Network IP configuration
The IP configuration identifies the switch on the Ethernet network, determines which network discovery
method to use, and enables/disables the IPv4 and IPv6 network addressing.
IPv4 and IPv6 addressing
The 7.6 and later firmware supports the IPv4 and IPv6 address families. An IPv4 address is 32 bits and
consists of four blocks of decimal numbers, with each block separated by a period. Each block can have
up to three numbers. A single zero character displayed in a block indicates that the block consists of all
zeroes. An example of an IPv4 address is 255.255.255.0. All four blocks contain numbers. Table 11
describes the IPv4 and IPv6 configuration parameters.
An IPv6 address allows for a much wider range of IP addresses assigned to a host than an IPv4 address.
An IPv6 address is 128 bits, and consists of eight blocks of hexadecimal numbers, with each block
separated by a colon. The maximum number of numerals in each block is four. One or more blocks with all
zeroes are represented by two colon characters. The total number of blocks always adds up to eight. To
determine how many contiguous blocks contain only zeroes, subtract the number of populated blocks from
eight. For example, the IPv6 address 2eee::49:24:7a:54:3434 is equivalent to
2eee:0000:0000:49:24:7a:54:3434. The number of blocks containing zeroes in this example is two
(8-6=2).
NOTE: Switches without IPv6 addressing enabled can not communicate over Ethernet with hosts or
switches using the IPv6 addressing.
Table 11 describes the network IP configuration parameters.

Field Description
IPv4 Network Enable this option to permit the IPv4 addressing format to
be used anytime you are required to enter an IP address.
CAUTION: Disabling this option will prevent you from
using an IPv4 IP address for system services.
IPv6 Network Enable this option to permit the IPv6 addressing format to
be used anytime you are required to enter an IP address.
CAUTION: Disabling this option will prevent you from
using an IPv6 IP address for system services.
