Configuring Forwarding KHI

Forwarding KHI tracks the following on each chassis slot:
• Asic Resets
• RSP State Error Events
• RSP Stats Error Events
• F2X (F2I, F2E) Error Events
In addition, it also provides a history of the last 10 Forwarding KHI events.
The current status for each slot under Forwarding KHI is collected every 2 minutes and
indicates the health status of the slot within the previous 2 minutes.
Asic/RSP/F2X health information is monitored every 30 seconds and the information is
maintained on the line card.
Forwarding KHI information on the CP is collected every 2 minutes. Collection of this
information can have an impact when the system is busy.
The first time a particular forwarding error event occurs, it is reported as a KHI Warning
message and also logged in the Forwarding KHI Historical Data. All subsequent error events
of the same type and on the same slot-lane are not reported until a clear operation is
performed.
The memory used for Forwarding KHI information is minimal, however, collection of
Forwarding KHI information can have an impact when the system is busy. Avaya recommends
to enable Forwarding KHI when the System has stabilized.
To ensure the validity of the KHI information, verify that the timestamps are relevant.
Forwarding KHI monitoring involves reading some registers that are clear-on-read operation.
As such, debug commands that dump these registers cannot be used while Forwarding KHI
is enabled.
To configure Forwarding KHI, use the following procedure.
