Configuring Telnet Settings
– 95 –
Configuring Telnet Settings
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.
Parameters
The following parameters are displayed:
◆ Telnet Status – Enables or disables Telnet access to the switch.
(Default: Enabled)
◆ TCP Port – Sets the TCP port number for Telnet on the switch. (Range: 1-65535;
Default: 23)
◆ Max Sessions – Sets the maximum number of Telnet sessions that can
simultaneously connect to this system. (Range: 0-8; Default: 8)
A maximum of eight sessions can be concurrently opened for Telnet and
Secure Shell (i.e., both Telnet and SSH share a maximum number of eight
sessions).
◆ 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: 10-300 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: 60-65535 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:1-120;Default:3attempts)
◆ Silent Time – Sets the amount of time the management interface is
inaccessible after the number of unsuccessful logon attempts has been
exceeded. (Range: 1-65535 seconds; Default: Disabled)
Note:
The password for the Telnet connection can only be configured through the
CLI (see the “password” command in the CLI Reference Guide).
Note:
Password checking can be enabled or disabled for login to the console
connection (see the “login” command in the CLI Reference Guide). You can select
