| 1. An apparatus comprising:
a standard port on a first routing platform, with the standard port adapted to receive a standard connector including a memory
device holding identification information that indicates whether the standard connector is a standard network connector operating
at a standard network rate or a stacking connector, utilized to form a stack connection with other routing platforms in a
stack, operating at a higher rate; and
a controller, coupled to the standard port, adapted to read the identification information from the memory device of a standard
connector plugged into the standard port to detect whether the standard connector is a stacking connector configured to transfer
data through the standard port at the higher rate or whether the standard connector is a standard network connector configured
to transfer data at the slower network rate; and
with the controller further adapted to either utilize the standard port on the first routing platform as a standard network
port configured to receive and transmit packets to a network connected to the first standard port if the controller detects
that the standard connector is a standard network connector or to utilize the standard port as a stack port configured to
be connected a second routing platform in the stack if the controller determines that the standard connector is a stacking
connector.
