Checklist Ntp Configuration; The Ntp Setup Screen - Spectracom VelaSync 1232 User Manual

shareware NTP clients are available on the Internet. The software running on the PC
determines whether NTP or SNTP is used.
When the NTP service is enabled, VelaSync will "listen" for NTP request messages from
NTP clients on the network. When an NTP request packet is received, VelaSync will
send an NTP response time packet to the requesting client. Under typical conditions,
VelaSync can service several thousand NTP requests per second without MD5 authen-
tication enabled, and at a somewhat lower rate with MD5 authentication enabled.
You can either enable or completely disable the NTP Service. When NTP is disabled, no
NTP time packets will be sent out to the network. When enabled, by default, the NTP
Service operates in
2.10.1
