  mtu  Set tag switching Maximum Transmission Unit

R6(config)#tag-switching ?

  atm             Configure ATM tagging options
  ip              Dynamic tag switching for IP
  request-tags    Specify valid downstream on demand destinations.
  tag-range       Tag range
  tdp             Tag Distribution Protocol

R6(config)#tag-switching ip ?
