PTX3000 Host Subsystem

PTX3000 Host Subsystem Description

The host subsystem provides the routing and system management functions of the PTX3000. You can install one or two host subsystems. Depending on your configuration, a host subsystem consists of either a Routing Engine and a Control Board, or a Routing and Control Board (RCB) and RCB companion card. To operate, each host subsystem functions as a unit; the Routing Engine requires the corresponding Control Board, and the RCB requires the corresponding RCB companion card, and vice versa.

Note:

The RCB provides Routing Engine, Control Board, and Centralized Clock Generator (CCG) functionality in a single FRU. The RCB companion card is a FRU that provides backplane connectivity to the RCBs.

Note:

We recommend that you install two host subsystems for redundant protection. If you install only one host subsystem, we recommend that you install it in slots RE0 and CB0.

Note:

The primary and backup host subsystems must be the same type during normal operation. For example, if the primary host subsystem is an RCB with RCB companion card, the backup host subsystem must also be an RCB with RCB companion card.

If your configuration includes a Routing Engine and a Control Board, see the following topics for more information:

PTX3000 Routing Engine Description

Routing Engine Slots

You can install one or two Routing Engines in the PTX3000. The Routing Engines install in the slots to the left of the Control Boards labeled CB0 and CB1. If two Routing Engines are installed, one functions as the primary and the other acts as the backup. If the primary Routing Engine fails or is removed and the backup is configured appropriately, the backup restarts and becomes the primary.

Routing Engine Functions

The Routing Engine handles all routing protocol processes, as well as the software processes that control the router's interfaces, the chassis components, system management, and user access to the PTX3000. The routing and software processes run on top of a kernel that interacts with the Packet Forwarding Engines.

The Routing Engine constructs and maintains one or more routing tables. From the routing tables, the Routing Engine derives a table of active routes, called the forwarding table, which is then copied into the Packet Forwarding Engines. The design of the ASICs allows the forwarding table in the Packet Forwarding Engines to be updated without interrupting forwarding performance.

The Routing Engine includes the following functions and features:

  • Processing of routing protocol packets—The Routing Engine handles all packets that concern routing protocols, freeing the Packet Forwarding Engine to handle only packets that represent Internet traffic.

  • Software modularity—Because each software process is devoted to a different function and uses a separate process space, the failure of one process has little or no effect on the others.

  • In-depth Internet functionality—Each routing protocol is implemented with a complete set of Internet features and provides full flexibility for advertising, filtering, and modifying routes. Routing policies are set according to route parameters (for example, prefix, prefix lengths, and BGP attributes).

  • Scalability—Junos OS routing tables have been designed to hold all the routes in current networks with ample capacity for expansion. Additionally, Junos OS can efficiently support large numbers of interfaces and virtual circuits.

  • Management interface—Different levels of system management tools are provided, including the Junos OS CLI, the Junos XML management protocol, the craft interface, and SNMP.

  • Storage and change management—Configuration files, system images, and microcode can be held and maintained in primary and secondary storage systems, permitting local or remote upgrades.

  • Monitoring efficiency and flexibility—The PTX3000 supports functions such as alarm handling and packet counting on every port without degrading packet-forwarding performance.

Routing Engine Components

Each Routing Engine consists of the following components:

  • CPU—Runs Junos OS to maintain the routing tables and routing protocols.

  • DRAM—Provides storage for the routing and forwarding tables and for other Routing Engine processes.

  • EEPROM—Stores the serial number of the Routing Engine.

  • Interfaces for management access—Provide information about Routing Engine status to the external management devices (console, laptop, or terminal server) connected to the management ports on the Control Board.

PTX3000 Control Board Description

Control Board Slots

You can install up to two Control Boards in the PTX3000. Control Boards install into the front of the chassis in the slots labeled CB0 and CB1. A Routing Engine installs in a slot to the left of each Control Board. The Control Boards cannot function if a Routing Engine is not present.

If the PTX3000 contains a redundant host subsystem, one host subsystem functions as the primary and the other as its backup. If the primary fails or is removed, the backup restarts and becomes the primary.

Control Board Function

Each Control Board works with the Routing Engine to provide the following control, monitoring, and clocking functions for the PTX3000:

  • Determining Routing Engine primary role

  • Controlling power and reset for the other PTX3000 components

  • Monitoring and controlling fan speed

  • Monitoring system status

  • Providing Centralized Clock Generator (CCG) ports and a 19.44-MHz Stratum 3 clock signal for the Ethernet network interfaces on the PTX3000

Control Board Components

Each Control Board consists of the following components:

  • Ethernet switch used for intermodule communication.

  • PCI bus to the Routing Engines.

  • 19.44-MHz Stratum 3 clock.

  • Field-programmable gate array (FPGA) that performs multiplexing of clock sources.

  • Three RJ-45 management ports for connecting the Routing Engine to external management devices. The management ports on each Control Board connect to the Routing Engine installed into that Control Board. From these management devices, you can use the CLI to configure and manage the PTX3000. Each Control Board includes the following management ports:

    • HOST/ETHERNET—10/100-Mbps or 1-Gbps Ethernet port for connecting to a management network. This port connects the Routing Engine through a copper 10/100/1000 BASE-T Ethernet connection to a management LAN (or any other device that plugs into an Ethernet connection) for management of the PTX3000. The port uses an autosensing RJ-45 connector to support 10-Mbps, 100-Mbps, or 1-Gbps connections. Two small LEDs on the bottom edge of the port indicate the port speed and traffic on the port. The left LED is labeled Y=10/100 G=1000, and the right LED is labeled ACT.

PTX3000 Routing and Control Board Description

Routing and Control Board Slots

You can install one or two Routing and Control Boards (RCBs) in the PTX3000. The RCBs install in the slots labeled CB0 and CB1. If two RCBs are installed, one functions as the primary and the other acts as the backup. If the primary RCB fails or is removed and the backup is configured appropriately, the backup becomes the primary.

Note:

The RCB combines the functionality of a Routing Engine, Control Board, and Centralized Clock Generator (CCG) in a single FRU. Although the functionality is combined in a single FRU, you must install an RCB companion card in the RE0 and RE1 slots adjacent to each RCB to enable the RCBs to communicate through the backplane. Because the RCB companion cards are only used for communication between the RCBs, if you are installing a single host subsystem with no backup RCB, you do not need to install RCB companion cards (install Routing Engine blanks instead to ensure proper cooling).

The Routing Engine in the RCB is based on Intel’s multi-core Haswell processor, and provides higher computing power, higher memory, and higher storage for the operating system. It has a virtualized architecture where Junos OS runs as a virtual machine (VM) over a Linux-based host (VM Host).

The Control Board (CB) in the RCB provides control and management interfaces to all the FRUs in the chassis.

The CCG provides the central timing card function for the chassis, and distributes systemwide timing. The CCG is compliant with Synchronous Ethernet.

Note:

RCB primary role controls all aspects of the RCB, including the CCG ports. For example, when the RCB installed in slot CB0 is the primary RCB, the Routing Engine, Control Board, and CCG functions occur on that RCB. If primary role is switched to CB1, the RCB in that slot takes over the Routing Engine, Control Board, and CCG functions.

Routing and Control Board Function

The RCB handles all routing protocol processes, as well as the software processes that control the PTX3000 interfaces, the chassis components, system management, and user access to the PTX3000.

The RCB constructs and maintains one or more routing tables. From the routing tables, the RCB derives a table of active routes, called the forwarding table, which is then copied into the Packet Forwarding Engines in the flexible PIC concentrators (FPCs). The design of the ASICs allows the forwarding table in the Packet Forwarding Engines to be updated without interrupting forwarding performance.

The RCB includes the following functions and features:

  • Processing of routing protocol packets—The RCB handles all packets that concern routing protocols, freeing the Packet Forwarding Engine to handle only packets that represent Internet traffic.

  • Software modularity—Because each software process is devoted to a different function and uses a separate process space, the failure of one process has little or no effect on the others.

  • In-depth Internet functionality—Each routing protocol is implemented with a complete set of Internet features and provides full flexibility for advertising, filtering, and modifying routes. Routing policies are set according to route parameters (for example, prefix, prefix lengths, and BGP attributes).

  • Scalability—Junos OS routing tables have been designed to hold all the routes in current networks with ample capacity for expansion. Additionally, Junos OS can efficiently support large numbers of interfaces and virtual circuits.

  • Management interface—Different levels of system management tools are provided, including the Junos OS CLI, the Junos XML management protocol, the craft interface, and SNMP.

  • Storage and change management—Configuration files, system images, and microcode can be held and maintained in primary and secondary storage systems, permitting local or remote upgrades.

  • Monitoring efficiency and flexibility—The PTX3000 supports functions such as alarm handling and packet counting on every port without degrading packet-forwarding performance.

  • Chassis management functions:

    • Detection of the insertion or removal of PTX3000 components

    • Controlling power and reset for the other PTX3000 components

    • Monitoring and controlling fan speed

    • Monitoring system status

  • Providing Centralized Clock Generator (CCG) ports and a 19.44-MHz Stratum 3 clock signal for the Ethernet network interfaces on the PTX3000

  • Secure Boot— Secure Boot implementation in the RCB is based on the UEFI 2.4 standard. The BIOS is hardened and serves as a core root of trust. The BIOS updates, the bootloader, and the kernel are cryptographically protected. No action is required to implement Secure Boot.

Routing and Control Board Components

Each RCB consists of the following components:

  • CPU—Runs Junos OS to maintain the routing tables and routing protocols.

  • DRAM—Provides storage for the routing and forwarding tables and for other Routing Engine processes.

  • EEPROM—Stores the serial number of the RCB.

  • CCG—Provides clock synchronization signal and 19.44-MHz Stratum 3 clock.

  • 10-Gigabit Ethernet and PCIe switches—Provide control plane connectivity to the other components.

  • Field-programmable gate arrays (FPGAs)—Perform multiplexing of clock sources as well as other control and management functions.

  • Interfaces for management access—Provide information about RCB status to the external management devices (console, laptop, or terminal server) connected to the management ports on the RCB.

    • 5/10 MHz GPS ports labeled 0 and 1.

    • Building integrated timing supply (BITS) ports labeled BITS B and BITS A. Two small LEDs on each port indicate link status and faults.

  • Three RJ-45 management ports for connecting the RCB to external management devices. From these management devices, you can use the CLI to configure and manage the PTX3000. Each RCB includes the following management ports:

    • AUX— One copper 9600-baud port for connecting the RCB to a laptop, modem, or other auxiliary device through a copper cable with RJ-45 connectors.

    • CON—One copper 9600-baud port for connecting the RCB to a system console through a copper cable with RJ-45 connectors.

    • MGMT—10/100-Mbps/1-Gbps Ethernet port for connecting to an out-of-band management network. This port connects the RCB through a copper 10/100/1000 BASE-T Ethernet connection to a management LAN (or any other device that plugs into an Ethernet connection) for management of the PTX3000. The port uses an autosensing RJ-45 connector to support 10-Mbps, 100-Mbps, or 1-Gbps connections. Two small LEDs indicate link speed and activity on the port.

      Note:

      If there are two RCBs installed, connect both to your external management network.

PTX3000 Routing and Control Board Companion Card Description

Routing and Control Board Companion Card Slots

You can install up to two Routing and Control Board (RCB) companion cards (RCB-CC) in the PTX3000. RCB companion cards install in the RE0 and RE1 slots to the left of each RCB. The RCB companion cards do not function if an RCB is not present in its adjacent slot.

Routing and Control Board Companion Card Function

The RCB companion card provides passive connectivity across the backplane between the RCBs. The companion card must be installed only in the RE slot when an RCB is installed in the router, and no other Routing Engine must be installed in that slot.

Note:

In a redundant host subsystem, when you are performing the primary-role switchover from one Routing Engine to another Routing Engine, you must install both the RCB companion cards.

Note:

If you are using only a single RCB in the PTX3000 (that is, in a nonredundant host subsystem), with no backup RCB, you do not need to install an RCB companion card. However, to ensure proper cooling, the Routing Engine slot must be populated with either the RCB-CC or a Routing Engine blank.

Routing and Control Board Companion Card Components

Each RCB companion card has Ethernet cross-links that provide passive connectivity between the RCBs.

Figure 9 shows the components of the RCB companion card. The faceplate has only the LED and ejector handles.
