DEFINING APPLICATION MAPPINGS

By default, STRM can classify many applications. When creating new or
customized application mappings, you must:

Step 1 Update the Application Views in the STRM Administration interface, which

contains group and object information. For more information on updating the
Applications Views, see the STRM Administration Guide.

Step 2 Configure the application mapping parameters in the Flow Collector parameters.

For more information, see the STRM Administration Guide.

Step 3 Update the mapping file, which contains user defined application mappings. This

file maps user defined applications with STRM’s Application Views.

Step 4 Deploy the changes to other systems through the Administration Console. For

more information, see the STRM Administration Guide.
This chapter provides information on configuring and editing applications in STRM

including:

About the STRM
Applications View

• About the STRM Applications View

• Defining Application Mappings

Once a flow is detected, STRM assigns an application ID to the flow based on the
content of the flow, the protocol used for the flow, and the port. The particular
application ID assigned to a flow depends on the values configured in the mapping
files. This file also allows the application ID to be mapped to values defined in the
Application View of your STRM interface, which also allows the classified data to
be stored and displayed on the STRM graphs, based on the defined application ID.

Figure 1-1 shows an example of the Chat Application View in the STRM interface,

which shows the associated ID in the Values column.

STRM Default Application Configuration Guide

2 DEFINING APPLICATION MAPPINGS

Figure 1-1 Example of Application View

Y o u can edit the user defined mapping file to ensure specific traffic is appropriately
classified in the STRM interf ace. Ho wever, STRM also includes default application
IDs, which you can view in the Applications View of the STRM interface. For
example, in Figure 1-1, the Chat group includes the default AOL group, which is
defined in the default mapping file to ensure all AOL traffic is assigned a value of

3001. For more information on the default values, see Chapter 2 Default

Applications.

Note: For more information on enabling or disabling application detection, see the
STRM Administration Guide.

Defining
Application
Mappings

To define application mappings:

Step 1 Using SSH, log in to STRM.
Step 2 Open the following file:

/store/configservices/staging/globalconfig/user_application_
mapping.conf

Note: To edit the name of the user_application_mapping.conf file, you can edit the
User Application Mapping parameter in the Flow Processor configuration window.
For more information, see the STRM Administration Guide. If the
user_application_mapping.conf does not exist in your system, create the file and
place the empty in the above directory.

Step 3 Update the file, as necessary.

When updating the file, note the following:

• Each line in the file indicates a new mapped application. You can specify

multiple mappings (each on a seperate line) for the same application.

• You can specify a wildcard character * for any of the fields. The wildcard

character must be used alone and not part of a comma separated list. The
wildcard character indicates that this field applies to all flows.

STRM Default Application Configuration Guide

Defining Application Mappings 3

• Since it is possible for a flow to be associated with multiple mappings, a flow is

mapped to an application ID based on the order of the file. The first mapping
that applies in the file is assigned to the flow.

• When adding new application identification numbers, we recommend that you

apply numbers ranging between 15,000 to 20,000 . Contact Juniper Networks
Customer Support for further information.

The format of the entry must resemble the following:

<New ID> <Old ID> <Source IP Address>:<Source Port> <Dest IP
Address>:<Dest Port> <Name>

Where:

• <New ID> specifies the application ID you wish to assign to the flow. A value of

1 indicates an unknown application. If the ID you wish to assign does not exist,
you must create the ID using the Application View in the STRM interface. For
more information, see the STRM Administration Guide.

• <Old ID> specifies the default application ID of the flow, as assigned by

STRM. A value of * indicates a wildcard. For more information on the default
values, see Chapter 2 Default Applications.

• <Source IP Address> specifies the source IP address of the flow. This field

may contain either a comma separated list of addresses or CIDR values. A
value of * indicates a wildcard, which means that this field applies to all flows.

• <Source Port> specifies the associated port. This field may contain a comma

separated list of values or ranges specifies in the format: <lower port
number>-<upper port number>. A value of * indicates a wildcard, which means
that this field applies to all flows.

• <Dest IP Address> specifies the destination IP address of the flow. This field

may contain either a comma separated list of addresses or CIDR values. A
value of * indicates a wildcard, which means that this field applies to all flows.

• <Dest Port> specifies the associated destination source port. This field may

contain a comma separated list of values or ranges specifies in the format:
<lower port number>-<upper port number>. A value of * indicates a wildcard,
which means that this field applies to all flows.

• <Name> specifies a name you wish to assign to this mapping. This field is

optional.

For example, the below example maps all flows that match the IP addresses and
ports for which the Flow Collector has assigned to the Old ID of 1010 and assign
the new ID of 15000:

15000 1010 10.100.100/24,10.100.50.10:* 172.14.33.33:80,443

Step 4 Save and exit the file.
Step 5 Log-in to STRM.
Step 6 Click Config to access the Administration Console.
Step 7 If necessary, edit your Application View.

DEFAULT APPLICATIONS

STRM includes default application IDs, which you can view in the Applications
View of the STRM interface. This chapter provides the default application values
as they appear in the Applications View. The default application values apply to all
source and destination flows, however, the destination port is specific to the
application.

For more information on the Application View, see the STRM Administration

Guide.
