Sinks
System logging messages can be sent via a number of ’sinks’ or methods. By default, none of the sinks is enabled. The following table provides a list of available sinks.

|
Session | Logging messages are sent to the current console or a Telnet or |
(Console/ | SSH session in |
Telnet/SSH) |
|
|
|
Log File | Logging messages are saved to a log file in the NVRAM of the |
| master module in the stack. NVRAM initialization and device |
| reset do not erase the log file. |
