1.
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.
2.
Group ID:
There are four trunk groups to be selected. Choose the "
Group ID
" and
click
Select
button.
3.
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 m ember ports won’t k now t hat they s hould be aggregated t ogether t o form a
logic trunk group.
4.
Work ports:
This column field allows the user to type in the total number of active
port up t o four. With LACP static trunk group, e.g. you assign four ports to be t he
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.
5. Select the ports to join the trunk group. The system allows four ports maximum to
