Synchronize SGM Time (asg_ntp_sync

Synchronize SGM Time (asg_ntp_sync_config)

Description

Use the asg_ntp_sync_config command to synchronize the time for all SGMs and the CMM with an NTP server.

Syntax

asg_ntp_sync_config set primary|secondary <ntp_ip|hostname> [-v <version>] 
[-r <timeout>]

asg_ntp_sync_config {disable|enable|delete}

asg_ntp_sync_config show

asg_ntp_sync_config -h

Parameter	Description
`set`	Configure an NTP server
`primary`	The system uses this NTP server by default
`secondary`	The system uses this if the primary NTP server is not available
`NTP Server <ip\|hostname>`	NTP server IP address or host name
`-v <version>`	Server version of the NTP Service (default = NTPv4)
`timeout`	Timeout in seconds between refreshes (default = 300 seconds).
`show`	Show NTP Server configuration
`disable`	Disable NTP service
`enable`	Enable NTP service
`delete`	Delete primary or secondary NTP Service
`-h`	Show syntax and help information

Notes:

This command runs ntpdate -u on each SGM and the CMM to synchronize to the local time,
If you define a refresh time that is less than the default (300 seconds), refresh occurs every 300 seconds.
To allow time synchronization for all SGMs, you must disable the replies_from_any_port property for the NTP over UDP service:
1. In GuiDBEdit, search for the NTP/UDP service.
2. Go to the replies_from_any_port property.
3. Change the property to false.
4. Install policy.

Validation

Run ‘show time’ on all SGMs and make sure that the time is the same.
Run tcpdump on port 123/UDP for the applicable interface to make sure that all SGMs initiate NTP connections.
