255, and the allowed content is the ASCII characters from 32 to 126.
System Location:
The physical location of this node (e.g., telephone closet, 3rd floor). The allowed
string length is 0 to 255, and the allowed content is the ASCII characters from
32 to 126.
DHCP Enabled:
Enable DHCP snooping, Just tick the check box (

Fallback IP Address:
Users can configure the IP settings and fill in new values. Then, click
<Apply>
button to update.
Default: 192.168.1.77
Fallback Subnet Mask:
Subnet mask is made for the purpose to get more network address
because any IP device in a network must own its IP address, composed
of Network address and Host address, otherwise can’t communicate with
other devices each other. But unfortunately, the network classes A, B,
and C are all too large to fit for almost all networks, hence, subnet mask
is introduced to solve this problem. Subnet mask uses some bits from
host address and makes an IP address looked Network address, Subnet
mask number and host address. It is shown in the following figure. This
reduces the total IP number of a network able to support, by the amount
of 2 power of the bit number of subnet number (2^(bit number of subnet
number)).
Subnet mask is used to set the subnet mask value, which should be the
same value as that of the other devices resided in the same network it
attaches.

Assignment” in this manual.
Default: 255.255.255.0
