ARP and Route Configuration 
To facilitate network connectivity on the management and GBE interfaces, the RF 
Gateway 1 can create static Route and ARP entries.  Static routes provide network 
connectivity to devices that are not on the network.  For example, a static route could 
be required to support multicast sessions on the GbE interface from a device on 
another network.  Static ARPs are provided to allow connectivity to devices that are 
not responding to ARP requests. Depending on network configuration and 
requirements, static ARPs or routes may be required on any of the management or 
GbE interfaces.   
To Configure ARP And Route Entries 
1 Navigate to the System/ARP & Routes page. 
Result: The ARP & Routes window is displayed. 
 
2 Enter the appropriate parameters on the web interface. 
3 Click Add.   
						

							 
 
 Clock Configuration 
 
78-4025112-01 Rev H0 49 
 
Clock Configuration 
The RF Gateway 1 provides several different configuration options for obtaining and 
maintaining accurate time on the system.  These options include time 
synchronization from a network time server and obtaining time from an on-board 
real-time clock (RTC).  
Real -Time Clock Setup 
The RF Gateway 1 has an on-board, real-time clock (RTC) with battery back-up 
which can be used to provide system time. The RTC can be set manually via the web 
interface or configured to be updated with network time obtained from an SNTP 
server.  The Synchronize With Server  parameter is used to control the RTC 
synchronization behavior.  When set to Disabled, the RF Gateway 1 obtains system 
time from the RTC at startup.  Once set, the internal system clock runs 
independently until the RTC is changed. The Clock Configuration page provides the 
following user-configurable options. 
 Current Time 
 New Time  
 Synchronize with Server 
To Set the Real Time Clock: 
1 Navigate to the System/Clock page. 
Result: The Clock Configuration page is displayed. 
 
2 In the New Time field, enter year, date and current time. 
Example: 2008/06/17/0052:26 
3 Click Apply.

4 Click OK. 
Result: The time is displayed in the Current Time window.  
Simple Network Time Protocol (SNTP) 
When Synchronize With Server is set to Enabled, the RF Gateway 1 periodically 
attempts to obtain network time from one of the SNTP servers specified by the IP 
address on the Clock Configuration page.  If communication with the SNTP server is 
successful, the RTC and internal system clock are updated.  If communication with 
both SNTP servers fails the internal system clock updates with a value obtained from 
the RTC.  For the remainder of the synchronization interval, the system runs on its 
own time independent of the RTC and network server.  At the start of the next 
synchronization interval, the system attempts to resynchronize with the network 
time server and set its clocks accordingly.   
To Set the SNTP server for RTC 
1 Navigate to the System/Clock page. 
Result: The Clock Configuration page is displayed. 
 
2 Set Synchronize with Server to Enabled. 
3 In the Main SNTP Server IP Address field, enter the IP address in xx.xx.xx.xx 
format. TP582

format. 
5 In the SNTP Mode field, select Unicast (Multicast is not supported). 
6 In the Time Zone field, select the correct time zone depending on current location. 
7 The Synchronization Interval parameter specifies the interval at which the RF 
Gateway 1 resynchronizes the system clock and RTC to the network time. Set the 
SNTP Synchronization rate in minutes. The default is 1440 minutes or 24 hours. 
8 The Synchronization Timeout parameter specifies how long the RF Gateway waits 
for the network time server to respond. Set the timeout in seconds. 
9 Click Apply.  
10 Click Synchronize Now to force a network synchronization. This sets the 
systems time and RTC. 
11 Click Save. 
Result: On the next system reboot, the system time is displayed in periodic 
intervals based on the Synchronization Interval setting.
