CADANT-CMTS-LAYER2CMTS-MIB: View SNMP OID List / Download MIB

This MIB module contains the following information: 1) The concept of bridge groups and bridge ports 2) The policy governed the assigment of Internet Service Provider's subnet addresses per bridge group 3) Support for per bridge group spanning tree

The maximum number of bridge groups supported.

A table (and along with other supported tables) contains bridge group information. A bridge group is actually a Port-Vlan concept which consists of one or more E-ports and one or more D-ports. Each D-port includes its associated U-ports and is further subdivided into 3 sub-ports associated with different types of traffic. The CM sub-port carries traffic for the cable-modem itself. The CPEAUTH sub-port carries traffic for an authorized CPE behind a cable-modem. The CPEUNAUTH sub-port carries traffic for an unauthorized CPE behind a cable-modem. Initially, all ports belong to the OAM&P bridge group when a card is first provisioned. Bridge ports can only exist in one bridge group at a time and can be moved between them. Generally, the CPEAUTH sub-port on the D card would be in a bridge group with an E port that had access to the internet and the DHCP servers for the ISP used by the subscriber. The CM sub-port would be in a bridge group with an E port that had access to the DHCP servers and administrative controls for the MSO. The CPEUNAUTH sub-port would be in a bridge group that included access to a sign-on server.

A conceptual row containing information about different types of CMTS's broadcast domains and their configuration parameters.

Symbolic Name of the domain.

Control Object for row creation and deletion.

A table which contains read-only (status) information on bridge groups.

A conceptual row containing read-only information on bridge groups.

The bridge port that is the leader for this bridge group. If there are no bridge ports in this bridge group or there are multiple bridge ports in this bridge group but none of them make a clear leader, then cadBgLeaderBgpId is zero. Otherwise, it is the cadBgpId of the leader bridge port for this bridge group.

The mac address of the layer 2 entity associated with this bridge group. If there are no layer 2 entities associated with the bridge group, this value will be zero. In the case of a bundle, this will be the mac address of the bundle group leader.

The port number of the physical port containing this bridge port.

The type of this bridge port.

The bridge port which is the bundle leader. If this value is 0, then this port is not part of a bundle group. If this value is equal to its cadBgpId, then this port is the bundle leader for its group. Otherwise, this value must point to a valid bridge port.

The current mac address associated with the bridge port. Initially, this is the address associated with the MAC or Ethernet port, but can change as a result of bundling or sparing operations.

A table which contains status information on bridge group members.

A conceptual row containing status information on possible bridge group members.

The bridge group id to which this physical interface belongs.

The ifIndex of the layer 2 entity associated with the bridge group.

The portId of the port associated with the physical ifindex.

This variable controls whether broadcast ARP packets can be sent for an IPv4 address where there is no stored previous knowledge about a MAC/IP binding. The total number of broadcast ARPs to send before switching to the not-present state is limited by the cadAgingArpCacheSearchingMaxNumber variable.

This variable controls whether multicast NS packets can be sent for an IPv6 address where there is no stored previous knowledge about a MAC/IP binding. The total number of multicast NSs to send before switching to the not-present state is limited by the cadAgingNDCacheSearchingMaxNumber variable. If cadAgingNDCacheSearchingCableMulticast is false and there is no stored previous knowledge about a MAC/IP binding, the ND cache entry will transition immediately to the not-present state.

If there is no a single Subscriber Management Filter configured in the CMTS for the CM signaled UDC Group ID, the CMTS does not send UDC encodings to the CM.

This object is used to configure the C4 CMTS to accept maximum downstream frequency limit that conform with the EuroDOCSIS specifications (starndard range 112 MHz to 858 MHz), (extended 85 MHz to 999MHz) or to the DOCSIS specifications (standard 91 to 867 MHz), (extended range 57 MHz to 999 MHz). Changes to downstream frequency and width are verified against this object to ensure the C4 CMTS does not exceed the downstream spectrum limits imposed by this object. Attempting to decrease the downstream frequency spectrum implied by this object will fail if at least a single downstream is configured outside of the range for the new value. It is recommended this object be set during initial system setup.

This object is used to configure the C4 CMTS to accept minimum downstream frequency limit that conform with the EuroDOCSIS specifications (starndard range 112 MHz to 858 MHz), (extended 85 MHz to 999MHz) or to the DOCSIS specifications (standard 91 to 867 MHz), (extended range 57 MHz to 999 MHz). Changes to downstream frequency and width are verified against this object to ensure the C4 CMTS does not exceed the downstream spectrum limits imposed by this object. Attempting to increase the minimum downstream frequency limit implied by this object will fail if at least a single downstream is configured outside of the range for the new value. It is recommended this object be set during initial system setup.

This object is used to configure the C4 CMTS to accept upstream frequency ranges that conform with the EuroDOCSIS specifications (5 MHz to 65 MHz), to the extended range used in Japan (5 MHz to 55 MHz), or to the DOCSIS specifications (5 MHz to 42 MHz), or to the extended upstream range (5 MHz to 85 MHz). Changes to upstream frequency and width are verified against this object to ensure the C4 CMTS does not exceed the upstream spectrum limits imposed by this object. Attempting to narrow the upstream frequency spectrum implied by this object will fail if at least a single upstream is configured outside of the range for the new value.

Indicate if the transmit power extension (before registration) feature is enabled or not onthe CMTS. If set to 'true', the CMTS will populate TLV16 in the MDD message with the value of 1. If set to 'false', the CMTS will populate TLV16 in the MDD message with the the value of 0. The value in this MIB object is ignored if MTCM is disabled.

If set to 'true', the CMTS will populate TLV5.40 in the REG-RSP-MP message with the same value received in the REG-REQ-MP message (advertised CM capability). If set to 'false', the CMTS will respond with 0 in TLV5.40 of the REG-RSP-MP message. The value in this MIB object is ignored if MTCM is disabled

This object is used to potentially limit the number of channels within a CM's TCS. A value of 0 indicates the limit is determined by the CM's capabilities, configuration and operational status. When a non-zero value is specified and is smaller than the number of channels that are capable of residing within the CM's TCS, the number of channels within the CM's TCS will be restricted to the specified value.

This attribute indicates whether the CMTS is configured for 1x1 Energy Management Mode of operation on a per MAC Domain basis. If this attribute is set to 'true', the CMTS is configured for 1x1 Energy Management Mode of operation on this MAC Domain. If this attribute is set to 'false', the Energy Management 1x1 Mode of operation is disabled in the CMTS on this MAC Domain

The amount of time that an impaired OFDM profile will remain impaired before transitioning to good upon being notified that the CM can decode the profile. This provides some hysteresis for a profile to become stable before using the newly decodable profile. If set to a value of 0, then there is no hysteresis (no timer is started) and all profiles may transition to good immediately upon being notified that the CM can decode the profile.

If set to true, the CMTS will instruct the modem to try incrementally lower numbers of bonded channels instead of reverting immediately to single US bonded channel while registering a modem and a power shortfall or DRW violation is encountered.
