X In the “Access Mode” column, you specify whether this computer can
access the device with the read password (access mode “readOnly”) or
with the read/write password (access mode “readWrite”).
Note: The password for the “readOnly” access mode is the same as the
SNMPv3 password for read access. The password for the “readWrite”
access mode is the same as the SNMPv3 password for read/write
access. When you change one of the passwords, the device
automatically synchronizes the corresponding password for SNMPv3
(see on page 42 “Password / SNMPv3 access“).
X You can activate/deactivate this table entry in the “Active” column.
Note: If you have not activated any row, the device does not apply any
access restriction with regard to the IP addresses.
X The “Create entry” button enables you to create a new row in the table.
X With “Delete entry” you delete selected rows in the table.
Note: The row with the password currently in use cannot be deleted or
changed.
