.
Work ports:
This column field allows the user to type in the total number of active
port up to four. With LACP static trunk group, e.g. you assign four ports to be the
members of a trunk group whose work ports column field is set as two; the exceed
ports are standby (the
LACP State Activity
will show ‘Passive’ on the tab of
State
Activity
) and can be aggregated if work ports fail. If it is a static trunk group, the
number of work ports must equal the total number of group member ports.
Select the ports to join the trunk group. The system allows four ports maximum to
be aggregated in a trunk group. Click
