Chapter 3 Using the console interface 137Using the BayStack 420 10/100/1000 SwitchMultiLink Trunk Utilization screenThe MultiLink Trunk Utilization screen (Figure 63 and Figure 64) allows you tomonitor the percentage of bandwidth used by configured trunk members. You canchoose the type of traffic to monitor.Figure 63 shows an example of bandwidth utilization rates for the trunk memberports configured in Figure 62. Because two screens are necessary to show all ofthe configured trunks (up to six), the screen prompts you to Press [Ctrl]-N to viewtrunks five and six.Choose MultiLink Trunk Utilization (or press u) from the MultiLink TrunkConfiguration 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 thoseof the individual trunk members.Fast is the same as Normal, except that the state transition timer is shortened to twoseconds.Default Value NormalRange Normal, Fast, DisabledTrunk Mode The Trunk Mode column contains a single read only field for each row that indicates thedefault operating mode for the switch.Basic: Basic mode is the default mode for the switch. When in this mode, source MACaddresses are dynamically assigned to specific trunk members for flooding andforwarding, which allows the switch to stabilize and distribute the data streams of sourceaddresses across the trunk members.Trunk Status The Trunk Status column contains a single field for each row that allows users to enableor disable any of the trunks.Default Value DisabledRange Enabled, DisabledTrunk Name The Trunk Name column contains a single optional field in each row that can be used toassign names to the corresponding configured trunks. The names chosen for thisexample can provide meaningful information to the user (for example, S1:T1 to FS2indicates Trunk 1, in switch S1 connects to File Server 2).Table 27 MultiLink Trunk Configuration screen fields (continued)Field Description
