SW161A Power Switch Maverick 1-Port User Guide
6. Security parameters configuration
Explanations about the masks settings:
∇
Each mask can be an IP address or a range of IP addresses.
∇
Each mask allows you to authorise or deny access to the Web server of the Power Switch to
specific addresses or to specific ranges of addresses.
∇
Each mask can be activated or deactivated (without function in this case).
∇
Each IP address consists of a series of four eight-bit numbers. The number 255 is used as a
wildcard, so it replaces all others.
∇
Masks are listed in order of descending priority; so Mask 1 has the highest priority.
∇
Masks have a cumulative effect; high priority masks supersede the effect of lower priority
masks.
