Description
Since upgrading some Cisco ASR9010 Routers to Cisco IOS-XR 7.9.21, we've noticed that non-DOM supported transceivers (i.e. copper) now have voltage, current & power sensors. See the attached screenshot. This is creating a lot of alerts.
I believe this is similar to issue OBS-3335.
Thoughts?

As I see in snmp output, this interfaces reports entPhysicalVendorType as cevSFP10GSR:
entPhysicalDescr.847355804 = 1000BASE-T SFP (NEBS 3), UTP, 100m
|
entPhysicalVendorType.847355804 = cevSFP10GSR
|
entPhysicalContainedIn.847355804 = 847250123
|
|
|
entPhysicalClass.847355804 = module
|
entPhysicalParentRelPos.847355804 = 0
|
entPhysicalName.847355804 = GigabitEthernet104/0/0/16
|
entPhysicalHardwareRev.847355804 = V02
|
entPhysicalFirmwareRev.847355804 =
|
entPhysicalSoftwareRev.847355804 =
|
entPhysicalSerialNum.847355804 = MTC203606EG
|
entPhysicalMfgName.847355804 = CISCO-METHODE
|
entPhysicalModelName.847355804 = SFP-GE-T
|
entPhysicalAlias.847355804 = ASSTAL
|
entPhysicalAssetID.847355804 = ASSTID-1
|
entPhysicalIsFRU.847355804 = true
|
this type corresponds to
-- 10GBASE-SR SFP+ Module for MMF

It seems you use unsupported modules which incorrectly report their type.
By first, you need write Cisco TAC about firmware issue. This is very hard track all vendor errors after update firmwares..
General questions and device support can be discussed in our Discord channel, click here to join.
Please make and attach additional information about the device:
- full snmp dump from device:
snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -Ih -ObentxU <hostname> .1 > myagent.snmpwalksnmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -Ih -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalkIf device not support SNMP version 2c, replace -v2c with -v1.
- If you have problems with discovery or poller processes, please do and attach these debugs:
./discovery.php -d -h <device>./poller.php -d -h <device>
- additionally attach device and/or vendor specific MIB files

I not sure that this is correct, without real system or snmpdump I can't check this.
Probably fixed in r13812.
Note, this fix is in rolling updates now: https://docs.observium.org/updating/#switch-between-rolling-and-stable-trains
