CN4093 Application Guide for N/OS 8.4
This section provides steps to configure IPv6 on the switch.
When you configure an interface for IPv6, consider the following guidelines:
 Support for subnet router anycast addresses is not available.
Interface 125/126 are reserved for IPv6 management.

 A single interface can accept either IPv4 or IPv6 addresses, but not both IPv4
and IPv6 addresses.
 A single interface can accept multiple IPv6 addresses.
 A single interface can accept only one IPv4 address.
 If you change the IPv6 address of a configured interface to an IPv4 address, all
IPv6 settings are deleted.
 A single VLAN can support only one IPv6 interface.
 Health checks are not supported for IPv6 gateways.
 IPv6 interfaces support Path MTU Discovery. The CPU's MTU is fixed at 1500
bytes.
Support for jumbo frames (1,500 to 9,216 byte MTUs) is limited. Any jumbo

frames intended for the CPU must be fragmented by the remote node. The
switch can re‐assemble fragmented packets up to 9k. It can also fragment and
transmit jumbo packets received from higher layers.
The following example uses IPv6 host mode to autoconfigure an IPv6 address for
the interface. By default, the interface is assigned to VLAN 1.
