Methods and systems for an out-of-credit timer in a network device

Method and system for reporting out-of-credit condition for a network device connected to a network. An indication to an out-of credit logic is provided that a first sub-port operating using a first protocol is out of credit to transmit information from a transmit segment. The first sub-port is a part of a base-port that includes a plurality of sub-ports that can be configured to operate at more than one operating speed to process packets complying with different protocols. The out-of-credit logic determines when the first sub-port is out-of-credit for a threshold period of time, and reports that the sub-port is out-of-credit to a processor of the network device.
