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.
● 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.
ipv6 address
Configure an IPv6 address to an interface.
Syntax
ipv6 address {ipv6-address prefix-length}
To remove the IPv6 address, use the no ipv6 address {ipv6-address prefix-length}
command.
Parameters
ipv6-address
prefix-length
Enter the IPv6 address in the x:x:x:x::x format then the prefix length in the /x
format. The range is from /0 to /128.
NOTE: The :: notation specifies successive hexadecimal fields of zeros.
Defaults none

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
● 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.
NOTE: Do not use the /128 prefix length on physical or port channel interfaces. You can use the /128
prefix length on loopback interfaces.
