Cisco Cisco Broadband Access Center for Cable 2.7 Release Notes

Although this feature was supported in previous BACC releases, specifically 
through the use of custom RDU extensions, BACC 2.7 now supports lease 
reservation operations through the use of the BACC API and administrator’s user 
interface.

This feature is only supported when Network Registrar, version 6.1.2.3 or later, is 
in use with the Regional CCM feature that is deployed.
The Lease Reservation feature in BACC 2.7 works only in scenarios involving a 
single Network Registrar DHCP server with no failover configured. This feature 
is not supported in cases involving failover DHCP servers. Cisco will add more 
functional use of this feature in a later version of BACC.

Unlike previous BACC releases, where only one DOCSIS shared secret (DSS) 
was supported, BACC 2.7 now supports the use of DSS on a per-DPE basis. 
Changing the DSS no longer requires the regeneration of devices using that DSS; 
the new value is available immediately.

You can use this feature to define multiple different DOCSIS shared secrets for 
devices belonging to different CMTSs. In this way, if the shared secret is 
compromised, only a limited number of CMTSs are compromised.

You can use this feature to troubleshoot a specific device (or a small set of 
devices) throughout the RDU, DPE, and Network Registrar extensions. 

For information on BACC bugs, see the BACC27_BugList.html file in the /docs 
subdirectory of the BACC CD-ROM or electronic distribution.
