docsDrfChannelBlockTestIfIndex

Module: DOCS-DRF-MIB

OID (symbolic): DOCS-DRF-MIB::docsDrfChannelBlockTestIfIndex

OID (numeric): 1.3.6.1.4.1.4491.2.1.23.1.5.1.6

Node type: OBJECT-TYPE

Type: InterfaceIndexOrZero

Access: read-write

Description: The ifIndex of the QAM channel to perform the QAM channel test. A Set to a value that does not correspond to a QAM Channel within the Block channel returns error 'wrongValue'. A set to zero stops a current test execution.

What is docsDrfChannelBlockTestIfIndex?

This read-write InterfaceIndexOrZero value identifies which QAM channel within a channel block is the target of the test mode set in docsDrfChannelBlockTestType. A technician sets this to the ifIndex of the specific channel to test before triggering a test mode, and sets it back to zero to stop an active test. Setting this to ifIndex 12 (a QAM channel within the block) followed by docsDrfChannelBlockTestType set to allOff would target that test scope; supplying an ifIndex not belonging to the block returns a wrongValue error.
