•
Only the interfaces at the outer edge of each QSFP-DD group can be configured for 1x400 Gbps (using
QSFP56-DD optics).
•
The middle QSFP-DD port that is shared across two PFE’s (port 2 and port 7) cannot support a data rate
of 1x200 Gbps. These ports can only support 2x100 Gbps (QSFP28-DD).
•
The highest QSFP-DD data rate that can be used across all QSFP-DD groups is 200 Gbps (2x100 Gbps).
This provides 16 Tbps throughput for the PTX10003-160C, and 8 Tbps throughput for the
PTX10003-80C.
•
Aside from running all interfaces with 2x100 Gbps optics, there are other ways to attain the maximum
system throughput. The 400 Gbps optics can be used in combination with 100 Gbps optics and 200 Gbps
optics as shown in the following examples.
Allowable QSFP-DD Interface Configurations for the PTX10003-160C
Assuming the limitations described previously, Table 4 on page 29 lists the allowable interface configurations
for the PTX10003-160C.
