Resource Manager Protocol
Resource Manager Protocol (RMP) is a robust, recoverable protocol used for communication between
the Cisco RPMS and the NAS. Each NAS client uses RMP to communicate resource management
requests to the Cisco RPMS server. RPMS also periodically polls the NAS clients to query their current
call information or address error conditions when they occur. RMP also allows for protocol attributes
that make it extensible and enable support for customer billing requirements.
Figure 108 shows the relationship of Cisco RPM CLID/DNIS Call Discriminator Feature and RMP.

Note RMP must be enabled on all NASes that communicate with the Cisco RPM CLID/DNIS Call
Discriminator Feature.
