Try this configuration:
PTX1k-1
set chassis fpc 0 pic 0 port 36 speed 40g
Please note that this command will configure these 3 ports to operate at 40GB
36,37,38
PTX1k-2
set chassis fpc 0 pic 0 port 69 speed 40g
Please note that this command will configure these 3 ports to operate at 40GB
69.70,71
Do you want to know why it behaves like this ? is this expected?
Yes, it is, All network ports on the PTX1000 can be configured as 40-Gigabit Ethernet interfaces. You must configure 40-Gigabit Ethernet interfaces in groups of three network ports. When the port speed is configured as 40 Gbps on the first port in a port group, all three ports in the port group operate at 40 GB.
