(https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl):
"INFO: There have been 701876 flushes on this interface. Flushes are similar
to input drops, but are proactively forced by the router before the input
queue is full. Selective Packet Discard (SPD) is the congestion avoidance
mechanism used, where non-control packets are dropped in preference to
control packets (i.e. routing updates). Monitor the number of flushes. If
they continue to increment, consider increasing the size of the input queue
and/or improving the switching mechanism used by this interface (e.g. change
process switching to fast switching). 'Flushes' troubleshooting can be
treated similar to input drops."

Subject: Interface Flushes
Hi All,
I have 701876 flushes on show interface command. Does anyone know what
'flushes' mean? Can someone point out a link or explain in detail on what
does the counter for ? was the packet lost/dropped/forwarded ?
Thanks
Charles
