Configuration Guidelines

© Copyright IBM Corp. 2011
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.
