How to sync the config in CLI when we have multiple traffic-group ( Active-Active)

Whichever is the group with the disalignment .. "show /cm sync-status" command should help you clarify this, but I'd guess your main Device Group will be the sync-failover one.

The others you see are likely the default BIGIP device groups, device_trust_group is a sinc-only auto-sync group which is created when you perform device trust for the first time and handles device trust, while you might also see datasync-global-dg if you have WAF provisioned, this is a sync-only manual-sync group that handles metadata and attack signature update sync between the two units. It's unlikely to see those groups out of sync in daily administration and you will have some high-priority problems to be handled if they are.

You're confusing Traffic and Device Groups.

Config Sync is commanded by Device Groups, not Traffic Groups, so an Active/Active scenario doesn't necessarily mean there will be separate Config Sync.

You can have multiple Device Groups for config sync, either with separate devices (in a 2+ unit HA environment) or for separate modules (eg. set WAF to automatic sync ), but if you only have one device group for your HA units, the will also be only one configsync option available.

Command will be (v11 to v16)

run /cm config-sync <sync_direction> <sync_group> 

Where <sync_group> is your Device Group name (not traffic group!) and <sync_direction> will either be to-group or from-group depending on which unit will receive/push the configuration.
