Command History
Usage Guidelines
The DOCSIS 1.1 specification states that the CMTS should enforce the T9 timer, which is a registration
timeout timer that specifies the maximum time allowed between the CMTS sending a successful Ranging
Response (RNG-RSP) message and the CM replying with a Registration Request (REG-REQ) message.
If this timer expires, the CMTS must remove the CM from its list of active CMs, and the CM must restart
the registration process.
The
cable registration-timeout
command can be used to customize the value of the T9 timer for each
cable interface, to accommodate the CMs using that interface.
Examples
The following example shows the registration timeout value being increased from 3 minutes to
10 minutes:
router#
configure terminal
router#(config)#
interface c6/0
router(config-if)#
cable registration-timeout 10
router(config-if)#
exit
router(config)#
minutes
Sets the value of the DOCSIS CM registration timeout timer
(T9 timer). Valid range is from 2 to 60 minutes. The default is 3
minutes.
