User-specific security settings
On the WBM page, you can create new SNMPv3 users and modify or delete existing
users. The user-based security model works with the concept of the user name; in other
words, a user ID is added to every frame. This user name and the applicable security
settings are checked by both the sender and recipient.
Description
The page contains the following boxes:
User Name
Enter a freely selectable user name. After you have entered the data, you can no
longer modify the name.
