Telnet Server

The following Telnet Server parameters can be set:

Telnet Server

This option activates Telnet access to the

AF-5X.

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 AF-5X. 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 AF-5X 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
AF-5X’s IP settings. Even if the AF-5X’s IP address changes,
you can still access the AF-5X through its domain name.

Dynamic DNS

If enabled, the AF-5X 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 AF-5X can

be discovered by other Ubiquiti devices through the
Discovery tool.

CDP

Enables Cisco Discovery Protocol (CDP)

communications, so the AF-5X can send out CDP packets
to share its information.
