QSFP56-DD Network Ports

The PTX10001-36MR has 24 double density quad small-form factor pluggable (QSFP56-DD) sockets that are configured as 400GbE ports by default.

The QSFP56-DD network ports support:

  • QSFP56-DD transceivers

  • QSFP28-DD transceivers

  • QSFP28 transceivers

  • QSFP+ transceivers

  • Active optical cables (AOC)

  • Direct attach copper (DAC) cables

  • Direct attach copper break out (DACBO) cables

  • QSA adapters

Note:

Installing either the QDD-400G-LR8 or the QDD-400G-FR4 transceivers next to each other in ports 1, 3, 9, or 11 (on each logical PIC) is supported up to a maximum operating temperature of 35°C at an altitude of up to 6000 feet above sea level. For example, if you install either a QDD-400G-LR8 or a QDD-400G-FR4 transceiver in port 1 and port 3 of PIC 0, the maximum supported operating temperature and altitude combination is 35°C at 6000 feet above sea level. This restriction is due to thermal limitations.

Table 1 describes the maximum number of ports for each interface type supported by the QSFP56-DD ports.

To achieve maximum ports, break out cables maybe required.

Note:

Port speeds are configured using the set interfaces interface-name speed speed command. You configure ports to operate at a particular speed by using the appropriate speed option. If you configure a port to operate at a certain speed, and you want to return the port to the default configuration, delete the speed statement from the configuration at the [interfaces interface-name] hierarchy level and commit the configuration. The network port is reset to the default Ethernet interface.

See Port Speed on PTX10001-36MR Router Overview to learn about multiple port speeds supported on PTX10001-36MR router, guidelines, and how to configure the port speed.

QSFP28 Network Ports

The PTX10001-36MR has 12 quad small-form factor pluggable (QSFP28) sockets that are configured as 100GbE ports by default.

The QSFP28 network ports support:

  • QSFP28 transceivers

  • QSFP+ transceivers

  • Active optical cables (AOC)

  • Direct attach copper (DAC) cables

  • Direct attach copper break out (DACBO) cables

  • QSA adapters

Port Numbering

The interfaces for the PTX10001-36MR are divided into logical PICs and physical optical ports as follows:

  • PICs: There are three logical PICs, numbered 0, 1, and 2 from left to right.

  • Ports: Each PIC controls 8 QSFP56-DD ports, numbered 0 through 3 and 8 through 11 from left to right. Each PIC also controls 4 QSFP28 ports numbered 4 through 7 from left to right.

Each PIC uses the same port numbering.

Figure 2 shows how the PTX10001-36MR network ports are divided into the 3 PICs.

PTX10001-36MR Power Zone Restrictions

The ports on the PTX10001-36MR are organized in three power zones based on the power available to the ports in each zone. Table 3 describes the power zones, ports assigned to each zone, and the maximum power available to each zone. Figure 3 shows which ports belong to each power zone.

The total amount of power consumed by the optics inserted in the ports in each zone must not exceed the maximum power available to the power zone.

How to Configure the QSFP28 Ports for 10-Gbps, 25-Gbps, and 40-Gbps Speeds

The QSFP28 ports support 10-Gbps, 25-Gbps, 40-Gbps, and 100-Gbps speeds. 100-Gbps is supported on all QSFP28 ports. 10-Gbps, 25-Gbps, and 40-Gbps speeds are not supported on all QSFP28 ports.

Further, when these supported QSFP28 ports are configuring for 10-Gbps, 25-Gbps, or 40-Gbps speeds, there are corresponding QSFP28 ports that must be configured as unused.

Table 4 lists the ports that support 10-Gbps, 25-Gbps, or 40-Gbps speeds and which must be configured as unused .

You must configure these ports as unused through the CLI. The PTX10001-36MR does not automatically power off the ports.

Note:

The list of ports supported in Table 4 correspond to 3 logical PICs. For example, for port number 4 listed in the table, there are actually three ports numbered 4 on the PTX10001-36MR (one on each logical PIC) and all three ports support the same speeds.

Note:

You can configure one of the ports (odd or even) for 1x10-Gbps and the other port (odd or even) for 1x100-Gbps at the same time. In this scenario, you do not need to configure any ports as unused.

PTX10001-36MR Network Port LEDs

Each PTX10001-36MR network port uses a single bicolored LED to indicate link status, activity on the link, or a fault condition. The LEDs for the QSFP28 ports are located above the ports. The LEDs for the QSFP56-DD ports are located to the left of the ports. Figure 4 shows the location of the LEDs.
