User`s guide

The web page described here collects together a number of services that are provided by
the router into one section to enable the user to quickly enable or disable these services
without having to navigate to multiple sections of the menu. Detailed configuration is
performed within the specific section.
Enable Network Management Protocol (SNMP)
Click on this checkbox to enable and disable 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.
Detailed configuration, including setting up command filters, users and SNMP traps are to be
found at Configuration > Remote Management > SNMP
Enable SNMP v1
When this checkbox is checked, the router will use version 1 of the protocol.
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 this checkbox is checked, the router will use version 2c of the protocol.
Enable SNMP v3
When this checkbox is checked, the router will use version 3 of the protocol.
Enable Simple Network Timer Server (SNTP)
When checked, the router will act as an 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
This radio button selects between a simple telnet server or telnet over SSL. When this
option is selected, the simple, insecure version of telnet is enabled.
Enable Telnet over SSL
If security is an issue, then selecting this option with the radio button disables the simple
version and enables telnet over the secure socket layer (SSL) protocol.
Enable Web Server (HTTP)
Much of the configuration of the router may be performed using the web GUI as described
here. However, HTTP is an insecure protocol and so for security reasons, this service may
be disabled by deselecting this radio button and hence, enabling the following secure web
