3.1.2.3. NTP Server
The settings for the time server are located under Administration > System Time > NTP Server. In this case, the
TK800 can work as a time server for the connected devices.
Via Master the stratum can be specified. This indicates how precise the server is. Values between 2 and 15 can be
specified. The lower, the closer the router is to an atomic or radio clock (from a topological point of view).
The Source Interface specifies the interface at which the devices can request the NTP service of the router. Alter‑
natively, a Source IP can be determined via which the NTP service is provided.
It is important that NTP server and NTP client work independently of each other, this also means that for both NTP
client and NTP server an NTP service from the Internet must be entered. For this purpose the address of the NTP
service is entered under Server Address. It is possible to enter more than one service.
3.1.3 3.1.3. Management Services
Under Administration > Management Services the access to the web interface with HTTP and HTTPS as well as to
the Command Line Interface (CLI) via Telnet and SSH can be configured.
HTTP
HTTP is the abbreviation for Hypertext Transfer Protocol and is used to access the router’s web interface.
HTTPS
HTTPS is the abbreviation for Hypertext Transfer Protocol Secure and uses SSL (Security Socket Layer) for en‑
crypted transmission of HTTP.
TELNET
TELNET is used to access the Command Line Interface (CLI) of the router.
