Flow control configuration notes

  • Auto-negotiation of flow control is not supported on 10 Gbps and 40 Gbps ports, fiber ports, and copper or fiber combination ports.
  • When any of the flow control commands are applied to a port that is up, the port will be disabled and re-enabled.
  • For 10 Gbps and 40 Gbps ports, the show interface command with the appropriate parameters shows whether Flow Control is enabled or disabled, depending on the configuration.
  • When flow-control is enabled, the hardware can only advertise PAUSE frames. It does not advertise Asym.
