SNTP Client
Key
Value
Feature Definition
SntpAddress 216.239.35.4
SNTP Cli-
ent
Ethernet IPV4 address of a SNTP server as a string. This record is not a member of
the default file, and therefore, the feature is disabled. If you wish to use this feature,
you must add this record to the setup file.
SNTP Address
The RMA PLUS implements a Simple Network Time Protocol (SNTP) client. If the configuration key SntpAddress is
present, the RMA PLUS will attempt to synchronize its time with the configured SNTP server once per day. If the con-
nection fails, the RMA PLUS will try again at a faster interval until the connection is successful.
Wireshark
Wireshark is an Ethernet network analyzer. If you are trying to diagnose an Ethernet issue, Wireshark is an invaluable
tool. The factory may ask for a network capture to help diagnose problems.
If the problem is between PC software and the RMA PLUS, you can install Wireshark on the PC with no additional con-
figuration. If the problem is between a device without Wireshark and the RMA PLUS, you can activate the port mirroring
feature of the embedded switch to obtain a network capture.
