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.

Figure 64   Trunking Example - Physical Connections

2 Configure static trunking - Click Advanced Application > Link Aggregation > Link 

Aggregation Setting. In this screen activate trunking group T1 and select the ports that 
should belong to this group as shown in the figure below. Click Apply when you are 
done.

*

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.
