L—Log messages are generally displayed when the NMT records the command the user requested.
I—Informational messages generally indicate that site or link parameters have been modified to
comply with user entered data.
W—Warning messages are generally displayed when the NMT modifies connection data.
E—Error messages are generally displayed when the NMT cannot create a topology because of
incorrect data.
Example of NMT Warning Output
When you exit a data entry screen, the NMT automatically performs a line-by-line check of the data
in your table.
When you exit the Configure menu, the NMT checks your data again and, in many cases, makes
corrections. If the NMT makes any changes or finds any errors, it generates information, warning,
or error messages as needed. When this happens, you are instructed to select Warnings & Errors
from the Display menu.
If you are working with a large configuration, you may want to exit the data entry screen without
having the NMT perform a line-by-line check. To do this, press the F10 key instead of Escape
key.
When you select Route, Optimize, or Build Sites from the Execute menu, the NMT checks your
data and may make corrections. If the NMT makes any changes or finds any errors, it generates
information, warning, or error messages as needed. When this happens, you are instructed to select
Warnings & Errors from the Display menu.
