Mapping Debug/Event Levels from VPN 3000 Series Concentrators to the ASA


The VPN 3000 Series Concentrator has 13 logging severity levels, while the ASA uses the numbers from 1 through 11, then 254 and 255 to represent different levels of debugging. In both systems, lower numbers indicate greater severity; for example, selecting a severity level of 3 in either system displays only event messages of the three greatest severity levels. Table B-1 shows the mapping between the VPN 3000 Concentrator severity levels and the ASA severity levels.

The ASA debug levels 254 and 255 have special meanings.

254 specifies IKE packet decode. This displays a Sniffer-like decoding of fields and values for each IKE packet.

255 specifies an IKE packet dump, which displays the octets within the packets.

Selecting higher-numbered levels results in the display of greater amounts of data, because the capture includes logging messages for that level and for all lower-numbered (that is, more severe) levels.

If you select level 254 or 255, the debug trace queue might overflow. To avoid this overflow, use the capture command, specifying a name for the area in memory that will hold the information and the name of the interface on which to apply packet capture, as follows:

hostname(config)# capture name type isakmp interface interface-name

This command stores the data to an area in memory, which you can then display or write to a file, then post-process to extract the information. See the description of the capture command for more information on its use.
