Mechanisms of improving firmware management performance and control of CMIS transceivers during such operations

A network device comprising:

• a management bus;
• a plurality of transceiver ports connected to the management bus;
• a transceiver manager connected to the management bus;
• wherein the transceiver manager is configured to:
• in response to determining that a first transceiver port of the plurality of transceiver ports is undergoing a communication-intensive operation on the management bus,
• identify a subset of the plurality of transceiver ports other than the first transceiver port, and
• reduce a polling frequency for each of the transceiver ports in the subset from a first polling frequency to a reduced polling frequency;
• determine, during the communication-intensive operation, that a management operation for the first transceiver port is pending;
• pause the communication-intensive operation;
• complete the management operation for the first transceiver port;
• resume the communication-intensive operation after the management operation for the first transceiver port has been completed;
• and
• in response to determining that the communication-intensive operation has completed, reset the polling frequency of the transceiver ports in the subset to the first polling frequency.

A network device comprising:

• a transceiver manager;
• a plurality of management buses connected to the transceiver manager, each management bus being connected to a corresponding transceiver;
• wherein the transceiver manager is configured to:
• in response to determining that a first transceiver port connected to a first one of the management buses is undergoing a communication-intensive operation,
• identify a subset of the plurality of management buses other than the first one of the management buses, and
• reduce a polling frequency for each of the transceivers connected to the subset of management buses from a first polling frequency to a reduced polling frequency;

• pause the communication-intensive operation;
• complete the management operation for the first transceiver port;
• resume the communication-intensive operation after the management operation for the first transceiver port has been completed;
• and
• in response to determining that the communication-intensive operation has completed, reset the polling frequency of the transceivers connected to the subset of management buses to the first polling frequency.
