Lets say I change the description of GigabitEthernet2/2 from TRUNK to ACCESS and then rediscover the device by using the tool you have integrated(see the picture below)
then it remains GigabitEthernet2/2-TRUNK, but it should change to GigabitEthernet2/2-ACCESS
The only chance to make this change work is delete this device and then discover it again.
If you have any questions, then please let me know.
