Create a peering relationship

Contributors

POST /cluster/peers

Creates a peering relationship and, optionally, the IP interfaces it will use. There are two ways to create a peering relationship.

Provide remote IP

Here the user provides the remote IP address. Creating a new cluster peer relationship with a specific remote cluster requires at least one remote intercluster IP address from that cluster.

Required properties

  • remote.ip_addresses - Addresses of the remote peers. The local peer must be able to reach and connect to these addresses for the request to succeed in creating a peer.

  • Either set generate_passphrase to true or provide a passphrase in the body of the request; only one of them is required.

Optional properties

The following fields are optional for a POST on /cluster/peer/. All fields must follow the structure in the cluster peer API definition.

  • name - Name of the peering relationship.

  • passphrase - User generated passphrase for use in authentication.

  • generate_passphrase (true/false) - When this option is true, ONTAP automatically generates a passphrase to authenticate cluster peers.

  • ipspace - IPspace of the local intercluster LIFs. Assumes Default IPspace if not provided.

  • initial_allowed_svms - the local SVMs allowed to peer with the peer cluster's SVMs. This list can be modified until the remote cluster accepts this cluster peering relationship.

  • local_network - fields to create a local intercluster LIF. See section on "Creating local intercluster lifs".

  • expiry_time - Duration in ISO 8601 format for which the user-supplied or auto-generated passphrase is valid. Expiration time must not be greater than seven days into the future. ISO 8601 duration format is "PnDTnHnMnS" or "PnW" where n is a positive integer. The nD, nH, nM and nS fields can be dropped if zero. "P" should always be present and "T" should be present if there are any hours, minutes or seconds fields.

  • encryption_proposed (none/tls-psk) - Encryption mechanism of the communication channel between the two peers.

Do not provide remote IP

This method is used when the remote IP address is not provided. This method is used when the filer is ready to accept peering request from foreign clusters.

Required properties

  • generate_passphrase (true) - This option must be set to true. ONTAP automatically generates a passphrase to authenticate cluster peers. Either set generate_passphrase to true or provide a passphrase in the body of the request; only one of them is required.

Optional properties

The following fields are optional for a POST on /cluster/peer/. All fields must follow the structure in the cluster peer API definition.

  • name - Name of the remote peer.

  • ipspace - IPspace of the local intercluster LIFs. Assumes Default IPspace if not provided.

  • initial_allowed_svms - Local SVMs allowed to peer with the peer cluster's SVMs. This list can be modified until the remote cluster accepts this cluster peering relationship.

  • local_network - Fields to create a local intercluster LIF. See section on "Creating local intercluster lifs".

  • expiry_time - Duration in ISO 8601 format for which the user-supplied or auto-generated passphrase is valid. Expiration time must not be greater than seven days into the future. ISO 8601 duration format is "PnDTnHnMnS" or "PnW" where n is a positive integer. The nD, nH, nM and nS fields can be dropped if zero. "P" should always be present and "T" should be present if there are any hours, minutes or seconds fields.

  • encryption_proposed (none/tls-psk) - Encryption mechanism of the communication channel between the two peers.

Additional information

As with creating a cluster peer through the CLI, the combinations of options must be valid in order for the create operation to succeed. The following list shows the combinations that will succeed and those that will fail:

  • a passphrase only (fail)

  • a peer IP address (fail)

  • a passphrase with an expiration time > 7 days into the future (fail)

  • peer IP address and a passphrase (OK)

  • generate_passphrase=true (OK)

  • any proposed encryption protocol (OK)

  • an IPspace name or UUID (OK)

  • a passphrase, peer IP address, and any proposed encryption protocol (OK)

  • a non empty list initial allowed vserver peer names or UUIDs. (OK)
