Vigor2860
After applying 3.9.1 I am no longer receiving:
Rec rate at 1.3.6.1.2.1.10.94.1.1.4.1.2.4
Tran rate at 1.3.6.1.2.1.10.94.1.1.5.1.2.4

Other metrics such as SNR at 1.3.6.1.2.1.10.94.1.1.3.1.4.4 are still there.

Any clues ?

Apparently this is a recent change for better overall SNMP standard adherence.

The VDSL and ADSL OIDs have been updated to work with standardised MIB definitions for xDSL. Instead of the previous layout which had them both at the ADSL OID value - 1.3.6.1.2.1.10.94.1.1.[4/5].1.2.4

This is now changed to the standardised OID for VDSL2 connections:
1.3.6.1.2.1.10.251.1.2.2.1. xdsl2ChStatusActDataRate.ifIndex.inbound
1.3.6.1.2.1.10.251.1.2.2.1. xdsl2ChStatusActDataRate.ifIndex.outbound

Inbound speed: 1.3.6.1.2.1.10.251.1.2.2.1.2 + ifIndex + .2
Outbound speed: 1.3.6.1.2.1.10.251.1.2.2.1.2 + ifIndex + .1

Documentation updates should be following soon as well, I'll see if something can be added into the firmware release notes about it, since I'm not sure this change was noticed with this firmware version.

Interesting that the other values are still at .94., that doesn't seem very consistent.
I don't have a Vigor 2860 connected up to xDSL to check, do you see the SNR value & other metrics duplicated at .251. or only on .94.?

Thank you for the information on the SNMP change.
If the SNR info has been moved to .251. I cannot find it

Also I can only find the downstream SNR. Is the upstream SNR available through SNMP?
The reason being is that I have an ongoing line quality issue with Openreach (line failures every 20 minutes for five months) and so have had to record connection speed and SNR but it is commonly the outbound SNR which falls through the floor and I have yet to find it via SNMP.

I can only test an ADSL connection with the 2865 right now, that shows the upstream SNR on .1.3.6.1.2.1.10.94.1.1.2.1.4.4 and the upstream attenuation on .1.3.6.1.2.1.10.94.1.1.2.1.5.4

Hi

I have never ever found the uplink snr, I dont think from performing snmpwalk it is there.
As for the 'enhancement', loss of capability is not!!
The list of supported snmp is here

Not sure there is an updated MIB.

BTW Draytek, your competitors supply this data, so on the next corporate HW review we may be moving, your shout
