Pre-requisites
To congure a secure connection from the switch to the syslog server:
1 On the switch, enable the SSH server
DellEMC(conf)#ip ssh server enable
2 On the syslog server, create a reverse SSH tunnel from the syslog server to the Dell OS switch, using following syntax:
ssh -R <remote port>:<syslog server>:<syslog server listen port> user@remote_host -nNf
In the following example the syslog server IP address is 10.156.166.48 and the listening port is 5141. The switch IP address is
10.16.131.141 and the listening port is 5140
ssh -R 5140:10.156.166.48:5141 admin@10.16.131.141 -nNf
3 Congure logging to a local host. locahost is “127.0.0.1” or “::1”.
If you do not, the system displays an error when you attempt to enable role-based only AAA authorization.
DellEMC(conf)# logging localhost tcp port
DellEMC(conf)#logging 127.0.0.1 tcp 5140
Log Messages in the Internal Buer
All error messages, except those beginning with %BOOTUP (Message), are log in the internal buer.
For example, %BOOTUP:RPM0:CP %PORTPIPE-INIT-SUCCESS: Portpipe 0 enabled
Conguration Task List for System Log Management
There are two conguration tasks for system log management:
• Disable System Logging
• Send System Messages to a Syslog Server
Disabling System Logging
By default, logging is enabled and log messages are sent to the logging buer, all terminal lines, the console, and the syslog servers.
