Module: DOCS-IF-M-CMTS-MIB
OID (symbolic): DOCS-IF-M-CMTS-MIB::docsIfMCmtsEqamDownstreamDeviceConfigPhyParamLock
OID (numeric): 1.3.6.1.4.1.4491.2.1.6.1.3.1.1.4
Node type: OBJECT-TYPE
Type: Bits
Access: read-write
Description: Administrative configuration of lock bits for EQAM channels PHY parameters.
A BIT set of this object is meaningful when the same BIT set in docsIfMCmtsEqamDownstreamDevicePhyParamLock is set to '0'. Therefore, a SET to this object when the entry value of docsIfMCmtsEqamDownstreamDevicePhyParamLock is set to '1' returns error 'wrongValue'.
When a PHY parameter BIT in this object is set to '1' the QAM channel PHY parameter in docsIfMCmtsDepiSessionConfigTable is locked for SNMP SETs returning error 'notWritable' on those attempts.
Sets to this object could be complex; as a rule of thumb, SNMP agents ignore bits that are not recognized (e.g., extensions). An attempt to set BITs while docsIfMCmtsEqamDownstreamDeviceConfigPhyParamLock is set to '1' is rejected and the error code 'wrongValue' is returned.
What is docsIfMCmtsEqamDownstreamDeviceConfigPhyParamLock?
A read-write companion bitmap to docsIfMCmtsEqamDownstreamDevicePhyParamLock: an admin sets a bit to 1 here to administratively lock that PHY parameter (frequency, modulation, etc.) against further SNMP SETs on this QAM channel, but only for bits the device itself hasn't already hard-locked. Setting a bit here while the corresponding hardware-lock bit is already 1 is rejected with 'wrongValue', so this object is really for voluntarily freezing settings, e.g. to stop accidental re-tuning of a live channel.
