Setting Parameters for Interworking Between a Huawei Datacom Device and a Non-Huawei Device

Setting Parameters for Interworking Between a Huawei Datacom Device and a Non-Huawei Device

Context

To implement interworking between a Huawei datacom device and a non-Huawei device, configure the fast transition mode according to the Proposal/Agreement mechanism of the non-Huawei device. The switch supports the following modes on the Proposal/Agreement mechanism:

  • Enhanced mode: The port participates in calculation of the root port when calculating the synchronization flag bit.
    1. An upstream device sends a Proposal message to a downstream device, requesting fast transition. After receiving the message, the downstream device sets the port connected to the upstream device as a root port and blocks all non-edge ports.

    2. The upstream device then sends an Agreement message to the downstream device. After the downstream device receives the message, the root port transitions to the Forwarding state.

    3. The downstream device sends an Agreement message to the upstream device. After receiving the Agreement message, the upstream device sets the port connected to the downstream device as a designated port, and the designated port transitions to the Forwarding state.

  • Common mode: The port ignores the root port when calculating the synchronization flag bit.
    1. An upstream device sends a Proposal message to a downstream device, requesting fast transition. After receiving the Proposal message, the downstream device sets the port connected to the upstream device as a root port and blocks all non-edge ports. The root port then transitions to the Forwarding state.

    2. The downstream device sends an Agreement message to the upstream device. After receiving the Agreement message, the upstream device sets the port connected to the downstream device as a designated port, and the designated port transitions to the Forwarding state.

On a network running VBST protocol, a Huawei datacom device and the connected non-Huawei device may fail to communicate if they use different Proposal/Agreement modes. The Huawei datacom device can select the same mode as that on the non-Huawei device to implement interworking.

Pre-configuration Tasks

Before setting parameters for interworking between a Huawei datacom device and a non-Huawei device, complete the following task:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The view of the interface that participates in spanning tree calculation is displayed.

  3. Run stp no-agreement-check

    The common mode is configured.

    By default, the enhanced mode is used on a port.

  4. Run commit

    The configuration is committed.
