Figure 2-104 Configure Panel (Performance Page with OpenTrunking Tab)
a. At the OpenTrunking State field, select Enabled or Disabled.
When this parameter is enabled, the optional OpenTrunking
feature is functional.
b. At the Unresolved Congestion Event Notification field, select
Enabled or Disabled. When this parameter is enabled,
unresolved congestion events are recorded in the event log,
and SNMP trap messages are generated and transmitted (if
SNMP is configured).
An unresolved congestion event occurs for a low-BB_Credit
ISL when the switch’s firmware rerouting algorithm cannot
route data flow to an alternate path (because doing so would
exceed the alternate path’s low BB_Credit threshold).
c. At the Backpressure Event Notification field, select Enabled or
Disabled. When this parameter is enabled, backpressure events
are recorded in the event log, and SNMP trap messages are
generated and transmitted (if SNMP is configured).
A backpressure event occurs when the percent time an ISL has
low BB_Credit exceeds the low BB_Credit threshold.
