Table 2-4
According to the scheme above, a subnet mask 255.255.255.0 will partition a network
with the class C. It means there will have a maximum of 254 effective nodes existed in this
sub-netted network and is considered a physical network in an autonomous network. So it
owns a network IP address which may looks like 168.1.2.0.
With the subnet mask, a bigger network can be cut into small pieces of network. If we
want to have more than two independent networks in a worknet, a partition to the network
must be performed. In this case, subnet mask must be applied.
For different network applications, the subnet mask may look like 255.255.255.240.
This means it is a small network accommodating a maximum of 15 nodes in the network.
Default gateway:
For the routed packet, if the destination is not in the routing table, all the traffic is put
into the device with the designated IP address, known as default router. Basically, it is a
routing policy. The gateway setting is used for Trap Events Host only in the switch.
For assigning an IP address to the switch, you just have to check what the IP address
of the network will be connected with the switch. Use the same network address and append
your host address to it.
