ipv6 address
Congures a global unicast IPv6 address on an interface.
Syntax
ipv6 address ipv6–address/prefix-length
Parameters ipv6-address/prex-length — Enter a full 128-bit IPv6 address with the network prex length, including the 64-bit
interface identier.
Defaults None
Command Mode INTERFACE
Usage Information
• An interface can have multiple IPv6 addresses. To congure an IPv6 address in addition to the link-local
address, enter the ipv6 address ipv6-address/mask command and specify the complete 128-bit IPv6
address. To congure a globally unique IPv6 address by entering only the network prex and length, use the
ipv6 address ipv6-prefix/prefix-length eui-64 command.
•
The no version of this command removes the IPv6 address on the interface.
Example
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ipv6 address 2111:dddd:0eee::22/64
Supported Releases 10.3.0E or later
ipv6 address autocong
Acquires global IPv6 addresses by using the network prex obtained from router advertisements.
Syntax
ipv6 address autoconfig
Parameters None
Defaults Disabled except on the management interface
Command Mode INTERFACE
Usage Information
• This command sets an interface in Host mode to perform IPv6 stateless auto-conguration by discovering
prexes on local links, and adding an EUI-64 based interface identier to generate each IPv6 address. The
command disables IPv6 forwarding. Addresses are congured depending on the prexes received in router
advertisement messages.
• The no version of this command disables IPv6 address autoconguration, resets the interface in Router mode,
and re-enables IPv6 forwarding.
Example
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# no switchport
OS10(conf-if-eth1/1/1)# ipv6 address autoconfig
OS10(conf-if-eth1/1/1)#
Supported Releases 10.3.0E or later
ipv6 address dhcp
Enables DHCP client operations on the interface.
Syntax
ipv6 address dhcp
