Network Services parameters
Enable Network Management Protocol (SNMP)
Enables and disables remote management of the router using SNMP. This checkbox does not
actually directly control the SNMP functionality, but enables or disables the remaining SNMP
controls on this page.
Note Simply clicking on this checkbox may not be sufficient to allow this service to start
working. Depending upon the version selected below, additional configuration may be
required.
To perform detailed configuration, including setting up command filters, users and SNMP
traps, go to Configuration > Remote Management > SNMP.
Enable SNMP v1
When this checkbox is checked, the router uses SNMP version 1.
UDP Port n
The standard UDP port that is used by this service is 161 which is used as the default. If a
different port is required, enter the port number into the text entry box.
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 used to supply time data for the SNTP
server. The usual options are:
• Internal real time clock (RTC) device
• A GPS module (if supported)
• An NTP client (if supported).
Enable Secure Shell Server (SSH / SFTP)
The simplest way to check the status or configuration of the router or to upload new firmware
is to use the CLI over a directly connected ASY port or via a telnet session. Both of these
options have security implications. If a user wishes to gain access to the command line
interface of the router but using a more secure protocol, then selecting this checkbox will
enable a secure shell to start. This option also enables support for SFTP for secure file
transfers.
Enable Telnet Server
Selects between a simple telnet server or telnet over SSL. When this option is selected, the
simple, insecure version of telnet is enabled.
