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.
Gerhards Standards Track [Page 10]
RFC 5424 The Syslog Protocol March 2009 Numerical Severity Code 0 Emergency: system is unusable 1 Alert: action must be taken immediately 2 Critical: critical conditions 3 Error: error conditions 4 Warning: warning conditions 5 Notice: normal but significant condition 6 Informational: informational messages 7 Debug: debug-level messages
