READ THIS END USER LICENSE AGREEMENT ("AGREEMENT") BEFORE DOWNLOADING, INSTALLING, OR USING THE SOFTWARE. BY

DOWNLOADING, INSTALLING, OR USING THE SOFTWARE OR OTHERWISE EXPRESSING YOUR AGREEMENT TO THE TERMS CONTAINED HEREIN, YOU (AS CUSTOMER OR IF YOU ARE NOT THE CUSTOMER, AS A REPRESENTATIVE/AGENT AUTHORIZED TO BIND THE CUSTOMER) CONSENT TO BE BOUND BY THIS AGREEMENT. IF YOU DO NOT OR CANNOT AGREE TO THE TERMS CONTAINED HEREIN, THEN (A) DO NOT DOWNLOAD, INSTALL, OR USE THE SOFTWARE, AND (B) YOU MAY CONTACT JUNIPER NETWORKS REGARDING LICENSE TERMS.

1. The Parties. The parties to this Agreement are Juniper Networks, Inc. and its subsidiaries (collectively "Juniper"), and the person or organization that originally purchased from Juniper or an authorized Juniper reseller the applicable license(s) for use of the Software ("Customer") (collectively, the "Parties").

2. The Software. In this Agreement, "Software" means the program modules and features of the Juniper or Juniper-supplied software, and updates and releases of such software, for which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller.

! iii

3. License Grant. Subject to payment of the applicable fees and the limitations and restrictions set forth herein, Juniper grants to Customer a non-exclusive and non-transferable license, without right to sublicense, to use the Software, in executable form only, subject to the following use restrictions:

a. Customer shall use the Software solely as embedded in, and for execution on, Juniper equipment originally purchased by Customer from Juniper or an authorized Juniper reseller, unless the applicable Juniper documentation expressly permits installation on non-Juniper equipment.

b. Customer shall use the Software on a single hardware chassis having a single processing unit, or as many chassis or processing units for which Customer has paid the applicable license fees.

c. Other Juniper documentation for the Software (such as product purchase documents, documents accompanying the product, the Software user manual(s), Juniper's website for the Software, or messages displayed by the Software) may specify limits to Customer's use of the Software. Such limits may restrict use to a maximum number of seats, concurrent users, sessions, subscribers, nodes, or transactions, or require the purchase of separate licenses to use particular features, functionalities, or capabilities, or provide temporal or geographical limits. Customer's use of the Software shall be subject to all such limitations and purchase of all applicable licenses.

The foregoing license is not transferable or assignable by Customer. No license is granted herein to any user who did not originally purchase the applicable license(s) for the Software from Juniper or an authorized Juniper reseller.

4. Use Prohibitions. Notwithstanding the foregoing, the license provided herein does not permit the Customer to, and Customer agrees not to and shall not: (a) modify, unbundle, reverse engineer, or create derivative works based on the Software; (b) make unauthorized copies of the Software (except as necessary for backup purposes); (c) rent, transfer, or grant any rights in and to any copy of the Software, in any form, to any third party; (d) remove any proprietary notices, labels, or marks on or in any copy of the Software; (e) distribute any copy of the Software to any third party, including as may be embedded in Juniper equipment sold in the secondhand market; (f) use any 'locked' or key-restricted feature, function, or capability without first purchasing the applicable license(s) and obtaining a valid key from Juniper, even if such feature, function, or capability is enabled without a key; (g) distribute any key for the Software provided by Juniper to any third party; (h) use the Software in any manner that extends or is broader than the uses purchased by Customer from Juniper or an authorized Juniper reseller; (i) use the Software on non-Juniper equipment where the Juniper documentation does not expressly permit installation on non-Juniper equipment; (j) use the Software (or make it available for use) on Juniper equipment that the Customer did not originally purchase from Juniper or an authorized Juniper reseller; or (k) use the Software in any manner other than as expressly provided herein.

5. Audit. Customer shall maintain accurate records as necessary to verify compliance with this Agreement. Upon request by Juniper, Customer shall furnish such records to Juniper and certify its compliance with this Agreement.

6. Confidentiality. The Parties agree that aspects of the Software and associated documentation are the confidential property of Juniper. As such, Customer shall exercise all reasonable commercial efforts to maintain the Software and associated documentation in confidence, which at a minimum includes restricting access to the Software to Customer employees and contractors having a need to use the Software.

7. Ownership. Juniper and Juniper's licensors, respectively, retain ownership of all right, title, and interest (including copyright) in and to the Software, associated documentation, and all copies of the Software. Nothing in this Agreement constitutes a transfer or conveyance of any right, title, or interest in the Software or associated documentation, or a sale of the Software, associated documentation, or copies of the Software.

8. Warranty, Limitation of Liability, Disclaimer of Warranty. If the Software is distributed on physical media (such as CD), Juniper warrants for 90 days from delivery that the media on which the Software is delivered will be free of defects in material and workmanship under normal use. This limited warranty extends only to the Customer. Except as may be expressly provided in separate documentation from Juniper, no other warranties apply to the Software, and the Software is otherwise provided AS IS. Customer assumes all risks arising from use of the Software. Customer's sole remedy and Juniper's entire liability under this limited warranty is that Juniper, at its option, will repair or replace the media containing the Software, or provide a refund, provided that Customer makes a proper warranty claim to Juniper, in writing, within the warranty period. Nothing in this Agreem

ent shall give rise to any obligation to support the Software. Any such support shall be governed by a separate, written agreement. To the maximum extent permitted by law, Juniper shall not be liable for any liability for lost profits, loss of data or costs or procurement of substitute goods or services, or for any special, indirect, or consequential damages arising out of this Agreement, the Software, or any Juniper or Juniper-supplied software. In no event shall Juniper be liable for damages arising from unauthorized or improper use of any Juniper or Juniper-supplied software.

EXCEPT AS EXPRESSLY PROVIDED HEREIN OR IN SEPARATE DOCUMENTATION PROVIDED FROM JUNIPER AND TO THE EXTENT PERMITTED BY LAW, JUNIPER DISCLAIMS ANY AND ALL WARRANTIES IN AND TO THE SOFTWARE (WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE), INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NONINFRINGEMENT. IN NO EVENT DOES JUNIPER WARRANT THAT THE SOFTWARE, OR ANY EQUIPMENT OR NETWORK RUNNING THE SOFTWARE, WILL OPERATE WITHOUT ERROR OR INTERRUPTION, OR WILL BE FREE OF VULNERABILITY TO INTRUSION OR ATTACK.

9. Termination. Any breach of this Agreement or failure by Customer to pay any applicable fees due shall result in automatic termination of the license granted herein. Upon such termination, Customer shall destroy or return to Juniper all copies of the Software and related documentation in Customer's possession or control.

10. Taxes. All license fees for the Software are exclusive of taxes, withholdings, duties, or levies (collectively "Taxes"). Customer shall be responsible for paying Taxes arising from the purchase of the license, or importation or use of the Software.

11. Export. Customer agrees to comply with all applicable export laws and restrictions and regulations of any United States and any applicable foreign agency or authority, and not to export or re-export the Software or any direct product thereof in violation of any such restrictions, laws or regulations, or without all necessary approvals. Customer shall be liable for any such violations. The version of the Software supplied to you may contain encryption or other capabilities restricting your ability to export the Software without an export license.

12. Commercial Computer Software. The Software is "commercial computer software" and is provided with restricted rights. Use, duplication, or disclosure by the United States government is subject to restrictions set forth in this Agreement and as provided in DFARS 227.7201 through 227.7202-4, FAR 12.212, FAR 27.405(b)(2), FAR 52.227-19, or FAR 52.227-14(ALT III) as applicable.

13. Miscellaneous. This Agreement shall be governed by the laws of the State of California without reference to its conflicts of laws principles. For any disputes arising under this Agreement, the Parties hereby consent to the personal and exclusive jurisdiction of, and venue in, the state and federal courts within Santa Clara County, California. This Agreement constitutes the entire and sole agreement between Juniper and the Customer with respect to the Software, and supersedes all prior and contemporaneous agreements relating to the Software, whether oral or written (including any inconsistent terms contained in a purchase order), except that the terms of a separate written agreement executed by an authorized Juniper representative and Customer shall govern to the extent such terms are inconsistent or conflict with terms contained herein. No modification to this Agreement nor any waiver of any rights hereunder shall be effective unless expressly assented to in writing by the party to be charged. If any portion of this Agreement is held invalid, the Parties agree that such invalidity shall not affect the validity of the remainder of this Agreement.

4 ! M5 and M10 Router Components

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 Physical Interface Card (PIC). The FEB performs the function of the Flexible PIC Concentrators (FPCs) on other M-series routers. The FEB contains the Internet Processor II application-specific integrated circuit (ASIC), two distributed Buffer Manager ASICs, 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 two routers are interchangeable. For more information about supported 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.

Chapter 1: M5 and M10 Internet Router Overview

Field-replaceable units (FRUs) are router components that can be replaced at the customer site. Replacing FRUs requires minimal router downtime. There are three types of FRUs:

! Hot-removable and hot-insertable—You can remove and replace the

component without powering down the router or interrupting the routing functions.

! Hot-pluggable—You can remove the component without powering down the

router, but routing functions are interrupted until the replacement is installed.

! Requires router shutdown—You must power down the router before removing

the component.

M7i Internet Router Overview

The M7i Internet 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.)

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 a dedicated 100-Mbps link that transfers routing table data from the Routing Engine 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, see the JUNOS 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.

For more information about Fast Ethernet and Gigabit Ethernet interfaces, see the M7i Internet Router PIC Guide.

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 Internet 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 JUNOS software to handle routing protocols, traffic engineering, policy, policing, monitoring, and configuration management.

M10i Internet Router Overview

The M10i Internet router provides high-speed interfaces for medium and large networks and network applications, such as those supported by Internet service providers (ISPs). (See Figure 3.)

Figure 3: M10i Router

The M10i router includes the router-specific Compact Forwarding Engine Board (CFEB) which performs route lookup, filtering, and switching on incoming data packets, then directs outbound packets to the appropriate Flexible PIC Concentrator (FPC) for transmission to the network. It can process 16 million packets per second (Mpps).

A High-Availability Chassis Manager (HCM) works with its companion Routing Engine to provide control and monitoring functions for router components. The HCM also displays alarm status and takes Physical Interface Cards (PICs) online and offline.

On the M10i router, built-in FPCs house the PICs that connect the router to network media. The router supports up to eight PICs, including ATM, Channelized, Gigabit Ethernet, IP Services, and SONET/SDH interfaces. For more information on PICs, see the M10i Internet Router PIC Guide.

Some PICs, such as Gigabit Ethernet PICs, accept small form-factor pluggable tranceivers (SFPs), which are fiber-optic transceivers that can be removed from the PIC.

The M20 router includes the router-specific System and Switch Board (SSB) that provides route lookup, filtering, and sampling to the destination Flexible PIC Concentrator (FPC). The SSB contains both the Internet Processor II application-specific integrated circuit (ASIC) and the Distributed Buffer Manager ASIC, and makes forwarding decisions, distributes data cells throughout memory, processes exception and control packets, monitors system components, and controls FPC resets. You can install up to two SSBs.

Physical Interface Cards (PICs) are available in supported media types, including Asynchronous Transfer Mode (ATM), Channelized, DS3, E1, E3, T1, Ethernet, SONET/SDH, and IP services. The M20 and M40 router FPCs and PICs are interchangeable, and most of the PICs can also be used in the M40e Internet router. For more information about supported PICs and FPCs for each M-series router type, see the appropriate PIC installation guide.

! FPC2—Supports PICs that are also used in the FPC2 of a Juniper Networks

M-series router and T640 Internet routing node

! FPC3—Supports higher-speed PICs that are also used in the FPC3 of a Juniper

Networks T640 routing node

The router can operate with any combination of FPCs installed.

Forwarding operations in the router are performed by the Packet Forwarding Engines. Each FPC contains one Packet Forwarding Engine. The Packet Forwarding Engines receive incoming packets from the PICs installed on the FPC and forward them through the switch planes to the appropriate destination port. Each FPC contains data memory, which is managed by the Queuing and Memory Interface application-specific integrate circuits (ASICs).

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 T320 router currently support the following network media types: ATM, ATM2, Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, SONET/SDH OC3c/STM1, SONET/SDH OC12c/STM4, OC48c/STM16, OC192c/STM64, and Tunnel services. For more information on PICs used in the router, see the T320 Internet Router PIC Guide.

The T320 router supports two DC power supplies, which share the load evenly.

Three 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 320 million packets per second (Mpps) of forwarding.

Routing and system management functions of the router are performed by the host subsystem. The host subsystem consists of the Routing Engine and the Control Board.

The Routing Engine maintains the routing tables used by the router and controls the routing protocols that run on the router. Each Control Board works with an adjacent Routing Engine to provide control and monitoring functions for the router. These include determining Routing Engine mastership, controlling power, reset and SONET clocking for the other router components, monitoring and controlling fan speed, and monitoring system status using I

C controllers.

T640 Internet Routing Node Overview

The T640 Internet routing node provides 40G capable platform, delivering 640 Gigabits per second (Gbps) of capacity and up to 770 million packets per second (Mpps) of throughput and supports 32 10-Gbps (OC192c/STM64 and 10-Gigabit Ethernet) ports, as well as OC48c/STM16. Gigabit Ethernet, SONET/SDH, and other high-speed interfaces for large core networks and network applications, such as those supported by Internet service providers (ISPs). It provides a cost-effective migration path to an Multiprotocol Label Switching (MPLS) infrastructure. The T640 routing node supports the JUNOS software which provides router configuration and monitoring. (See Figure 10 on page 40.)

JUNOS Internet Software Network Operations Guide: Hardware

40 !

Figure 10: T640 Routing Node

In a standalone configuration, the T640 routing node’s maximum aggregate throughput is 320 Gbps, full duplex.

The T640 routing node supports two types of Flexible PIC Concentrators (FPCs):

! FPC2—Rated at 10 Gbps full duplex; supports PICs that are also used in the

M160 router.

! FPC3—Rated at 40 Gbps full duplex; supports higher-speed PICs.

The T640 routing node can operate with any combination of FPC2s and FPC3s 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 has two Packet Forwarding Engines, and each FPC2 has one Packet Forwarding Engine.

Chapter 10: T640 Internet Routing Node Overview

Physical Interface Cards (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 T640 routing node currently support the following network media types: Gigabit Ethernet, SONET/SDH OC12c/STM4, OC48c/STM16, OC192c/STM64, and Tunnel Services. You can install up to four PICs into the slots in each FPC. For more information on PICs used in the routing node, see the T640 Internet Routing Node PIC Guide.

The Switch Interface Boards (SIBs) provide the switching function to the destination FPC. The SIBs create the switch fabric for the routing node, providing up to a total of 640 million Mpps of forwarding. Five SIBs are installed in the routing node.

The host subsystem provides the routing and system management functions of the routing node. The host subsystem consists of the Routing Engine and the Control Board. The Routing Engine maintains the routing tables used by the routing node and controls the routing protocols that run on the routing node.

Each Control Board works with an adjacent Routing Engine to provide control and monitoring functions for the routing node. These include determining Routing Engine mastership; controlling power, reset, and SONET clocking for the other routing node components; monitoring and controlling fan speed; and monitoring system status using I

C 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.

42 ! Monitoring T640 Routing Node Components

Field-replaceable units (FRUs) are router components that can be replaced at the customer site. Replacing FRUs requires minimal router downtime. There are three types of FRUs:

! Hot-removable and hot-insertable—You can remove and replace the

component without powering down the router or interrupting the routing functions.

! Hot-pluggable—You can remove the component without powering down the

router, but routing functions are interrupted until the replacement is installed.

! Requires router shutdown—You must power down the router before removing

the component.

JUNOS Internet Software Network Operations Guide: Hardware

48 ! Basic Router Component Monitoring Method

The Simple Network Management Protocol (SNMP) network manager software running on a network management system (NMS) in the network operations center (NOC) discovers, polls, and exchanges network management information with the JUNOS software 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 all objects that can be managed on the router via SNMP. The JUNOS software 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 reported to the SNMP manager software when 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 29 and “Gather Component Alarm Information” on page 33. Verify the problem and fix it if possible; for more information, see “Verify the Component Problem” on page 34 and “Fix the Problem” on page 35. If you cannot verify or fix the problem, contact the Juniper 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 35 and “Return the Failed Component” on page 36.

Basic Router Component Monitoring Tools

Table 13 lists and describes the purposes of the basic tools you use to monitor router hardware.

Table 13: Basic Tools for Monitoring Router Components

Router Component Monitor Tool

Purpose

JUNOS SNMP Agent, MIBs, and traps

! The JUNOS SNMP agent runs on Juniper Networks routers,

exchanging network management information with SNMP manager software running on an NMS or host. The SNMP manager collects information about network connectivity, activity, and events by polling the router. The agent responds to requests for information and actions from the manager.

! The SNMP agent also controls access to the agent’s MIBs.

The JUNOS software chassis MIB represents each component and the status of the components.

! The agent sends a trap to the SNMP manager software

when an event occurs on the router. A trap reports significant events occurring on a network device; for example, most often errors or failures.

JUNOS software The primary means of accessing and controlling the JUNOS

software is the command-line interface (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 software.

For M40e, M160, M320, and T320 routers, and the T640 routing node, the management ports are located on the Connector Interface Panel (CIP).

For M7i and M10i 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 LED lights when a 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.

50 ! Basic Router Component Monitoring Tools

JUNOS software CLI commands The JUNOS software CLI has two modes: operational and

configuration. Note: You only need to type

cli if you log in to the router as

root. Otherwise, the CLI should be already in operational mode.

! In operational mode, you monitor and troubleshoot the

software, network connectivity, and router by entering CLI commands. To enter operational mode, log in to the router and type

cli at the command prompt.

! In configuration mode, you configure the JUNOS software

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.

Display Detailed Component Environmental Information

(For M7i, M10i, M40e, M160, M320, and T320 routers and T640 routing node) You can display detailed environmental status information about certain router components.

Action To display detailed environmental status information about a component, use the

following CLI command:

user@host> show chassis environment component-name

The command output displays the temperature of the air passing by the component, in degrees Centigrade and Fahrenheit. It also displays whether the fans and/or blowers are at normal or high speed.

Table 18 lists the operational mode CLI commands for each router component for which you can display more detailed information.

Display Detailed Component Operational Information

You can display detailed operational information about certain router components. This feature is available on all routing platforms except the M5/M10, M20, and M40 routing platforms.

Action To display detailed operational information about a component, use the following

CLI command:

user@host> show chassis component-name

The command output displays the temperature of the air passing by the component, in degrees Centigrade and Fahrenheit. It displays the total percentage of CPU, interrupt, heap space, and buffer space being used by the component processor, including the total DRAM available to the component processor. The command output displays the time when the component started running and how long the component has been running. A short uptime can indicate a problem with the component.

Table 19 lists the components for which you can display more detailed operational status information.

Display the Current Router Alarms

Action To display the current router component alarms, use the following CLI command:

user@host> show chassis alarms

The command output displays the number of alarms currently active, the time when the alarm began, the severity level, and an alarm description. Note the date and time of an alarm so that you can correlate it with error messages in the

messages system log file.

Various conditions related to the chassis components trigger yellow and red alarms. You cannot configure these conditions. Table 20 through Table 27 list the alarms that the chassis components can generate.

Table 20 lists the alarms that the chassis components can generate on an M5 or M10 router.
