Bonding Ethernet Ports

Bonding Ethernet Ports

This section describes how to bond Ethernet ports on one controller.

Prerequisites

Ethernet ports to be bonded are not configured with any IP addresses.

Context

  • Port bonding provides more bandwidth and higher link redundancy. Although ports are bonded, each host still transmits data through a single port and the total bandwidth can be increased only when there are multiple hosts. Determine whether to bond ports based on site requirements.
  • Port bonding on a storage system has the following restrictions:
    • Only Ethernet ports that have the same rate and are on the same controller can be bonded.
    • Link aggregation (IEEE 802.3ad) is supported, but only applies to ports on the same interface module.
    • Ethernet ports on a SmartIO interface module cannot be bonded if they are in FC mode.
    • On direct-connection networks, the MTU of the bonded SmartIO ports must be the same as that of the hosts. On switched networks, the MTU of the bonded SmartIO ports must be the same as that of the switches and hosts.
    • Read-only users are unable to bond Ethernet ports.
    • Each Ethernet port can only be added to one bond port.
    • A member in a port group cannot be added to a bond port.
  • After Ethernet ports are bonded, MTU changes to the default value and you must set the link aggregation mode for the ports. On Huawei switches, you must set the ports to work in static LACP mode.

    The link aggregation modes vary with switch manufacturers. If a non-Huawei switch is used, contact technical support of the switch manufacturer for specific link aggregation configurations.

Procedure

  1. Choose System.
  2. Click the controller enclosure where the Ethernet ports reside.
  3. Click to switch to the rear view.
  4. Select an Ethernet port you want to bond and click Bond Port.

    The Bond Port dialog box and the selected port are displayed. The format of the port name is controller enclosure ID.interface module ID.port ID.

  5. Set the bond name and select ports to be bonded with the Ethernet port.

    1. Specify Bond Name.

      The name can contain:

      • Only letters, digits, periods (.), underscores (_), and hyphens (-).
      • 1 to 31 characters.
    2. From the Available Ports list, select the Ethernet ports you want to bond with the current Ethernet port.
    3. Click OK.

      A security alert dialog box is displayed.

  6. Confirm the bonding of the Ethernet ports.

    1. Confirm the information in the dialog box and select I have read and understand the consequences associated with performing this operation.
    2. Click OK.

      The Success dialog box is displayed.

    3. Click OK.
    NOTE:

    After the bond port is successfully created, the Confirm dialog box is displayed. You can click OK to configure an IP address for the bond port.
