Edit Configuration (J-Web Configuration Editor)
To access Edit Configuration, also called the J-Web configuration
editor, select Configuration>View and Edit>Edit Configuration. This page allows you to configure all routing platform services
that you can configure from the JUNOS CLI. Each field in the J-Web
configuration editor has the same name as the corresponding configuration
statement at the same hierarchy level in the CLI. For example, the
Policy Options field corresponds to the policy-options statement
in the CLI. As a result, you can easily switch from one interface
to the other or follow a CLI configuration example using the J-Web
configuration editor.
Table 30 lists key
J-Web configuration editor tasks and their functions.
Table 30: J-Web Configuration Editor Tasks Summary
| J-Web Configuration
Editor Task |
Function
|
|
Access
|
Configure network access. For example, you can configure the
Point-to-Point Protocol (PPP), the tracing access processes, the Layer
2 Tunneling Protocol (L2TP), RADIUS authentication for L2TP, and Internet
Key Exchange (IKE) access profiles. For more information, see the JUNOS System Basics Configuration Guide.
|
|
Accounting options
|
Configure accounting profiles. An accounting profile represents
common characteristics of collected accounting data, including collection
interval, accounting data files, and counter names on which to collect
statistics. On the Accounting options pages, you can configure multiple
accounting profiles, such as the interface, filter, MIB, routing engine
and class usage profiles. For more information, see the JUNOS Network Management Configuration Guide.
|
|
Applications
|
Define applications by protocol characteristics and group the
applications you have defined into a set. On the Applications pages,
you can configure application properties such as, Internet Control
Message Protocol (ICMP) code and type. You can also specify application
protocols—also known as application level gateways (ALGs)—to
be included in an application set for service processing, or specify
network protocols to match in an application definition. For more
information, see the JUNOS Services Interfaces Configuration Guide.
|
|
Chassis
|
Configure routing platform chassis properties. On the Chassis
pages, you can configure different properties of the routing platform
chassis, including conditions that activate the red and yellow alarm
LEDs on the routing platforms and SONET/SDH framing and concatenation
properties for individual Physical Interface Cards (PICs). For more
information, see the JUNOS System Basics Configuration Guide.
|
|
Class of service
|
Define class-of-service (CoS) components, such as CoS value
aliases, classifiers, forwarding classes, rewrite rules, schedulers,
and virtual channel groups. The Class of service pages also allow
you to assign CoS components to interfaces. For more information,
see the JUNOS Class of Service Configuration Guide.
|
|
Event options
|
Configure event policies. An event policy is an if-then-else
construct that defines actions to be executed by the software on receipt
of a system log message. For each policy, you can configure multiple
actions, as follows—ignore the event, upload a file to a specified
destination, execute JUNOS software operational mode commands, or
execute JUNOS event scripts (op scripts). For more information, see
the JUNOS Configuration and Diagnostic Automation Guide.
|
|
Firewall
|
Configure stateless firewall filters. With stateless firewall
filters—also known as ACLs—you can control packets transiting
the routing platform to a network destination and packets destined
for and sent by the routing platform. On the Firewall pages, you can
create filters and add terms to them. For each term, you can set the
match conditions and associate actions to be performed on packets
matching these conditions. For more information, see the JUNOS Policy Framework Configuration Guide.
|
|
Forwarding options
|
Configure traffic forwarding and traffic sampling options. You
can sample IP traffic based on particular input interfaces and various
fields in the packet header. You can also use traffic sampling to
monitor any combination of specific logical interfaces, specific protocols
on one or more interfaces, a range of addresses on a logical interface,
or individual IP addresses.
Traffic forwarding policies allow you to control the per-flow
load balancing, port mirroring, and Domain Name System (DNS) or Trivial
File Transfer Protocol (TFTP) forwarding. For more information, see
the JUNOS Policy Framework Configuration Guide.
|
|
Interfaces
|
Configure physical and logical interface properties. For the
physical interface on the routing platform, you can modify default
values for general interface properties, such as the interface’s
maximum transmission unit (MTU) size, link operational mode, and clock
source. For each logical interface, you can specify the protocol family
and other logical interface properties. For more information, see
the JUNOS Network Interfaces Configuration Guide.
|
|
Policy options
|
Configure policies by specifying match conditions and associating
actions with the conditions. On the Policy options page you can create
a named community and define autonomous system (AS) paths, damping
parameters, and routing policies. You can also create a named prefix
list and include it in a routing policy. For more information, see
the JUNOS VPNs Configuration Guide.
|
|
Protocols
|
Configure routing protocols such as Border Gateway Protocol
(BGP), Distance Vector Multicast Routing Protocol (DVMRP), Intermediate
System-to-Intermediate System (IS-IS), Multiprotocol Label Switching
(MPLS), Open Shortest Path First (OSPF), Resource Reservation Protocol
(RSVP) and Routing Information Protocol (RIP). For more information,
see the JUNOS Routing Protocols Configuration Guide and the JUNOS MPLS Applications Configuration Guide.
|
|
Routing instances
|
Configure routing instances. A routing instance is a collection
of routing tables, interfaces, and routing protocol parameters. On
the Routing instances pages, you can configure the following types
of routing instances: forwarding, Layer 2 virtual private network
(VPN), nonforwarding, VPN routing and forwarding (VRF), virtual rourter,
and virtual private LAN service (VPLS). For more information, see
the JUNOS Routing Protocols Configuration Guide.
|
|
Routing options
|
Configure protocol-independent routing options that affect system-wide
routing operations. On the Routing options pages, you can perform
the following tasks:
- Add routing table entries, including static routes, aggregated
(coalesced) routes, generated routes (routes of last resort), and
martian routes (routes to ignore).
- Create additional routing tables and routing table groups.
- Set the AS number of the routing platform for use by BGP.
- Set the router ID, which is used by BGP and OSPF to identify
the routing platform from which a packet originated.
- Define BGP confederation members for use by BGP.
- Configure how much system logging information to log for
the routing protocol process.
- Configure system-wide tracing (debugging) to track standard
and unusual routing operations and record this information in a log
file.
For more information, see the JUNOS Routing Protocols Configuration Guide
|
|
Security
|
Configure Internet Protocol Security (IPSec) for authentication
of origin, data integrity, confidentiality, replay protection, and
nonrepudiation of source. In addition to IPSec, you can configure
the Internet Key Exchange (IKE), which defines mechanisms for key
generation and exchange, and manages security associations (SAs).
You can also configure the SSH known host list, and the trace options
for IPSec key management. For more information, see the JUNOS System Basics Configuration Guide.
|
|
Services
|
Configure application settings for services interfaces, such
as dynamic flow capture parameters, the Intrusion Detection System
(IDS), IPSec VPN service, RPM, stateful firewalls, and Network Address
Translation (NAT). For more information, see the JUNOS Services Interfaces Configuration Guide.
|
|
Snmp
|
Configure SNMP to monitor network devices from a central location.
You can specify an administrative contact and location and add a description
for each system being managed by SNMP. You can also configure SNMP
community strings, trap options, and interfaces on which SNMP requests
can be accepted. For more information, see the JUNOS Network Management Configuration Guide.
|
|
System
|
Configure system management functions, including the router’s
hostname, address, and domain name; the addresses of Domain Name System
(DNS) servers; user login accounts, including user authentication
and the root-level user account; time zones and Network Time Protocol
(NTP) properties; and properties of the router’s auxiliary and
console ports. For more information, see the JUNOS System Basics Configuration Guide.

at the displayed hierarchy level and below. All subordinate statements
and identifiers contained within a deleted statement are also deleted.
- To confirm the discard operation or deletion,
click OK.
To cancel a discard operation or deletion, click Cancel.
The updated candidate configuration does not take effect on
the routing platform until you commit it.
Committing
a Configuration
When you finish making changes to a candidate configuration
with the J-Web configuration editor, you must commit the changes
to use them in the current operational software running on the routing platform.
If another user is editing an exclusive candidate configuration
with the CLI, you cannot commit a configuration until the user has
committed the configuration. To display a list of users, see Displaying Users Editing the Configuration. For more information about
editing an exclusive candidate configuration, see the JUNOS CLI User Guide.
To commit a candidate configuration:
- In the J-Web configuration editor,
click Commit.
The main pane displays a summary of your changes in statement
form.
- To confirm the commit operation, click OK.
To cancel a commit operation, click Cancel.
If multiple users are editing the configuration when you commit
the candidate configuration, all changes made by all users take effect.
- To display all the edits applied to the running
configuration, click Refresh.
Sample Task—Configuring Accounting
Options
Figure 19 shows the Accounting
options configuration page. This page displays the different settings
that you can configure at the accounting options hierarchy level.
Because each field in the J-Web configuration editor has the same
name as the corresponding configuration statement at the same hierarchy
level in the CLI, the options on this page match the options displayed
when you enter edit accounting options in the CLI:
user@router# edit accounting-options
?
Possible completions:
<[Enter]> Execute this command
> class-usage-profile Class usage profile for accounting data
> file Accounting data file configuration
> filter-profile Filter profile for accounting data
> interface-profile Interface profile for accounting data
> mib-profile MIB profile for accounting data
> routing-engine-profile Routing Engine profile for accounting data
