Managing Resources

This chapter provides information and procedures for managing Cisco ISE network resources and contains the following topics:

Dictionaries and Dictionary Attributes

Dictionaries are domain-specific catalogs of attributes and allowed values that can be used to define access policies for a domain. An individual dictionary is a homogeneous collection of attribute type. Attributes that are defined in a dictionary have the same attribute type and the type indicates the source or context of a given attribute.

Attribute types can be one of the following:

  • MSG_ATTR
  • ENTITY_ATTR
  • PIP_ATTR

In addition to attributes and allowed values, a dictionary contains information about the attributes such as the name and description, data type, and the default values. An attribute can have one of the following data types: BOOLEAN, FLOAT, INTEGER, IPv4, OCTET_STRING, STRING, UNIT32, and UNIT64.

Cisco ISE creates system dictionaries during installation and allows you to create user dictionaries.

System Defined Dictionaries and Dictionary Attributes

Cisco ISE creates system dictionaries during installation that you can find in the System Dictionaries page. System-defined dictionary attributes are read-only attributes. Because of their nature, you can only view existing system-defined dictionaries. You cannot create, edit, or delete system-defined values or any attributes in a system dictionary.

A system-defined dictionary attribute is displayed with the descriptive name of the attribute, an internal name as understood by the domain, and allowed values.

Cisco ISE also creates dictionary defaults for the IETF RADIUS set of attributes that are also a part of the system-defined dictionaries, which are defined by the Internet Engineering Task Force (IETF). You can edit all free IETF RADIUS attribute fields except the ID.

Displaying System Dictionaries and Dictionary Attributes

You cannot create, edit, or delete any system-defined attribute in a system dictionary. You can only view system-defined attributes. You can perform a quick search that is based on a dictionary name and description or an advanced search that is based on a search rule that you define.


Step 1 Choose Policy > Policy Elements > Dictionaries > System .

Step 2 Choose a system dictionary in the System Dictionaries page, and click View .

Step 3 Click Dictionary Attributes .

Step 4 Choose a system dictionary attribute from the list, and click View .

Step 5 Click the Dictionaries link to return to the System Dictionaries page.


 

User-Defined Dictionaries and Dictionary Attributes

Cisco ISE displays the user-defined dictionaries that you create in the User Dictionaries page. You cannot modify the values for Dictionary Name or Dictionary Type for an existing user dictionary once created and saved in the system.

You can do the following in the User Dictionaries page:

  • Edit and delete user dictionaries.
  • Search user dictionaries based on name and description.
  • Add, edit, and delete user-defined dictionary attributes in the user dictionaries.
  • Add or remove allowed values for dictionary attributes.

RADIUS-Vendor Dictionaries

Cisco ISE allows you to define a set of RADIUS-vendor dictionaries, and define a set of attributes for each one. Each vendor definition in the list contains the vendor name, the vendor ID, and a brief description.

Cisco ISE provides you the following RADIUS-vendor dictionaries by default:

  • Airespace
  • Cisco
  • Cisco-BBSM
  • Cisco-VPN3000
  • Microsoft

The RADIUS protocol supports these vendor dictionaries, and the vendor-specific attributes that can be used in authorization profiles and in policy conditions.
