The MX10003-LC2103-EQ is a JNP1003/MX10003 Modular Port Concentrator featuring six QSFP+ ports, one MIC slot, and Enhanced Queuing for optimized packet handling.
This MPC provides six QSFP+ interfaces supporting 40 GbE / 4×10 GbE breakout configurations, enabling flexible high-speed connectivity.
Enhanced Queuing (EQ) mode prioritizes latency-sensitive traffic through dynamic buffer allocation and strict priority scheduling to ensure optimal performance.
The MX10003-LC2103-EQ requires a compatible MIC slot such as the MPC2 line of Modular Interface Cards or higher, ensuring full feature support.
Yes, the MPC 6xQSFP+ is fully supported on all Juniper MX10003 routers running Junos OS Release 20.4R1 or later.
To install, power down the MX10003 chassis, insert the MPC into an available slot, secure the latch, then restart the router and verify with show chassis hardware.
The MPC delivers up to 240 Gbps of total throughput (6×40 GbE) in native mode or 240 Gbps when using 4×10 GbE breakout per QSFP+ port.
Yes, each QSFP+ port supports 4×10 GbE breakout via standard DAC/AOC cables, enabling flexible port mapping for diverse network designs.
The MX10003-LC2103-EQ consumes approximately 65 W under full load, subject to environmental conditions and traffic patterns.
Common use cases include data center spine uplinks, cloud peering, and high-performance service provider edge aggregation requiring low latency and high throughput.
Enhanced Queuing mode is available starting with Junos OS Release 20.4R1 on MX10003 platforms; upgrade to that release or later to enable EQ.
Yes, the MX10003 chassis supports mixed MPC modules, provided that the total power budget and slot compatibility guidelines are observed.
Traffic is managed via Junos OS QoS policies, leveraging Enhanced Queuing, buffer profiles, and scheduler maps to meet SLAs and minimize congestion.
The MX10003-LC2103-EQ operates in 0 °C to 40 °C ambient temperature, 5%–90% non-condensing humidity, and meets NEBS Level 3 requirements.
