Task Flow for Migrating Interfaces from Dedicated Mode to Shared Mode

To configure the 4-Gbps and 8-Gbps Fibre Channel switching modules migrating from dedicated rate mode to shared rate mode, follow these steps:

  1. Take unused interfaces out of service to release resources for other interfaces, if necessary.

    2. See the "Taking Interfaces Out of Service" topic.

  2. Configure the BB_credits and extended BB_credits, as necessary.

    3. See the "Configuring Buffer-to-Buffer Credits" topic, and the "Extended BB_credits on Generation 1 Switching Modules" topic.

  3. Configure the port mode.

    4. See the "Configuring Interface Modes" topic.

    Note     ISL ports cannot operate in shared rate mode.

  4. Configure the rate mode (dedicated or shared) to use.

    5. See the "Configuring Rate Mode" topic.

  5. Configure the traffic speed (1 Gbps, 2 Gbps, 4 Gbps, or autosensing with a maximum of 2 Gbps or 4 Gbps) to use.

    6. See the "Configuring Port Speed" topic.
