What is HSTP in Cisco and what does this log means?

Hello Engineers & Professionals,

Everytime I check my switch logs, I am seeing the weired logs.

Can anyone explain what this logs mean, and how to make it right?

Another thing is 'HSTP'.  This switch has configured pvst protocol.

For your information, interface vlan 1 has no ip address and shutdown status for now. (I am not sure SVI config is related or not)

Your reply is definately precious to me. Thank you.

 - Not an easy one, for the time being , make sure all trunks are operating as intended (show interfaces trunk ) and avoid settings as switchport mode dynamic desirable , for the time being. Or you may want to post the running-config with sensitive information cloaked

Thank you Marce1000,

When I checked the trunk ports of the switches, one of trunk port configured switchport access with trunk mode.

so I get rid of cli (no switchport access vlan #) and leave it only trunk mode.

Let me check the status for couple of hours. 

Thank you very much!
