Network address and Host address; otherwise it can’t communicate with
other devices on the network. But, unfortunately, the network classes A,
B, and C are all too large to be manageable for almost all networks;
hence, subnet masking 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.
For more information, please also see the Section 2-1-4 “IP Address
Assignment” in this manual.
Default: 255.255.255.0
Fallback Gateway:
Sets an IP address for a gateway to handle those packets that do not
meet the routing rules predefined in the device. If a packet does not meet
the criteria for other pre-defined path, it must be forwarded to a default
router on a default path. This means any packet with undefined IP
address in the routing table will be sent to this device unconditionally.
Default: 192.168.1.254
Management VLAN:
Shows the management VLAN number.
Password:
Sets a password for this switch. Up to 16 characters are allowed in this
parameter. Any alphanumeric character is acceptable.
Default: admin
Inactivity Timeout (secs):
Sets the auto-logout timer. The valid value is 0 ~ 60 in the unit of minute
and a decimal point is not allowed. The value 0 means auto-logout timer
is disabled.
Default: 0
