Set-ADReplicationSiteLink

powershell

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

Synopsis

Sets the properties for an Active Directory site link.

Description

The Set-ADReplicationSiteLink cmdlet can be used to set properties on an 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.

Parameters 

-Add 
         Specifies values to add to an object property. Use this parameter to add one or more values to a property that cannot be modified using a cmdlet parameter. To modify an object property, you must use the LDAP display name. You can specify multiple values to a property by specifying a comma-separated list of values and more than one property by separating them using a semicolon.. The format for this parameter is

-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 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
    Default value

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

    Position?                    named
    Default value                
    Accept pipeline input?       false
    Accept wildcard characters?  false

-SitesIncluded <Hashtable>
    Specifies the list of sites included in the site link. For Set-ADReplicationSiteLink operations, you can add or include new sites within an existing site link by specifying them using this parameter. You do not have to specify all previously listed sites already within this link.

    Required?                    false
    Position?                    named
