Troubleshooting the ASA 5585-X IPS SSP

Appendix C Troubleshooting

This miscount is a result of header bytes added to the packet by the ASA before the packet is transmitted to the IPS. For IPv4, 58 bytes of header data are added. For IPv6, 78 bytes of header data are added. The ASA removes the added IPS header before the packet leaves the ASA.

Note Before troubleshooting the ASA 5585-X IPS SSP, check the Caveats section of the Readme for the software version installed on your sensor to see if you are dealing with a known issue.
