Steps to reproduce:

1. I use the Linux by SNMP Template from official git in Version 7.4-4
2. I Monitor a Dell OS10 switch which is a Debian 10 in the background
3. Now a Port is down, which it was before so I don't know why I got this message
4. in the frontend I see a mixed things, he said Port 1/1/1:4 is down (which is not true) and when I click on on it, it shows Port 1/1/2:1 (it's down, but it is many month down)

Result:
