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

Using default settings for port congestion thresholds should work well in most
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 will redisplay.
Click in the Threshold % column and enter a value in the range of 1
through 99.
If no threshold is entered for a port, a default value is used that is based on port
occur the first time the events occur. Notifications are not resent while the
problem persists.
Unresolved Congestion — Click this check box to display a check mark
and enable notification. If enabled, an "unresolved congestion" entry is
made to the Event Log and an SNMP trap will be generated if trap
recipients are configured through the Configure SNMP dialog box.
An unresolved congestion event occurs when the rerouting algorithm
cannot find a path for rerouting data flow and relieving congestion on
an ISL.
