Module: DOCS-IF31-MIB
OID (symbolic): DOCS-IF31-MIB::docsIf31CmtsCmRegStatusUsProfileIucList
OID (numeric): 1.3.6.1.4.1.4491.2.1.28.1.3.1.3
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This attribute is a variable length series of hexadecimal octets where each series entry consists of the following fields (encoded in the following order):
- The ifIndex (4 octets) of the OFDMA channel where the Profile IUCs are assigned.
- The number or count of Data IUCs (1 octet with valid values of 1-2) assigned to this CM on that channel.
- The list of Data IUCs (1 octet each with valid values of 5, 6, 9-13) assigned to this CM on that channel.
The CCAP encodes each OFDMA channel in a CM's TCS as a separate n-octet entry in the UsProfileIucList.
Examples: a CM with a single OFDMA channel (ifIndex 36) and two assigned Data IUCs (5 and 6) would have a ProfileIdList value of 0x00000024020506. A CM with a 2 OFDMA channel bonding group each with one assigned Data IUC (IUC 5 on channel with ifIndex 34 and IUC 13 on channel with ifIndex 35) would have a UsProfileIucList value of 0x00000022010500000023010D).
Note: the CCAP MUST NOT include transitional IUCs or test IUCs in the UsProfileIucList.
Note that octet string lengths greater than 18 are optional.
This object is applicable to DOCSIS 3.1 modems but not to prior versions of DOCSIS modems. If the CM is a pre-DOCSIS 3.1 modem, the CMTS returns a zero length octet string.
What is docsIf31CmtsCmRegStatusUsProfileIucList?
A packed binary list, one entry per OFDMA upstream channel, showing which upstream Interval Usage Codes (Data IUCs 5, 6, or 9-13) the CMTS has assigned this modem for burst transmissions, each entry encoding the channel's ifIndex followed by the count and list of IUCs. This helps an admin see exactly which upstream modulation profiles are in use per channel for a given modem; it applies only to DOCSIS 3.1 modems and is empty for older ones.
