I have some hosts (windows and Solaris) connected to Cisco Switch 2950.
When i capture traffic with sniffer, i can see a problem of incorrect checksum in packet and i know why (i disabled offload in my network card and all work fine).
But when i have checksum error, i don't see anything in the switche. (no input, no output, no crc... no errors) !!!
How can i detecte checksum error whitout sniffing directly in the hosts ??
ThankYou very much
