6.15 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.



6.15.1 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 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 which 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.

 Select the ports to join the trunk group. The system allows a maximum of four ports to
