Cisco AR Directory Structure

concurrently, you might create two Session Managers and three Resource Managers. One dynamic IP Resource Manager that is referenced by both Session Managers, and two concurrent session Resource Managers, one for each Session Manager.

In addition, Cisco Access Registrar lets you pose queries about sessions. For example, you can query Cisco Access Registrar about which session (and thus which NAS-Identifier, NAS-Port and/or User-Name) owns a particular resource, as well as query Cisco Access Registrar about how many resources are allocated or how many sessions are active.

Cisco AR Directory Structure

The installation process populates the /opt/CSCOar directory with the subdirectories listed in Table 2-1.

Note This directory structure is different from that of previous version of Cisco AR.
