SNMP Requests to ethernetinterfaces does not match (Cisco C9200-24T-4G)

[MarcMattheis6124]

Good Morning,

I need support for the following issue at SNMP requests, please:

The request (ifOperStatus) to the OID 1.3.6.1.2.1.2.2.1.8 gives 40 interfaces back, more than existing (at C2950G)
The state of the interfaces is not correct, many ports which are up are displayed as down as the answer of the snmp-request. 

The request to a specific ethernetport for example Gigabit Port 4 (OID: 1.3.6.1.2.1.2.2.1.8.4) gives down back, but the port is up and is blinking at the switch.

Could you please give me an advice how to solve this issue?  

used hardware:

C9200-24T-4G-E V01, SoftwareVersion: 17.03.01

C2950G-24EI

 - I would advice to correlate or check this output with a manual snmpwalk, it could be that the snmp manager software gets confused or                   does not support the modern switch fully and or correctly.

walk 1.3.6.1.2.1.2.2.1.2 to get the interface names, then you can do the correlation
