Figure 14-4 Redirecting CPE to Home Provisioning Group
1.
The CPE attempts to establish a session with DPE 1 in provisioning group 1 (PG 1).
2. DPE 1 in PG 1 searches its cache for the device.
If it cannot find an entry for that device, the DPE sends a request to the best available DPE in each
provisioning group to find out whether the device belongs to that group.
Only one DPE per provisioning group is queried.
3. The DPEs that receive the request in each provisioning group, send their reply to DPE 1.
If a provisioning group responds that the device belongs to its group, then DPE 1 in PG 1 redirects
the CPE to its home provisioning group.
4. The CPE attempts to establish a session with its home provisioning group.
To enable the home provisioning group redirection feature, you must configure the home provisioning
group redirection service on the DPE. See Configuring Home Provisioning Group Redirection Service
on the DPE, page 3-9.
Correcting a Device’s Provisioning Group
You can also just reset an incorrect provisioning group specification on the device. In this scenario, you
do not need to change the actual device—you only need to update Cisco BAC.
To change an incorrect provisioning group from the API, invoke the
IPDevice.changeProperties()
API and include the IPDeviceKeys.HOME_PROV_GROUP property with the corrected provisioning group.
For details, refer to the API Javadoc which is available at BPR_HOME/docs/nb-api/javadoc.
To change an incorrect provisioning group specification from the administrator user interface:
Note If you change the home provisioning group from the administrator user interface, you only correct the
provisioning group in Cisco BAC; the change does not affect the device.
