BRCM-CM-MGMT-MIB Table View

A table describing the characteristics of each downstream channel.  An
entry exists in this table for each entry in the ifTable with an 
ifType value of docsCableDownstream (128).

cmDownstreamChannelInfoEntry row .1.3.6.1.4.1.4413.2.2.2.1.2.1.8.1

An entry describing the attributes of a single downstream channel.

The table of IP filters to be applied to traffic originating from
or destined to this device.  The fields in this table are loosely 
based on a subset of the fields in the docsDevFilterIpTable as defined 
in the DOCS-CABLE-DEVICE-MIB.  The key difference is that the filters 
described by the cmHostIpFilterTable are not applied to bridged  
traffic, but rather to traffic which is sent from or received by the 
cablemodem itself, acting in a role as a host.
          
This table may be used to restrict certain IP traffic (eg SNMP, 
TFTP, telnet, etc.) from being accessible via the CPE and / or HFC
interfaces.  Note that all filters will be applied to all IP
addresses associated with this host.
          
Caution must be exercised in the use of this table.  For example, it 
is possible to render the device unmanageable if SNMP is prohibited 
over both CPE and CM interfaces.

cmHostIpFilterEntry row .1.3.6.1.4.1.4413.2.2.2.1.2.2.1.1

An instance of an IP filter. Entries in the cmHostIpFilterTable are
created and deleted using the cmHostIpFilterStatus object.

Each filter describes a set of criteria against which each IP packet
will be …
