New-ADReplicationSiteLink is accessible with the help of addsadministration module. To install addsadministration on your system please refer to this link.

Synopsis

Creates a new Active Directory site link for in managing replication.

Description

The New-ADReplicationSiteLink cmdlet can be used to create a new Active Directory site link. A site link connects two or more sites. Site links reflect the administrative policy for how sites are to be interconnected and the methods used to transfer replication traffic. You must connect sites with site links so that domain controllers at each site can replicate Active Directory changes.

    Default value                
    Accept pipeline input?       false

-PassThru <SwitchParameter>
    Returns the new or modified object. By default (i.e. if -PassThru is not specified), this cmdlet does not generate any output.

    Accept wildcard characters?  false

-ReplicationFrequencyInMinutes <Int32>
    Species the frequency (in minutes) for which replication will occur where this site link is in use between sites. Active Directory preserves bandwidth between sites by minimizing the frequency of replication and by allowing you to schedule the availability of site links for replication. By default, intersite replication across each site link occurs every 180 minutes (3 hours). You can adjust this frequency to match your specific needs. Be aware that increasing this frequency increases the amount of bandwidth used by replication.

    Required?                    false
    Position?                    named
    Default value                
    Accept pipeline input?       True (ByPropertyName)
    Accept wildcard characters?  false

-ReplicationSchedule <ActiveDirectorySchedule>
    Specifies the default replication schedule for any connections within this site link (intra-site replication). This allows you to schedule the availability of site links for use by replication. By default, a site link is available to carry replication traffic 24 hours a day, 7 days a week. You can limit this schedule to specific days of the week and times of day. You can, for example, schedule intersite replication so that it only occurs after normal business hours.

    Required?                    false
    Position?                    named

The service may be any of the following:  Active Directory Lightweight Domain Services, Active Directory Domain Services or Active Directory Snapshot instance.

    Required?                    false
    Position?                    named
    Default value
