Usage
Information
• If two addresses are configured, delete an existing address before configuring a
new address.
• If the last manually-configured 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.
Example
Dell(conf)#interface gigabitethernet 10/0
Dell(conf-if-gi-10/0)#ipv6 address ?
X:X:X:X::X IPv6 address
Dell(conf-if-gi-10/0)#ipv6 address 2002:1:2::3 ?
<0-128> Prefix length in bits
Dell(conf-if-gi-10/0)#ipv6 address 2002:1:2::3 /96 ?
<cr>
Dell(conf-if-gi-10/0)#ipv6 address 2002:1:2::3 /96
