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.

 

 

Syslog server

Logging messages are sent to a Syslog server as ASCII text. Up to

 

three Syslog servers can be defined for a stack.

 

 

The system logging configuration for the “session” sink is not saved to NVRAM. The configuration only affects the active session from which the commands are executed. Each session must be configured separately.
