Understanding Terminal Parameters
Each system login, whether through the serial console or through telnet or ssh, creates a session.
The session is initialized with settings that are configurable from the line configuration sub-mode,
but most of them can also be changed from Exec mode while the session is active. Such changes
are not persistent, however, and are lost when the session is terminated.
The following table lists available settings and modes where each can be configured. Table 7 •

The system allows one serial console session and up to 16 network sessions. The console session
is called “console 0” whereas each network session is called “vty X” where vty is an abbreviation
for Virtual TTY and X is a value between 0 and 15.
The configuration appears near the bottom of running-config and looks like this:
line console 0
exec-timeout 0
!
line vty 0
!
line vty 1
!
line vty 2
! [...]
It is possible to specify different settings for each vty, but this is generally not recommended since
