END USER LICENSE AGREEMENT
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 (i) Juniper Networks, Inc. (if the Customers principal office is located in the Americas) or Juniper Networks (Cayman) Limited (if the Customers principal office is located outside the Americas) (such applicable entity being referred to herein as Juniper), and (ii) 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, for which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller, or which was embedded by Juniper in equipment which Customer purchased from Juniper or an authorized Juniper reseller. Software also includes updates, upgrades and new releases of such software. Embedded Software means Software which Juniper has embedded in or loaded onto the Juniper equipment and any updates, upgrades, additions or replacements which are subsequently embedded in or loaded onto the equipment.
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 Embedded Software solely as embedded in, and for execution on, Juniper equipment originally purchased by Customer from Juniper or an authorized Juniper reseller.
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; provided, however, with respect to the Steel-Belted Radius or Odyssey Access Client software only, Customer shall use such Software on a single computer containing a single physical random access memory space and containing any number of processors. Use of the Steel-Belted Radius or IMS AAA software on multiple computers or virtual machines (e.g., Solaris zones) requires multiple licenses, regardless of whether such computers or virtualizations are physically contained on a single chassis.
c. Product purchase documents, paper or electronic user documentation, and/or the particular licenses purchased by Customer may specify limits to Customers use of the Software. Such limits may restrict use to a maximum number of seats, registered endpoints, concurrent users, sessions, calls, connections, subscribers, clusters, nodes, realms, devices, links, ports or transactions, or require the purchase of separate licenses to use particular features, functionalities, services, applications, operations, or capabilities, or provide throughput, performance, configuration, bandwidth, interface, processing, temporal, or geographical limits. In addition, such limits may restrict the use of the Software to managing certain kinds of networks or require the Software to be used only in conjunction with other specific Software. Customers use of the Software shall be subject to all such limitations and purchase of all applicable licenses.
d. For any trial copy of the Software, Customers right to use the Software expires 30 days after download, installation or use of the Software. Customer may operate the Software after the 30-day trial period only if Customer pays for a license to do so. Customer may not extend or create an additional trial period by re-installing the Software after the 30-day trial period.
e. The Global Enterprise Edition of the Steel-Belted Radius software may be used by Customer only to manage access to Customers enterprise network. Specifically, service provider customers are expressly prohibited from using the Global Enterprise Edition of the Steel-Belted Radius software to support any commercial network access services.
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, sell, 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 or any product in which the Software is embedded; (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, service, application, operation, or capability without first purchasing the applicable license(s) and obtaining a valid key from Juniper, even if such feature, function, service, application, operation, 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 Embedded Software on non-Juniper equipment; (j) use Embedded Software (or make it available for use) on Juniper equipment that the Customer did not originally purchase from Juniper or an authorized Juniper reseller; (k) disclose the results of testing or benchmarking of the Software to any third party without the prior written consent of Juniper; or (l) 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.
iii
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 for Customers internal business purposes.
7. Ownership. Juniper and Junipers 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. The warranty applicable to the Software shall be as set forth in the warranty statement that accompanies the Software (the Warranty Statement). Nothing in this Agreement shall give rise to any obligation to support the Software. Support services may be purchased separately. Any such support shall be governed by a separate, written support services agreement. TO THE MAXIMUM EXTENT PERMITTED BY LAW, JUNIPER SHALL NOT BE LIABLE FOR ANY 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 IN THE WARRANTY STATEMENT 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. In no event shall Junipers or its suppliers or licensors liability to Customer, whether in contract, tort (including negligence), breach of warranty, or otherwise, exceed the price paid by Customer for the Software that gave rise to the claim, or if the Software is embedded in another Juniper product, the price paid by Customer for such other product. Customer acknowledges and agrees that Juniper has set its prices and entered into this Agreement in reliance upon the disclaimers of warranty and the limitations of liability set forth herein, that the same reflect an allocation of risk between the Parties (including the risk that a contract remedy may fail of its essential purpose and cause consequential loss), and that the same form an essential basis of the bargain between the Parties.
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 Customers possession or control.
10. Taxes. All license fees payable under this agreement are exclusive of tax. Customer shall be responsible for paying Taxes arising from the purchase of the license, or importation or use of the Software. If applicable, valid exemption documentation for each taxing jurisdiction shall be provided to Juniper prior to invoicing, and Customer shall promptly notify Juniper if their exemption is revoked or modified. All payments made by Customer shall be net of any applicable withholding tax. Customer will provide reasonable assistance to Juniper in connection with such withholding taxes by promptly: providing Juniper with valid tax receipts and other required documentation showing Customers payment of any withholding taxes; completing appropriate applications that would reduce the amount of withholding tax to be paid; and notifying and assisting Juniper in any audit or tax proceeding related to transactions hereunder. Customer shall comply with all applicable tax laws and regulations, and Customer will promptly pay or reimburse Juniper for all costs and damages related to any liability incurred by Juniper as a result of Customers non-compliance or delay with its responsibilities herein. Customers obligations under this Section shall survive termination or expiration of this Agreement.
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 Customer may contain encryption or other capabilities restricting Customers 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. Interface Information. To the extent required by applicable law, and at Customer's written request, Juniper shall provide Customer with the interface information needed to achieve interoperability between the Software and another independently created program, on payment of applicable fee, if any. Customer shall observe strict obligations of confidentiality with respect to such information and shall use such information in compliance with any applicable terms and conditions upon which Juniper makes such information available.
14. Third Party Software. Any licensor of Juniper whose software is embedded in the Software and any supplier of Juniper whose products or technology are embedded in (or services are accessed by) the Software shall be a third party beneficiary with respect to this Agreement, and such licensor or vendor shall have the right to enforce this Agreement in its own name as if it were Juniper. In addition, certain third party software may be provided with the Software and is subject to the accompanying license(s), if any, of its respective owner(s). To the extent portions of the Software are distributed under and subject to open source licenses obligating Juniper to make the source code for such portions publicly available (such as the GNU General Public License (GPL) or the GNU Library General Public License (LGPL)), Juniper will make such source code portions (including Juniper modifications, as appropriate) available upon request for a period of up to three years from the date of distribution. Such request can be made in writing to Juniper Networks, Inc., 1194
N. Mathilda Ave., Sunnyvale, CA 94089, ATTN: General Counsel. You may obtain a copy of the GPL at http://www.gnu.org/licenses/gpl.html, and a copy of the LGPL at http://www.gnu.org/licenses/lgpl.html.
15. Miscellaneous. This Agreement shall be governed by the laws of the State of California without reference to its conflicts of laws principles. The provisions of the U.N. Convention for the International Sale of Goods shall not apply to this Agreement. 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
iv
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. This Agreement and associated documentation has been written in the English language, and the Parties agree that the English version will govern. (For Canada: Les parties aux présentés confirment leur volonté que cette convention de même que tous les documents y compris tout avis qui s'y rattaché, soient redigés en langue anglaise. (Translation: The parties confirm that this Agreement and all related documentation is and will be in the English language)).

System Logging Overview
E Series Broadband Services Routers enable you to log system events to discover and isolate problems with your system. This chapter explains how to use the command-line interface (CLI) to monitor your systems log configuration and stay informed about all system events that you want to track.
This chapter contains the following sections:
Overview of System Logging on page 3
Logging Platform Considerations on page 5
Configuring Event Logging on page 5
Configuring Log Severity for Individual and Systemwide Logs on page 10
Configuring Log Verbosity for Individual Logs or All Logs on page 14
Setting the Timestamp for Log Messages on page 14
Configuring Log Filters on page 16
Turning Off Log Filters on page 17
Monitoring Logging System Events on page 17
Overview of System Logging
System events are classified into event categories. Using the CLI, you can determine which event categories to log. To fully utilize the logging facility, you need to understand log severity and log verbosity.
Log Severity
Log severity is a level that is assigned to an event or log message. Log severity levels apply to event categories, such as bulkStats, bgpRoutes, or atm1483.
The minimum severity of a log message for an individual category is described either by a severity number in the range 0–7 or a descriptive priority term, such as emergency or debug. The lower the severity number is, the higher the priority. See Table 3 on page 4.
Overview of System Logging 3
JUNOSe 11.1.x System Event Logging Reference Guide
NOTE: Not every event category supports every severity level. For a list of event categories and the severity levels that each category supports, see Event Categories on page 23.
Table 3: Log Severity Descriptions
System ResponseSeverity NameSeverity Number
System unusable; shelf resetEmergency0
Immediate action needed; card resetAlert1
Critical conditions exist; interface is downCritical2
Error conditions; nonrecoverable software errorError3
Warning conditions; recoverable software errorWarning4
Log Verbosity
Notice5
Info6
Normal but significant conditions; nonerror, low-verbosity information
Informational messages; nonerror, medium-verbosity information
Debug messages; nonerror, high-verbosity informationDebug7
The verbosity level determines the amount of information that appears in each message. You can assign the verbosity level for the log category. Verbosity levels can be any of the following:
LowTerse
MediumModerate
HighVerbose
NOTE: Many event categories provide only low-verbosity detail regardless of the verbosity setting.
Persistent Logs
Log messages can survive a system reboot. After a reboot, the system rebuilds the list of log messages. However, if the system detects any problems or has gone through a power cycle, the buffer is reset, and the log messages from the previous session are lost.
4 Overview of System Logging
Log messages are not synchronized between primary and redundant SRP modules. During a switchover from a primary to a redundant SRP module, existing log messages are not transferred to the redundant SRP module.
Logging Platform Considerations
System logs are supported on all E Series routers.
For information about the modules supported on E Series routers:
See the ERX Module Guide for modules supported on ERX7xx models, ERX14xx
models, and the Juniper Networks ERX310 Broadband Services Router.
See the E120 and E320 Module Guide for modules supported on the Juniper
Networks E120 and E320 Broadband Services Routers.
Configuring Event Logging
Chapter 1: System Logging Overview
By default, event logging is enabled and has default settings. This section explains how to change settings to customize event logging to fit your needs.
Set a baseline for when the system begins logging messages.
host1#baseline log 11:12:55 April 30 2002
Set the log severity.
host1(config)#log severity warning
Remove the limit on the number of buffers available for an event category.
host1(config)#log unlimit qos
Set the log verbosity.
host1(config)#log verbosity low
Log messages to a specified destination.
host1(config)#log destination syslog 10.10.9.5 include ospfGeneral
mplsGeneral os
Select fields to be added to logs.
host1(config)#log fields timestamp instance no-calling-task
Enable logs destined for a console to be displayed at the current console device.
The next sections explain how to configure individual and systemwide logs, how to format timestamps for log messages, and how to configure log filters.
host1#log here
Logging Platform Considerations 5
JUNOSe 11.1.x System Event Logging Reference Guide
baseline log Use to set a baseline for logging events. Only log messages timestamped after
the baseline appear when you enter the show log data delta command.
To use the current system time, do not enter any options.
To set a specific time, use the following syntax:
Hour:Minute[:Second]Current time in 24-hour format. Seconds are optional.
utc—Enter this keyword to indicate that the time entered is in universal
coordinated time (UTC), rather than local time.
To set a specific date, use the following syntax:
Month Day YearYou must spell out the name of the month.
last-reset—Causes the system to display log messages generated since the last
time the system was reset
Examples
host1#baseline log 11:12:55 April 30 2002 host1#baseline log last-reset
There is no no version.
See baseline log.
log destination Use to log messages to the specified destination, including system log, console,
and nv-file (nonvolatile storage).
NOTE: You can display traffic logssuch as ipTraffic, icmpTraffic, tcpTraffic, and udpTrafficonly through the show log data command or from the SRP module console. You cannot redirect traffic logs elsewhere, such as to a system log or nonvolatile storage file, or to a Telnet session.
Use the severity keyword to limit the messages logged based on priority level.
The following information applies to logging messages to system log servers.
You can have multiple system log servers, but must configure logging to
each one separately.
A particular message within a specified event category is logged to a particular
system log server only if the priority of the message is greater than or equal to both the priority of the event category and the priority of that system log server.
If you log messages to a system log server, you can also specify:
6 Configuring Event Logging
facility—Specifies a facility ID on the system log destination host. The
range is 0–7, representing the logging facilities local0–local7.
include—Logs only the listed categories to system log; no other
categories are logged unless specifically included by issuing this command again.
