Chapter 12
Telnet Configuration and Capabilities
This chapter covers the Telnet Configuration and Capabilities of the Prestige.
12.1 About Telnet Configuration
Before the Prestige is properly setup for TCP/IP, the only option for configuring it is through the console
port. Once your Prestige is configured, you can use telnet to configure it remotely as shown below.
Figure 12-1 Telnet Configuration on a TCP/IP Network
12.2 Telnet Under NAT
When Network Address Translation (NAT) is enabled and an inside server is specified, telnet connections
from the outside will be forwarded to the inside server. So to configure the Prestige via telnet from the
outside, you must first telnet to the inside server, and then telnet from the server to the Prestige using its
inside LAN IP address. If no inside server is specified, telnetting to the NAT’s IP address will connect to
the Prestige directly.
12.3 Telnet Capabilities
12.3.1 Single Administrator
To prevent confusion and discrepancy on the configuration, your Prestige only allows one administrator to
log in at any time. Your Prestige also gives priority to the console port over telnet. If you have already
connected to your Prestige via telnet, you will be logged out if another user logs in to the Prestige via the
console port.
