Dynamic Ranging Support

The functionality of the clear cable modem <mac-address> reset command is extended to send a
"Ranging Abort" message instead of just removing the SID.
A new modem state—Reset (display: resetting)— has been introduced into the modem state list. A
modem is deprovisioned when moving into this state as if going offline. Move the modem to the
Continue Ranging list. If a ranging request is received from the modem, send a "Ranging Abort"
message. Continue until an "Initial Ranging" message is received or until normal timeout (16 attempts).
If the modem does not go back to initial ranging, set it to offline.
The Reset modem state may show as follows in the output of the show cable modem command:
Cable4/0/U1 80 resetting 3575 0.25 3 0 10.30.160.26 0050.7318.e965
This is an intermediate state. A modem will not be in this state for more than a few seconds. If the modem
does not respond, it may remain in this state for up to 30 seconds. The subsequent modem state is offline.
For additional command information about the show cable modem command, refer to the
CMTS Cable Command Reference

Enhanced Modem Status Display

The Cisco uBR7200 series universal broadband router supports polling of the CMs to obtain parameter and
status information on an ongoing basis. Two new Cisco IOS commands are added to support this feature.
