docsIfExt2CmMscStatusMaximumScheduledCodes

Module: DOCS-IFEXT2-MIB

OID (symbolic): DOCS-IFEXT2-MIB::docsIfExt2CmMscStatusMaximumScheduledCodes

OID (numeric): 1.3.6.1.4.1.4491.2.1.5.1.2.1.1.4

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: Indicates the Maximum Scheduled Codes in use by the CM. The value is provided by the CMTS through a TLV value in the RNG-RSP message. Note that not all values from 4..128 are valid. A value of zero when docsIfExt2CmMscStatusSate is active(3) indicates there is no maximum scheduled codes value. This object should remain at zero when docsIfExt2CmMscStatusState is not active(3).

What is docsIfExt2CmMscStatusMaximumScheduledCodes?

This value reports the Maximum Scheduled Codes (MSC) the CMTS has assigned to a cable modem via the Ranging Response, valid from 4 to 128 or 0 when the modem isn't in the active MSC state. An admin reads it to confirm a modem was actually granted an MSC limit and to compare it against the CMTS-side minimum configured in docsIfExt2CmtsUpChannelMSCMinimumValue. A modem showing 32 here has been assigned 32 as its scheduled-code ceiling by the CMTS.
