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.
If you are changing one of the passwords, manually set the corresponding
password for SNMPv3 to the same value (see on page 42 “Password /
SNMPv3 access”). This way you ensure that you can also access with the
same password via SNMPv3.
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.
With “Create entry” you create a new row in the table.
With “Delete entry” you delete selected rows in the table.
Note: The device prevents deleting or changing the row with the password
currently in use.

mask bits
Binary notation of the IP address 172.168.23.20:
1010 1100 1010 1000 0001 0111 0001 0100
The binary representation of the mask with the IP address yields
an address range of:
1010 1100 1010 1000 0001 0111 0001 0000 bis
1010 1100 1010 1000 0001 0111 0001 1111
i.e.: 172.168.23.16 to 172.168.23.31
