This page displays the output of the show tech-support command, which includes the output of the
following CLI commands:
• show version—Displays the hardware configuration, software image names and version, register
settings, and the boot image.
• show running-config—Displays the configuration the router is currently using.
• show stacks—Displays the stack usage of the router’s processes and interrupt routines, including
the reason for the last system reboot.
• show interfaces—Displays the status and configuration of the router’s Ethernet and cable
interfaces.
• show controllers—Displays the current state, configuration, and register information for each
controller that the Cisco uBR924 router uses to move data between the cable and Ethernet interfaces.
• show controller c0 mac state—Displays the MAC layer configuration for the cable interface.
• show voice port—Displays the configuration of each voice port.
• show dial-peer voice—Displays the remote and local dial-peers that have been configured on the
router.
• show gateway—Displays the gateway configuration (if any).
• show call active voice—Displays the contents of the active call table, which shows statistics for the

through the router’s voice ports.

If an enable password has been set, the user must enter the level 15 user ID and password to access this
page. If no enable password has been set, this page is accessible to all users.
Note Cisco recommends that an encrypted enable password be set on all Cisco uBR924 routers that are
deployed at subscriber sites. If an encrypted enable password is not being used at a subscriber’s site, the
Cable Monitor should not be enabled in advanced mode because the Debug Information page displays
information, such as the SNMP community strings, that could be used to defeat the router’s security.
Figure B-7 shows a typical Debug Information page.
