Edit Site Overview
Tenant Administrator users can edit the parameters configured for a branch site or an enterprise hub site with the following site status:
To edit a provisioned or a partially-provisioned provider hub site, the Operational Status of the site must be UP.
Tenant Administrators can only edit the parameters of provider hub sites that they added.
You can add or delete WAN links, or modify the site parameters without affecting the connectivity to Contrail Service Orchestration (CSO).
For more information about how you can edit branch sites and enterprise hub sites parameters, see Edit Branch and Enterprise Hub Site Parameters.
You cannot edit cloud spoke sites.
You can modify:
Site properties: Address and Contact Information, Timezone, and so on.
Network topology by:
Adding or deleting a WAN link
Modifying the properties of existing WAN links
Modifying the dynamic VPN (DVPN) thresholds of a site
Adding or deleting mesh tags on spoke sites or enterprise hub sites
What happens after you add a WAN link?
When you add WAN links to a branch site or enterprise hub site:
Secure Operations, Administration, and Maintenance (OAM) tunnels are added between the spoke and hub sites if the Use for OAM Traffic option is enabled.
Data links to provider hubs are established based on the overlay tunnel parameters configured for the WAN links.
Data links to enterprise hubs are established based on the mesh tags configured on the spoke and enterprise hub sites.
Monitoring of the new WAN link is enabled.
What happens to the existing DVPN and static tunnels when you modify the site parameters?
When you modify the DVPN thresholds configured for a WAN link, the changes you made do not reflect immediately. After the threshold for deleting tunnels is reached, the existing DVPN tunnels are deleted and new DVPN tunnels are added based on the modified DVPN parameters. If you want to see the changes you made immediately, manually delete the DVPN tunnels and add them again. For more information, see Adding On-Demand Mesh Tunnels and Deleting On-Demand Mesh Tunnels.
When you modify the mesh tags for a WAN link, the changes you made do not automatically reflect in the static tunnels (existing between the spoke and an enterprise hub site, or between two enterprise hub sites) as this can cause data connectivity loss. To delete the existing static tunnels and add static new tunnels based on your modified parameters, you must reconfigure the static tunnels to apply the changes to the existing WAN link. To reconfigure the static tunnels, select Reconfigure (Resources > Site Management> Site Name> WAN tab) in Customer Portal. For more information, see Reconfigure Static Tunnels.
What happens after you delete a WAN link?
When you delete a WAN link from a site, all the associated tunnels (secure OAM, data links to hub sites, and DVPN tunnels) are also deleted.
Before deleting WAN links on:
Spoke devices, ensure that at least one OAM WAN link is present is enabled for the site.
NFX 250 dual CPE devices, ensure that atleast one OAM WAN link is present on both the CPE devices.
Enterprise hubs, ensure that there are no static tunnels connected between the spoke sites and the enterprise hub using the WAN link.
What should you do if adding or deleting a WAN link fails?
If the addition or deletion of a WAN link fails, PARTIALLY DEPLOYED is displayed next to the WAN link name.
You can do one of the following:
Retry the specific edit site job to execute the failed tasks from the Jobs page (Monitor > Jobs). For more information, see Retrying a Failed Job on Devices.
Redeploy the WAN link by clicking the Re-Deploy WAN Link toggle button and updating the WAN link parameters, which first deletes the WAN link and then adds it again.
Redeploying a partially deployed WAN link can take several minutes based on the number of sites connected in a network.
Leave the WAN link as is and redeploy the WAN link later.
Benefits of Editing Site Parameters
Improves the user experience by enabling reconfiguration of the site by simply editing the site parameters without having to delete and add the site back.
Simplifies the onboarding of a site. Initially, you can onboard a site by enabling only one OAM WAN link. You can later modify the site parameters to configure the site as per your business needs.
