CLI Guide

Usage Information
• If two addresses are congured, delete an existing address before conguring a new address.
• If the last manually-congured global IPv6 address is removed using the “no” form of the command, the link-
local IPv6 address is removed automatically.
• IPv6 addresses on a single management interface cannot be members of the same subnet.
• IPv6 secondary addresses on management interfaces across platform must be members of the same subnet.
• IPv6 secondary addresses on management interfaces should not match the virtual IP address and should not
be in the same subnet as the virtual IP.
NOTE: Do not use the /128 prex length on physical or port channel interfaces. You can use the /128
prex length on loopback interfaces.
Example
Dell(conf)#interface tengigabitethernet x/x
Dell(conf-if-te-x/x)#ipv6 address ?
X:X:X:X::X IPv6 address
Dell(conf-if-te-x/x)#ipv6 address 2002:1:2::3 ?
<0-128> Prefix length in bits
Dell(conf-if-te-x/x)#ipv6 address 2002:1:2::3 /96 ?
Dell(conf-if-te-x/x)#ipv6 address 2002:1:2::3 /96
Dell(conf-if-te-x/x)#show config
ipv6 address eui64
Congure IPv6 EUI64 address conguration on the interface.
Syntax
ipv6 address {ipv6-address prefix-length} eui64
To disable IPv6 EUI64 address autoconguration, use the no ipv6 address {ipv6-address prefix-
length} eui64 command.
Parameters
ipv6-address prex-
length
Enter the IPv6 prex in the x:x:x:x::x format then the prex length in the /x format. The
range is from /0 to /128.
NOTE: The :: notation species successive hexadecimal elds of zeros.
Defaults none

Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information This command allows you to create an EUI64 address based on the specied prex and MAC address only. Prexes
may be congured on the interface using the ipv6 nd prefix command without creating an EUI64 address.
Example
Dell(conf)#int ten 0/4
Dell(conf-if-te-0/4)#ipv6 address 200:1::/64 eui64
Dell(conf)#int ten 0/6
Dell(conf-if-te-0/6)#ipv6 address 801:10::/64 eui64
