ETTINGS
Use the System > Telnet menu to configure parameters for accessing the
CLI over a Telnet connection. You can access the onboard configuration
program over the network using Telnet (i.e., a virtual terminal).
Management access via Telnet can be enabled/disabled and other
parameters set, including the TCP port number, time outs, and a password.
Note that the password is only configurable through the CLI.) These
parameters can be configured via the web or CLI interface.

The following parameters are displayed in the web interface:
◆
Telnet Status – Enables or disables Telnet access to the switch.
(Default: Enabled)
◆
TCP Port – Sets the TCP port number for Telnet on the switch.
(Default: 23)
◆
Login Timeout – Sets the interval that the system waits for a user to
log into the CLI. If a login attempt is not detected within the timeout
interval, the connection is terminated for the session.
(Range: 0-300 seconds; Default: 300 seconds)
◆
Exec Timeout – Sets the interval that the system waits until user input
is detected. If user input is not detected within the timeout interval, the
current session is terminated. (Range: 0-65535 seconds; Default: 600
seconds)
◆
Password Threshold – Sets the password intrusion threshold, which
limits the number of failed logon attempts. When the logon attempt
threshold is reached, the system interface becomes silent for a
specified amount of time (set by the Silent Time parameter) before
allowing the next logon attempt. (Range: 0-120; Default: 3 attempts)
◆
Quiet Period – Sets the amount of time the management console is
inaccessible after the number of unsuccessful logon attempts has been
exceeded. (Range: 0-65535 seconds; Default: Disabled)
