Chapter 2 Cisco CMTS Configuration Commands
cable submgmt default
cable submgmt default
To set the default values for attributes in the Subscriber Management MIB (DOCS-SUBMGT-MIB), and
to enable Cisco Static CPE Override on the Cisco CMTS, use the
cable submgmt default
global
configuration command. To restore the original defaults, use the
no
form of this command.

Syntax Description
no
When used with the
active
and
learnable
options, the
no
form of the
command sets the default attributes to false. When used with the
max-cpe
and
filter-group
options, the
no
form of the command sets the attribute to 0.
active
Sets the docsSubMgtCpeActiveDefault attribute, which controls whether
the CMTS manages the CPE devices for a particular CM—when set to
TRUE, the CMTS enforces the MAX-CPE value and the implemented
filters. The
no cable submgmt default active
command sets the default
value to FALSE (the original default), which turns off CPE management at
the CMTS.
learnable
Sets the docsSubMgtCpeLearnableDefault attribute, which controls
whether the CMTS learns the CPE IP addresses for a particular CM—when
set to TRUE (the original default), the CMTS learns IP addresses up to the
MAX-CPE value. The
no cable submgmt default learnable
command sets
the default value to FALSE, which means that the IP address for each
allowable CPE device must be specified in the DOCSIS configuration file.
max-cpe
cpe-num
Sets the docsSubMgtCpeMaxIpDefault attribute, which specifies the
default number of simultaneous IP addresses (CPE devices) permitted for
the CM. The possible range is 0 to 1024, where 0 specifies that all CPE
traffic from the CM is dropped. The default is 16.
filter-group
Specifies a filter group, which can be applied to either upstream or
downstream traffic for either a CM or its CPE devices.
cm
Specifies that the filter group applies to traffic to or from a CM.
cpe
Specifies that the filter group applies to traffic to or from a CPE device.
downstream
Specifies that the filter group applies to the downstream traffic that is going
to the specified CM or CPE device.
upstream
Specifies that the filter group applies to the upstream traffic that is coming
from the specified CM or CPE device.
group-id
Specifies the filter group ID (0 to 1024) to be applied for the CM or CPE,
downstream or upstream filter. This ID references the filter indexes that are
used for rows in the docsSubMgtPktFilterTable. A value of 0 indicates that
no filtering is used for this particular type of traffic.
