Enable Realport
When enabled, the router uses RealPort, patented RealPort COM/TTY port redirection
software for Microsoft Windows.
Enable Encrypted Realport
When enabled, the router uses RealPort software with encryption. Encrypted RealPort
offers a secure Ethernet connection between the COM or TTY port and a device server or
terminal server. Encryption prevents internal and external snooping of data across the
network by encapsulating the TCP/IP packets in a Secure Sockets Layer (SSL) connection and
encrypting the data using Advanced Encryption Standard (AES).
Enable Network Management Protocol (SNMP)
Enables and disables remote management of the router using SNMP. This setting does not
actually directly control the SNMP functionality, but enables or disables the remaining SNMP
controls on this page. To perform detailed configuration, including setting up command filters,
users and SNMP traps, go to Configuration > Remote Management > SNMP.
Note Simply clicking on this setting may not be sufficient to allow this service to start working.
Depending upon the SNMP version selected below, additional configuration may be required.
UDP Port n
The standard UDP port for SNMP is 161, the default. If you require a different port, enter the
port number into the text entry box.
Enable SNMP v1
When enabled, the router uses SNMP version 1.
Enable SNMP v2c
When enabled, the router uses SNMP version 2c.
Enable SNMP v3
When enabled, the router uses SNMP version 3.
Enable Simple Network Timer Server (SNTP)
When enabled, the router acts as a Simple Network Time Protocol (SNTP) time server.
Source
This drop-down selection menu selects the source that supplies time data for the SNTP server.
The usual options are:
n Internal real time clock (RTC) device
n A GPS module (if supported)
n An NTP client (if supported)
