78-21485-01 Command Line Interface Reference Guide

Use the ipv6 address eui-64 command in Interface Configuration mode to 
configure an IPv6 address for an interface and enables IPv6 processing on the 
interface using an EUI-64 interface ID in the low order 64 bits of the address. 

To remove the address from the interface, use the no form of this command.

Syntax

ipv6 address 

ipv6-prefix

/

prefix-length

 eui-64

no ipv6 address [

ipv6-prefix

/

prefix-length

]

Parameters

•

ipv6-address—Specifies the IPv6 network assigned to the interface. This 
argument must be in the form documented in RFC4293 where the address 
is specified in hexadecimal using 16-bit values between colons.

•

prefix-length—The length of the IPv6 prefix. A decimal value that indicates 
how many of the high-order contiguous bits of the address comprise the 
prefix (the network portion of the address). A slash mark must precede the 
decimal value.

Default Configuration 

No IP address is defined for the interface.

Command Mode

Interface Configuration

User Guidelines

If the value specified for the 

prefix-length

 argument is greater than 64 bits, the 

prefix bits have precedence over the interface ID.

If the switch detects another host using one of its IPv6 addresses, it adds the IPv6 
address and displays an error message on the console.

Using the no IPv6 address command without arguments removes all 
manually-configured IPv6 addresses from an interface, including link local 
manually-configured addresses.
