Configuring Subscriber-End Broadband Access Router Features
Subscriber-End Broadband Access Router Initial Power-Up Sequence
MC-630
Cisco IOS Multiservice Applications Configuration Guide
Downloading a DOCSIS configuration file to a Cisco uBR900 series cable access router automatically
causes the following actions:
• Ends all Telnet sessions
• Disables the cable access router console port, preventing local access to the CLI
• Performs a write-erase on the cable access router local configuration parameters
Telnet access to the router from the headend is still allowed, but only if the Cisco IOS configuration file
includes enable and line vty passwords; if the configuration file does not include enable and line vty
commands to specify these passwords, Telnet access and console access are both disabled.
The sequence numbers shown in Table 40 are also shown in Figure 114. The Cisco uBR900 series cable
access router will complete all the steps shown in the table and flowchart each time it needs to reregister
with the CMTS.
