Description

This article guides on configuring port speeds for various Juniper MX Series routers using the pic-mode pic-speed statement. It outlines the supported speeds, hardware configurations, and considerations for achieving optimal port operation.

Symptoms

If the correct speed is not set the port will not be visible in the configuration despite connecting the SFP on the port

Solution

The pic-mode statement allows you to configure the operating speed of all ports on supported platforms, including the MPC7E-MRATE MPC, MIC-MRATE MIC, MX10003 MPC, and MX204 routers. Supported port speeds vary by platform and hardware, with options for 100G, 40G, 10G, and 1G on different configurations.

Platform-Specific Details

1. MX240, MX480, MX960, MX2010, and MX2020 (with MPC7E-MRATE)

  • Supported Speeds: 100G, 40G, and 10G.
  • PIC Configuration:
    • Ports on PIC 0 and PIC 1 support 40G and 10G speeds.
    • Ports 2 and 5 on both PICs also support 100G speed.
    • Configuring 100G disables ports 0, 1, 3, and 4 and reboots the PIC.

2. MX2010 and MX2020 (with MIC-MRATE on MPC8E/MPC9E)

  • MPC8E:
    • 100G: Supports only 4 out of 12 ports (ports 0, 1, 6, and 7). The remaining ports are disabled.
    • 40G/10G: Enables all ports at the configured speed.
  • MPC9E:
    • 100G: Supports 8 out of 12 ports (ports 0, 1, 2, 3, 6, 7, 8, and 9). Other ports operate at 40G/10G.
    • 40G/10G: Enables all ports.

3. MX10003 (with MX10003 MPC)

  • Supported Speeds: 100G, 40G, and 10G.
  • Configuration Notes:
    • PIC-level rate selectability configures all ports at the same speed.
    • Fixed PIC: All six ports support 40G and 10G speeds.
    • Multi-rate MIC: All 12 ports support 100G, 40G, and 10G.

For detailed information, refer to MX10003 MPC (Multi-Rate) and Supported Active Physical Ports on MX10003 MPC.


4. MX204

  • Supported Speeds: 100G, 40G, and 10G.
  • Configuration Notes:
    • PIC 0 ports: Four rate-selectable ports configurable as:
      • 100G or 40G per port.
      • Four 10G interfaces using breakout cables.
    • PIC 1 ports: Eight 10G ports.
    • Heterogeneous Mode Limitation: If 40G or 100G is configured on PIC 0, the number of ports on PIC 1 must be set to zero to prevent oversubscription.

For more details, refer to MX204 Router Overview and Supported Active Physical Ports on MX204.


5. MX240, MX480, MX960, MX2010, and MX2020 (with MPC2E-NG/MPC3E-NG)

  • Supported MICs: 10x10GE SFPP and 10x1GE SFP.
  • Configuration Notes:
    • Supports 10G and 1G speeds with PTP and MACsec capabilities.
    • PIC-level configuration enables uniform speed on all ports.
    • Slot indexing:
      • MIC in Slot 0: Appears under PIC 0.
      • MIC in Slot 1: Appears under PIC 2 (to avoid logical PIC mapping conflicts).

Options

OptionDescription
100GPorts operate at 100 Gbps speed.
40GPorts operate at 40 Gbps speed.
10GPorts operate at 10 Gbps speed.
1GPorts operate at 1 Gbps speed (where supported).

Default Value

The default operating speed is 10G.

  • Modify Configuration: interface-control

Notes

  • Use the port-checker tool to validate port combinations for specific configurations.
  • A PIC configured with 100G reboots, and specific ports may be disabled to prevent oversubscription.
  • When using breakout cables, configure ports as required for specific speeds and applications.
