Configuration Guidelines

When you configure an interface for IPv6, consider the following guidelines:

￿IPv6 only supports static routes.

￿Support for subnet router anycast addresses is not available.

￿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.
