Message
SEP/3/PREEMPT_REQ_FAIL:Preemption failed because
the number of preempt request packets reached the upper limit. (preempt
number=[ULONG])
Description
Preemption failed because the number of preemption
request packets reached the upper limit.
Parameters
Parameter Name
Parameter Meaning
preempt number
Number of preemption request packets
Possible Causes
Cause 1: Failed to send preemption request packets.
Cause 2: The peer device failed to receive preemption request
packets.
Procedure
Cause 1: Failed to send preemption request packets.
The chip of the device may fail. In this case, collect configurations
and log messages, and then contact technical support personnel.
Cause 2: The remote device failed to receive preemption
request packets.
Run the reset sep interfaceinterface-type interface-numberstatistics command on the local and remote devices
to clear the statistics about the SEP protocol packets on the specified
interface on the SEP segment.
Run the display sep interfaceinterface-type interface-number [ verbose ] command on the local device to view the PREEMPT REQ TLV field. Check whether there is count displayed
in the tx sub-field.
If there is count displayed in the tx sub-field in the PREEMPT REQ TLV field, it indicates that the local device has
sent preemption request packets. In this case, go to c.
If there is no count displayed in the tx sub-field in the PREEMPT REQ TLV field, it indicates that the local device has
not sent preemption request packets. In this case, go to e.
Run the display sep interfaceinterface-type
interface-number [ verbose ]
command on the remote device to view the PREEMPT ACK TLV field.
Check whether there is count displayed in the rx sub-field.
If there is count displayed in the rx sub-field in the PREEMPT ACK TLV field, it indicates that the remote device has
received preemption request packets. In this case, go to e.
If there is no count displayed in the rx sub-field in the PREEMPT ACK TLV field, it indicates that the remote device has
not received preemption request packets. In this case, go to d.
Check whether the link frequently alternates
between Up and Down states.
If the link frequently alternates between Up and Down states,
replace the hardware or optical fibers.
