Jairo,
It looks like you don't have NetSight configured as a trap receiver on the switch. Please confirm that the correct VR is being used in the communication settings as mentioned in the article link below:

As mentioned in the article, for the Firmware Download MIB and Configuration MIB menus, you should select Script for both and the Device Family Definition File Name select ExtremeXOS - TFTP(VR-Mgmt)
If any changes are made, make sure to save them by clicking on the Save button near the top right corner of the screen.
Then try to add NetSight as a trap receiver again.
