We need to update every community string in our Spectrum. Is there a way to do this without having to rediscover every device?
Release : 21.2, 22.2
You can right click the devices you want to update and go to Utilities -> Attribute Editor
From there you can add SNMP Community String and update the v3 string here with the updated username, or encryption.
Click apply and it will apply to all the devices.
Support suggests doing this in batches of ~500 at a time.
