Accessing the CLI
Using the local serial port
Any SMC serial port provides direct local access for managing the SMC. For
details on attaching a console terminal to the serial port and establishing a
connection, see “Hardware installation” on
page 59 .
After the connection is initiated, you are prompted to log on and enter a valid
password. For more information about different access levels and initial
passwords, see “Users and passwords” on
page 162 . When the login is
validated, the Main Menu of the CLI appears.
Using remote access
Using Telnet
Using a Telnet connection, you can manage the SMC from any workstation
connected to the network. Telnet access provides the same management
options as those available through the local serial port.
By default, Telnet access is disabled and all remote access is restricted.
Depending on the severity of the security policy, you may enable Telnet and
permit remote access to one or more trusted client stations. See “Defining the
remote access list” on
page 89 .
Note: Telnet is not a secure protocol. All data, including the password,
between a Telnet client and the SMC is unencrypted and
unauthenticated. If secure remote access is required, consider using
Secure Shell (SSH). See “Using Secure Shell (SSH)” on
page 185 .
Enabling Telnet access
For security purposes, Telnet is initially disabled. Before Telnet access is
possible, you must first perform some configuration using the serial port.
