Techniques are disclosed to provide arbitration between input ports and output ports of a switch. For each of at least one input port of a group of input ports, a respective request is received specifying for the respective input port to be allocated a clock cycle in which to send data to a group of output ports. A grant of the request of a primary input port is issued at each clock cycle, the primary input port including a first input port of the at least one input port. Upon a determination, subsequent to a first clock cycle count elapsing, that an input arbiter has not yet accepted any grant of the request of the primary input port, a grant is issued at each clock cycle, including alternating between issuing a grant of the request of the primary input port and of an alternate input port, respectively. |
