Licensing Requirements and Limitations for NTP
Involved Network Elements
Other network elements are required to support NTP.
Licensing Requirements
NTP is a basic feature of a switch and is not under license control.
Feature Support in V200R019C10
All models of S2720, S5700, and S6700 series switches support NTP.
Feature Limitations
The existing configuration will not be deleted when the NTP service is disabled.
If the device does not support Real-Time Clock (RTC), it is recommended that you configure NTP to ensure time accuracy in logs. The following models do not support RTC:
S2720-EI, S2750-EI, S5700-10P-LI-AC, S5700-10P-PWR-LI-AC, S5700-28P-LI-BAT, S5700-28P-LI-24S-BAT, S5720-LI, S5720S-LI, S5735-L, S5735S-L, S5735S-L-M, S5720I-6X-PWH-SI-AC, S5720I-10X-PWH-SI-AC, S5720I-12X-SI-AC, S5720I-12X-PWH-SI-DC, S5735-S-I
- If the switch does not support RTC, manually set the device time. If the switch is powered off and restarts, the device time will become inaccurate. You need to manually set the device time again.
