Table 27 MultiLink Trunk Configuration screen fields (continued)

 

 

 

Field

Description

 

 

 

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).

 

 

 

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.
