Claim:
1. A method for verifying a switch unit, the method comprising: detecting a runtime switch-over of a switch unit from communicating on a port according to a first protocol to communicating according to a second protocol; quiescing traffic of the first protocol from a first protocol driver through the switch unit; starting test traffic of the second protocol from a second protocol driver through the switch unit, wherein the second protocol driver is external to the switch unit and generates the test traffic for verifying that the switch unit operates in conformity with the second protocol; and verifying operation of the switch unit in response to the test traffic of the second protocol from the second protocol driver based on compliance with the second protocol, wherein the switch unit comprises a logical protocol multiplexor, a first logical protocol processing unit associated with the first protocol, and a second logical protocol processing unit associated with the second protocol, and wherein communications according to the first protocol and communications according to the second protocol share a same interface of the switch unit.
