● 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 prefix length on physical or port channel interfaces. You can use the /128
prefix length on loopback interfaces.
Example
DellEMC(conf)# interface tengigabitethernet 1/2
DellEMC(conf-if-te-1/2)# ipv6 address ?
X:X:X:X::X IPv6 address
DellEMC(conf-if-te-1/2)# ipv6 address 2002:1:2::3 ?
<0-128> Prefix length in bits
DellEMC(conf-if-te-1/2)# ipv6 address 2002:1:2::3 /96 ?
<cr>
DellEMC(conf-if-te-1/2)# ipv6 address 2002:1:2::3 /96

!
interface TenGigabitEthernet 1/2
no ip address
ipv6 address 2002:1:2::3 /96
no shutdown
ipv6 address autoconfig
Configure IPv6 address auto-configuration for the management interface.
Syntax
ipv6 address autoconfig
To disable the address autoconfig operation on the management interface, use the no ipv6 address
autoconfig command.
Default Disabled

Usage Infomation
● SAA can configure up to two addresses. If any preferred prefix or valid timers time out, the
corresponding address are deprecated or removed. If an address is removed due to a time-out, an
address from the current unused prefix is used to create a new address. If there are no remaining
prefixes, the software waits to receive a new prefix from the RA.
● If auto-configuration is enabled, all IPv6 addresses on that management interface are auto-configured.
Manual and auto-configurations are not supported on a single management interface.
● Removing auto-configuration removes all auto-configured IPv6 addresses and the link-local IPv6
address from that management interface.
● IPv6 addresses on a single management interface cannot be members of the same subnet.
● IPv6 secondary addresses on management interfaces across a platform must be members of the same
subnet.
