FIELD
DESCRIPTION
Enter the time service protocol that your time server sends when you turn on the
Prestige. Not all time servers support all protocols, so you may have to check with
your ISP/network administrator or use trial and error to find a protocol that works.
The main differences between them are the format.
Daytime (RFC 867)
format is day/month/year/time zone of the server.
Time (RFC-868)
format displays a 4-byte integer giving the total number of
seconds since 1970/1/1 at 0:0:0.
NTP (RFC-1305)
is similar to
Time (RFC-868)
.
Use Time Server

Prestige, the time and date will be reset to 2000-1-1 0:0:0.
Time Server IP

Chapter 19
Remote Management
This chapter covers remote management (SMT menu 24.11).
19.1 Introduction
You may restrict a service that can be used to remotely manage the Prestige using SMT menu 11 and
submenus.
19.1.1 Telnet
First configure your Prestige for remote management through an SMT session using the console port. Once
your Prestige is configured, you can configure it remotely using Telnet as shown next.
Figure 19-1 Telnet Configuration on a TCP/IP Network
19.1.2 FTP
You can upload and download Prestige firmware and configuration files using FTP. To use this feature,
your computer must have an FTP client.

Remote Management
19.1.3 Web
You can use the Prestige’s embedded web configurator for configuration and file management. See the
online help
for details.
19.1.4 SNMP (Simple Network Management Protocol)
Simple Network Management Protocol is a member of TCP/IP protocol suite that is used for exchanging
management information between network devices. Your Prestige supports SNMP agent functionality,
which allows a manager station to manage and monitor the Prestige through the network.
19.1.5 DNS (Domain Name System)
DNS links names to IP addresses. When you access Web sites on the Internet, you can type the IP address
of the site or the DNS name.
DNS servers on the Internet convert domain names to IP addresses. Your own Internet service provider
may do this conversion or connect to a specific DNS server that does. When you type a domain name in a
Web browser, a query is sent to the primary DNS server defined in your Web browser’s configuration
dialog box. The DNS server converts the name you specified to an IP address and returns this address to
your system. From then on, the IP address is used in all subsequent communications.
DNS service port number (53) is not configurable on the Prestige.
19.2 Remote Management Setup
Remote management setup allows you to choose who can use what services on which interface to manage
the Prestige. You can customize the service port, access interface, and the secured client IP address to
enhance security and flexibility.
You may manage your Prestige from a remote location, via the Internet (
WAN only
), via the
LAN only
,
Both
(LAN & WAN) or neither (
Disable
).
