Chapter 5 Managing Switches 139
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 represente d
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.
TABLE5-6 Network Properties- IP Configuration
Parameter Description
Enable Network Interfaces
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 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.
