docsDrfDownstreamCapabBandwidth
Module: DOCS-DRF-MIB
OID (symbolic): DOCS-DRF-MIB::docsDrfDownstreamCapabBandwidth
OID (numeric): 1.3.6.1.4.1.4491.2.1.23.1.3.1.2
Node type: OBJECT-TYPE
Type: Bits
Access: read-only
Description: The QAM channel Bandwidth capabilities. 'qamDependency' BIT set to '1' indicates the QAM channel bandwidth value has dependencies with other QAM channels as indicated in docsDrfGroupDependencyTable.
'chan6Mhz' set to '1' indicates 6 MHz channel width support. 'chan8Mhz' set to '1' indicates 8 MHz channel width support.
When 'qamDependency' BIT is set to '1', a set to the channel bandwidth PHY parameter of a QAM channels in a dependency group (with docsDrfGroupDependencyType set to docsDrfPhyParamSameValue), sets the same channel bandwidth value to all QAM channels in the dependency group.
What is docsDrfDownstreamCapabBandwidth?
This BITS value indicates the QAM channel's bandwidth capabilities: whether bandwidth has cross-channel dependencies (qamDependency) and whether 6 MHz (chan6Mhz) or 8 MHz (chan8Mhz) channel widths are supported. An admin reads this before provisioning channel width, because when qamDependency is set, changing the bandwidth of one channel in a same-value dependency group applies that same bandwidth to every channel in the group. A device reporting chan6Mhz and qamDependency both set means selecting 6 MHz on this channel will push 6 MHz onto its dependency-group siblings too.
