For the\nshow command, the parameter name is to be used as a simple keyword without further arguments.\nThis instructs the tool to show the value of a given parameter. When no parameters are given,\nthe tool shows the complete maxrate configuration.\n\n\ntc-maxrate RATE-MAP\nRATE-MAP uses the array parameter syntax, see dcb(8) for details. Keys are TC indices,\nvalues are traffic rates in bits per second.  The rates can use the notation docu‐\nmented in section PARAMETERS at tc(8).  Note that under that notation, \"bit\" stands\nfor bits per second whereas \"b\" stands for bytes per second. When showing, the command\nline option -i toggles between using decadic and ISO/IEC prefixes.\n\n",
