3. Choose Enabled in the Open Trunking State drop down list.
4. Choose Enabled or Disabled from the Unresolved Congestion Event
Notification drop down list. If enabled, an unresolved congestion entry is
made in the event log and, if SNMP is configured, an SNMP trap is generated.
Unresolved congestion occurs when a flow cannot be rerouted to another link
because it would exceed the other link's threshold.
5. Choose Enabled or Disabled from the Backpressure Event Notification
drop down list. If enabled, a backpressure entry is made in the event log and,
if SNMP is configured, an SNMP trap is generated. Backpressure occurs
when the threshold of unavailable BB_Credits is exceeded for any link.
6. Specify a value for the Low BB Credit Threshold option, if desired.
