Port numbers are assigned depending on whether the physical ports are partitioned into data lanes. To
illustrate,
shows the physical ports on the X690 front panel that can be partitioned.
on page 102 and
on page 103 detail how port numbers are assigned for each of the physical
ports.
Figure 102: X690 Ports that Can Be Partitioned into Data Lanes
The ports labeled 49-52 and 53-56 operate in 40 Gb mode, acting as single 40 Gb ports or multiple 10
Gb ports.
The ports labeled 57-60 and above operate in 40 Gb mode or 100 Gb mode, with a variety of speeds.
In 40-gigabit mode, each port can be partitioned into four 10-gigabit data lanes.
In 100-gigabit mode, each port can be partitioned into two 50-gigabit data lanes or four 25-gigabit data
lanes.
