2. Enable Open Trunking by clicking the Enable Open Trunking check box to
display a check mark.
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 have no available
BB_Credit.
Note: Using default settings for port congestion thresholds should work well in most
cases. This step is not required.
Set the Congestion Threshold using one of these methods:
■
Click the check box under the Use Algorithmic Threshold column to
display a value under the Threshold % column. This value is computed
by the feature’s rerouting algorithm. If you click this check box, you
cannot enter a value into the Threshold % column for the port.
■
If you click the check box to remove the check mark, any value that was
set in the Threshold % column for the port redisplays.
