Function (when enabled)
Enables the open trunking option
Sets the congestion threshold levels for ports as
percentages (1%—99%) of link bandwidths. When
the link's traffic load becomes congested, traffic is
rerouted (if possible) to an uncongested link. Two
options are available:
• Select the check box under the Use Algorithmic
Threshold column to use a value computed by the
rerouting algorithm.
• Click in the Threshold % column, and enter a
value in the range of 1 through 99.
Identifies the type of events that result in an event log
entry, and generates an SNMP trap. The notifications
occur on first instance only. The event notification
types are:
• Unresolved congestion—The rerouting algorithm
cannot find a path for rerouting data flow to
relieve congestion.
• Back Pressure—The low BB_credit threshold has
been exceeded.
Defines the acceptable percent of time that the
transmitting link has no BB_credit. Two options are
available:
• Default threshold value
• User-defined threshold value
