Troubleshooting at the Network Layer

IP (Internet Protocol)

The HiSpeed switch supports IP (Internet Protocol), a widely used Network Layer protocol used by devices to communicate across a network. IP utilizes a 32-bit address structure to identify the network and node number. The three primary classes of IP addresses are as follows:

Table 10-1.	IP address classes
Class	Range:	Subnet Mask:
Class A	0 - 127	255.0.0.0
Class B	128 - 191	255.255.0.0
Class C	192 - 223	255.255.255.0

Note: 127.0.0.1 is reserved for loopback testing.
