Figure 8.2: Ports - Physical Ports - General Form
The General form allows you to define general port settings and select the connection type to a
serial port (SSH, Telnet or both).
The number of the selected port or ports displays next to the Done button at the bottom of the form
in the format: Selected ports #:N, where N stands for the port number.
Connection profiles
The following sections describe the available connection protocols for each connection to the
serial ports.
Console Access Server (CAS) profile connection protocols
When a serial port is connected to the console port on a device, a CAS profile must be defined for
the serial port.
Selecting the appropriate connection protocol on the Ports - Physical Ports - General is part of
defining the CAS profile.
The CAS connection protocols apply in the following cases:
• When a user accesses the serial port through the Web Manager, the session automatically uses
the specified protocol to connect to the console of the connected device.
• When a user logs in remotely to the serial port, access is allowed only for the selected protocol.
If another protocol is used then access is denied. For example, if you specify the Console
(SSH) protocol, the user can use SSH but cannot use Telnet to access the serial port.
