Setting an IP Address
5-10
5
CLI – This example configures an IPv6 gateway, specifies the management
interface, configures a global unicast address, and then sets the MTU.
Configuring an IPv6 General Network Prefix
The IPv6 General Prefix page is used to configure general prefixes that are
subsequently used on the IPv6 Configuration web page (see page 5-4) to specify
the network address portion of an interface address.
Command Usage
• Prefixes may contain zero-value fields or end in zeros.
• A general prefix holds a short prefix that indicates the high-order bits used in the
network portion of the address. Longer, more specific, prefixes can be based on
the general prefix to specify any number of subnets. When the general prefix is
changed, all of the more specific prefixes based on this prefix will also change.
Command Attributes
• General Prefix Name – The label assigned to the general prefix.
• Prefix Value – The high-order bits of the network address segment assigned to the
general prefix. The prefix must be formatted according to RFC 2373 “IPv6
Addressing Architecture,” using 8 colon-separated 16-bit hexadecimal values. One
double colon may be used in the address to indicate the appropriate number of
zeros required to fill the undefined fields.
• Prefix Length – A decimal value indicating how many of the contiguous bits (from
the left) of the address comprise the prefix (i.e., the network portion of the address).
