Module: DOCS-IF-M-CMTS-MIB

OID (symbolic): DOCS-IF-M-CMTS-MIB::docsIfMCmtsCoreDownstreamPhyDependencies

OID (numeric): 1.3.6.1.4.1.4491.2.1.6.1.2.1.1.2

Node type: OBJECT-TYPE

Type: Bits

Access: read-only

Description: The PHY parameters being flagged in the DEPI session as DEPI TSID group dependencies. A value of all bits on zero indicates no TSID group dependencies for PHY parameters. If this object value is the zero length string , indicates no DEPI session is configured for the M-CMTS Downstream interface or the Downstream interface is of the type 'integrated'.

What is docsIfMCmtsCoreDownstreamPhyDependencies?

A bitmap showing which PHY settings (frequency, bandwidth, power, modulation, interleaver, J.83 annex, symbol rate, mute) this downstream channel shares with other channels in a DEPI TSID dependency group, per docsIfMCmtsEqamGroupDependencyTable. All-zero (the default) means no such grouping exists, so an admin can change, say, frequency on this channel alone without side effects; if a bit is set, changing that parameter here may ripple to sibling channels in the same group.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.6.1.2.1.1.2
