Hi, I have a 6509 running 12.2(18)SXF4. I find a lot of the following errors in the logs
%MLS_STAT-SP-4-IP_CSUM_ERR: IP checksum errors %EARL_L3_ASIC-SP-3-INTR_WARN: EARL L3 ASIC: Non-fatal interrupt Packet Parser block interrupt >From what I read, these are informational (http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a00801b42bf.shtml#EARL) While as per the above I could disable the informational message I could also try to locate and fix the problem. I don't imagine SPAN will actually SPAN packets with IP header checksum errors and even if it does it seems it may be hard to get a sniffer that has an OS that will not also discard the packets. I was wondering if anyone had any ideas or experience with this. Also using ELAM (http://cisco.cluepon.net/index.php/Using_capture_buffer_with_ELAM or https://supportforums.cisco.com/message/3006679?tstart=-1) would be good. I am not sure if the filter can be set to packets with IP header checksum errors either....
