ipv6 address eui-64

This command configures an IPv6 address for an interface using an EUI-64 interface ID in the low order 64 bits and enables IPv6 on the interface. Use the no form without any arguments to remove all manually configured IPv6 addresses from the interface. Use the no form with a specific address to remove it from the interface.

Syntax

ipv6 address ipv6-prefix/prefix-length eui-64

no ipv6 address [ipv6-prefix/prefix-length eui-64]

•ipv6-prefix- The IPv6 network portion of the address assigned to the interface. 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 contiguous bits (from the left) of the address comprise the prefix (i.e., the network portion of the address).

Default Setting

No IPv6 addresses are defined

Command Mode

Interface Configuration (VLAN)

Command Usage

•If a link local address has not yet been assigned to this interface, this command will dynamically generate a global unicast address and a link-local address for this interface. (The link-local address is made with an address prefix of FE80 and a host portion based the switch’s MAC address in modified EUI-64 format.)

•Note that the value specified in the ipv6-prefix may include some of the high-order host bits if the specified prefix length is less than 64 bits. If the specified prefix length exceeds 64 bits, then the network portion of the address will take precedence over the interface identifier.

•If a duplicate address is detected, a warning message is sent to the console.

•IPv6 addresses are 16 bytes long, of which the bottom 8 bytes typically form a unique host identifier based on the device’s MAC address. The EUI-64 specification is designed for devices that use an extended 8-byte MAC address. For devices that still use a 6-byte MAC address (also known as EUI-48 format), it must be converted into EUI-64 format by inverting the
