4. Configure the IPv6 address and mask address for the interface:
These commands configure the global prefix 2001:200:12d:1300::/64 and the
interface ID ::240:D0FF:FE48:4672, and enable IPv6 on interface e 1/5.
Note: The above procedure shows how to configure an IPv6 address with a
Syntax: enable [<password>]
Syntax: configure terminal
Syntax: [no] ipv6 address <ipv6-prefix>/<prefix-length>
You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values
between colons as documented in RFC 2373.
You must specify the <prefix-length> parameter in decimal value. A slash mark (/)
must follow the <ipv6-prefix> parameter and precede the <prefix-length> parameter.
IPv6 devices running Layer 2 software
To configure an IPv6 address to a device running Layer 2 software:
1. At the opening CLI prompt, enter enable.
2. Enter the following command at the Privileged EXEC level prompt (for example,
3. Access the configuration level of the CLI by entering the following command:
4. Configure the IP address and mask for the switch.
FastIron(config)# ipv6 address 2001:200:12D:1300:240:D0FF:FE48:4000:1/64
Note: The above procedure shows how to configure an IPv6 address with a
FastIron(config)#
FastIron(config)# int e 1/5
FastIron(config-if-e1000-1/5)# ipv6 address
2001:200:12D:1300:240:D0FF:FE48:4672:/64
manually configured Interface ID as the address for the interface. You could
also configure an IPv6 address with an automatically computed EUI-64
Interface ID as the address for the interface. Link-local IPv6 addresses are
also supported. For details, see the Configuration Guide.
FastIron> enable
#), then press Enter. This command erases the factory test configuration if still
present:
FastIron# erase startup-config
Attention:
Use the erase startup-config command only for new systems. If
you enter this command on a system you have already configured, the
command erases the configuration. If you accidentally do erase the
configuration on a configured system, enter the write memory command to
save the running configuration to the startup-config file.
Privileged EXEC Level:
FastIron# configure terminal
Global CONFIG Level:
