Figure 1: M5 and M10 Routers

The M5 and M10 routers include the router-specific Forwarding Engine Board (FEB) component that provides route lookup, filtering, and sampling, as well as switching to the destination PIC. The FEB performs the function of the Flexible PIC Concentrators

Chapter 1: M Series Multiservice Edge Routers

(FPCs) on other M Series routers. The FEB contains the Internet Processor II application-specific integrated circuit (ASIC),two distributedBuffer ManagerASICs, and two I/O Manager ASICs, and is responsible for making forwarding decisions, distributing packets throughout memory, and forwarding notification of outgoing packets.

The M5 and M10 routers provide a wide range of high-performance interfaces from T1 and E1 through OC12c/STM4 (for the M5 router) or OC48c/STM16 (for the M10 router). PICs between the tworouters are interchangeable.For moreinformation aboutsupported PICs and FPCs for each M Series router type, see the appropriate PIC installation guide.

The M5 and M10 router Internet processor II ASIC forwards packets at a throughput rate of up to 5 Gbps for the M5 router and up to 10 plus Gbps for the M10 router. The ASIC technology provides such packet processing as rate limiting, filtering, and sampling of IP services.

M7i Multiservice Edge Router Overview

The M7i Multiservice Edge Router provides security and performance in small to medium Points of Presence (PoPs), as well as a carrier-class customer premise equipment (CPE) solution for managed services and campus border router applications. (See Figure 2 on

page 6.)

Figure 2: M7i Router

The M7i router includes the Compact Forwarding Engine Board (CFEB) which provides route lookup, filtering, and switching on incoming data packets, then directs outbound packets to the appropriate interface for transmission to the network. It can process 16 million packets per second (Mpps). The CFEB communicates with the Routing Engine using adedicated100-Mbps link that transfers routing table data fromthe RoutingEngine to the forwarding table. The link is also used to transfer routing link-state updates and other packets destined for the router from the CFEB to the Routing Engine.

A built-in tunnel interface encapsulates arbitrary packets inside a transport protocol, providing a private, secure path through an otherwise public network. The built-in tunnel interface on the CFEB is configured the same way as a PIC. For information about configuring the built-in tunnel interface, seethe Junos OS Services Interfaces Configuration Guide.

The Adaptive Services PIC-Integrated (ASP-I) is an optional component on the CFEB which performs one or more services on traffic—Stateful firewall, Network Address Translation (NAT) or intrusion detection services (IDS)—before it reaches its destination.

In addition to accommodating up to four PICs, the M7i router includes a built-in Fixed Interface Card (FIC) that provides two Fast Ethernet ports or one Gigabit Ethernet port, depending on which FIC or which model was ordered. For more information about Fast Ethernet and Gigabit Ethernet interfaces, see the M7i Multiservice Edge Router PIC Guide.

Chapter 1: M Series Multiservice Edge Routers

The M7i router supports various PICs, including ATM, channelized, Ethernet, IP services, and SONET/SDH interfaces. For more information about supported PICs, see the M7i Multiservice Edge Router PIC Guide.

The M7i router provides a maximum aggregate throughput of 8.4 gigabits per second (Gbps). Control operations in the router are perform Control operations in the router are performed by the Routing Engine, which runs the Junos OS operating system (OS) to handle routing protocols, traffic engineering, policy,policing, monitoring,and configuration management.

M40e Multiservice Edge Router Overview

The M40e router provides a dense, highly redundant platform primarily for dedicated access aggregation at the edge as well as for mid-size core IP networks. The M40e router supports Junos OS which provides router configuration and monitoring. (See Figure 6 on

page 15 .)

Figure 6: M40e Router

The M40e router shares the same chassis and many of the same components as the M160 Internet router. It accepts both AC and DC power supplies. The M40e router can have up to two Switching and ForwardingModules (SFMs).The SFMscontain the Internet Processor II application-specific integrated circuit (ASIC) and two Distributed Buffer Manager ASICs, andmake forwardingdecisions, distribute packets throughout memory, and forward notification of outgoing packets.

The M40e router includes the host module that constructs routing tables, performs system management functions, and generates the SONET/SDH clock signal for SONET/SDH interfaces. The host module contains the Routing Engine and the MiscellaneousControl Subsystem(MCS). The Routing Engine managesrouting protocols and maintains the routing tables. For a host module to function, both of these components must be installed and operational.

The M40e router houses three types of Flexible PIC Concentrators (FPCs): one to accommodate M20 and M40 PICs, and two to accommodate hot-swappable M160 router PICs. The Type 1 FPCs for the M40e and M160 routers are interchangeable.

M320 Multiservice Edge Router Overview

The M320 Multiservice Edge Router is a high-density edge aggregation, routing, and service creation platform that builds on Juniper Networks service-built edge design. Constructed with separations between the control plane, forwarding plane, and services plane, the router supports multiple services on a single platform. The Junos OS runs on a control subsystem with dedicated hardware, ensuring that control functions are performed without affecting theforwardingsubsystem. Forwarding andpacket processing operations in the router are performed by dedicated programmable ASICs that enable the router to achieve data forwarding rates that match current fiber-optic capacity. This design eliminates processing and traffic bottlenecks, permitting the router to achieve high performance. The router can be deployed in core, peering, and data center applications, but is optimized for dense edge aggregation and service creation. TheM320 router can provide a single point of edge aggregation for thousands of customers over any access type, including ATM, Frame Relay, Ethernet, and TDM, at any speed from DS0 up to OC192/STM64 and 10-Gigabit Ethernet. (See Figure 11 on page 24.)

Figure 11: M320 Router

The M320 router includes Switch Interface Boards (SIBs) that provide the switching function to the destination Flexible PIC Concentrator (FPC) at a total of 385 million packets per second (Mpps) of forwarding. The host subsystem, which consists of the Routing Engine and Control Board, provides the routingand system management functions of the router.

The router supportsup to eightFPCs providing SONET/SDHOC-48/STM16,SONET/SDH OC192/STM64, and160-Gigabit Ethernet media. The router supports three types of FPCs: FPC1 for hot-swappable M40e PICs, FPC2 for hot-swappable M160 PICs, and FPC3 for 10-Gbps T Series PICs. For more information about supported PICs, see the M320 Multiservice Edge Router PIC Guide.

The M320 router provides a maximum aggregate throughput of 320 gigabits per second (GBps) full duplex. The Junos operating system (OS) runs on a control subsystem with dedicatedhardware, ensuring that control functions are performed without affectingthe forwarding subsystem. Forwarding and packet processing operations in the router are performed by dedicated programmable ASICs that enable the router to achieve data forwarding rates the match current fiber-optic capacity.

The T1600 router supports the following types of Flexible PIC Concentrators (FPCs):

•

FPC1 is rated at 2 Gbps and 4 Gbps full duplex for the T320 and T640/T1600 routers, respectively.

•

FPC2 is rated at 8 Gbps and 16 Gbpsfull duplex for the T320 and T640/T1600 routers, respectively.

•

FPC3 is rated at 20 and 40 Gbps full duplex for the T320 and T640/T1600 routers, respectively.

•

FPC4 is rated at 40 Gbps full duplex for the T640/T1600 routers.

•

The T1600 Type-4 FPC is rated at 100 Gbps full duplex and supports two Type 4 PICS.

Chapter 2: T Series Core Routers

The T1600 router can operate with any combination of FPC1s, FPC2s, FPC3s, and FPC4s installed. Each FPC contains one or two Packet Forwarding Engines. The Packet Forwarding Engine consists of Layer 2/Layer 3 Packet Processing application-specific integrated circuits (ASICs), Switch Interface ASICs, T Series Internet Processor ASICs, and a memory subsystem (MMB) which includes the Queuing and Memory Interface ASICs. The Packet Forwarding Engine receives incoming packets from the PICs installed on the FPC and forwards them through the switch planes to the appropriate destination port. Each FPC contains data memory, which is managed by the Queuing and Memory Interface ASICs. Each FPC3 and each T1600 FPC4 has two Packet Forwarding Engines, and each FPC2 and each T640 FPC3 has one Packet Forwarding Engine.

PICs provide the physical connection to various network media types, receiving incoming packets from the network and transmitting outgoing packets to the network. PICs for the T1600 router currently support the following network media types: Gigabit Ethernet, SONET/SDH OC12c/STM4,OC48c/STM16, OC192c/STM64, andOC768c/STM256. The router also supports MultiServices PICs and Tunnel Service PICs. You can install up to four PICs into the slots in each FPC. For more information on PICs used in the router, see the T1600 Core Router PIC Guide.

The Switch Interface Boards (SIBs) provide the switching function to the destination FPC. The SIBs create the switch fabric for the router, providing up to a total of 1.92 billion Mpps of forwarding. Five SIBs are installed in the router.

Each Control Board works with an adjacent Routing Engine to provide control and monitoring functions for the router. These functions include determining Routing Engine mastership;controlling power,reset, andSONET clocking for theother router components; monitoring and controlling fan speed;and monitoringsystem status using I²C controllers.

ASICs are a definitive part of the router design; these ASICs enable the router to achieve data rates that match current fiber-optic capacity.

TX Matrix Router Overview

The Juniper Networks TX Matrix router is the centralized switch fabric of the routing matrix, which is a terabit routing system interconnecting up to four T640 Core Routers to deliver up to 2.56 terabits per second (Tbps) of subscriber switching capacity. The routing matrix multichassis architecture provides scalable growth for aggregation and core services for voice, video, and data networks. It provides a flexible and cost-effective means to simplify large point-of-presence (POP) and central office environments. The routing matrix delivers high-availability services from tunnel services, ATM, DS3, OC3/STM1, OC12/STM4, Gigabit Ethernet, 10-Gigabit Ethernet, OC48/STM16, OC192/STM64, and other high-speed interfaces. The routing matrix leverages the intelligent virtual services capabilities of Junos OS, which enable you to create multiple application-specific logical networks over a single physical topology. This gives you the ability to virtually separate traffic types that require unique network attributes—such as ATM or high-priority voice over IP (VoIP) and third-generation (3G) mobile traffic—from bulk transit IP traffic.

The TX Matrix router architecture cleanly separates control operations from packet forwarding operations. This design eliminates processing and traffic bottlenecks, permitting the TX Matrix router toachieve terabit performance levels. Control operations in the TX Matrix router are performed by the host subsystem, which runs Junos OS to handle traffic engineeringand configurationmanagement. High-availability, interchassis communicationsare provided by an Ethernet LAN that interconnects the host subsystems in the TX Matrix router and the T640 routers. The TX Matrix router is a modular, rack-mountable system. One TX Matrix router can be installed in one standard 19-in. wide, 78-in. high, EIA telco rack. The TX Matrix router supports the Junos OS, which provides router configuration and monitoring. (See Figure 17 on page 40 and Figure 18 on

page 41.)

Chapter 2: T Series Core Routers

The routing matrix has two main architectural components, the control plane and the forwarding plane:

•

The control plane in the routing matrix is formed by the connection of the host subsystems—TX-CBs in the TX Matrix router and T-CBs in the T640 routers —and the Routing Engines.

•

The forwarding plane in the routing matrix is formed by the switch fabric—TX-SIBs in the TX Matrix router and T640-SIBs in the T640 routers—and the Packet Forwarding Engines.

TX Matrix Plus Router Overview

The TXMatrix Plus router is the central switching and routing element that interconnects up to four T1600 chassis into a single routing entity with 32 slots and a sustainable throughput rate of up to 6.4 Tbps (7.68 billion pps). With the TX Matrix Plus router, operators can build systems containing up to four line-card chassis for a total of up to 320/640 10GbE (line rate/oversubscribed) ports, 64 40 Gbps ports, or 32 100GbE ports. Using the virtualization capabilities of the JCS Control System, this available resource can be partitioned into aggregation or edge routing, or into the support of virtual service networks for advanced partitioned services such as video, mobile, and all corporate traffic. (See Figure 19 on page 44 and Figure 20 on page 45.)

The routing matrix multichassis architecture provides scalable growth for aggregation and core services for voice, video, and data networks. It provides a flexible and cost-effective means to simplify large point-of-presence (POP) and central office environments. The routing matrix delivers high availability services from tunnel services, ATM, DS3, OC3/STM1, OC12/STM4,Gigabit Ethernet, 10-Gigabit Ethernet, OC48/STM16, OC192/STM64, and other high-speed interfaces.

You should routinely monitor the status of all Juniper Networks routers running on the network.

M Series and T Series Routers Monitoring and Troubleshooting Guide

The Simple Network ManagementProtocol (SNMP) networkmanager software running on a network management system (NMS) in the network operations center (NOC) discovers, polls, and exchanges network management information with the Junos OS SNMP agent running on Juniper Networks routers. The SNMP network manager software collects information about router connectivity, operation, and events.

The SNMP agent responds to requests for information and controls access to its Management Information Bases (MIBs). The MIBs define allobjects that can be managed on the router via SNMP. The Junos OS chassis MIB provides environmental monitoring information on the router and its components. MIB objects represent each component and the status of the components.

A trap is generated and reportedto theSNMP manager softwarewhen a significant event occurs on the router, such as an error or failure. When a trap occurs, you can log in to that router to get specific operational status information about the problem; for more information, see “Check the Router Component Status” on page 60 and “Gather

Component Alarm Information” on page 67. Verify the problem and fix it if possible; for

more information, see “Verify the ComponentProblem”on page 114 and “Fix theProblem”

on page 114.If youcannot verifyor fix the problem,contact theJuniper Networks Technical

Assistance Center (JTAC) for more advanced analysis and troubleshooting, and return the component once failure is verified; for more information, see “Contact JTAC” on

page 115 and “Return the Failed Component” on page 116.

Chapter 3: Method and Tools for Monitoring Router Components

Table 17: Basic Tools for Monitoring Router Components (continued)

Router Component Monitor Tool

Purpose

Junos OS

The primary means of accessing and controlling the Junos OS is the CLI.

For M5, M10, M20, and M40 routers, the router provides three ports on the craft interface for connecting external management devices to the Routing Engine and hence to the Junos OS.

For M40e, M160, M320, T320, T640, T1600, TX Matrix, and TX Matrix Plus routers, the management ports are located on the Connector Interface Panel (CIP).

For M7i, M10i, and M120 routers, the management ports are located on the Routing Engine.

The management ports include the following:

•

Ethernet—Used to connect the Routing Engine to a management LAN (or any other device that plugs into an Ethernet connection) for out-of-band management of the router. The Ethernet port can be 10 or 100 Mbps and uses an autosensing RJ-45 connector. The Ethernet management port has two LEDs, which indicate the type of connection in use. A yellow LED lights when a 10-Mbps connection is active, and a green LEDlights whena 100-Mbps connection is active.

•

Console—Used to connect a system console to the Routing Engine with an RS-232 serial cable.

•

Auxiliary—Used to connect a laptop computer or modem to the Routing Engine with an RS-232 cable.

Junos OS commands

The Junos OS CLI has two modes: operational and configuration.

NOTE: You only need to type cli if you log in to the router as

root. Otherwise, theCLI shouldbe already inoperationalmode.

•

In operational mode, you monitor and troubleshoot the software, network connectivity, and router by entering commands. To enter operational mode, log in to the router and type cli at the command prompt.

•

In configuration mode, you configure the Junos OS that controls the router. To enter configuration mode:

a. Log in to the router.

b. Start the CLI by typing cli at the command prompt.

c. Type edit at the command prompt.

For more information about commands, see “Checklist for

Monitoring the CIP” on page 479.
