So here is the command i have a question about:(hopefully this pastes correct)

R4(config)#logging trap ?

<0-7> Logging severity level

alerts Immediate action needed (severity=1)

critical Critical conditions (severity=2)

debugging Debugging messages (severity=7)

emergencies System is unusable (severity=0)

errors Error conditions (severity=3)

informational Informational messages (severity=6)

notifications Normal but significant conditions (severity=5)

warnings Warning conditions (severity=4)

<cr>

The question i have is: How do i know what is logged under say level 3 vs level 4? I cant seem to find this info anywhere. This would be for switches and routers.
