What Is CABH-CDP-MIB?
CABH-CDP-MIB is a CableLabs specification MIB, part of the CableHome program and registered under clabProjCableHome, that models the CableHome DHCP Portal (CDP) function of a residential gateway (PS) device — the component running a DHCP server on the LAN side and a DHCP client on the WAN side to bridge subscriber home-network addressing with the cable operator's provisioning system. It exposes LAN lease-pool health via cabhCdpLanTransCurCount/Threshold/Action (current active LAN-Trans leases versus a configurable threshold and the action taken when it's exceeded), WAN-side DHCP address acquisition counts (cabhCdpWanDataIpAddrCount), and a factory-reset control (cabhCdpSetToFactory) that clears LAN address leases and restores DHCP server option defaults for LAN pool ranges, DNS/router/syslog addresses, lease time, and time-offset settings under cabhCdpServer. Since CableHome is a CableLabs interoperability specification rather than a single manufacturer's product, it's implemented across many residential-gateway vendors' PS devices rather than being device-specific. Monitoring it is useful for detecting LAN address-pool exhaustion and confirming DHCP server-side configuration on cable-operator-provisioned gateways, making the CABH-CDP-MIB MIB a common target when auditing CableHome-compliant deployments.
IPNetwork Monitor allows you to monitor SNMP objects defined in CABH-CDP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- CableLabs CableHome-compliant residential gateway (PS) devices, multiple manufacturers
Monitoring Examples
An operator polls cabhCdpLanTransCurCount against cabhCdpLanTransThreshold to see how close a residential gateway's DHCP lease pool is to exhaustion, and cabhCdpLanTransAction reporting noAssignment would confirm the PS is now refusing new LAN-Trans address assignments because the threshold was exceeded.
What Can Be Monitored
- current vs. threshold LAN-Trans DHCP lease count
- lease-threshold-exceeded action
- WAN-side DHCP address acquisition count
- DHCP server option defaults (DNS/router/syslog/lease time)
- factory-reset control state

| INT cabhCdpDaylightSavingTimeEnable | 1.3.6.1.4.1.4491.2.4.4.1.1.9 | INTEGER | read-write | This object allows a manager to configure the PS to adjust the current time of day based on Daylight Saving Time. If the value of this object is enabled(1), the PS adds 3600 seconds and the time offset specified by cabhCdpServerTimeOffsetSelection to the UTC time acquired from the time of day server to create the current time of day during Daylight Saving Time, and adds only the time offset specified by cabhCdpServerTimeOffsetSelection to the UTC time acquired from the time of day server during standard time. The PS is responsible for knowing the date and time of each transition between Daylight Saving Time and standard time. If the value of this object is disabled(2), the PS adds only the time offset specified by cabhCdpServerTimeOffsetSelection to the UTC time acquired from the time of day server. |

| PHY cabhCdpLanAddrClientID | 1.3.6.1.4.1.4491.2.4.4.1.2.1.1.3 | PhysAddress | read-create | The client's (i.e., LAN IP Device's) hardware address as indicated in the chaddr field of its DHCP REQUEST message. There is a one-to-one relationship between the hardware address and the LAN IP Device. This parameter is entered by the PS (CDP) when the CDS grants a lease to a LAN IP Device in the LAN-Trans realm and creates a row in this table. Alternatively this parameter can be created by the NMS through the CMP, when the NMS creates a new DHCP address reservation by accessing the cabhCdpLanDataAddrRowStatus object with an index comprised of a unique cabhCdpLanAddrIp and creating a row with a unique cabhCdpLanAddrClientID. |
| cabhCdpLanAddrEntry | 1.3.6.1.4.1.4491.2.4.4.1.2.1.1 | not-accessible | List of general parameters pertaining to LAN-Trans IP address reservations and leases. | |

| IP cabhCdpLanAddrIp | 1.3.6.1.4.1.4491.2.4.4.1.2.1.1.2 | InetAddress | not-accessible | The address assigned to the LAN IP Device. This parameter is entered by the CDP when the CDS grants a lease to a LAN IP Device in the LAN-Trans realm and creates a row in this table. Alternatively, this parameter can be entered by the NMS through the CMP, when the NMS creates a new DHCP address reservation. Each cabhCdpLanAddrIp in the table must fall within the range of IPs defined inclusively by cabhCdpLanPoolStart and cabhCdpLanPoolEnd. The PS must return an inconsistentValue error if the NMS attempts to create a row entry with a cabhCdpLanAddrIP value that falls outside of this range or is not unique from all existing cabhCdpLanAddrIP entries in this table. The address type of this object is specified by cabhCdpLanAddrIpType. |
| IPt cabhCdpLanAddrIpType | 1.3.6.1.4.1.4491.2.4.4.1.2.1.1.1 | InetAddressType | not-accessible | The type of IP address assigned to the LAN IP Device in the LAN-Trans Realm. |
| DAT cabhCdpLanAddrLeaseCreateTime | 1.3.6.1.4.1.4491.2.4.4.1.2.1.1.4 | DateAndTime | read-only | This is the date and time when the LAN IP lease was created (if it has not yet been renewed) or last renewed. This MIB object contains a zero valued 11 byte string when a reservation is created for a LAN IP address and it maintains this value until the LAN IP Device acquires its lease and cabhCdpLanAddrMethod becomes reservationActive(2). |
| DAT cabhCdpLanAddrLeaseExpireTime | 1.3.6.1.4.1.4491.2.4.4.1.2.1.1.5 | DateAndTime | read-only | This is the date and time when the LAN IP address lease expired or will expire. This MIB object contains a zero valued 11 byte string when a reservation is created for a LAN IP address and it maintains this value until the LAN IP Device acquires its lease and cabhCdpLanAddrMethod becomes reservationActive(2). |
| INT cabhCdpLanAddrMethod | 1.3.6.1.4.1.4491.2.4.4.1.2.1.1.6 | INTEGER | read-only | The IP allocation method indicated by this row. The value of mgmtReservationInactive(1) indicates an externally provisioned IP address reservation that has not yet been leased or that has an expired lease. This indicates an IP address lease reservation created either by an operator or a user. The value of mgmtReservationActive(2) indicates an externally provisioned IP address reservation that has an active lease. This indicates an IP address lease reservation created either by an operator or a user. The value of dynamicInactive(3) indicates an IP address that was once dynamically assigned to a LAN-Trans by the PS device but currently has an expired lease. The value of dynamicActive(4)indicates an IP Address that was dynamically assigned to a LAN-Trans device by the PS and has a current active lease. The value of psReservationInactive(5) indicates an IP address reservation created by some internal process of the PS and has not yet been leased or has an expired lease. The value of psReservationActive(6) indicates an IP address reservation created by some internal process of the PS that has an active lease. |
| ROW cabhCdpLanAddrRowStatus | 1.3.6.1.4.1.4491.2.4.4.1.2.1.1.8 | RowStatus | read-create | The RowStatus interlock for creation and deletion of row entries. The PS must not allow the NMS to set RowStatus to notInService(2). The PS must assign a RowStatus of notInService(2) to any new row entry created with a non-unique, cabhCdpLanAddrClientID value. The PS must assign a RowStatus of notReady(3) to any new row entry created without a cabhCdpLanAddrClientID. The PS will prevent modification of this table's columns and return an inconsistentValue error, if the NMS attempts to make such modifications while the RowStatus is active(1). |
| cabhCdpLanAddrTable | 1.3.6.1.4.1.4491.2.4.4.1.2.1 | not-accessible | This table is a list of LAN-Trans realm parameters. This table has one row entry for each allocated LAN-Trans IP address. Each row must have at least a valid cabhCdpLanAddrMethod, a cabhCdpLanAddrIpType, a unique cabhCdpLanAddrIp, and a unique cabhCdpLanAddrClientId value. Static/Manual address assignment: To create a new DHCP address reservation, the NMS creates a row with: an index comprised of a new cabhCdpLanAddrIp and its cabhCdpLanAddrIpType, a new unique cabhCdpLanAddrClientID, (an empty LeaseCreateTime and empty LeaseExpireTime,) and a cabhCdpLanDataAddrRowStatus of createAndGo(4). If the syntax and values of the new row - indicating a reservation - are valid, the PS must set cabhCdpLanAddrMethod to reservationInactive(1) and cabhCdpLanDataAddrRowStatus to active(1). When the PS grants a lease for a reserved IP, it must set the cabhCdpLanAddrMethod object for that row to reservationActive(2). When a lease for a reserved IP expires, the PS must set the corresponding row's cabhCdpLanAddrMethod object to reservationInactive(1). For row entries that represent lease reservations - rows in which the cabhCdpLanAddrMethod object has a value of either reservationInactive(1) or reservationActive(2) - the cabhCdpLanAddrIpType, cabhCdpLanAddrIp, cabhCdpLanAddrClientID, cabhCdpLanAddrMethod, and cabhCdpLanAddrHostName object values must persist across PS reboots. Dynamic address assignment: When the PS grants a lease for a non-reserved IP, it must set the cabhCdpLanAddrMethod object for that row to dynamicActive(4). When a lease for a non-reserved IP expires, the PS must set the corresponding row's cabhCdpLanAddrMethod object to dynamicInactive(3). The PS must create new row entries using cabhCdpLanAddrIp values that are unique to this table. If all cabhCdpLanAddrIp values in the range defined by cabhCdpLanPoolStart and cabhCdpLanPoolEnd are in use in this table, the PS may overwrite the cabhCdpLanAddrClientId of a row that has a cabhCdpLanAddrMethod object with a value of dynamicInactive(3) with a new cabhCdpLanAddrClientId value and use that cabhCdpLanAddrIp as part of a new lease. For row entries that represent active leases - rows in which the cabhCdpLanAddrMethod object has a value of dynamicActive(4) - the cabhCdpLanAddrIpType, cabhCdpLanAddrIp, cabhCdpLanAddrClientID, cabhCdpLanAddrMethod, and cabhCdpLanAddrHostName object values must persist across PS reboots. | |

| INT cabhCdpLanTransAction | 1.3.6.1.4.1.4491.2.4.4.1.1.4 | INTEGER | read-write | The action taken when the CDS assigns a LAN-Trans address and the number of LAN-Trans addresses assigned (cabhCdpLanTransCurCount) is greater than the threshold (cabhCdpLanTransThreshold) The actions are as follows: normal - assign a LAN-Trans IP address as would normally occur if the threshold was not exceeded. noAssignment - do not assign a LAN-Trans IP address. |
| U32 cabhCdpLanTransCurCount | 1.3.6.1.4.1.4491.2.4.4.1.1.2 | Unsigned32 | read-only | The current number of active leases in the cabhCdpLanAddrTable (the number of row entries in the table that have a cabhCdpLanAddrMethod value of reservationActive(2) or dynamicActive (4)). This count does not include expired leases or reservations not associated with a current lease. |
| INT cabhCdpLanTransThreshold | 1.3.6.1.4.1.4491.2.4.4.1.1.3 | INTEGER | read-write | The threshold number of LAN-Trans IP addresses allocated or assigned above which the PS generates an alarm condition. Whenever an attempt is made to allocate a LAN-Trans IP address when cabhCdpLanTransCurCount is greater than or equal to cabhCdpLanTransThreshold, an event is generated. A value of 0 indicates that the CDP sets the threshold at the highest number of addresses in the LAN address pool. |

| I32 cabhCdpSnmpSetTimeOffset | 1.3.6.1.4.1.4491.2.4.4.1.1.8 | Integer32 | read-write | This object is intended to be used in cases where the service provider's provisioning system serves devices in multiple time zones, or for other times when the service provider wants UTC time offset to be provisioned in a device other than from the ToD server or from the DHCP Server (in DHCP Option 2). This object allows a manager to set a value for UTC time offset. If DHCP Option 2 is not present in the DHCP ACK message, or if the value of DHCP Option 2 is null, and time offset information is not provided in the response received from the time of day server, the PS MUST add the value of cabhCdpServerTimeOffset to the UTC time acquired from the time of day server to create the current time of day. If the value of cabhCdpServerTimeOffsetSelection is useSnmpSetOffset(2), the PS adds the value of cabhCdpServerSnmpSetTimeOffset to the UTC time acquired from the time of day server to create the current time of day. If the value of cabhCdpServerTimeOffsetSelection is useDhcpOption2(1) the PS ignores cabhCdpServerSnmpSetTimeOffset. |
| INT cabhCdpTimeOffsetSelection | 1.3.6.1.4.1.4491.2.4.4.1.1.7 | INTEGER | read-write | This object selects the source to be used by the PS in determining the time offset to the time of day acquired from the time server. It is intended to be used in cases where the time zone information provisioned by the ToD server or DHCP Server (in DHCP Option 2) is different from the time zone where the provisioned device is physically located. Setting this object to useDhcpOption2(1) configures the PS to use the value of DHCP Option 2 from the DHCP ACK message for time of day offset. Setting this object to useSnmpSetOffset(2) configures the PS to use the value of cabhCdpServerSnmpSetTimeOffset for time of day offset, and to ignore DHCP Option 2. When the value of this object is changed the PS MUST immediately begin using the time offset specified by the value of this object, regardless of which time offset the PS was using before the update occurred. |

| I32 cabhCdpWanDataAddrRenewalTime | 1.3.6.1.4.1.4491.2.4.4.1.2.2.1.5 | Integer32 | read-only | This is the time remaining before the lease expires. This is based on DHCP Option 51. |
| ROW cabhCdpWanDataAddrRowStatus | 1.3.6.1.4.1.4491.2.4.4.1.2.2.1.6 | RowStatus | read-create | The RowStatus interlock for creation and deletion of row entries. Any writable object in a row can be modified at any time while the row is active(1). The PS must assign a RowStatus of notInService(2) to any new row entry created with a cabhCdpWanDataAddrClientId that is not unique within this table. |
| cabhCdpWanDataAddrTable | 1.3.6.1.4.1.4491.2.4.4.1.2.2 | not-accessible | This table contains WAN-Data address realm information. | |
| INT cabhCdpWanDataIpAddrCount | 1.3.6.1.4.1.4491.2.4.4.1.1.5 | INTEGER | read-write | This is the number of WAN-Data IP addresses the PS's CDC must attempt to acquire via DHCP. When this MIB object is incremented the CDC MUST immediately attempt to acquire additional WAN-Data IP addresses. When this MIB object is decremented the CDC MUST not renew the leases for the appropriate number of WAN-Data IP addresses. |
| cabhCdpWanDnsServerEntry | 1.3.6.1.4.1.4491.2.4.4.1.2.3.1 | not-accessible | List of cable network and Internet DNS servers. | |
| IP cabhCdpWanDnsServerIp | 1.3.6.1.4.1.4491.2.4.4.1.2.3.1.3 | InetAddress | read-only | This parameter indicates the IP address of a WAN DNS server. The type of this address is specified by cabhCdpWanDnsServerIpType. |
| IPt cabhCdpWanDnsServerIpType | 1.3.6.1.4.1.4491.2.4.4.1.2.3.1.2 | InetAddressType | read-only | This parameter indicates the IP address type of a WAN DNS server. |
| INT cabhCdpWanDnsServerOrder | 1.3.6.1.4.1.4491.2.4.4.1.2.3.1.1 | INTEGER | not-accessible | The order of preference for cable network and Internet DNS servers, as listed in DHCP option 6 (Domain Server). Any time the CDC receives valid IP address information within DHCP Option 6, as part of lease acquisition or renewal of a WAN-Man or WAN-Data IP, it must update this information into this table. As entries in DHCP Option 6 are listed in order of preference, the highest priority entry in DHCP Option 6 must correspond to the row with a cabhCdpWanDnsServerOrder with a value of 1. If DHCP Option 6 contains 1 valid IP address, the PS MUST update the row with a cabhCdpWanDnsServerOrder value of 1 and MUST NOT modify rows with cabhCdpWanDnsServerOrder values of 2 & 3 (if they exist). If DHCP Option 6 contains 2 valid IP addresses, the PS MUST update the rows with cabhCdpWanDnsServerOrder values of 1 and 2 and MUST NOT modify the row with cabhCdpWanDnsServerOrder value of 3 (if it exists). If DHCP Option 6 contains 3 valid IP addresses, the PS MUST update rows with cabhCdpWanDnsServerOrder values of 1, 2, and 3. Any DNS server information included in DHCP Option 6 beyond primary, secondary and tertiary will not be represented in this table. |
| cabhCdpWanDnsServerTable | 1.3.6.1.4.1.4491.2.4.4.1.2.3 | not-accessible | This table contains the IP addresses of cable network and Internet DNS servers, in the order of preference in which the PS's CNP will query them, when it cannot resolve a DNS query using local information. Entries in this table are updated with the information contained in DHCP Option 6, received during both the WAN-Man and WAN-Data IP acquisition processes. |
