PTX10000 Line Card Components and Descriptions

PTX10K-LC1101 Line Card

• Overview

• Channelizing 40-Gigabit Ports

• Network Ports

Overview

The line cards in PTX10000 routers combine a Packet Forwarding Engine and Ethernet interfaces in a single assembly. Line cards are field-replaceable units (FRUs) that can be installed in the line card slots on the front of the router chassis. The line cards are hot-insertable and hot-removable; you can remove and replace them without powering off the router or disrupting router functions. PTX10000 line cards use a common naming convention, where JNP10K-LC1101 is the name used on the overlay for the LC1101 line card. See Figure 1.

2 — Network ports

Each QSFP28 socket supports:

• 100-Gigabit Ethernet using QSFP28 optical transceivers. When a QSFP28 transceiver is inserted into any of the ports, the QSFP28 socket is enabled for 100-Gigabit Ethernet.

• 40-Gigabit Ethernet using QSFP+ optical transceivers. When a QSFP+ transceiver is inserted into any of the ports, the QSFP+ socket is enabled for 40-Gigabit Ethernet.

Channelizing 40-Gigabit Ports

40-Gigabit Ethernet ports on the PTX10K-LC1101 line card can be channelized to 10-Gigabit Ethernet. When ports are in channelization mode, the fourth port on each Packet Forwarding Engine is disabled, and the remaining four ports that are mapped to the same Packet Forwarding Engine can be used as either 4x10 Gigabit Ethernet, 40-Gigabit Ethernet, or 100-Gigabit Ethernet ports. The channelization mode works independently for each of the Packet Forwarding Engine on the PTX10K-LC1101 line card. See Figure 2 to see which ports are disabled and see Table 2 for the maximum port configurations.

Figure 2: Disabled Ports in Channelization Mode

Unlike the PTX10K-LC1102 line card, the PTX10K-LC1101 line card does not have port groups; instead, port behavior is tied to the ASIC associated with the port. You must configure each port individually, in order to channelize a 40-Gigabit Ethernet port to 4 independent 10-Gigabit Ethernet ports. See Table 3 for the list of available ports and the associated ASIC and Figure 2 to locate the available and disabled ports.

To change from the default mode to 40-Gigabit Ethernet channelized mode, use the Junos OS operational command set chassis fpc slot-number pic 0 port port number channelization-speed 10g.

Network Ports

Each of the 30 QSFP28 ports supports:

• 100-Gigabit Ethernet QSFP28 transceivers

• 40-Gigabit Ethernet QSFP+ transceivers

PTX10K-LC1102 Line Card

• Overview

• Network Ports

Overview

The line cards in PTX10000 routers combine a Packet Forwarding Engine and Ethernet interfaces in a single assembly. Line cards are field-replaceable units (FRUs) that can be installed in the line card slots on the front of the router chassis. The line cards are hot-insertable and hot-removable; you can remove and replace them without powering off the router or disrupting router functions. PTX10000 line cards use a common naming convention, where JNP10K-LC1102 is the name used on the overlay for the LC1102 line card. See Figure 3.

Figure 3: PTX10K-LC1102 Port Panel

2 — Network ports

Each QSFP28 socket can be configured to support:

• 100-Gigabit Ethernet using QSFP28 optical transceivers. When a QSFP28 transceiver is inserted into the ports marked with a fine black line underneath the socket and the port is configured for 100-Gigabit Ethernet, the two adjacent ports are disabled and the QSFP28 socket is enabled for 100-Gigabit Ethernet.

• 40-Gigabit Ethernet using QSFP+ optical transceivers.

• 10-Gigabit Ethernet using breakout cabling and attached optical transceivers. When configured for channelization, the system converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit Ethernet ports.

Network Ports

Each of the 12 QSFP28 ports supports:

• 100-Gigabit Ethernet QSFP28 transceivers

• 40-Gigabit Ethernet QSFP+ transceivers

Each of the 36 QSFP+ ports supports:

• 40-Gigabit Ethernet QSFP+ transceivers

Every second and sixth port in a 6XQSFP cage on a LC1102 supports 100-Gigabit Ethernet using QSFP28 transceivers. These 100-Gigabit Ethernet ports work either as 100-Gigabit Ethernet or as 40-Gigabit Ethernet, but are recognized as channelized 4x10-Gigabit Ethernet by default. See Figure 4 for a closeup view of a 6XQSFP+ cage. When a 40-Gigabit Ethernet transceiver is inserted into a 100-Gigabit Ethernet port, the port recognizes the 40-Gigabit Ethernet port speed. When a 100-Gigabit Ethernet transceiver is inserted into the port and enabled in the CLI, the port recognizes the 100-Gigabit Ethernet speed and disables two adjacent 40-Gigabit Ethernet ports. See Figure 5 and Figure 6. You can also use an 100-Gigabit Ethernet transceiver and run it at 40-Gigabit Ethernet by using the CLI to set the port speed to 40-Gigabit Ethernet.

Figure 4 shows the location of QSFP+ ports for the PTX10K-LC1102.

Figure 4: All Ports Are Enabled for Channelized 4x10-Gigabit Ethernet by Default

Figure 5: 100-Gigabit Ethernet Ports

Figure 6: 100-Gigabit Ethernet Port Disables Two Associated 40-Gigabit Ethernet Ports

The 40-Gigabit Ethernet ports can operate independently, be channelized into four 10-Gigabit Ethernet ports, or bundled with the next two consecutive ports and channelized into twelve 10-Gigabit Ethernet ports as a port range. Only the first and fourth port in each 6XQSFP cage are available to channelize a port range (see Figure 7). The port speed must be configured using the set chassis fpc pic port speed command. For example, to channelize the first router port, use the set chassis fpc 0 pic 0port 1speed 10g command.

Figure 7: Use the First and Fourth Port in Each 6XQSFP Cage to Channelize a Port Range

Table 4 shows the available combinations for the ports. On the LC1102, the ports are enabled by default.

Each PTX10K-LC1104 has six physical interfaces (ot-x/x/x) that connect to one of three built-in flexible rate optical transponders for a maximum of 24 physical interfaces on a PTX10000 system.. Each transponder connects four 100-Gigabit Ethernet logical interfaces (et-x/x/x) to one of three forwarding ASICs. The ASICs through a MACsec to PHY to MACsec encryption is optionally supported on each 100-Gigabit Ethernet interface. See Figure 9.

Figure 9: PTX10K-LC1104 Interfaces

Each of the six network ports can operate in one of three modulation formats; see Table 5.

Compatibility

The Juniper Networks Open Cloud Interconnect solution includes integrated 100-GbE coherent optics on Juniper Networks QFX Series switches; MX Series 5G Universal Routing Platforms and PTX Series Packet Transport Routers; and BTI Packet Optical Platforms optimized for DCI. As part of the Open Cloud Interconnect solution, the PTX10K-LC1104 coherent line card is compatible with many third-party optical products as well as Juniper Networks optical solutions and offerings. The PTX10K-LC1104 coherent line card is interoperable with the BTI Series Packet Optical Transport UFM6 in 100-Gbps, and 200-Gbps modes. It is also compatible with the MX Series MICs and PTX Series PICs in 100-Gbps mode. See Table 6.

Optical Transmit Specifications

The line card is connected using single-mode fiber (SMF) and LC connectors. See Table 7 and Table 8 for the optical transponder specifications.

Optical Receive Specifications

Status and Activity LEDs

There are two types of LEDs for the network ports: port LEDs and Ethernet link LEDs. The LEDs for the six physical ports indicate the link state of an ot interface. There are four LEDs in between each port pair that indicate the link state of the associated et interfaces, see Figure 10. To determine the link state of the ot interface; see Table 9.

Figure 10: DWDM Port and Ethernet Link State LEDs

1 — Port LEDs (ot interfaces)

Overview

The line cards in PTX10000 Packet Transport Routers combine a Packet Forwarding Engine and Ethernet interfaces in a single assembly. Line cards are field-replaceable units (FRUs) that can be installed in the line card slots on the front of the switch chassis. The line cards are hot-insertable and hot-removable; you can remove and replace them without powering off the switch or disrupting switch functions. See Figure 11.

Figure 11: PTX10K-LC1105 Port Panel

2 — Network ports

Network Ports

Each of the 30 QSFP28 ports supports:

• 100-Gigabit Ethernet using QSFP28 optical transceivers. When a QSFP28 transceiver is inserted into any of the ports, the QSFP28 port is enabled for 100-Gigabit Ethernet.

• 40-Gigabit Ethernet using QSFP+ optical transceivers. When a QSFP+ transceiver is inserted into any of the ports, the QSFP+ port is enabled for 40-Gigabit Ethernet.

On the PTX10K-LC1105, the ports are enabled by default, and the default configuration adds the ports to the default VLAN.

Power and Status LEDs

The two LEDs to the left of the network ports indicate the power (PWR) and status (STS) for the line card. See Table 15 and Table 16.

Offline Button

The offline/online button is recessed below the faceplate directly below the status (STS) LED. You can take the PTX10K-LC1105 offline or online by using either of these two methods:

• Press the OFF button with a pin tool, such as a paperclip, until the STS LED goes out (about 5 seconds).

• Issue the CLI command:

  user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline

Port Status and Activity LEDs

Each QSFP28 port has a bi-colored up or down LED indicator that show port status and link activity. See Figure 12 and Table 17.

PTX10K-LC201 for PTX10008 and PTX10016 Routers

• Overview

• Network Ports

Overview

The PTX10K-LC201 line card combines Packet Forwarding Engine (PFE) based on Juniper Networks custom BT ASICs, a local Broadwell-DE CPU, and the 400 Gigabit Ethernet quad small form factor double density (QSFP56-DD) interfaces. Each lane of the QSFP56-DD supports 56 Gbps PAM4. You can channelize the QSFP56-DD ports using breakout cables to speeds of 200 Gbps, 100 Gbps, 50 Gbps, 25 Gbps, 10 Gbps, or 1 Gbps. See Figure 13.

Figure 13: PTX10K-LC201 Port Panel

1 — Status LEDs

2 — 36 QSFP56-DD ports

The PTX10K-LC201 line card is supported on PTX10008 and PTX10016 models running Junos OS Evolved Release 19.4R1 and later. The line card also requires these hardware components:

• Routing and Control Board (RCB). JNP10K-RE1, JNP10K-RE1-LT, or JNP10K-RE1-128G

• Enhanced Switch Interface Boards (SIBs)

The PTX10K-LC201 line card can operate with the standard fans, (JNP10008-FAN or JNP10016-FAN), fan tray controllers (JNP10008-FAN-CTRL), and standard power supplies (JNP10K-PWR-AC and JNP10K-PWR-DC).

Network Ports

The QSFP56-DD ports support:

• 400 Gigabit Ethernet transceivers (QSFP56-DD)

• 400 Gigabit Ethernet active optic cables (AOCs)

• 4 x 100 Gigabit Ethernet transceivers (QSFP56-DD)

• 2 x 100 Gigabit Ethernet transceivers (QSFP566-DD)

• 100 Gigabit Ethernet transceivers (QSFP28)

• 100 Gigabit Ethernet AOCs

Hardware Features

The line cards in PTX10008 and PTX10016 routers combine a Packet Forwarding Engine and Ethernet interfaces in a single assembly. Line cards are field-replaceable units (FRUs) that can be installed in the line card slots on the front of the chassis. The line cards are hot-insertable and hot-removable; you can remove and replace them without powering off the router or disrupting router functions. See Figure 14.

Figure 14: QFX10000-60S-6Q Port Panel

1 — Power LED, status LED, and offline button	3 — QSFP28 ports, QSFP+ ports, and port groups
2 — SFP+ ports

Each QSFP28 port (60 and 64) controls a port group and can be configured to support:

• 100-Gigabit Ethernet using QSFP28 optical transceivers. The interface speeds are configured by port group. When a QSFP28 transceiver is inserted into the one of the QSFP28 ports marked with a fine black line above the port (60 or 64) and the port is configured for 100-Gigabit Ethernet, the two adjacent ports are disabled and the QSFP28 port is enabled for 100-Gigabit Ethernet. When port 60 is configured for 100-Gbps, ports 61 and 62 are disabled; when port 64 is configured for 100-Gbps, ports 63 and 65 are disabled.

• 40-Gigabit Ethernet using QSFP+ optical transceivers. The default speed is 10 Gbps.

• 10-Gigabit Ethernet using breakout cabling and attached optical transceivers. When configured for channelization, the system converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit Ethernet ports. Use the set chassis fpc fpc-slot-number pic pic-slot-number port port-number speed speed command to change the port speed.

Each QSFP+ port (61, 62, 63, and 65 is part of a port group and is controlled either by the associated QSFP28 port (60 or 64). A QSFP28 port operating at 40-Gpbs speeds, the QSFP+ ports can be configured to support:

• 40-Gigabit Ethernet using QSFP+ optical transceivers. The default speed is 10 Gbps.

• 10-Gigabit Ethernet using breakout cables with attached optical transceivers. When configured for channelization, the system converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit Ethernet ports. Use the set chassis fpc fpc-slot-number pic pic-slot-number port port-number speed speed command to change the port speed.

Each SFP+ port (0 through 59) can be configured to support 10-Gigabit Ethernet using SFP+ optical transceivers. The default speed is 10 Gbps.

Copper SFP transceivers are only supported on the bottom two SFP+ rows. Because copper SFP transceivers (1000BASE-T) are physically larger than optical SFP transceivers (1000BASE-X), stacking copper SFP transceivers in all three rows causes internal damage to the line card. Optical SFP transceivers can be stacked and used in all SFP+ ports 0 through 59.

Any of the 66 ports 0 through 65 can be configured as either uplink or access ports. The ports are enabled by default, and the default configuration adds the ports to the default VLAN.

Port Groups

The six combination ports of QSFP28 and QSFP+ can operate either as six independent 40-Gigabit Ethernet ports or as two port groups. The first port group is controlled by QSFP28 port 60 and administratively bundled with QSFP+ ports 61 and 62. The second port group is controlled by QSFP28 port 63 and administratively bundled with QSFP+ ports 64 and 65. To enable the port group, insert a 100-Gigabit Ethernet transceiver into the QSFP28 port and configure a port for 100-Gbps. Junos OS enables the QSFP28 port at 100-Gbps speed and disables the two QSFP+ ports bundled in the port group. Figure 15 shows the location of QSFP28 ports and port groups for the QFX10000-60S-6Q. Table 18 shows the available combinations for the ports.

Figure 15: QFX10000-60S-6Q Port Groups

Channelization of 40-Gigabit Ethernet Ports

Channelization from a 40-Gigabit Ethernet port into 4 independent 10-Gigabit Ethernet ports is supported on the QSFP28 and QSFP+ ports. Channelization to 50-Gbps or 25-Gbps speed is not supported on the 100-Gigabit Ethernet QSFP28 port. All ports in the port group are channelized when port 60 or port 63 are channelized. Ports cannot be channelized individually.

To channelize a 40-Gbps port to 4 independent 10-Gbps ports, use the set chassis fpc fpc-slot-number pic pic-slot-number port port-number channel-speed speed command. For example, to channelize ports 60 through 62 for a line card in slot 6:

Review your configuration and issue the commit command.

If you want to return the port to the default, delete the speed statement from the configuration at the [chassis fpc 6 pic 1 port port-number] hierarchy level and commit the configuration. The network port is reset to the default 40-Gigabit Ethernet interface.

Using Copper and Fiber SFP Transceivers

When you configure the 10-Gigabit Ethernet ports 0 to 59 as 1-Gigabit Ethernet ports, you can use optical fiber SFP transceivers in any of the ports. However, copper SFP transceivers are restricted to the lower two rows. See Figure 16.

Figure 16: Supported Placement for Copper and Fiber SFP+ Transceivers

Because 1 Gbps copper SFP transceivers are physically larger than optical SFP transceivers, there is insufficient room for 3 copper SFP transceivers to be stacked. Use the top row only for optical SFP transceivers. You can stack copper transceivers in the bottom two rows. Ports are arranged belly-to-belly. Stacking three SFP transceivers in a column can damage the line card. For the recommended configuration, see Figure 17.

Figure 17: Belly-to-Belly SFP Transceivers

SFP+ Status and Activity LEDs

All status and activity LEDs for the SFP+ ports are located between the second and third rows of SFP+. The up arrow, circle, and down arrow indicate the row of the status. A bi-color LED indicates the status and activity. See Figure 18 and Table 19.

Figure 18: SFP+ Port Indicators and Status LEDs on a QFX10000-60S-6Q Line Card

• An up arrow indicates the first row.

• A circle indicates the second row.

• A down arrow indicates the third row.

QSFP+ and QSFP28 Status and Activity LEDs

All QSFP+ and QSFP28 ports have an up or down indicator for each port and four bi-colored LEDs that show port status and link activity based on whether or not the port is configured for channelization. See Table 20.

Figure 19: LED Indicators on QSFP+ and QSFP28 Ports on QFX10000-60S-6Q Line Card

PTX10000 Line Card LEDs

All PTX10000 line cards have three bi-colored LEDs (see Figure 20).

Figure 20: Line Card LEDs

Table 21 describes the functions of the line card LEDs.
