" }" + +.SH DESCRIPTION + +.B dcb maxrate +is used to configure and inspect maximum rate at which traffic is allowed to +egress from a given traffic class. + +.SH PARAMETERS + +The following describes only the write direction, i.e. as used with the +\fBset\fR command. For the \fBshow\fR command, the parameter name is to be used +as a simple keyword without further arguments. This instructs the tool to show +the value of a given parameter. When no parameters are given, the tool shows the +complete maxrate configuration. + +.TP +.B tc-maxrate \fIRATE-MAP +\fIRATE-MAP\fR uses the array parameter syntax, see +.BR dcb (8) +for details. Keys are TC indices, values are traffic rates in bits per second. +The rates can use the notation documented in section PARAMETERS at +.BR tc (8). +Note that under that notation, "bit" stands for bits per second whereas "b" +stands for bytes per second. When showing, the command line option +.B -i +toggles between using decadic and ISO/IEC prefixes. + +.SH EXAMPLE & USAGE + +Set rates of all traffic classes to 25Gbps, except for TC 6, which will +have the rate of 100Gbps: + +.P +# dcb maxrate set dev eth0 tc-maxrate all:25Gbit 6:100Gbit + +Show what was set: + +.P +# dcb maxrate show dev eth0 +.br +tc-maxrate 0:25Gbit 1:25Gbit 2:25Gbit 3:25Gbit 4:25Gbit 5:25Gbit 6:100Gbit 7:25Gbit + +.SH EXIT STATUS +Exit status is 0 if command was successful or a positive integer upon failure. + +.SH SEE ALSO +.BR dcb (8) + +.SH REPORTING BUGS +Report any bugs to the Network Developers mailing list +.B <netdev@vger.kernel.org> +where the development and maintenance is primarily done. +You do not have to be subscribed to the list to send a message there. + +.SH AUTHOR +Petr Machata <me@pmachata.org> |
