NAME         top

       ip-token - tokenized interface identifier support

SYNOPSIS         top

       ip token { COMMAND | help }

       ip token set TOKEN dev DEV

       ip token del dev DEV

       ip token get [ dev DEV ]

       ip token [ list ]

DESCRIPTION         top

       IPv6 tokenized interface identifier support is used for assigning
       well-known host-part addresses to nodes whilst still obtaining a
       global network prefix from Router advertisements. The primary
       target for tokenized identifiers are server platforms where
       addresses are usually manually configured, rather than using
       DHCPv6 or SLAAC. By using tokenized identifiers, hosts can still
       determine their network prefix by use of SLAAC, but more readily
       be automatically renumbered should their network prefix change
       [1]. Tokenized IPv6 Identifiers are described in the draft [1]:

   ip token set - set an interface token
       set the interface token to the kernel.

       TOKEN  the interface identifier token address.

       dev DEV
              the networking interface.

   ip token del - delete an interface token
       delete the interface token from the kernel.

       dev DEV
              the networking interface.

   ip token get - get the interface token from the kernel
       show a tokenized interface identifier of a particular networking
       device.  Arguments: coincide with the arguments of ip token set
       but the TOKEN must be left out.

   ip token list - list all interface tokens
       list all tokenized interface identifiers for the networking
       interfaces from the kernel.
