This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

Logging - Levels


There are 8 different logging levels. Enabling higher level messages enables all lower level messages. EX: enabling Debugging level 7 enables all messages.


Level     Level Name         Description                                     Syslog Definition
0           Emergencies         The system is unusable                    LOG_EMERG
1           Alerts                   Immediate action is needed             LOG_ALERT
2           Critical                 Critical condition                             LOG_CRIT
3           Errors                  Error condition                                LOG_ERR
4          Warnings              Warning Condition                           LOG_WARNING
5          Notifications          Normal but significant condition       LOG_NOTICE
6          Informational         Informational message                     LOG_INFO
7          Debugging             Debugging message                         LOG_DEBUG

You have the option to send logging to the buffer, console, or a syslog host.
