NAME
plcstat - Qualcomm Atheros AR7x00 Link Statistics
SYNOPSIS
plcstat [options] [device] [...]
DESCRIPTION
The Atheros Device Statistics Utility polls a device and prints network and link
statistics in various formats suitable for use by other programs. This is a work in
progress so user feedback is encouraged. Link statistics are only valid between one
powerline device and another.
This program is part of the Qualcomm Atheros Powerline Toolkit. See the plc man page for
an overview and installation instructions.
COMMENTS
This program is identical to legacy program int6kstat but uses version 1 of the Qualcomm
Atheros VS_NW_INFO Atheros vendor-specific message. Older firmware versions may not
recognize this message version.
OPTIONS
-C Clear device link statistics using VS_LNK_STATS. Statistics are read and cleared
then displayed. The statistics that are read and displayed depend on options -d,
-p and -s but all link statistics are cleared.
-d direction
Return statistics for the specified direction using VS_LNK_STATS. Direction can be
0=tx, 1=rx, 2=both or "rx", "tx" or "both".
-e Redirects stderr messages to stdout. By convention status and error messages are
printed on stderr while primary program output is printed on stdout. This option
prints all output on stdout in cases where this is desired.
-i Select the host Ethernet interface. All requests are sent via this host interface
and only reponses received via this host interface are recognized. The default
interface is eth1 because most people use eth0 as their principle network
connection; however, if environment string "PLC" is defined then it takes
precedence over the default interface. This option then takes precedence over
either default.
-l count
Define the number of times that the command will be repeated for each device
specified. Normally, you will repeat operations on one device only.
-m Displays network membership information, as seen by one device, using VS_NW_INFO.
Use option -t for complete network topology seen by the local host.
-p peernode
Ethernet hardware address of the peer node for VS_LNK_STATS. This option is
required for all Link ID values except 0xFC. The default is 00:00:00:00:00:00.
-q Enter quiet mode. Progress messages are suppressed.
-s linkid
The Link ID for VS_LNK_STATS. Link ID values range from 0 through 255 but not all
values are accepted by the device firmware. Values may be expressed in decimal,
binary prefixed with "0b" or hexadecimal prefixed by "0x". Many valid values can
be expressed by name. Valid values are listed and explained under LINKID. The
default Link ID is 0xFC.
-t Display network topology using VS_SW_VER and VS_NW_INFO messages. This option is
similar to option -m but provides complete network topology plus device hardware
and firmware version. Topology is relative to the queried powerline device(s)
given on the command line. If no device is given explicitly, then it is tried to
determine all local devices (you can also use local instead). However, this can
fail if you have the local powerline device(s) not directly connected but via a
switch which does not broadcast the Qualcomm Atheros vendor specific Local
Management Address (LMA) to all ports.
-v Enter verbose mode. All Etherenet frames sent or received by the program are
displayed on stdout.
-w seconds
Defines the number of seconds to wait before repeating command line options. This
option has no effect unless option -l is also specified with a non-zero value.
-?, --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.
ARGUMENTS
device The MAC address of some powerline device. More than one address may be specified.
If more than one address is specified then operations are performed on each device
in turn. The default address is local. See DEVICES for information about symbolic
device addresses.
LINKID
0x00,CSMA-CAP0
Display CSMA statistics for CAP0 traffic using a single peer node. The peer node
MAC address must be specified using option -p.
0x01,CSMA-CAP1
Display CSMA statistics for CAP1 traffic using a single peer node. The peer node
MAC address must be specified using option -p.
0x02,CSMA-CAP2
Display CSMA statistics for CAP2 traffic using a single peer node. The peer node
MAC address must be specified using option -p.
0x03,CSMA-CAP3
Display CSMA statistics for CAP3 traffic using a single peer node. The peer node
MAC address must be specified using option -p.
0xF8,CSMA-PEER
Display CSMA statistics for all traffic using a single peer node. The peer node
MAC address must be specified using option -p.
0xFC,CSMA-ALL
Display CSMA statistics for all traffic with all peer nodes. A peer node MAC
address is not needed and will be ignored if provided. This value is the default
for option -s.
DEVICES
Powerline devices use Ethernet Media Access Control (MAC) addresses. A MAC address is a
48-bit value entered as 12 hexadecimal digits in upper, lower or mixed character case.
Octets may be separated with colons for clarity. For example, "00b052000001",
"00:b0:52:00:00:01" and "00b052:000001" are valid and equivalent.
The following MAC addresses are special and may be entered by name instead of number.
all Same as "broadcast".
broadcast
A synonym for the Ethernet broadcast address, FF:FF:FF:FF:FF:FF. All devices,
whether local, remote or foreign recognize messages sent to this address. A remote
device is any device at the far end of a powerline connection. A foreign device is
any device not manufactured by Atheros.
local A synonym for the Qualcomm Atheros vendor specific Local Management Address (LMA),
00:B0:52:00:00:01. All local Atheros devices recognize this address but remote and
foreign devices do 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.
