mdustats - MDU traffic statistics
mdustats [options] [device] [device] [...]
Collect and display MDU traffic statistics using the Qualcomm Atheros vendor specific VS_MDU_TRAFFIC_STATS message.
This program is part of the Qualcomm Atheros Powerline Toolkit. See the plc man page for an overview and installation instructions.
-c command
An integer indicating the type
of statistics to be collected and reported. Permitted values
are 0 through 255 decimal but only 4
through 15 are valid at this time. This option is
mandatory because the default value of 0 is invalid.
4 - retrieve traffic statistics on the slave side
5 - retrieve traffic statistics (master TX/RX) collected on
the master side
6 - retrieve traffic statistics (slave TX/RX) collected on
the master side
7 - retrieve traffic statistics (master/slave TX/RX)
collected on the master side
8 - clear traffic statistics on the slave side
9 - clear traffic statistics (master TX/RX) colleted on the
master side
10 - clear traffic statistics (slave TX/RX) collected on the
master side
11 - clear traffic statistics (master/slave TX/RX) collected
on the master side
12 - retrieve then clear traffic statistics collected on the
slave side
13 - retrieve then clear traffic statistics (master TX/RX)
collected on the master side
14 - retrieve then clear traffic statistics (slave TX/RX)
collected on the master side
15 - retrieve then clear traffic statistics (master/slave
TX/RX) collected on the master side
-s session
The session identifier used to associate request/confirm message pairs. Valid identifiers are 0 through 255. The default is 0.
-t milliseconds
Read timeout in milliseconds. Values range from 0 through UINT_MAX. This is the maximum time allowed for a response. The default is shown in brackets on the program menu.
-u unit
The slave unit number. This is the same as the slave Terminal Equipment Identifier or TEI. Valid unit numbers are 0 through 255. Unit 0 is the default. This option is ignored when option -c specified any of the "slave side" commands 4, 8 or 12.
|
-v |
Print additional information on stdout. | ||
|
-x |
Cause the program to exit on the first error instead of continuing with remaining iterations, operations or devices. Normally, the program reports errors and moves on to the next operation, iteration or device depending on the command line. |
-?,--help
Print program help summary on stdout. This option takes precedence over other options on the command line.
-?,--version
Print program version information on stdout. This option takes precedence over other options on the command line. Use this option when sending screen dumps to Atheros Technical Support so that they know exactly which version of the Linux Toolkit you are using.
|
device |
The Ethernet hardware address of some powerline device. More than one address may be specified on the command line. If more than one address is specified then operations are performed on each device in turn. The default address is local. as explained in the DEVICES section. |
Powerline devices use Ethernet hardware, or Media Access Control (MAC), addresses. Device addresses are expressed as 12 hexadecimal digits (0123456789ABCDEFabcdef) in upper, lower or mixed case. Individual octets may be separated by colons, for clarity, but not all octets need to be seperated. For example, "00b052000001", "00:b0:52:00:00:01" and "00b052:000001" are valid and equivalent.
These symbolic addresses are recognized by this program and may be used instead of the actual address value.
|
all |
Equivalent to "broadcast", described next. |
broadcast
A synonym for the standard Ethernet broadcast address, FF:FF:FF:FF:FF:FF. All devices, whether local, remote or foreign will respond to this address.
|
local |
A synonym for the Qualcomm Atheros vendor specific Local Management Address (LMA), 00:B0:52:00:00:01. All local Atheros devices will recognize this address but remote and foreign devices will not. A remote device is any device at the far end of a powerline connection. A foreign device is any device not manufactured by Atheros. |

The following example collects and displays MDU traffic statistics on the slave side of the local device because option -c is 4. The local device is implicit because no device is specified on the command line.
# mdustats -c 4
The next example collects and displays MDU traffic statistics for slave 2 on the master side of device 00:b0:52:9F:E0:14 because option -c is 5 and option -s is 2. The master device is explicit in this example.
# mdustats -c 5 -u 2 00b0529FE014
