Event 6—Establish the Time of Day
The Cisco uBR900 series accesses the ToD server for the current date and time, which is used to create
time stamps for logged events. The
CMAC_LOG_TOD_COMPLETE field indicates a successful time of day
sequence.

Event 7—Establish Security
This event is currently bypassed by the Cisco uBR900 series because “full security” has not been fully
defined by DOCSIS and is therefore not yet supported.

508177.162 CMAC_LOG_SECURITY_BYPASSED
Note “Full security” was a request made by cable service providers for a very strong
authorization and authentication check by the CMTS. The Cisco uBR900 series supports
DOCSIS Baseline Privacy (Event 10), which protects your data from being “sniffed” on the
cable network.
Event 8—Transfer Operational Parameters
After completing the DHCP and security operations, the Cisco uBR900 series downloads operational
parameters by downloading a configuration file located on the TFTP server. The
CMAC_LOG_DHCP_CONFIG_FILE_NAME field shows the filename containing the transmission parameters.

Event 9—Perform Registration
After the Cisco uBR900 series is initialized, authenticated, and configured, it requests to be registered
with the headend CMTS. The
CMAC_LOG_COS_ASSIGNED_SID field assigns a CoS number and a SID.
Multiple CoS entries in the configuration file imply that multiple SIDs are supported by the cable access
router. If several cable access routers use the same configuration file, they will have the same CoS
numbers but will be assigned different SIDs.
A successful registration is indicated by the
CMAC_LOG_REGISTRATION_OK field.
