Configuration requirements for BES-53248 cluster switches

Contributors netapp-yvonneo netapp-jolieg

For BES-53248 switch installation and maintenance, be sure to review EFOS and ONTAP support and configuration requirements.

EFOS and ONTAP support

See the NetApp Hardware Universe and Broadcom switches compatibility matrix for EFOS and ONTAP compatibility information with BES-53248 switches. EFOS and ONTAP support can vary by the specific machine type of the BES-53248 switch. For details of all BES-52348 switch machine types, see Components and part numbers for BES-53248 cluster switches.

Configuration requirements

To configure a cluster, you need the appropriate number and type of cables and cable connectors for the cluster switches. Depending on the type of cluster switch you are initially configuring, you need to connect to the switch console port with the included console cable.

Cluster switch port assignments

You can use the Broadcom-supported BES-53248 cluster switch port assignments table as a guide to configuring your cluster.

Switch ports Ports usage


10/25GbE cluster port nodes, base configuration


10/25GbE cluster port nodes, with licenses


40/100GbE cluster port nodes, with licenses, added right to left


100GbE cluster Inter-Switch Link (ISL) ports, base configuration

See the Hardware Universe for more information on switch ports.

Port group speed constraint

  • On BES-53248 cluster switches, the 48 10/25GbE (SFP28/SFP+) ports are combined into 12 x 4-port groups as follows: Ports 1-4, 5-8, 9-12, 13-16, 17-20, 21-24, 25-28, 29-32, 33-36, 37-40, 41-44, and 45-48.

  • The SFP28/SFP+ port speed must be the same (10GbE or 25GbE) across all ports in the 4-port group.

Additional requirements

  • If you purchase additional licenses, see Activate newly licenses ports for details on how to activate them.

  • If SSH is active, you must re-enable it manually after running the command erase startup-config and rebooting the switch.
