vdslLineSCMPhysBandCurrConstellationSize
Module: VDSL-LINE-EXT-SCM-MIB
OID (symbolic): VDSL-LINE-EXT-SCM-MIB::vdslLineSCMPhysBandCurrConstellationSize
OID (numeric): 1.3.6.1.2.1.10.228.1.1.2.1.5
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The current constellation size on this band.
What is vdslLineSCMPhysBandCurrConstellationSize?
This read-only value, from 0 to 16 expressed as log2, reports the current constellation size actually in use for this band on the physical VDSL line. Admins compare it against the configured profile value to see whether the line is achieving the intended bits-per-symbol encoding density. For example, a lower vdslLineSCMPhysBandCurrConstellationSize than requested in the profile indicates the line adapted down to a smaller constellation, likely due to noise on that band.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.228.1.1.2.1.5 snmpwalk -v2c -c public <target> VDSL-LINE-EXT-SCM-MIB::vdslLineSCMPhysBandCurrConstellationSize
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.10.228.1.1.2.1.5.1 snmpget -v2c -c public <target> VDSL-LINE-EXT-SCM-MIB::vdslLineSCMPhysBandCurrConstellationSize.1
