Is anyone aware of a bug or configuration that could cause a sudden
spike in IP input?
uptime is 26 weeks, 3 days, 10 hours, 54 minutes
System returned to ROM by reload at 01:40:08 PST Tue Jan 8 2008
System restarted at 01:41:34 PST Tue Jan 8 2008

Hi,
IP Input spike is usually caused by abnormal 'IP input' traffic that
gets punted into the RP from CEF for whatever reason.
A very common cause is broadcast storm. You can see what what packet
is holding the CPU with 'show buffers input interface fa0/1'. However
you need to do this command durin
Or you could load the new 12.4(20)T and set up a packet capture
on the punt path. ;)

rtp-rodunn-871#monitor captur
Hi Rodney,
Is that safe to do even if the traffic rate and/or cpu is high?
Looks like a nice feature.
