Q
What are Juniper Router CTP modules and cards?
A
Juniper Router CTP (Compact Traffic Processor) modules and cards are modular hardware components that provide high-performance packet processing, forwarding, and traffic management functions within Juniper MX and PTX series routers.
Q
Which Juniper routers support CTP modules and cards?
A
CTP modules and cards are supported on Juniper MX Series (MX5, MX10, MX40, MX80, MX240, MX480, MX960) and PTX core routers (PTX5000, PTX10002, PTX10008), enabling scalable service delivery and backbone aggregation.
Q
How do I select the right CTP module for my network?
A
Choose a CTP module based on your router model, required port density (10 GbE, 40 GbE, 100 GbE), throughput capacity, and feature set such as MPLS, QoS, and intelligent traffic policing.
Q
Can CTP modules be installed while the router is powered on?
A
Yes. Juniper CTP modules support hot-swap installation and removal without disrupting packet forwarding or control-plane operations.
Q
How do I install a Juniper Router CTP card?
A
Power off the router or ensure hot-swap capability, insert the CTP card into the designated slot until it clicks, secure the ejector lever, then power on or verify operational status via CLI show chassis commands.
Q
What is the maximum throughput of Juniper CTP modules?
A
Throughput varies by model: 10 GbE CTP modules deliver up to 40 Gbps, 40 GbE modules up to 160 Gbps, and 100 GbE modules up to 400 Gbps per slot, depending on router platform.
Q
How do I update firmware on Juniper CTP modules?
A
Use Junos CLI commands such as request system software add <package> to install the correct Junos OS and firmware bundle, then reboot the module or router as directed in the release notes.
Q
Where can I find part numbers for ordering CTP modules?
A
Juniper part numbers are listed in the MX/PTX hardware compatibility guide or the Juniper online price list; reference the module type (e.g., MPC3E-3D, M120, MPC7E) and card model for accurate ordering.
Q
What power and cooling requirements apply to CTP modules?
A
Power consumption ranges from 50 W to 300 W per module; refer to your router’s hardware guide for rack-unit power budgets and ensure sufficient airflow and temperature control in the data center.
Q
How do I troubleshoot a faulty CTP module?
A
Check CLI logs (show log messages), verify interface counters (show interfaces extensive), inspect module LEDs for status, reseat the module, and upgrade firmware before contacting Juniper Support.
Q
What diagnostic tools are available for CTP cards?
A
Use Junos CLI commands (show chassis fpc, show interfaces diagnostics optics), Juniper Network Director, and SNMP MIBs to monitor optical levels, temperature, and module health in real time.
Q
Are Juniper CTP modules covered by warranty?
A
Yes. All genuine Juniper CTP modules and cards carry a limited lifetime warranty with options for NBD advance replacement, extended coverage, and Juniper Care support contracts.
Q
What is the end-of-life policy for CTP modules?
A
Juniper publishes EOL/EOS announcements at least 12 months in advance; check the Juniper Product Lifecycle page for timelines on last-order and last-supported dates to plan migrations.
Q
How can I migrate from older modules to the latest CTP cards?
A
Review compatibility matrices, back up configurations, perform an in-place OS upgrade if required, hot-swap the modules one slot at a time, and validate traffic flows after each replacement.
Q
What environmental standards do CTP modules meet?
A
Juniper CTP modules comply with NEBS Level 3, ETSI, RoHS, and WEEE standards, ensuring reliability in temperature ranges from 0 °C to 40 °C and relative humidity up to 85% non-condensing.
Q
How do I monitor performance on Juniper CTP cards?
A
Use Junos telemetry, SNMP polling (ifHCInOctets, ifHCOutOctets), RPM probes, and J-Flow to capture KPIs like throughput, latency, packet drops, and jitter directly from the CTP card.
