Port Trunk
Port trunking is the combination of several ports or network cables to expand the
connection speed beyond the limits of any one single port or network cable. Link
Aggregation Control Protocol (LACP), which is a protocol running on layer 2, provides a
standardized means in accordance with IEEE 802.3ad to bundle several physical ports
together to form a single logical channel. All the ports within the logical channel or so-
called logical aggregator work at the same connection speed and LACP operation
requires full-duplex mode.
Aggregator setting
System Priority:
A value that is used to identify the active LACP. The switch with
the lowest value has the highest priority and is selected as the active LACP peer of
the trunk group.
Group ID:
There are 13 trunk groups to be selected. Assign the "
Group ID
" to the
trunk group.
LACP:
When enabled, the trunk group is using LACP. A port that joins an LACP
trunk group has to make an agreement with its member ports first. Please notice that
a trunk group, including member ports split between two switches, has to enable the
LACP function of the two switches. 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/redundant ports and can be aggregated if working ports fail. If it is
a
static trunk group
(non-LACP), the number of work ports must equal the total
number of group member ports.
