GigaX Series L2 Managed Switch User Guide 6 IP Addresses, Network Masks, and Subnets 6.1 IP Addresses This section pertains only to IP addresses for IPv4 (version 4 of the Internet Protocol). IPv6 addresses are not covered. This section assumes basic knowledge of binary numbers, bits, and bytes. For details on this subject, see Appendix 6. IP addresses, the Internet's version of telephone numbers, are used to identify individual nodes (computers or devices) on the Internet.
GigaX Series L2 Managed Switch User’s Guide Table 7. IP address structure Field1 Field2 Class A Network ID Host ID Class B Network ID Class C Network ID Field3 Field4 Host ID Host ID Following are examples of valid IP addresses: Class A: 10.30.6.125 (network = 10, host = 30.6.125) Class B: 129.88.16.49 (network = 129.88, host = 16.49) Class C: 192.60.201.11 (network = 192.60.
GigaX Series L2 Managed Switch User Guide 6.1.2 Network classes The three commonly used network classes are A, B, and C. (There is also a class D but it has a special use beyond the scope of this discussion.) These classes have different uses and characteristics. Class A networks are the Internet's largest networks, each with room for over 16 million hosts. Up to 126 of these huge networks can exist, for a total of over 2 billion hosts.
GigaX Series L2 Managed Switch User’s Guide 6.2 Subnet masks A mask looks like a regular IP address, but contains a pattern of bits that tells what parts of an IP address are the network ID and what parts are the host ID: bits set to 1 mean "this bit is part of the network ID" and bits set to 0 mean "this bit is part of the host ID." Subnet masks are used to define subnets (what you get after dividing a network into smaller pieces).
GigaX Series L2 Managed Switch User Guide The two extra bits in Field 4 can have four values (00, 01, 10, 11), so there are four subnets. Each subnet uses the remaining six bits in field4 for its host IDs, ranging from 0 to 63. Sometimes a subnet mask does not specify any additional network ID bits, and thus no subnets. Such a mask is called a default subnet mask. These masks are: Class A: Class B: Class C: 255.0.0.0 255.255.0.0 255.255.255.
GigaX Series L2 Managed Switch User’s Guide 7 Troubleshooting This section gives instructions for using several IP utilities to diagnose problems. A list of possible problems with suggestion actions is also provided. All the known bugs are listed in the release note. Read the release note before you set up the switch. Contact Customer Support if these suggestions do not resolve the problem. 7.1 Diagnosing problems using IP utilities 7.1.
GigaX Series L2 Managed Switch User Guide Figure 45. Using the ping utility If the target computer cannot be located, you will receive the message “Request timed out.” Using the ping command, you can test whether the path to the switch is working (using the pre-configured default LAN IP address 192.168.1.1) or another address you assigned. You can also test whether access to the Internet is working by typing an external address, such as that for www.yahoo.com (216.115.108.243).
GigaX Series L2 Managed Switch User’s Guide 7.1.2 nslookup You can use the nslookup command to determine the IP address associated with an Internet site name. You specify the common name, and the nslookup command looks up the name on your DNS server (usually located with your ISP). If that name is not an entry in your ISP’s DNS table, the request is then referred to another higher-level server, and so on, until the entry is found. The server then returns the associated IP address.
GigaX Series L2 Managed Switch User Guide 7.2 Replacing defective fans Turn off the power of the switch when you remove the fan module on the rear side of the switch. When any one of the switch fans (located on the rear panel) becomes defective, you can easily replace it following these steps. 1. Unlock the fan module by loosening the thumbscrew that secures it to the rear panel. Figure 47. Loosening the thumbscrew 2. Carefully pull the module out as shown. Figure 48.
