Method used to apply the automatic synchronization between NE time and NMS time

5

After the automatic synchronization between NE time and NMS time is enabled, the NE time and NMS time will be synchronized automatically based on the specified period.

On the U2000, perform the following procedure:

1. In the NE Explorer, choose Configuration > NE Batch Configuration > NE Time Synchronization from the navigation tree. In the Operation Result dialog box, click Close.

2. Select NMS as the synchronization mode and click Apply.

3. Set the Start Time and Period (days), and then click Apply. In the Auto-Synchronization Settings dialog box that is displayed, click Yes.

Note: The Start Time must be set to a time later than the current time.

5. In the Operation Result dialog box, click Close.

Synchronization modes between NMS time and NE time on WDM products
Synchronization modes between NMS time and NE time: With the time synchronization function, the NE time is kept consistent with the NMS time. This allows the NMS to record the correct time at which alarms occur and the correct time at which abnormal events are reported by NEs. When NEs report alarms and abnormal events to the NMS, the NMS records the time of alarms and events based on the NE time. If the NE time is incorrect, the generation time of alarms recorded on the NMS is also incorrect, which may cause troubles in fault locating. The same case happens to the generation time of abnormal events that are recorded in the NE security log. To ensure the accuracy of NE time, the NMS provides two time synchronization modes with the following servers: the NMS server and the standard NTP server. Note: The Web LCT improves the accuracy of NE time by synchronizing the NE time with the NMS time. If synchronization with the NMS server is applied, all NEs use the NMS server time as the standard time, and can be synchronized with the NMS server manually or automatically. The NMS time refers to the time of the workstation where the NMS server resides or system time of the NMS server. This synchronization mode is easy and applies to a network with relatively low requirement on time accuracy. If synchronization with the standard NTP server is applied, all NEs and the NMS are synchronized with the standard NTP server automatically. The standard NTP server can be the NMS server or a dedicated time server. This synchronization mode makes the NE time and NMS time accurate to 1/1000,000,000 seconds and applies to a network that has a high requirement on time accuracy.

Method used to synchronize the time between an NE and the standard NTP server.
The standard NTP service can automatically synchronize the NE time with the standard NTP server time.

Method used to synchronize time for storage
Method used to synchronize time for storage: 1. Locating procedure: The time for alarms in the storage system is different from that of I2000 or local time. 2. Solution: Time synchronization Log in to the storage's OSM management page, and choose System > System Information > Synchronize System Time. Note: If clock jumping patches have been installed, synchronization on the page cannot be performed. In this chase, you need to modify the time manually following instructions provided in the patch guide.

Time and time zone policy of the server BMC
The default time zone of iMana/iBMC is the GMT time zone. The time zone and time synchronization policy is as follows: iMana and iBMC of rack servers synchronize time with the BIOS every minute but does not synchronize the time zone. Therefore, if the iMana/iBMC time is different from the OS time, the difference is caused by different time zone settings. iMana/iBMC of blade servers (E9000 and E6000) synchronize time with the management module every hour. The management module supports NTP settings for time synchronization.

Is the AD synchronization a real-time synchronization?
No. The AD server synchronizes data at an interval.
