Performing the Cluster Re-peer Process

In order to rebuild a cluster over a Layer 2 or Layer 3 fabric it’s necessary to use the fabric-join command with the repeer-to-cluster-node option.

For example, if one wants to join switch1 from switch3 to rebuild a cluster pair (that previously lost switch2), the following commands can be used:

• In case of a Layer 2 fabric:

CLI (network-admin@switch3) > fabric-join repeer-to-cluster-node switch1

• In case of a Layer 3 fabric (using for example OSPF or BGP for interconnection), the command changes to:

CLI (network-admin@switch3) > fabric-join repeer-to-cluster-node switch1 ?

password          plain text password

abort-on-conflict fabric join is aborted

delete-conflicts  conflicts are deleted

over-l3           fabric is over layer 3

Note: The over-l3 option is applicable only on Dell and Edgecore switches, where the fabric is over Layer 3 network.

CLI (network-admin@switch3) > fabric-join repeer-to-cluster-node switch1 over-l3

You can display the information about the fabric instance of the local switch using the fabric-info command:

CLI (network-admin@switch3) > fabric-info format all layout vertical
