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 various parameters set, including the TCP port number, timeouts, and a
password. These parameters can be configured via the web or CLI interface.
Command Attributes
• Telnet Status – Enables or disables Telnet access to the switch.
(Default: Enabled)
• Telnet Port Number – 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)
