SWITCHINGENGINEMAN Messages
Error Message C4K_SWITCHINGENGINEMAN-3-PPELEAKDETECTED: Hardware buffer leak
detected. System will be reset!
Explanation
A PPE leak was detected, and the system will reset. This may be due to a transient
hardware problem with the packet buffer related memories. This message may also erroneously
appear if using jumbo packets or if sharing is configured and transmit queues have backed up.
Recommended Action This is an informational message only. No action is required. To suppress the
automatic reset action use the diagnostic monitor action conservative command.
Error Message C4K_SWITCHINGENGINEMAN-7-PPELEAKMONITOR: Current Freelist count %u.
Fell below threshold %u times consecutively
Explanation
The PPE freelist count is being monitored. Packet buffer leak detection is on and the
freelist count is being monitored. This message displays the current count and number of times the
count reached the threshold. If the freelist count stays below the threshold for more than one minute,
the system will be reset.This message may also erroneously appear if using jumbo packets or if
sharing is configured and transmit queues have backed up.
Recommended Action This is an informational message only. No action is required. To suppress the
automatic reset action use the diagnostic monitor action conservative command.
Error Message C4K_SWITCHINGENGINEMAN-3-RDPMEOPMISMATCHERROR: RdPMEopMismatch error
, subcell addr=[hex], reg bits=[hex], total errors=%u
Explanation
An error in a packet's cell was detected. This could indicate a problem with the packet
cell linked list or subcell count memory. If this message persists, it may indicate a transient hardware
problem, or a more permanent problem. After 1024 such End-Of-Packet mismatch errors, the switch
will reload.
Recommended Action After 1024 such End-Of-Packet mismatch errors, the switch will reload. If the
switch is reloading too often due to this condition, you may need to check for environmental
conditions such as RFI or other interference. It may also be necessary to replace the supervisor
engine.
Error Message C4K_SWITCHINGENGINEMAN-3-SUBCELLCNTMEMORYPARITYERROR: Parity error in
subcell count memory, addr=[hex], reg bits=[hex], total errors=%u
Explanation
An error in subcell count memory was detected. If this message persists, it may indicate
a transient hardware problem, or a more permanent problem. After 128 such subcell count errors,
the switch will reload.
Recommended Action If the switch is reloading too often due to this condition, you may need to check
for environmental conditions such as RFI or other interference. It may also be necessary to replace
the supervisor engine.
