| cabhCapMib | 1.3.6.1.4.1.4491.2.4.3 | | | This MIB module supplies the basic management objects
for the CableHome Addressing Portal (CAP) portion of
the PS. |
| cabhCapObjects | 1.3.6.1.4.1.4491.2.4.3.1 | | | |
| cabhCapBase | 1.3.6.1.4.1.4491.2.4.3.1.1 | | | |
| U32 cabhCapTcpTimeWait | 1.3.6.1.4.1.4491.2.4.3.1.1.1 | Unsigned32 | read-write | This object is the maximum inactivity time to wait before
assuming TCP session is terminated. It has no relation to
the TCP session TIME_WAIT state referred to in [RFC793]. |
| U32 cabhCapUdpTimeWait | 1.3.6.1.4.1.4491.2.4.3.1.1.2 | Unsigned32 | read-write | The inactivity time to wait before destroying
CAP mappings for UDP. |
| U32 cabhCapIcmpTimeWait | 1.3.6.1.4.1.4491.2.4.3.1.1.3 | Unsigned32 | read-write | The inactivity time to wait before destroying
CAP mappings for ICMP. |
| INT cabhCapPrimaryMode | 1.3.6.1.4.1.4491.2.4.3.1.1.4 | INTEGER | read-write | The Primary Packet-handling Mode of the Portal Services
logical element (PS) of a CableHome compliant residential
gateway device. This object configures operation of the PS
packet handling functions.
When the value of this object is napt(1), the PS is
required to support the Network Address and Port
Translation (NAPT) process in accordance with the NAPT
requirements defined in IETF RFC 3022. When operating in
NAPT Primary Packet Handling Mode, the PS supports the
translation of multiple LAN-Trans IP addresses and their
TCP/UDP ports into a single WAN-Data IP address and its
TCP/UDP ports.
When the value of this object is nat(2), the PS is required
to support the Network Address Translation (NAT) process in
accordance with the NAT equirements defined in IETF RFC
3022. When operating in NAT Primary Packet Handling Mode,
the PS supports the translation of multiple LAN-Trans IP
addresses into the same number of unique WAN-Data IP
addresses.
When the value of this object is passthrough(3), the PS is
required to act as a transparent bridge in accordance with
IEEE 802.1D. When operating in Passthrough Primary Packet
Handling Mode, the PS does not translate network addresses,
and bridges all traffic between its LAN and WAN interfaces.
The PS MUST delete dynamically-created row entries from
the cabhCapMappingTable, i.e. those with
cabhCapMappingMethod = dynamic(2), when the value of
cabhCapPrimaryMode changes. The PS MUST NOT delete
statically-created row entries from the cabhCapMappingTable
where cabhCapMappingMethod = static(1), when the value of
cabhCapPrimaryMode changes. |
| T/F cabhCapSetToFactory | 1.3.6.1.4.1.4491.2.4.3.1.1.5 | TruthValue | read-write | Reading this object always returns false(2). When the
cabhCapSetToFactory object is set to true(1), the PS must
take the following actions:
1. Clear all entries in the cabhCapMappingTable and
cabhCapPassthroughTable.
2. Reset the following objects to their factory default
values:
cabhCapTcpTimeWait,
cabhCapUdpTimeWait,
cabhCapIcmpTimeWait,
cabhCapPrimaryMode |
| TIM cabhCapLastSetToFactory | 1.3.6.1.4.1.4491.2.4.3.1.1.6 | TimeStamp | read-only | The value of sysUpTime when cabhCapSetToFactory was
last set to true. Zero if never reset. |
| T/F cabhCapUpnpPortForwardingEnable | 1.3.6.1.4.1.4491.2.4.3.1.1.7 | TruthValue | read-write | This MIB is effective only when the PS is performing NAPT.
If this MIB object is set to false(2), the PS MUST disable
the UPnP WANIpConnection Service in the CableHome PS. If
this MIB object is set to true(1), the PS MUST enable the
WANIpConnection service in the PS. When the primary packet
handling mode of the PS is C-NAT (2) or Passthrough(3),
setting this MIB to true(1) MUST return InconsistentValue
error. |
| U32 cabhCapUpnpTimeWait | 1.3.6.1.4.1.4491.2.4.3.1.1.8 | Unsigned32 | read-write | The inactivity time to wait before destroying
CAP mappings created by UPnP control points. The
value of 0 indicates inactivity time wait of
infinity, i.e. a UPnP entry doesn�t get destroyed
based on inactivity period. |
| cabhCapMap | 1.3.6.1.4.1.4491.2.4.3.1.2 | | | |
| cabhCapMappingTable | 1.3.6.1.4.1.4491.2.4.3.1.2.1 | | not-accessible | This table contains IP address mappings between private
network addresses, or network addresses and port
numbers/ICMP Identifiers, assigned to devices on the
subscriber's home LAN, and network addresses, or network
addresses and port numbers/ICMP Identifiers on the WAN,
presumed to be on a separate subnetwork than the private
IP addresses. The CAP Mapping Table is used by the
CableHome Address Portal (CAP) function of the PS to make
packet forwarding decisions. |
| cabhCapMappingEntry | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1 | | not-accessible | List of the private IP (LAN) address - to - cable
operator assigned IP (WAN) address mappings stored
in the PS and used by the PS to make packet
forwarding decisions. |
| INT cabhCapMappingIndex | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.1 | INTEGER | not-accessible | The Index into the CAP Mapping Table. |
| IPt cabhCapMappingWanAddrType | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.2 | InetAddressType | read-create | The IP address type assigned on the WAN side. |
| IP cabhCapMappingWanAddr | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.3 | InetAddress | read-create | The IP address assigned by the cable operator's address
(DHCP) server, and comprising the WAN-side IP address
of the CAP Mapping tuple. This object is populated
either dynamically by LAN-to-WAN outbound traffic or
statically by the cable operator. |
| INE cabhCapMappingWanPort | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.4 | InetPortNumber | read-create | The TCP/UDP port number or ICMP Identifier
on the WAN side. A port number/Identifier of
0 indicates either a NAT or a DMZ mapping.
A non-zero port number/Identifier indicates
a NAPT mapping. If the value of
cabhCapMappingNumPorts MIB object is non-zero
this MIB represents a starting TCP/UDP port
number on the WAN side for which a mapping
entry is created. |
| IPt cabhCapMappingLanAddrType | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.5 | InetAddressType | read-create | The IP address type assigned on the LAN side. |
| IP cabhCapMappingLanAddr | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.6 | InetAddress | read-create | The IP address of the LAN-Trans IP Device. This object is
populated either dynamically as a result of LAN-to-WAN
outbound traffic or statically by the cable operator. |
| INE cabhCapMappingLanPort | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.7 | InetPortNumber | read-create | The TCP/UDP port number or ICMP Identifier
on the LAN side. A port number/Identifier
of 0 indicates either a DMZ mapping or a NAT
mapping. A non-zero port number/Identifier
indicates a NAPT mapping. If the value of
cabhCapMappingNumPorts MIB object is non-zero
then this MIB represents a starting TCP/UDP port
number on the LAN side for which a mapping
entry is created. |
| INT cabhCapMappingMethod | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.8 | INTEGER | read-only | Indicates how this mapping was created. Static means
that it was provisioned, and dynamic means that it
was handled by the PS itself. upnp (3) means that the
CAP mapping entry was created by some UPnP compliant
application. |
| INT cabhCapMappingProtocol | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.9 | INTEGER | read-create | The protocol for this mapping entry. The value
of other(1) represents a protocol other
than ICMP, TCP, and UDP. Thus, when the value
other(1) is specified for the cabhCapMappingProtocol
value of a CAP Mapping Table entry,
TCP, UDP or ICMP packets MUST NOT be forwarded even
if the WAN and LAN IP address and port tuple
of the packet matches with mapping entry.
The value of all(255) represents all protocol types. Thus,
when the cabhCapMappingProtocol value
all(255) is specified for an entry in the CAP Mapping
Table, traffic of all protocol types MUST be forwarded
accordingly f the WAN and LAN IP address and port tuple
in the packet matches the mapping entry. |
| ROW cabhCapMappingRowStatus | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.10 | RowStatus | read-create | The RowStatus interlock for the creation and deletion
of a cabhCapMappingTable entry. Changing the value of
the IP address or port number columns of the CAP
Mapping Table may have an effect on active traffic,
so the PS will prevent modification of this table's
columns and return an inconsistentValue error when
cabhCapMappingRowStatus object is active(1).
The PS must not allow RowStatus to be set to
notInService(2) by a manager.
A newly created row cannot be set to active(1) until
the corresponding instances of cabhCapMappingWanAddr,
cabhCapMappingLanAddr, and cabhCapMappingProtocol have
been set.
If the manager attempts to populate a row entry in
the table with a non-unique value for the combination
of cabhCapMappingWanAddr and range of WAN port(s)
(identified by cabhCapMappingWanPort to
cabhCapMappingWanPort + cabhCapMappingNumPorts �1),
or a non-unique value for the combination of
cabhCapMappingLanAddr and range of LAN port(s)
(identified by cabhCapMappingLanPort to
cabhCapMappingLanPort + cabhCapMappingNumPorts - 1),
the PS MUST prevent the creation of this row and return
an inconsistentValue error. This prevents creation of
entries with overlapping port ranges in the CAP table.
If the manager attempts to populate a row entry with
a zero value for cabhCapMappingWanPort and a non-zero
value for cabhCapMappingLanPort or a row entry with a
zero value for cabhCapMappingLanPort and a non-zero value
for cabhCapMappingWanPort, the PS MUST prevent the
creation of this row and return an inconsistentValue
error. This prevents creation of invalid NAT or NAPT entries.
If the manager attempts to populate a row entry with non-zero
values for both cabhCapMappingWanPort and
cabhCapMappingLanPort, but a zero value for
cabhCapMappingNumPorts, the PS MUST prevent
the creation of this row and return an inconsistentValue
error. This prevents creation of NAPT entries.
When Primary Packet-handling Mode is NAPT
(cabhCapPrimaryMode is napt(1)), provisioned rows can be
set to active(1) regardless of whether the value to which
cabhCapMappingWanPort, cabhCapMappingLanPort, and
cabhCapMappingNumPorts have been set is zero or nonzero.
When Primary Packet-handling Mode is NAT
(cabhCapPrimaryMode is nat(2)), a newly created row can
not be set to active(1) if a non-zero value have been set
for cabhCapMappingWanPort, cabhCapMappingLanPort and
cabhCapMappingNumPorts.
In NAPT Primary Packet-handling mode, a row
entry with zero values for cabhCapMappingWanPort,
cabhCapMappingLanPort, and cabhCapMappingNumPorts
objects represents a DMZ entry. |
| U32 cabhCapMappingNumPorts | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.11 | Unsigned32 | read-create | This object represents number of ports
available for port translation
on both LAN and WAN side.
When both cabhCapMappingWanPort and
cabhCapMappingLanPort are set to zero,
the PS MUST ignore this MIB object, and
such a row entry represents either a DMZ entry
(when primary packet handling mode is NAPT) or
a NAT entry (when primary packet handling mode is
NAT).
When a row entry is created with non-zero
values for cabhCapMappingWanPort,
cabhCapMappingLanPort, and cabhCapMappingNumPorts
the PS MUST translate range of ports on
the WAN side (identified by cabhCapMappingWanPort
to cabhCapMappingWanPort + cabhCapMappingNumPorts-1)
to range of ports on the LAN side (identified by
cabhCapMappingLanPort to cabhCapMappingLanPort +
cabhCapMappingNumPorts-1).
The PS MUST ignore this MIB for a CAP mapping
entry with the value of cabhCapMappingProtocol
equal to icmp(2). |
| STR cabhCapMappingRowDescr | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.12 | SnmpAdminString | read-create | A string value that can be used to describe
the purpose or attributes of the CAP Mapping
entry. |
| DAT cabhCapMappingCreateTime | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.13 | DateAndTime | read-only | For dynamic(2) and upnp(3) CAP mapping entries the PS MUST
set this MIB with date and time when the entry is created.
The PS MUST set the value of this MIB to zero valued
11-byte string for static CAP mapping entries. This MIB
object MUST NOT persist across the PS reboot. |
| DAT cabhCapMappingLastUpdateTime | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.14 | DateAndTime | read-only | The PS MUST set the value of this MIB
to zero valued 11 byte string for static
CAP mapping entries. For dynamic(2) CAP
Mapping entries, the PS MUST set the value
of this MIB to the value of cabhCapMappingCreateTime
For upnp(3) CAP mapping entries the PS MUST
set this MIB with date and time when the entry
is last updated. When the upnp(3)entry is first
created the PS MUST set this MIB with the value
of cabhCapMappingCreateTime MIB. This MIB object
MUST NOT persist across the PS reboot. |
| I32 cabhCapMappingDuration | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.15 | Integer32 | read-create | When a value greater than zero
is assigned to this object, the PS MUST
remove the CAP entry after the time
duration, represented by
this object, elapses starting from
cabhCapMappingLastUpdateTime.
When a value of 0 is assigned to this object,
the PS MUST retain the CAP mapping entry
until reboot or reset. The PS MUST retain
a CAP mapping entry with cabhCapMappingDuration
MIB set to 0 and cabhCapMappingMethod set
to static(1) across the reboots. The PS MUST
NOT retain a CAP mapping entry with
cabhCapMappingDuration MIB set to 0 and
cabhCapMappingMethod set to upnp(3) across
the reboots.
When a value of �1 is assigned for this
MIB the PS MUST ignore this MIB and
MUST remove the CAP mapping entries
based on TCP, UDP and ICMP inactivity
time-wait depending upon their protocol
type.
When the cabhCapMappingMethod object is
static(1), the default value for this object
is 0.
When the cabhCapMappingMethod object is
dynamic(2), the PS MUST set the value of
this object to �1.
When the cabhCapMappingMethod object is
upnp(3), the default value for this object
is -1. |
| IPt cabhCapMappingRemoteHostAddrType | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.16 | InetAddressType | read-only | The IP address type for a remote host on the WAN side. |
| IP cabhCapMappingRemoteHostAddr | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.17 | InetAddress | read-only | The IP address of the remote host for
a CAP mapping entry. The packet traversing
through the PS is either originated
from or is destined to this remote host.
The value of all zeros for this MIB object
indicates any IP address for a remote host. |
| T/F cabhCapMappingEnable | 1.3.6.1.4.1.4491.2.4.3.1.2.1.1.18 | TruthValue | read-only | This MIB allows the PS to enable or disable
a particular CAP mapping entry. When this MIB
is set to true(1) for a CAP mapping entry, the
PS MUST correctly route the traffic that
matches this entry. When this MIB is set to
false(2) for a CAP mapping entry, the PS MUST
NOT route the traffic that matches this entry. |
| cabhCapPassthroughTable | 1.3.6.1.4.1.4491.2.4.3.1.2.2 | | not-accessible | This table contains hardware addresses of LAN IP Devices
for which the PS will bridge traffic at OSI Layer 2. |
| cabhCapPassthroughEntry | 1.3.6.1.4.1.4491.2.4.3.1.2.2.1 | | not-accessible | List of hardware addresses of LAN IP Devices for which
the PS will bridge traffic at OSI Layer 2. |

MUST bridge traffic at OSI Layer 2. |
| ROW cabhCapPassthroughRowStatus | 1.3.6.1.4.1.4491.2.4.3.1.2.2.1.3 | RowStatus | read-create | The RowStatus interlock for the creation and
deletion of a cabhCapPassthroughTable entry.
Any writable object in each row can be modified
at any time while the row is active(1). |
