Enabling and Configuring Open Trunking
To enable OpenTrunking for a specific switch and configure threshold values and
event notification options, use the following steps.
1. Click Configure > Open Trunking.
The Configure Open Trunking dialog box displays.
Figure 63: Configure Open Trunking dialog box
2. Click Enable Open Trunking to display a check mark and enable Open
Trunking.
3. Set the Congestion Thresholds for ports as percentages of link bandwidths,
in the range of 1% through 99%. These thresholds are used only when a port
becomes an ISL. When the link’s traffic load becomes greater than this
percentage, the link is seen as congested and traffic is rerouted (if possible) to
an uncongested link. Note that rerouting may not be possible if there are no
alternate links available, or if alternate links are congested or lack
BB_Credits.
Note: Using default settings for port congestion thresholds should work well in most
cases. Normally, you will not need to set them.
