PTP VLAN ID
•
This setting selects the value of the ID field in the 802.1Q VLAN tag in request messages issued by the relay’s peer
delay mechanism. It is provided in compliance with PP. As these messages have a destination address that indicates
they are not to be bridged, their VLAN ID serves no function, and so may be left at its default value.
•
Depending on the characteristics of the device to which the relay is directly linked, VLAN ID may have no effect.
•
This setting applies to all of the relay’s PTP capable ports.
b) SNTP PROTOCOL

PRODUCT SETUP
REAL TIME CLOCK
SNTP PROTOCOL
The L30 supports the Simple Network Time Protocol specified in RFC-2030. With SNTP, the L30 can obtain clock time over
an Ethernet network. The L30 acts as an SNTP client to receive time values from an SNTP/NTP server, usually a dedicated
product using a GPS receiver to provide an accurate time. Both unicast and broadcast SNTP are supported.
If SNTP functionality is enabled at the same time as IRIG-B, the IRIG-B signal provides the time value to the L30 clock for
as long as a valid signal is present. If the IRIG-B signal is removed, the time obtained from the SNTP server is used. If
either SNTP or IRIG-B is enabled, the L30 clock value cannot be changed using the front panel keypad.
To use SNTP,
SNTP SERVER IP ADDR
must be set to the SNTP/NTP server IP address. Once this address is set and
SNTP
FUNCTION
is “Enabled”, the L30 attempts to obtain time values from the SNTP/NTP server. Since many time values are
obtained and averaged, it generally takes three to four minutes until the L30 clock is closely synchronized with the SNTP/
NTP server. It may take up to two minutes for the L30 to signal an SNTP self-test error if the server is offline.
The UR-series relays do not support the broadcast, multicast or anycast SNTP functionality.
