Verifying Cable Modem Clearing and Resetting

Maintenance List and forced it to start a reset sequence, enter the show cable modem command:

Troubleshooting Tips
To troubleshoot the configuration, perform the following tasks:
• Make sure you entered the correct cable modem IP address or MAC address when you typed the
command.
• This command is useful if an SNMP manager is not available, or if the cable modem is unable to
obtain an IP address or respond to SNMP messages.
Note It might take up to 30 seconds for the cable modem to start the reset sequence.
