MultiLink Trunk Utilization screen

The MultiLink Trunk Utilization screen (

Figure 63

and

Figure 64

) allows you to

monitor the percentage of bandwidth used by configured trunk members. You can
choose the type of traffic to monitor.

Figure 63

shows an example of bandwidth utilization rates for the trunk member

ports configured in

Figure 62

. 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 screen to open the MultiLink Trunk Utilization screen.

STP Learning

The STP Learning column 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 Value

Normal

Range

Normal, Fast, Disabled

Trunk Mode

The Trunk Mode column 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, which allows the switch to stabilize and distribute the data streams of source
addresses across the trunk members.

Trunk Status

The Trunk Status column contains a single field for each row that allows users to enable
or disable any of the trunks.

Default Value

Disabled

Range

Enabled, Disabled

Trunk Name

The Trunk Name column 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).
