VOSS: console messages in current SSH session

M_Nees — Wed, 13 Jun 2018 01:23:00 GMT

In some troubleshooting cases i need log / console messages in current SSH CLI session.

In EXOS i can use "enable log target session" to redirect console log messages to current SSH session.
I am sure this is also possible in recent VSP 7200 VOSS (6.1.x).

Can you provide an example of a message that is getting logged to the console that is not also showing up in the log (show log file tail)?

Hi Joseph,

i am connected to Serial console and i get this kind of status messages:

in some cases - if i have only a ssh session (and no serial console - because i am remote connected) i want to redirect this kind of messages to the local ssh session.
Currently i have to check "show logging file tail" every seconds if i expect some change.

The searched functionality is more elegant because the occured message are pop up / injected into my ssh session.

Regards,Matthias

Hi all,

i get an advice.

"conf t"
"logging screen enable"This should redirect log messages to ssh session (i does not test yet).

Hi M.Nees,
yes,

you can see logging in real time on your screen by using 'logging screen enable' when you use telnet and ssh session.
