Cisco Systems 1000 Series Manual De Usuario

Tracing cannot be disabled on the Cisco ASR 1000 Series Router. Trace levels, however, which set the 
message types that generate trace output, are user-configurable and can be set using the platform trace 
commands. If a user wants to modify the trace level to increase or decrease the amount of trace message 
output, the user should set a new tracing level using the platform trace commands. Trace levels can be 
set by process using the all-modules keyword within the platform trace commands, or by module 
within a process. See the platform trace command reference for more information on this command, 
and the 

 of this document for additional information on tracing 

levels.

Tracing levels determine how much information about a module should be stored in the trace buffer or 
file.

 shows all of the trace levels that are available and provides descriptions of what types of messages are 
displayed with each tracing level.

Trace level settings are leveled, meaning that every setting will contain all messages from the lower 
setting plus the messages from its own setting. For instance, setting the trace level to 3(error) ensures 
that the trace file will contain all output for the 0 (emergencies), 1 (alerts), 2 (critical), and 3 (error) 
settings. Setting the trace level to 4 (warning) will ensure that all trace output for the specific module 
will be included in that trace file.

The default tracing level for every module on the Cisco ASR 1000 Series Router is notice.

All trace levels are not user-configurable. Specifically, the alert, critical, and notice tracing levels cannot 
be set by users. If you wish to trace these messages, set the trace level to a higher level that will collect 
these messages.

Emergency

0

The message is regarding an issue that makes the system unusable.

Alert

1

The message is regarding an action that must be taken 
immediately.

Critical

2

The message is regarding a critical condition. This is the default 
setting for every module on the Cisco ASR 1000 Series Routers.

Error

3

The message is regarding a system error.

Warning

4

The message is regarding a system warning

Notice

5

The message is regarding a significant issue, but the router is still 
working normally.

Informational

6

The message is useful for informational purposes only.

Debug

7

The message provides debug-level output.

Verbose

8

All possible tracing messages are sent.

Noise

-

All possible trace messages for the module are logged.

The noise level is always equal to the highest possible tracing 
level. Even if a future enhancement to tracing introduces a higher 
tracing level, the noise level will become equal to the level of that 
new enhancement.
