Solved: Re: Enable packet switching engine drop stats

Terry Pattinson · ‎10-02-2013

Hi all,

Does something need to be configured on a POS interface hosted on a CPP (/SIP700) to enable drop statistics or is this out indicative of a hardware limitation?

Thanks,

Terry

Hi Terry,

looking at the code it appears that this gets incremented when OCE encounters a DROP adjacency.

When we hit the drop adjacency if the packet is IPv4 or MCAST we log CPP_GLB_DROP_IPV4_UNCLASSIFIED

this is not on a per interface, it is a global counter per CPP forwarding engine.

Thanks xander, appreciate that. I saw a strong correlation between the drops recorded on the interface and show cef ipv4 drops. This answered my question.
