6.4 What Is the Bandwidth Limitation on the
S5700-SI&S5700-EI?
The S5700-SI&S5700-EI subcards in the front slot and rear slot use the same chip that
provides 4x10 Gbit/s bandwidth.
A stack card can be used with a 2x10G subcard. Two stack interfaces on the stack card
occupy 20 Gbit/s bandwidth, and the 2x10G subcard occupies 20 Gbit/s. A stack card cannot
be used with a 4x10GE subcard. The 10GE interfaces on the 4x10GE subcard are actually
10GE interfaces with their rates limited, so the actual bandwidth of the subcard is 4x10 Gbit/s.
This subcard occupies all the 4x10 Gbit/s bandwidth of the chip, so there is no available
bandwidth for the stack card.
