SNMP Value - Cisco Switch

[MTLTR]

Hello. I have a little problem with SNMP value on Cisco switch with Gigabit Ethernet ports.
Latest data in Zabbix Frontend shows different speeds on interfaces ( https://i.imgur.com/UdLHmVA.png )
SNMPWalk in my Zabbix Server shows also wrong speed ( https://i.imgur.com/ns8FK0w.png ).

Zabbix 4.2.6

How I can repair this so that each interface showed correctly? Thanks for your support.
Best regards.

The speed of the Gigabit Ethernet ports is dictated by the device plugged in on the other end. So if to Cisco switch Gi0/4 port is connected PC with 100MB ethernet card the speed will be changed to 100 MB as it is. Try it and see. You should see changes on Your Zabbix (use CISCO IOS SNMPv2 template) and if You go to problems You should see something like this:

Hello.
Thanks for the answer. I can't agree with your theory. SNMP on the port shows 10Mbps and the card of this computer has 1Gbps. This causes Zabbix alerts when it exceeds the 10Mbps threshold.
I have no idea for that anymore.
