Hardware

The PTX10016 is supported on Junos OS Evolved Release 21.4R1. See Feature Explorer for the full list of supported features.

Support for New PTX10016 Router Configurations—In Junos OS Evolved Release 21.4R1, we introduce the following new configurations of the PTX10016 router that support JNP10016-SF3 switch interface board (SIB):

PTX10016-BASE3
PTX10016-PREM2
PTX10016-PREM3

The new SIB provides higher routing capacity and support for the PTX10K-LC1201-36CD and PTX10K-LC1202-36MR line cards.

We also introduce a new front door (JNP10016-FRNT-PNL) that supports side EMI deflectors and a new rack mount kit (JNP10004-RMK-4POST).

To install the PTX10016 router hardware and perform initial software configuration, routine maintenance, and troubleshooting, see PTX10016 Packet Transport Router Hardware Guide. See Feature Explorer for the complete list of features for any platform. See PTX10016 Switch Fabric for more information about the SIBs. See PTX10016 Components and Configurations for more information about the router configurations.

Table 1: Features Supported on PTX10016 Devices
Feature	Description
Class of Service (CoS)	Support for CoS features includes classifiers (behavior aggregate (BA), fixed, and multifield (MF)) rewrite rules, forwarding classes, loss priorities, transmission scheduling, rate control, and drop-profiles. [See CoS Features and Limitations on PTX Series Routers.]
Interfaces and Chassis	Support for redundant power supply includes environment monitoring. Use the `request chassis fpc` command to override the default power budget for an FPC line card. The SFBs have a higher priority over the line cards for power allocation. [See Managing Power and fpc command (PTX Series).] Fabric manager support for: PFE PTX10K-LC1201-36CD line card CCL link training and error handling fabric statistics collection RE switchover handling for SIB, and reduced SIB initialization time. [See PTX-10016 System Overview.] Support for chassis to run with one or two RCBs. [See PTX10016 Routing and Control Board Components and Descriptions.]
Licensing	You need a license to use the software features on the PTX10016 devices. [To find out the features supported on this device, see PTX10016 Routers Support for the Juniper Flex Program . To add, delete, and manage licenses, see Managing Licenses.]
Services and Applications	Support for the following functionalities: IPv4 and IPv6 support for gateway [See Protocol-Independent Routing Properties User Guide and BGP User Guide.] IPv4 and IPv6 inline flow monitoring. [See Understanding Inline Active Flow Monitoring.] Tunneling for MPLS over UDP packets over RSVP LSPs and CSC, MPLS over Dynamic GRE with dynamic scaling option for number of tunnels up to 256K. [See Configuring a Next-Hop-Based Dynamic GRE Tunnels.] Dynamic next-hop tunnel localization and dynamic GRE Tunnel creation based on new IPv4-mapped-IPv6 next-hops. [See Next-Hop-Based Dynamic Tunnel Localization Overview.] Dynamic next-hop tunnel statistics reporting. [See Overview of Junos Telemetry Interface.] BGP Signaling for MPLS over UDP and MPLS over GRE tunnels. [See Configuring MPLS over GRE.] Mapping single IPv6 anycast address on multiple PFEs. [See get-route-range and IPv4 over IPv6.]
Resiliency	Platform resiliency support with logs, actions, faults, component recovery, and enhanced debugging capability for hardware failures. [See Understanding Chassis Alarms.] Resiliency support for RCBs with fault-handling actions. [See PTX-10016 RCB Components.] Fabric resiliency support for the PTX10K-LC1202-36MR line card (JNP10K-LC1202) for the links between FPCs. [See PTX-10016 Line Card Components.]

Express4 ASIC temperature-based performance throttling (PTX Series)—PTX devices have five Express4 ASICs, each capable of operating at 3.2Tbps for a total of 14.4Tbps per line card with various temperature sensors for software monitoring and alarm issuance. If the Express4 ASICs get too hot, the line card shuts down. Reducing the Express4 ASIC performance reduces power consumption and reduces the ASIC shutdown temperature. To avoid a shutdown on the line card, performance throttling is enabled by default. Use the command set chassis fpc slot pfe pfe-id temp-perf-throttle disable to disable performance throttling. show chassis fpc slot pfe-instance detail displays the real-time status of all the available PFEs and whether the temperature throttle is on. [See fpc, show chassis fpc, and show system errors active.]
