Module: DOCS-IFEXT2-MIB
OID (symbolic): DOCS-IFEXT2-MIB::docsIfExt2CmMscStatusIUC2Control
OID (numeric): 1.3.6.1.4.1.4491.2.1.5.1.2.1.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The CM usage of IUC2 when MSC is enabled: noIUC2(1): CM usage of IUC2 is prohibited limitedIUC2(2): CM is allowed to use IUC2 as long as the CM does not exceed MSC freeIUC2(3): CM is allowed to use IUC2 without regard for MSC. With limitedIUC2(2), there may be cases where a CM cannot ensure that the use of IUC2 would not exceed MSC. In these cases, the CM MUST NOT use IUC2.
What is docsIfExt2CmMscStatusIUC2Control?
This read-write enumerated value controls how a cable modem may use Interval Usage Code 2 (IUC2) while MSC is enabled, with values noIUC2 (prohibited), limitedIUC2 (allowed as long as MSC isn't exceeded), and freeIUC2 (allowed without regard to MSC). An admin sets it to balance upstream scheduling flexibility against strict adherence to the modem's Maximum Scheduled Codes limit. Setting the value to limitedIUC2(2) lets the modem use IUC2 opportunistically but forces it to stop rather than exceed its MSC allotment.
