Tracing and Trace Management
3
Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide
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.
When setting trace levels, it is also important to remember that the setting is not done in a configuration
mode, so trace level settings are returned to their defaults after every router reload.
Caution
Setting tracing of a module to the debug level or higher can have a negative performance impact. Setting
tracing to this level or higher should be done with discretion.
Caution
Setting a large number of modules to high tracing levels can severely degrade performance. If a high
level of tracing is needed in a specific context, it is almost always preferable to set a single module on a
higher tracing level rather than setting multiple modules to high tracing levels.
Viewing a Tracing Level
By default, all modules on the Cisco ASR 1000 Series Routers are set to notice. This setting will be
maintained unless changed by a user.
To see the tracing level for any module on the Cisco ASR 1000 Series Routers, enter the
show platform
software trace level
command in privileged EXEC or diagnostic mode.
In the following example, the
show platform software trace level
command is used to view the tracing
levels of the Forwarding Manager processes on the active RP:
Router#
show platform software trace level forwarding-manager rp active
