disabling syslog output to the console

omera

Hey Everyone,

I have an issue with the syslog messages being sent to the console every time I do a debug and enable #terminal monitor. I have the logs sent to a remote server but I don't want them to impact the console output while debugging. Is there any way to disable syslog messages from going to the console output.

You send log to syslog server without see it in console I think

Only disable terminal monitor and keep enable log to host (server)

Try this

Sorry if I didn't explain myself very well. The Syslog logs indeed do not show up if I don't do #terminal monitor, but sometimes I have to do a debug session on the router, with that enabling #terminal monitor would push all of the syslogs to my output hindering the debug useless.

share the config if you can please

the command didn't work 

#no logging console

as soon as I execute #terminal monitor, all of the syslog messages outputs to the tty.

No logging sync 

Then 

Logging sync 

And check again.

didn't work, Syslog messages are still outputting to tty. 

 

I now review the info. You share 

Thanks

Hey @MHM Cisco World , do you mean the IP where I SSH to the router (router IP)? 

Hi friend 
config the console level below 7 (debug)
this make you run console and dont see debug and in same time the debug send to syslog server.
try this way.
thanks

command should be in config mode

config t

no logging console

exit

 

Console logging: level debugging,   <-- this will lock you console when you enable debug

suggested config is

config t 

logging console inform

end

@balaji.bandi and @MHM Cisco World appreciate the tremendous help. What I am actually trying to do is not disabling the debug messages from popping into the console. I want to stop all syslog messages from showing in the tty while I am doing a debug. Say for example I am doing a #crypto debug, I don't want the syslog messages and the crypto debug messages to scramble together when I execute #terminal monitor, I just want to see the debug messages.

but as I mention before if you want to enter debug and not make debug show in console use 
 

NO logging synchronous  

 under the console line Or VTY (if you use telnet or ssh)

if you want other log message to appear and only debug not appear then as I mention before adjust the log level
