VTY Lines The switch has ten VTY (virtual teletypewriter) lines. Each line supports
one remote Telnet or SSH management session. The switch allocates the
lines, which are numbered 0 to 9, in ascending order, beginning with line 0,
as remote sessions are initiated.
The VTY lines cannot be reserved for particular remote workstations
because the switch allocates them as needed. Line 0 is assigned by the
switch to a new remote session if there are no other active remote
sessions. Or, if there is already one active management session, a new
session is assigned line 1, and so on.
You can adjust these three parameters on the individual lines:
 Management session timer - This timer is used by the switch to
end inactive management sessions, automatically. This protects
the switch from unauthorized changes to its configuration sessions
should you leave your workstation unattended during a
management session. For instructions on how to set this timer,
refer to “Configuring the Management Session Timers” on
page 136.
 Number of SHOW command scroll lines - You can specify the
number of lines that SHOW commands display at one time on your
screen. Refer to “LENGTH” on page 106 to set this parameter.
 Remote authentication of management accounts - You can toggle
on or off remote authentication of management accounts on the
individual VTY lines. Lines use local authentication when remote
authentication is turned off. For background information, refer to
Chapter 96, “RADIUS and TACACS+ Clients” on page 1479.
