plcmdio32 - Qualcomm Atheros 32-bit MDIO Register Editor
plcmdio32 [options] [device] [device]
[...]
Read or write global MDIO registers using multiple VS_MDIO_COMMAND
vendor-specific management messages. Commands are entered using 32-bit
register and data values then converted to threeequivalen 16-bit commands.
The default operation is to read a register. Registers are written only if
data is specified on the command line. Thsi program replaces program
int6kmdio2.
This program writes MDIO instructions using 802.3ae Clause
45 (address, data and mask) format. See program
int6kmdio for a similar program to write instructions using 802.3
Clause 22 (phy, reg, data and mask)
format.
This program is part of the Qualcomm Atheros Powerline Toolkit. It
replaces legacy program int6kmdio2. See the plc man page for
an overview and installation instructions.
- -a address
- The 19-bit global register address. Some devices may not support all
possible addresses. Addresses may be expressed in decimal, hexadecimal or
binary notation. Hexadecimal values must be prefixed with "0x"
or "0X". Binary values must be prefixed with "0b" or
"0B".
- -d data
- A 32-bit data value to be inserted into the specified register. The
specified data value is written when this option is present; otherwise the
specified register is read and the content is displayed. Data values may
be expressed in decimal, hexadecimal or binary notation. Hexadecimal
values are prefixed with "0x" or "0X". Binary values
are prefixed with "0b" or "0B".
- -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.
- -h
- When writing 32-bit values, write to the high-order register before the
low-order register. This option is needed in cases where the value in one
register may affect the interpretation of some value written to the other
register. This is not a common situation.
- -i interface
- 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.
- -q
- Suppresses status messages on stderr.
- -v
- Prints additional information on stdout. In particular, this option dumps
outgoing Ethernet packets on stdout.
- -?,--help
- Displays program help information on stderr. This option takes precedence
over all other options on the command line except version information.
- -!,--version
- Displays program version information on stderr. This option takes
precedence over all other options on the command line except help
information. Use this option when sending screen dumps to Atheros
technical staff.
- 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.
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.
