Figure 48. 40GbE QSFP+ Port Numbering
On the 6-Port 40GbE QSFP+ line card, ports are numbered from 0 to 5 and operate by default in 40GbE
mode. If you use a breakout cable, each port can operate in 10G mode. 40GbE ports are numbered in
multiples of four, starting with zero; for example, 0, 4, 8, 12, and so on. When you install a breakout cable,
the resulting four 10GbE ports are numbered with the remaining numbers. For example, 40GbE port 0
contains 10GbE ports 0, 1, 2, and 3; 40GbE port 4 contains 10GbE ports 4, 5, 6, and 7.
NOTE: To locate a 4x10G port, enter the system location-led interface {fortyGigE |
tengigabitethernet} slot/port on command. The 4x10G port LED turns solid blue.
