请教stp问题

s7506和下级s3110均为级连口报拓扑改变，请教这个是配置有问题吗 %Dec 30 14:34:41:497 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/1 was notified of a topology change. %Dec 30 14:34:42:059 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/23 was notified of a topology change. %Dec 30 14:34:42:060 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/16 was notified of a topology change. %Dec 30 14:34:42:060 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/1 was notified of a topology change. %Dec 30 14:34:42:720 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/23 was notified of a topology change. %Dec 30 14:57:14:399 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/11 was notified of a topology change. %Dec 30 14:57:15:335 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/16 was notified of a topology change. %Dec 30 14:57:15:773 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=4; Instance 0's port GigabitEthernet4/0/23 was notified of a topology change. %Dec 30 14:57:15:791 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/1 was notified of a topology change. %Dec 30 14:57:16:309 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/16 was notified of a topology change. %Dec 30 14:57:16:309 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/1 was notified of a topology change. %Dec 30 14:57:16:709 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/23 was notified of a topology change. %Dec 30 14:57:16:709 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/13 was notified of a topology change. %Dec 30 14:57:16:960 2020 hexin STP/6/STP_NOTIFIED_TC: -Slot=2; Instance 0's port GigabitEthernet2/0/23 was notified of a topology change.
