System component Description
QSFP+ GbE ports VDX 6940-36Q - 36 40-GbE QSFP+ ports. 144 10-GbE ports using 10-GbE breakout cables.
VDX 6940-144S - 12 40-GbE QSFP+ ports. Forty-eight 10-GbE ports using 10- GbE breakout cables.
QSFP28 ports VDX 6940-144S - Up to 4 40/100-GbE dual personality ports can be congured for 100 GbE operation with
qualied 100-GbE transceivers installed.
NOTE
For each dual personality port congured for 100-GbE operation, 40-GbE operation is disabled on
three 40-GbE ports. Therefore, with a maximum of 4 100 GbE ports congured, all 40 GbE port
operation is disabled.
