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.
