Release Information

Statement introduced in Junos OS Evolved Release 19.3R1 for PTX10003-80C and PTX10003-160C routers.

Hierarchy introduced in Junos OS Evolved Release 20.1R2 for JNP10K-LC1201 line card on PTX10008 routers.


, you cannot use port 1,3, 6 and/or 7 of the same logical PIC.

(PTX10003-80C and PTX10003-160C routers) While setting port 0 to 400-Gigabit Ethernet mode (using QSFP56-DD-400GBASE-LR8 optics), the total bandwidth (speed x number-of-subports) of port 1 has to be less than 100G and port 2 has to configured as 'unused'. When using port 4 as 400G, port 3 has to be configured with total bandwidth and port 2 has to be configured 'unused'. Similarly, with port 5, 9 using 400G, port 6, 8 respectively has to be configured for less than 100G and port 7 should be configured as 'unused'. That is, when a port is configured in 400-Gigabit ethernet mode, you cannot configure speed of the adjacent port to be more then 100-Gbps, and the middle port (2 between 0~4 or 7 between 5~9) must be set to unused. To set a particular port to unused port, use unused CLI command.

Refer to Configuring 400-Gigabit Ethernet Interfaces on PTX10003 Routers for more information.

(JNP10K-LC1201 on PTX10008 routers) To control the number of interfaces created on a physical port, use the unused statement. If you configure a port as unused, no interfaces (Channelized or non-channelized) are created for that port irrespective of the port profile configuration for that port.
