Trunking permits the connection of multiple ports to the 
same remote device in order to achieve higher network 
throughput.
For link aggregation to work, the trunks must be 
configured on both ends (switches).
The Switch does not support the Link Aggregation 
Control Protocol (LACP), which is specified in IEEE 
802.3ad.
Guidelines for Creating Aggregated Links
Any of the ports on the Switch can be used for 
creating an aggregated link.
This Switch can support a maximum of 4 trunks.
Each trunk may contain up to 8 members.
A port may only be a member of one aggregated 
link at any given time.
All ports in an aggregated link must be configured in 
an identical manner, including communication mode 
(that is, speed, duplex mode and flow control). 
Defining the Members of an Aggregated Link
Use the Membership/Setup tab of the Link Aggregation 
page to specify the members of a trunk.
To define the members of a trunk:
1
On the Membership/Setup tab, select the same trunk 
number under Group Membership for the ports that 
you want to trunk.
For example, if you want ports 2, 3, 4, and 5 to 
become members of Trunk 2, set the Group Member-
ship for these ports to 2.

Click Apply.
The Status column refers to the speed and duplex mode 
of the trunk members. To change the speed and duplex 
mode of the trunk, click the Modify/Delete tab.
