i wrote about this last june here:

http://insearchofthecert.blogspot.com/2012/06/syslog-severity-levels.html

then i tried to give it a mnemonic... the mnemonic was too difficult to remember, go figure, so:

e a c e w n i d
0 1 2 3 4 5 6 7

docd... for this one it was easier to dig up in the switches section:

http://www.cisco.com/en/US/docs/switches/lan/catalyst3750e_3560e/software/release/12.2_55_se/configuration/guide/swlog.html

and if you're really ambitious there are a number of rfc's that document different systems (bsd) and transport (tcp, udp)... whoa...

              Table 1.  Syslog Message Facilities

   Each message Priority also has a decimal Severity level indicator.
   These are described in the following table along with their numerical
   values.  Severity values MUST be in the range of 0 to 7 inclusive.
