General Configuration Steps

The IPv6 configuration on switches running software release K.13.01 includes global and per-VLAN settings. This section provides an overview of the general configuration steps for enabling IPv6 on a given VLAN and can be enabled by any one of several commands. The following steps provide a suggested progression for getting started.

The ICMP and Neighbor Discovery (ND) parameters are set to default values at the global configuration level are satisfactory for many applications and generally do not need adjustment when you are first configuring IPv6 on the switch.

In the default configuration, IPv6 is disabled on all VLANs.

1.If IPv6 DHCP service is available, enable IPv6 DHCP on the VLAN. If IPv6 is not already enabled on the VLAN, enabling DHCPv6 also enables IPv6 and automatically configures a link-local address using the EUI-64 format.

If IPv6 is not already enabled on the VLAN, enabling DHCPv6 causes the switch to automatically generate a link-local address. DHCPv6 does not assign a link-local address.

A DHCPv6 server can provide other services, such as the addresses of time servers. For this reason you may want to enable DHCP even if you are using another method to configure IPv6 addressing on the VLAN.

2.If IPv6 DHCP service is not enabled on the VLAN, then do either of the following:

•Enable IPv6 on the VLAN. This automatically configures a link-local address with an EUI- 64 interface identifier.

•Statically configure a unicast IPv6 address on the VLAN. This enables IPv6 on the VLAN and, if you configure anything other than a link- local address, the link-local address will be automatically configured as well, with an EUI-64 interface identifier.

3.If an IPv6 router is connected on the VLAN, then enable IPv6 address autoconfiguration to automatically configure global unicast addresses with prefixes included in advertisements received from the router. The device identifier used in addresses configured by this method will be the same as the device identifier in the current link-local address.
