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).
