The MultiLink Trunk Utilization screen (Figures 3-27 and 3-28) allows you to 
monitor the percentage of bandwidth used by configured trunk members. You can 
choose the type of traffic to monitor.

Figure 3-27 shows an example of bandwidth utilization rates for the trunk member 
ports configured in Figure 3-26. Because two screens are necessary to show all of 
the configured trunks (up to six), the screen prompts you to Press [Ctrl]-N to view 
trunks five and six.

Choose MultiLink Trunk Utilization (or press u) from the MultiLink Trunk 
Configuration Menu to open the MultiLink Trunk Utilization screen.

Contains a single field for each row that, when enabled, allows the specified trunk to 
participate in the spanning tree. This setting overrides those of the individual trunk 
members.

Fast is the same as Normal, except that the state transition timer is shortened to two 
seconds.

Default

Normal

Range

Normal, Fast, Disabled

Contains a single read-only field for each row that indicates the default operating mode 
for the switch.

Basic: Basic mode is the default mode for the switch. When in this mode, source MAC 
addresses are dynamically assigned to specific trunk members for flooding and 
forwarding. This allows the switch to stabilize and distribute the data streams of source 
addresses across the trunk members.

Contains a single field for each row that allows users to enable or disable any of the 
trunks.

Default

Disabled

Range

Enabled, Disabled

Contains a single optional field in each row that can be used to assign names to the 
corresponding configured trunks. The names chosen for this example can provide 
meaningful information to the user (for example, S1:T1 to FS2 indicates trunk 1 in switch 
S1 connects to file server 2).
