DHCP Server: Shows the IP address of the DHCP server. The default is 0.0.0.0.
Lease Time Left: Shows the lease time left for the DHCP client.
Device Name: Set a special name for this switch. Up to 16 characters are allowed in this parameter. Any alphanumeric characters
and the null character are acceptable.
and the null character are acceptable.
Default: Giga Switch
DHCP Enabled: Enable DHCP snooping, Just tick the check box
√ to enable it. The default is disable.
Fallback IP Address: Users can configure the IP settings and fill in new values. Then, click on the “Apply” button to update. The
default is 192.168.1.1.
default is 192.168.1.1.
Fallback Subnet Mask: Subnet mask is used to create more network addresses, because any IP device in a network must own its
IP address, which is composed of a network address and a host address. Otherwise, the device can’t communicate with other
devices. Unfortunately, the network classes A, B, and C are all too large to fit for almost all networks, so subnet mask is used to
solve this problem. Subnet mask uses some bits from the host address and makes an IP address resemble a network address,
subnet mask number, and host address. This reduces the total IP number that a network can support, exponentially, by a power
of 2 of the bit number of subnet number (2

Subnet mask is used to set the subnet mask value, which should be the same value as that of the other devices residing in the
same network it attaches to. For more information, see Section 3.1.4, “Address Assignment” in this manual. The default is
255.255.255.0.

255.255.255.0.
Fallback Gateway: Set 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 another pre-defined path, it must be forwarded to a default router on a default
path. This means any packet with an undefined IP address in the routing table will be sent to this device unconditionally. The
default is 192.168.1.254.

default is 192.168.1.254.
Management VLAN: Show the management VLAN number.
Password: Set a password for this switch. Up to 16 characters are allowed in this parameter. Any alphanumeric character is

acceptable. The default password is “admin.”
Inactivity Timeout (secs): Set the auto-logout timer. The valid value is 0–60 in minutes and a decimal point is not allowed. The
value 0 means auto-logout timer is disabled. The default is 0.
value 0 means auto-logout timer is disabled. The default is 0.
5.2.2 Port Configuration
Function name: Port Configuration
Function description: Port Configuration sets the ports on the switch. You can set or reset the values for Mode and Flow Control.
You can also set the power-saving mode for switch power consumption.
