Telnet Server
The following Telnet Server parameters can be set:
Telnet Server This option activates Telnet access to the
airFiberX radio.
• Server Port Specify the TCP/IP port of the Telnet Server.
NTP Client
Network Time Protocol (NTP) is a protocol for
synchronizing the clocks of computer systems over
packet-switched, variable-latency data networks. You can
use it to set the system time on the airFiberX radio. If the
Log option is enabled, then the system time is reported
next to every log entry that registers a system event.
NTP Client Enables the airFiberX radio to obtain the
system time from a time server on the Internet.
• NTP Server Specify the IP address or domain name of
the NTP server.
Dynamic DNS
Domain Name System (DNS) translates domain names
to IP addresses; Each DNS server on the Internet holds
these mappings in its respective DNS database. Dynamic
Domain Name System (DDNS) is a network service that
notifies the DNS server in real time of any changes in the
airFiberX radio’s IP settings. Even if the airFiberX radio’s IP
address changes, you can still access the airFiberX radio
through its domain name.
Dynamic DNS If enabled, the airFiberX radio allows
communications with the DDNS server.
• Host Name Enter the host name of the DDNS server.
• Username Enter the user name of the DDNS account.
• Password Enter the password of the DDNS account.
• Show Check the box to display the password
characters.
System Log
System Log This option enables the registration routine
of system log (syslog) messages. By default it is disabled.
• Remote Log Enables the syslog remote sending
function. System log messages are sent to a remote
server, which is specified in the Remote Log IP Address
and Remote Log Port fields.
- Remote Log IP Address The host IP address that
receives syslog messages. Properly configure the
remote host to receive syslog protocol messages.
- Remote Log Port The TCP/IP port that receives syslog
messages. 514 is the default port for the commonly
used system message logging utilities.
Every logged message contains at least a system time and
host name. Usually a specific service name that generates
the system event is also specified within the message.
Messages from different services have different contexts
and different levels of detail. Usually error, warning, or
informational system service messages are reported;
however, more detailed debug level messages can also
be reported. The more detailed the system messages
reported, the greater the volume of log messages
generated.
Device Discovery
Discovery Enables device discovery, so the airFiberX
radio can be discovered by other Ubiquiti devices through
the Discovery tool.
CDP Enables Cisco Discovery Protocol (CDP)
communications, so the airFiberX radio can send out CDP
packets to share its information.
