Cancelling an outbound Telnet session

Examples of Syslog messages for CLI access
When a user whose access is authenticated by a local user account, a RADIUS server, or a TACACS
or TACACS+ server logs into or out of the CLI User EXEC or Privileged EXEC mode, the software
generates a Syslog message and trap containing the following information:
• The time stamp
• The user name
• Whether the user logged in or out
• The CLI level the user logged into or out of (User EXEC or Privileged EXEC level)
NOTE
Messages for accessing the User EXEC level apply only to access through Telnet. The device does
not authenticate initial access through serial connections but does authenticate serial access to the
Privileged EXEC level. Messages for accessing the Privileged EXEC level apply to access through the
serial connection or Telnet.
The following examples show login and logout messages for the User EXEC and Privileged EXEC
levels of the CLI.
device# show logging
Syslog logging: enabled (0 messages dropped, 0 flushes, 0 overruns)
Buffer logging: level ACDMEINW, 12 messages logged
level code: A=alert C=critical D=debugging M=emergency E=error
I=informational N=notification W=warning
Static Log Buffer:
Dec 15 19:04:14:A:Fan 1, fan on right connector, failed
Dynamic Log Buffer (50 entries):
Oct 15 18:01:11:info:dg logout from USER EXEC mode
Oct 15 17:59:22:info:dg logout from PRIVILEGE EXEC mode
Oct 15 17:38:07:info:dg login to PRIVILEGE EXEC mode
Oct 15 17:38:03:info:dg login to USER EXEC mode
Syntax: show logging
The first message (the one on the bottom) indicates that user "dg" logged in to the CLI User EXEC
level on October 15 at 5:38 PM and 3 seconds (Oct 15 17:38:03). The same user logged into the
Privileged EXEC level four seconds later.
The user remained in the Privileged EXEC mode until 5:59 PM and 22 seconds. (The user could have
used the CONFIG modes as well. Once you access the Privileged EXEC level, no further
authentication is required to access the CONFIG levels.) At 6:01 PM and 11 seconds, the user ended
the CLI session.
Removing user-login details from the Syslog messages and traps
If you want to disable the logging of user-login details from the system log, enter the following
commands.
device(config)# no logging enable user-login
device(config)# write memory
device(config)# end
device# reload
Cancelling an outbound Telnet session
If you want to cancel a Telnet session from the console to a remote Telnet server (for example, if the
connection is frozen), you can terminate the Telnet session by doing the following.
