We have a 7206 that is getting lots of input errors and overrun errors
on the LAN side without CRC errors. On the WAN side we are getting
all 3 but on a much smaller scale. Every couple of weeks the CPU goes
through the roof but the box has never rebooted. Can anyone give me a
detailed breakdown of what I should be looking for here?
The 7200 runs:
BGP for 200Mb/s provider MPLS circuit (not full BGP table)
OSPF
IP CEF
QoS
and you can see the two circuits below....
