This procedure assumes that the selected serial port is physically connected to a console port on
a device.
1. Go to Ports - Physical Ports in Expert mode, select a port or ports to modify, click the
appropriate Modify Ports button. The General form appears.
2. Click the General tab. The General form appears with the number(s) of the selected port(s)
next to the Done button at the bottom of the form. All active tabs are yellow.
3. To change the connection protocol, select one of the options from the Connection Protocol
pull-down menu: Console (Telnet), Console (SSH), Console (Telnet & SSH) or Console
(Raw). The default is Console (Telnet).
SSHv2 Dedicates a server terminal connected to the selected serial port to access a server
using the SSHv2 protocol. When the attached terminal is powered on, the console server
opens a SSHv2 session on the server. The server’s IP address should be specified on
the Other form, Ports - Physical Ports - Other.
Local Terminal Dedicates a server terminal connected to the selected serial port for connecting to the
console server. When the attached terminal is powered on, the console server opens a
Telnet session on itself. The user then can use any of the console server’s Linux
commands. You can also create a terminal profile menu, Applications - Terminal Profile
Menu that enables the user to quickly launch sessions on any number of remote hosts.
Raw Socket Dedicates a server terminal connected to the selected serial port to access a specific
remote host using the Raw Socket protocol. When the attached terminal is powered on,
the console server opens a Raw Socket session on the host using an IP address and
TCP port number specified on the Other form, Ports - Physical Ports - Other.
