Licensing Requirements and Limitations for Traffic Distribution

Licensing Requirements and Limitations for Traffic Distribution

Involved Network Elements

The S12700 needs to work with a third-party network probe and packet analysis servers in order to properly configure traffic distribution.

Licensing Requirements

The traffic distribution function requires a License. If the License is unavailable, the traffic distribution commands can be run on the device, but cannot take effect.

For details about how to apply for a license, see S Series Switch License Use Guide.

Feature Limitations

  • The traffic distribution feature is supported by only optical interface cards, but not supported by electrical interface cards. In the following description, all the cards supporting the traffic distribution feature are optical interface cards.
  • The following are the cards supporting traffic distribution:
    • Unidirectional single-fiber communication: supported by ET1D2X12SSA0 card, E series cards (except EE series cards), and SC series cards.
    • Eth-Trunk-based distribution of packets with the same source address and destination address: supported by EA cards, EC cards, SC cards, and ET1D2X12SSA0.
    • ECMP-based distribution of packets with the same source address and destination address: not supported by X series cards.
    • Data integrity: supported by E series, ET1D2X12SSA0, and SC cards in S series.
  • After a device is configured to ensure data integrity, the device can only perform Layer 3 forwarding but cannot perform Layer 2 forwarding. Therefore, it is recommended that you configure the traffic distribution feature on a switch where no other features are configured to avoid the failure of features that use Layer 2 forwarding.
  • On a switch, after a traffic distribution License is loaded and the load-balance diffluence command is executed, the mac-address learning disable command is automatically executed on all interfaces to disable MAC address learning.
  • The unidirectional single-fiber communication function (single-fiber enable) and the MAC swap loopback function cannot be used together.
  • Eth-Trunk-based (load-balance diffluence) and ECMP-based (ecmp load-balance diffluence) flow pair distribution to the same server cannot be configured on the same device. The system will display an error message if you configure both of them on a device.
