In the default configuration, IPv6 operation is disabled on the switch. This section describes the general steps and individual commands for enabling IPv6 operation.

This chapter provides the following:

■general steps for IPv6 configuration

■IPv6 command syntax descriptions, including show commands

Most IPv6 configuration commands are applied per-VLAN. The exceptions are ICMP, ND (neighbor discovery), and the (optional) authorized-managers feature, which are configured at the global configuration level. (ICMP and ND for IPv6 are enabled with default values when IPv6 is first enabled, and can either be left in their default settings or reconfigured, as needed.) For more information on ICMP, refer to “ICMP Rate-Limiting” on page 8-2.For more on ND, refer to “Neighbor Discovery (ND) in IPv6” on page 2-9.

For a quick reference to all IPv6 commands available on the switch, refer to the “IPv6 Command Index” on page xii at the front of this guide.

Beginning with software release K.13.01, the switch is capable of operating in dual-stack mode, where IPv4 and IPv6 run concurrently on a given VLAN.
