The polling interval range is from 4 to 16. Defaults Not configured. Command Modes CONFIGURATION Command History This guide is platform-specific. For command information about other platforms, see the relevant Dell EMC Networking OS Command Line Reference Guide. Version Description 9.14(0.0) 9.10(0.1) 9.10(0.0) 9.10(0.0) 9.8(2.0) 9.8(1.0) 9.8(0.0P5) 9.8(0.0P2) 9.7(0.0) 9.6(0.0) 9.4.(0.0) 9.2(1.0) 9.0.2.0 8.3.11.1 8.4.1.0 7.6.1.0 7.5.1.0 6.1.1.0 The trusted-key range value is increased from 1 to 65534.

Introduced on the Z9100-ON. Introduced on the S4048-ON. Introduced on the S3048-ON. Introduced on the S6000-ON. Added support for VRF. Added support for VRF. Introduced on the Z9500. Introduced on the S6000. Introduced on the Z9000. Added IPv6 support. Introduced on the S-Series. Introduced on the C-Series. Introduced on the E-Series. Usage Information You can configure multiple time-serving hosts. From these time-serving hosts, the Dell EMC Networking OS chooses one NTP host with which to synchronize. To determine which server is selected, use the show ntp associations command. Because many polls to NTP hosts can affect network performance, Dell EMC Networking recommends limiting the number of hosts configured. By default, the system performs a time synchronization if the time difference from the time source is greater than one second. When the Dell EMC Networking OS NTP client receives inconsistent timestamp in the origin timestamp filed, it logs the syslog message. It is due to the older versions of NTPD server implementation. Upgrade the system to the latest NTPD package in the NTP server and the system logs the following NTP syslog message: Dell EMC# May 30 13:27:46 %STKUNIT2-:CP %ntp-6-: receive: Unexpected origin timestamp 0xdeb95bee.06ba346e does not match aorg 0000000000.00000000 from [email protected] xmt 0xdeb95bee.30907a87 1712 System Time and Date

Usage

Information

You can configure multiple time-serving hosts. From these time-serving hosts, the Dell EMC Networking

OS chooses one NTP host with which to synchronize. To determine which server is selected, use the

show ntp associations

command.

Because many polls to NTP hosts can affect network performance, Dell EMC Networking recommends

limiting the number of hosts configured.

By default, the system performs a time synchronization if the time difference from the time source is

greater than one second.

When the Dell EMC Networking OS NTP client receives inconsistent timestamp in the origin timestamp

filed, it logs the syslog message. It is due to the older versions of NTPD server implementation. Upgrade

the system to the latest NTPD package in the NTP server and the system logs the following NTP syslog

message:

Dell EMC# May 30 13:27:46 %STKUNIT2-:CP %ntp-6-: receive: Unexpected

origin timestamp 0xdeb95bee.06ba346e does not match aorg

0000000000.00000000 from [email protected] xmt 0xdeb95bee.30907a87
