To change the time, use the "
sys rdate
" or "
sys date
" commands.
To return NTP to the default state, use the "
default ntp
" command from the main configuration
context.
fiberdriver(config)# default ntp
fiberdriver(config)#
9.4. Displaying NTP Status
After some NTP server hosts are set and NTP is enabled, use the "
show ntp
" command from the main
configuration context to display the NTP settings.
fiberdriver(config)# show ntp
NTP configuration:
Enable: yes
NTP servers:
ntp-server host 192.168.14.98
ntp-server host 192.168.14.106
ntp-server host 10.1.1.8

9.5. NTP with "sys rdate" and "sys date"
If the system time is not synchronized with the configured NTP servers, NTP attempts to drift the system
time back to the proper time with incremental changes. The further the time is away from the NTP time,
the longer the correction will take.
If NTP sees a time offset of more than 1000 seconds (about 17 minutes), it will not drift. The user must
manually force the clock within 1000 seconds of the NTP time using commands like "
sys rdate
" or
"
sys date
".
When NTP first starts up, it tries once to set the time to the NTP time even if the offset is beyond 1000
seconds. Disable and re-enable NTP to force an NTP time synchronization.
fiberdriver(config)# no ntp
fiberdriver(config)# ntp
fiberdriver(config)#
At least one NTP server must be configured and reachable for NTP to reset successfully and synchronize
the EM316LNXNM clock.
