Switch configuration Analysis

[fan.yang]

Hi guys:

I am the guy who has the Trunk problem last week. Finally, it looks the trunk port is working. But I still have some problem about this switch. I take some screen of the port/Vlan setting and the log message.

Can someone let me know what is the problem?

Hi

I think the port 1/7 is an access switch, right? apparently you have BPDU Guard enable on it also

On port 19/20 there is a native vlan mismatch, are they trunks? by default the vlan 1 is the native vlan (is not the best practice) and it should be the same on both ends.

What do you have connected there?
