P2-10G-40G-QSFPP PIC Overview
Starting with Junos OS Release 14.1R2 and 14.2R1, PTX5000 supports the P2-10G-40G-QSFPP PIC on the FPC2-PTX-P1A FPC.
All the ports on the P2-10G-40G-QSFPP PIC are plugged into quad small form-factor pluggable plus transceivers (QSFP+) that, in turn, are connected to fiber-optic cables that support both 10-Gigabit Ethernet standards and 40-Gigabit Ethernet standards, thereby enabling you to configure the PIC to operate either in 10-Gigabit Ethernet mode or in 40-Gigabit Ethernet mode.
Starting from Junos OS Release 15.1, you can perform the following on the P2-10G-40G-QSFPP PIC on PTX5000 routers:
You can configure the interfaces on this PIC to be a part of the mixed rates and mixed mode aggregated Ethernet bundles.
Port-based pseudowire class of service (CoS) classification which includes Layer 3 IPv4, IPv6, and MPLS classification for interfaces with ethernet-ccc encapsulation.
The following sections describe the P2-10G-40G-QSFPP PIC and the various framing modes that are supported on it:
Understanding Dual Configuration on P2-10G-40G-QSFPP PIC
All the ports on the P2-10G-40G-QSFPP PIC are QSFP+ based—that is, all the ports are connected to fiber-optic cables by means of QSFP+ transceivers.
The QSFP+ module—which includes the transceiver and the fiber-optic cable—supports the following standards on the P2-10G-40G-QSFPP PIC:
10-Gigabit Ethernet in LAN PHY framing mode (also known as native Ethernet mode) and WAN PHY framing mode.
40-Gigabit Ethernet in LAN PHY framing mode.
The P2-10G-40G-QSFPP PIC provides forty-eight 10-Gigabit Ethernet ports or twelve 40-Gigabit Ethernet ports. The PIC can be configured either in 10-Gigabit Ethernet mode or in 40-Gigabit Ethernet mode with the set chassis fpc fpc-number pic pic-number pic-mode (10G | 40G) configuration command. By default, the PIC is configured in 10-Gigabit Ethernet LAN PHY framing mode.
 | Note: If you want configure the PIC in 10-Gigabit Ethernet mode to operate in 40-Gigabit Ethernet mode, you must:
The PIC reboots and starts operating in the new mode. The same procedure is applicable when you can configure the PIC in 40-Gigabit Ethernet PIC to operate in 10-Gigabit Ethernet mode. In this case, you must execute the set chassis fpc fpc-slot pic pic-slot pic-mode 10G configuration mode command. |
To check the current diagnostics of the PIC, you must run the relevant operational mode CLI commands such as show chassis hardware, show interfaces, show interfaces diagnostics optics interface-name, and so on.
Port Numbering on P2-10G-40G-QSFPP PIC
Table 1 shows the port numbering in 40-Gigabit Ethernet mode and in 10-Gigabit Ethernet mode.

10-Gigabit Ethernet Mode
A 10-Gigabit Ethernet interface can operate in 10-Gigabit Ethernet LAN PHY framing mode or 10-Gigabit Ethernet WAN PHY framing mode.
You can configure a 10-Gigabit Ethernet interface at the [edit interface interface-name framing-mode (lan-phy | wan-phy)] hierarchy level to operate in 10-Gigabit Ethernet LAN PHY framing mode or in 10-Gigabit Ethernet WAN PHY framing mode.
Each P2-10G-40G-QSFPP PIC provides 48 physical interfaces. The interfaces are represented by the et-fpc/pic/QSFP+ port:channel interface naming convention, where the value of the QSFP+ port option ranges from 0 through 11 and the value of the channel option ranges from 0 through 3.
When a P2-10G-40G-QSFPP PIC is configured in 10-Gigabit Ethernet framing mode, it can operate in one of the following framing modes:
LAN PHY framing mode. Note that by default, the PIC is in 10-Gigabit Ethernet LAN PHY framing mode.
Note: The ports are set to LAN PHY framing mode by default when the framing-mode statement is not configured at the [edit interface interface-name] hierarchy level.
WAN PHY framing mode
40-Gigabit Ethernet Mode
You can configure twelve 40-Gigabit Ethernet interfaces that operate in LAN PHY framing mode. The interfaces are represented by the et-fpc/pic/QSFP+ port interface naming convention, where the value of the QSFP+ port option ranges from 0 through 11.
