balancing the packet traffic between trunked ports. Generally, you should
select the method that can best differentiate packets that go through your
trunked ports. If you do not know which method will be the best for your
environment, use the trial-and-error approach, checking the network
monitoring windows to see which method will yield the best results in terms
of efficiency. The selected method is used as a hashing function to
determine which packets will go to which port.
Non-IP Packet <Src Mac>
For non-IP packets, the available methods are: Src Mac , Dest Mac , or Src
& Dest Mac .
IP Packet <Src Mac>
For IP packets, the available methods are: Src Mac , Dest Mac , Src & Dest
Mac , Src IP , Dest IP , or Src & Dest IP .
Port Trunking
To set up a static port trunking group, select Port Trunking on the Link Aggregation
menu:
Enter a Group ID in the first field, use the Spacebar to toggle the Member Port
field to M for each port that will be part of the trunking group, and select TRUNK in
the Method field to enable this feature. After you click APPLY , the new port
trunking group will be displayed in the table in the lower portion of the preceding
window.
The user-changeable parameters on this window are as follows:
Group ID
The switch module enables up to two port trunk groups to be configured.
The group number identifies each of these groups.
Member Port
Toggle between M to indicate membership of the port trunking group, or a
dash ( - ) to indicate non-membership.
Method <Disabled>
This field can be toggled between TRUNK and Disabled . This is used to
turn a port trunking group on or off. This is useful for diagnostics, to quickly
isolate a bandwidth intensive network device or to have an absolute backup
aggregation group that is not under automatic control.
IEEE 802.3ad Link Aggregation
Use the IEEE 802.3ad Link Aggregation menu to set up dynamic port trunking.
