Configuring NTP
You can configure a WX switch to use the Network Time Protocol (NTP)
to automatically set the system date and time. NTP polls network time
servers at regular intervals and synchronizes the system date and time
with the servers. By default, NTP is not enabled. You can specify up to
three NTP servers.

with the servers. By default, NTP is not enabled. You can specify up to
three NTP servers.
If NTP is configured on a system whose current time differs from the NTP
server time by more than 10 minutes, convergence of the WX time can
take many NTP update intervals. 3Com recommends that you set the time
manually to the NTP server time before enabling NTP to avoid a
significant delay in convergence.
