14.6 Static Trunking Example

This example shows you how to create a static port trunk group for ports 2-5.

1 Make your physical connections - make sure that the ports that you want to belong to

the trunk group are connected to the same destination. The following figure shows ports
2-5 on switch A connected to switch B.

DESCRIPTION

Link

Aggregation

Control

Protocol

Note: Do not configure this screen unless you want to enable

dynamic link aggregation.

Active

Select this checkbox to enable Link Aggregation Control Protocol (LACP).

System

Priority

LACP system priority is a number between 1 and 65,535. The switch with the lowest

system priority (and lowest port number if system priority is the same) becomes the

LACP “server”. The LACP “server” controls the operation of LACP setup. Enter a

number to set the priority of an active port using Link Aggregation Control Protocol

(LACP). The smaller the number, the higher the priority level.

Group ID

The field identifies the link aggregation group, that is, one logical link containing

multiple ports.

LACP Active

Select this option to enable LACP for a trunk.

Port

This field displays the port number.

*

Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this

row first to set the common settings and then make adjustments on a port-by-port

basis.

Note: Changes in this row are copied to all the ports as soon as you

make them.

LACP Timeout Timeout is the time interval between the individual port exchanges of LACP packets in

order to check that the peer port in the trunk group is still up. If a port does not respond

after three tries, then it is deemed to be “down” and is removed from the trunk. Set a

short timeout (one second) for busy trunked links to ensure that disabled ports are

removed from the trunk group as soon as possible.
Select either 1 second or 30 seconds.

Apply

Click Apply to save your changes to the Switch’s run-time memory. The Switch loses

these changes if it is turned off or loses power, so use the Save link on the top

navigation panel to save your changes to the non-volatile memory when you are done

configuring.

Cancel

Click Cancel to begin configuring this screen afresh.
