Managing SwitchesConfiguring the Network3-24 59269-00 ASNetwork IP ConfigurationThe IP configuration identifies the switch on the Ethernet network, determineswhich network discovery method to use, and enables/disables the IPv4 and IPv6network addressing.IPv4 and IPv6 Addressing The 7.4 firmware supports the IPv4 and IPv6address families. An IPv4 address is 32 bits, and consists of four blocks ofdecimal numbers, with each block separated by a period. Each block can have upto three numbers. The single zero character displayed in a block represents allzeroes for that block. An example of an IPv4 address is 255.255.255.0. All fourblocks contain numbers. Table 3-5 describes the IPv4 and IPv6 configurationparameters.An IPv6 address allows for a much wider range of IP addresses assigned to ahost than an IPv4 address. An IPv6 address is 128 bits, and consists of eightblocks of hexadecimal numbers, with each block separated by a colon. Themaximum number of numerals in each block is four. One or more blocks with allzeroes are represented by two colon characters. The total number of blocksalways adds up to eight. To determine how many contiguous blocks contain onlyzeroes, subtract the number of populated blocks from eight. For example, theIPv6 address 2eee::49:24:7a:54:3434 is equivalent to2eee:0000:0000:49:24:7a:54:3434. The number of blocks containing zeroes inthis example is two (8-6=2).NOTE:Switches without IPv6 addressing enabled can not communicate with hostsor switches using the IPv6 addressing.Table 3-5. Network Properties — IP ConfigurationParameter DescriptionEnable Network InterfacesiPv4 Network Enable this option to permit the IPv4 addressing for-mat to be used anytime you are required to enter anIP address.CAUTION!Disabling this option will prevent you from using anIPv4 IP address for system services.
