|

|

There are a few network parameters that can be tuned to better match
|
||||
the kernel to your system hardware and intended usage. The defaults
|
||||
are usually a good choice for 99% of the people 99% of the time, but
|
||||
you should be aware they do exist and can be changed.
|
||||
|
||||
The current list of parameters can be found in the files:
|
||||
|
||||
linux/net/TUNABLE
|
||||
Documentation/networking/ip-sysctl.txt
|
||||
|
||||
Some of these are accessible via the sysctl interface, and many more are
|
||||
scheduled to be added in this way. For example, some parameters related
|
||||
to Address Resolution Protocol (ARP) are very easily viewed and altered.
|
||||
|
||||
# cat /proc/sys/net/ipv4/arp_timeout
|
||||
6000
|
||||
# echo 7000 > /proc/sys/net/ipv4/arp_timeout
|
||||
# cat /proc/sys/net/ipv4/arp_timeout
|
||||
7000
|
||||
|
||||
Others are already accessible via the related user space programs.
|
||||
For example, MAX_WINDOW has a default of 32 k which is a good choice for
|
||||
modern hardware, but if you have a slow (8 bit) Ethernet card and/or a slow
|
||||
machine, then this will be far too big for the card to keep up with fast
|
||||
machines transmitting on the same net, resulting in overruns and receive errors.
|
||||
A value of about 4 k would be more appropriate, which can be set via:
|
||||
|
||||
# route add -net 192.168.3.0 window 4096
|
||||
|
||||
The remainder of these can only be presently changed by altering a #define
|
||||
in the related header file. This means an edit and recompile cycle.

INTRODUCTION
|
||||
|
||||
This document describes the software drivers and their use for the
|
||||
COMX line of synchronous serial adapters for Linux version 2.2.0 and
|
||||
above.
|
||||
The cards are produced and sold by ITC-Pro Ltd. Budapest, Hungary
|
||||
For further info contact <info@itc.hu>
|
||||
or http://www.itc.hu (mostly in Hungarian).
|
||||
The firmware files and software are available from ftp://ftp.itc.hu
|
||||
|
||||
Currently, the drivers support the following cards and protocols:
|
||||
|
||||
COMX (2x64 kbps intelligent board)
|
||||
CMX (1x256 + 1x128 kbps intelligent board)
|
||||
HiCOMX (2x2Mbps intelligent board)
|
||||
LoCOMX (1x512 kbps passive board)
|
||||
MixCOM (1x512 or 2x512kbps passive board with a hardware watchdog an
|
||||
optional BRI interface and optional flashROM (1-32M))
|
||||
SliceCOM (1x2Mbps channelized E1 board)
|
||||
PciCOM (X21)
|
||||
|
||||
At the moment of writing this document, the (Cisco)-HDLC, LAPB, SyncPPP and
|
||||
Frame Relay (DTE, rfc1294 IP encapsulation with partially implemented Q933a
|
||||
LMI) protocols are available as link-level protocol.
|
||||
X.25 support is being worked on.
|
||||
|
||||
USAGE
|
||||
|
||||
Load the comx.o module and the hardware-specific and protocol-specific
|
||||
modules you'll need into the running kernel using the insmod utility.
|
||||
This creates the /proc/comx directory.
|
||||
See the example scripts in the 'etc' directory.
|
||||
|
||||
/proc INTERFACE INTRO
|
||||
|
||||
The COMX driver set has a new type of user interface based on the /proc
|
||||
filesystem which eliminates the need for external user-land software doing
|
||||
IOCTL calls.
|
||||
Each network interface or device (i.e. those ones you configure with 'ifconfig'
|
||||
and 'route' etc.) has a corresponding directory under /proc/comx. You can
|
||||
dynamically create a new interface by saying 'mkdir /proc/comx/comx0' (or you
|
||||
can name it whatever you want up to 8 characters long, comx[n] is just a
|
||||
convention).
|
||||
Generally the files contained in these directories are text files, which can
|
||||
be viewed by 'cat filename' and you can write a string to such a file by
|
||||
saying 'echo _string_ >filename'. This is very similar to the sysctl interface.
|
||||
Don't use a text editor to edit these files, always use 'echo' (or 'cat'
|
||||
where appropriate).
|
||||
When you've created the comx[n] directory, two files are created automagically
|
||||
in it: 'boardtype' and 'protocol'. You have to fill in these files correctly
|
||||
for your board and protocol you intend to use (see the board and protocol
|
||||
descriptions in this file below or the example scripts in the 'etc' directory).
|
||||
After filling in these files, other files will appear in the directory for
|
||||
setting the various hardware- and protocol-related informations (for example
|
||||
irq and io addresses, keepalive values etc.) These files are set to default
|
||||
values upon creation, so you don't necessarily have to change all of them.
|
||||
|
||||
When you're ready with filling in the files in the comx[n] directory, you can
|
||||
configure the corresponding network interface with the standard network
|
||||
configuration utilities. If you're unable to bring the interfaces up, look up
|
||||
the various kernel log files on your system, and consult the messages for
|
||||
a probable reason.
|
||||
|
||||
EXAMPLE
|
||||
|
||||
To create the interface 'comx0' which is the first channel of a COMX card:
|
||||
|
||||
insmod comx
|
||||
# insmod comx-hw-comx ; insmod comx-proto-ppp (these are usually
|
||||
autoloaded if you use the kernel module loader)
|
||||
|
||||
mkdir /proc/comx/comx0
|
||||
echo comx >/proc/comx/comx0/boardtype
|
||||
echo 0x360 >/proc/comx/comx0/io <- jumper-selectable I/O port
|
||||
echo 0x0a >/proc/comx/comx0/irq <- jumper-selectable IRQ line
|
||||
echo 0xd000 >/proc/comx/comx0/memaddr <- software-configurable memory
|
||||
address. COMX uses 64 KB, and this
|
||||
can be: 0xa000, 0xb000, 0xc000,
|
||||
0xd000, 0xe000. Avoid conflicts
|
||||
with other hardware.
|
||||
cat </etc/siol1.rom >/proc/comx/comx0/firmware <- the firmware for the card
|
||||
echo HDLC >/proc/comx/comx0/protocol <- the data-link protocol
|
||||
echo 10 >/proc/comx/comx0/keepalive <- the keepalive for the protocol
|
||||
ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255 <-
|
||||
finally configure it with ifconfig
|
||||
Check its status:
|
||||
cat /proc/comx/comx0/status
|
||||
|
||||
If you want to use the second channel of this board:
|
||||
|
||||
mkdir /proc/comx/comx1
|
||||
echo comx >/proc/comx/comx1/boardtype
|
||||
echo 0x360 >/proc/comx/comx1/io
|
||||
echo 10 >/proc/comx/comx1/irq
|
||||
echo 0xd000 >/proc/comx/comx1/memaddr
|
||||
echo 1 >/proc/comx/comx1/channel <- channels are numbered
|
||||
as 0 (default) and 1
|
||||
|
||||
Now, check if the driver recognized that you're going to use the other
|
||||
channel of the same adapter:
|
||||
|
||||
cat /proc/comx/comx0/twin
|
||||
comx1
|
||||
cat /proc/comx/comx1/twin
|
||||
comx0
|
||||
|
||||
You don't have to load the firmware twice, if you use both channels of
|
||||
an adapter, just write it into the channel 0's /proc firmware file.
|
||||
|
||||
Default values: io 0x360 for COMX, 0x320 (HICOMX), irq 10, memaddr 0xd0000
|
||||
|
||||
THE LOCOMX HARDWARE DRIVER
|
||||
|
||||
The LoCOMX driver doesn't require firmware, and it doesn't use memory either,
|
||||
but it uses DMA channels 1 and 3. You can set the clock rate (if enabled by
|
||||
jumpers on the board) by writing the kbps value into the file named 'clock'.
|
||||
Set it to 'external' (it is the default) if you have external clock source.
|
||||
|
||||
(Note: currently the LoCOMX driver does not support the internal clock)
|
||||
|
||||
THE COMX, CMX AND HICOMX DRIVERS
|
||||
|
||||
On the HICOMX, COMX and CMX, you have to load the firmware (it is different for
|
||||
the three cards!). All these adapters can share the same memory
|
||||
address (we usually use 0xd0000). On the CMX you can set the internal
|
||||
clock rate (if enabled by jumpers on the small adapter boards) by writing
|
||||
the kbps value into the 'clock' file. You have to do this before initializing
|
||||
the card. If you use both HICOMX and CMX/COMX cards, initialize the HICOMX
|
||||
first. The I/O address of the HICOMX board is not configurable by any
|
||||
method available to the user: it is hardwired to 0x320, and if you have to
|
||||
change it, consult ITC-Pro Ltd.
|
||||
|
||||
THE MIXCOM DRIVER
|
||||
|
||||
The MixCOM board doesn't require firmware, the driver communicates with
|
||||
it through I/O ports. You can have three of these cards in one machine.
|
||||
|
||||
THE SLICECOM DRIVER
|
||||
|
||||
The SliceCOM board doesn't require firmware. You can have 4 of these cards
|
||||
in one machine. The driver doesn't (yet) support shared interrupts, so
|
||||
you will need a separate IRQ line for every board.
|
||||
Read Documentation/networking/slicecom.txt for help on configuring
|
||||
this adapter.
|
||||
|
||||
THE HDLC/PPP LINE PROTOCOL DRIVER
|
||||
|
||||
The HDLC/SyncPPP line protocol driver uses the kernel's built-in syncppp
|
||||
driver (syncppp.o). You don't have to manually select syncppp.o when building
|
||||
the kernel, the dependencies compile it in automatically.
|
||||
|
||||
|
||||
|
||||
|
||||
EXAMPLE
|
||||
(setting up hw parameters, see above)
|
||||
|
||||
# using HDLC:
|
||||
echo hdlc >/proc/comx/comx0/protocol
|
||||
echo 10 >/proc/comx/comx0/keepalive <- not necessary, 10 is the default
|
||||
ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255
|
||||
|
||||
(setting up hw parameters, see above)
|
||||
|
||||
# using PPP:
|
||||
echo ppp >/proc/comx/comx0/protocol
|
||||
ifconfig comx0 up
|
||||
ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255
|
||||
|
||||
|
||||
THE LAPB LINE PROTOCOL DRIVER
|
||||
|
||||
For this, you'll need to configure LAPB support (See 'LAPB Data Link Driver' in
|
||||
'Network options' section) into your kernel (thanks to Jonathan Naylor for his
|
||||
excellent implementation).
|
||||
comx-proto-lapb.o provides the following files in the appropriate directory
|
||||
(the default values in parens): t1 (5), t2 (1), n2 (20), mode (DTE, STD) and
|
||||
window (7). Agree with the administrator of your peer router on these
|
||||
settings (most people use defaults, but you have to know if you are DTE or
|
||||
DCE).
|
||||
|
||||
EXAMPLE
|
||||
|
||||
(setting up hw parameters, see above)
|
||||
echo lapb >/proc/comx/comx0/protocol
|
||||
echo dce >/proc/comx/comx0/mode <- DCE interface in this example
|
||||
ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255
|
||||
|
||||
|
||||
THE FRAME RELAY PROTOCOL DRIVER
|
||||
|
||||
You DON'T need any other frame relay related modules from the kernel to use
|
||||
COMX-Frame Relay. This protocol is a bit more complicated than the others,
|
||||
because it allows to use 'subinterfaces' or DLCIs within one physical device.
|
||||
First you have to create the 'master' device (the actual physical interface)
|
||||
as you would do for other protocols. Specify 'frad' as protocol type.
|
||||
Now you can bring this interface up by saying 'ifconfig comx0 up' (or whatever
|
||||
you've named the interface). Do not assign any IP address to this interface
|
||||
and do not set any routes through it.
|
||||
Then, set up your DLCIs the following way: create a comx interface for each
|
||||
DLCI you intend to use (with mkdir), and write 'dlci' to the 'boardtype' file,
|
||||
and 'ietf-ip' to the 'protocol' file. Currently, the only supported
|
||||
encapsulation type is this (also called as RFC1294/1490 IP encapsulation).
|
||||
Write the DLCI number to the 'dlci' file, and write the name of the physical
|
||||
COMX device to the file called 'master'.
|
||||
Now you can assign an IP address to this interface and set routes using it.
|
||||
See the example file for further info and example config script.
|
||||
Notes: this driver implements a DTE interface with partially implemented
|
||||
Q933a LMI.
|
||||
You can find an extensively commented example in the 'etc' directory.
|
||||
|
||||
FURTHER /proc FILES
|
||||
|
||||
boardtype:
|
||||
Type of the hardware. Valid values are:
|
||||
'comx', 'hicomx', 'locomx', 'cmx', 'slicecom'.
|
||||
|
||||
protocol:
|
||||
Data-link protocol on this channel. Can be: HDLC, LAPB, PPP, FRAD
|
||||
|
||||
status:
|
||||
You can read the channel's actual status from the 'status' file, for example
|
||||
'cat /proc/comx/comx3/status'.
|
||||
|
||||
lineup_delay:
|
||||
Interpreted in seconds (default is 1). Used to avoid line jitter: the system
|
||||
will consider the line status 'UP' only if it is up for at least this number
|
||||
of seconds.
|
||||
|
||||
debug:
|
||||
You can set various debug options through this file. Valid options are:
|
||||
'comx_events', 'comx_tx', 'comx_rx', 'hw_events', 'hw_tx', 'hw_rx'.
|
||||
You can enable a debug options by writing its name prepended by a '+' into
|
||||
the debug file, for example 'echo +comx_rx >comx0/debug'.
|
||||
Disabling an option happens similarly, use the '-' prefix
|
||||
(e.g. 'echo -hw_rx >debug').
|
||||
Debug results can be read from the debug file, for example:
|
||||
tail -f /proc/comx/comx2/debug

This is the README for the Gracilis Packetwin device driver, version 0.5
|
||||
ALPHA for Linux 1.3.43.
|
||||
|
||||
These files will allow you to talk to the PackeTwin (now know as PT) and
|
||||
connect through it just like a pair of TNCs. To do this you will also
|
||||
require the AX.25 code in the kernel enabled.
|
||||
|
||||
There are four files in this archive; this readme, a patch file, a .c file
|
||||
and finally a .h file. The two program files need to be put into the
|
||||
drivers/net directory in the Linux source tree, for me this is the
|
||||
directory /usr/src/linux/drivers/net. The patch file needs to be patched in
|
||||
at the top of the Linux source tree (/usr/src/linux in my case).
|
||||
|
||||
You will most probably have to edit the pt.c file to suit your own setup,
|
||||
this should just involve changing some of the defines at the top of the file.
|
||||
Please note that if you run an external modem you must specify a speed of 0.
|
||||
|
||||
The program is currently setup to run a 4800 baud external modem on port A
|
||||
and a Kantronics DE-9600 daughter board on port B so if you have this (or
|
||||
something similar) then you're right.
|
||||
|
||||
To compile in the driver, put the files in the correct place and patch in
|
||||
the diff. You will have to re-configure the kernel again before you
|
||||
recompile it.
|
||||
|
||||
The driver is not real good at the moment for finding the card. You can
|
||||
'help' it by changing the order of the potential addresses in the structure
|
||||
found in the pt_init() function so the address of where the card is is put
|
||||
first.
|
||||
|
||||
After compiling, you have to get them going, they are pretty well like any
|
||||
other net device and just need ifconfig to get them going.

||||

previous (non-GPL) versions of the driver, please update to this one.
|

I hope that this all works well for you. I would be pleased to hear how
|

many people use the driver and if it does its job.

interfeszekhez. WAN halozatokban ennel hosszabbat is szokas hasznalni

(20 es 100 kozott), hogy a vonal kihasznaltsaga nagy terheles eseten jobb

legyen (bar ezzel megno a varhato kesleltetes a csomagok sorban allasa miatt):

Az altalanos,- es a protokoll-retegek beallitasi lehetosegeirol a 'comx.txt'
|
||||
fajlban leirtak SliceCOM kartyanal is ervenyesek, itt csak a hardver-specifikus
|
||||
beallitasi lehetosegek vannak osszefoglalva:
|
||||
|
||||
Konfiguralasi interfesz a /proc/comx/ alatt:
|
||||
|
||||
Minden timeslot-csoportnak kulon comx* interfeszt kell letrehozni mkdir-rel:
|
||||
comx0, comx1, .. stb. Itt beallithato, hogy az adott interfesz hanyadik kartya
|
||||
melyik timeslotja(i)bol alljon ossze. A Cisco-fele serial3:1 elnevezesek
|
||||
(serial3:1 = a 3. kartyaban az 1-es idoszelet-csoport) Linuxon aliasing-ot
|
||||
jelentenenek, ezert mi nem tudunk ilyen elnevezest hasznalni.
|
||||
|
||||
Tobb kartya eseten a comx0.1, comx0.2, ... vagy slice0.1, slice0.2 nevek
|
||||
hasznalhatoak.
|
||||
|
||||
Tobb SliceCOM kartya is lehet egy gepben, de sajat interrupt kell mindegyiknek,
|
||||
nem tud meg megosztott interruptot kezelni.
|
||||
|
||||
Az egesz kartyat erinto beallitasok:
|
||||
|
||||
Az ioport es irq beallitas nincs: amit a PCI BIOS kioszt a rendszernek,
|
||||
azt hasznalja a driver.
|
||||
|
||||
|
||||
comx0/boardnum - hanyadik SliceCOM kartya a gepben (a 'termeszetes' PCI
|
||||
sorrendben ertve: ahogyan a /proc/pci-ban vagy az 'lspci'
|
||||
kimeneteben megjelenik, altalaban az alaplapi PCI meghajto
|
||||
aramkorokhoz kozelebb eso kartyak a kisebb sorszamuak)
|
||||
|
||||
Default: 0 (0-tol kezdodik a szamolas)
|
||||
|
||||
|
||||
Bar a kovetkezoket csak egy-egy interfeszen allitjuk at, megis az egesz kartya
|
||||
mukodeset egyszerre allitjak. A megkotes hogy csak UP-ban levo interfeszen
|
||||
hasznalhatoak, azert van, mert kulonben nem vart eredmenyekre vezetne egy ilyen
|
||||
paranccsorozat:
|
||||
|
||||
echo 0 >boardnum
|
||||
echo internal >clock_source
|
||||
echo 1 >boardnum
|
||||
|
||||
- Ez a 0-s board clock_source-at allitana at.
|
||||
|
||||
Ezek a beallitasok megmaradnak az osszes interfesz torlesekor, de torlodnek
|
||||
a driver modul ki/betoltesekor.
|
||||
|
||||
|
||||
comx0/clock_source - A Tx orajelforrasa, a Cisco-val hasonlatosra keszult.
|
||||
Hasznalata:
|
||||
|
||||
papaya:# echo line >/proc/comx/comx0/clock_source
|
||||
papaya:# echo internal >/proc/comx/comx0/clock_source
|
||||
|
||||
line - A Tx orajelet a vett adatfolyambol dekodolja, igyekszik
|
||||
igazodni hozza. Ha nem lat orajelet az inputon, akkor
|
||||
atall a sajat orajelgeneratorara.
|
||||
internal - A Tx orajelet a sajat orajelgeneratora szolgaltatja.
|
||||
|
||||
Default: line
|
||||
|
||||
Normal osszeallitas eseten a tavkozlesi szolgaltato eszkoze
|
||||
(pl. HDSL modem) adja az orajelet, ezert ez a default.
|
||||
|
||||
|
||||
comx0/framing - A CRC4 ki/be kapcsolasa
|
||||
|
||||
A CRC4: 16 PCM keretet (A PCM keret az, amibe a 32 darab 64
|
||||
kilobites csatorna van bemultiplexalva. Nem osszetevesztendo a HDLC
|
||||
kerettel.) 2x8 -as csoportokra osztanak, es azokhoz 4-4 bites CRC-t
|
||||
szamolnak. Elsosorban a vonal minosegenek a monitorozasara szolgal.
|
||||
|
||||
papaya:~# echo crc4 >/proc/comx/comx0/framing
|
||||
papaya:~# echo no-crc4 >/proc/comx/comx0/framing
|
||||
|
||||
Default a 'crc4', a MATAV vonalak altalaban igy futnak. De ha nem
|
||||
egyforma is a beallitas a vonal ket vegen, attol a forgalom altalaban
|
||||
at tud menni.
|
||||
|
||||
|
||||
comx0/linecode - A vonali kodolas beallitasa
|
||||
|
||||
papaya:~# echo hdb3 >/proc/comx/comx0/linecode
|
||||
papaya:~# echo ami >/proc/comx/comx0/linecode
|
||||
|
||||
Default a 'hdb3', a MATAV vonalak igy futnak.
|
||||
|
||||
(az AMI kodolas igen ritka E1-es vonalaknal). Ha ez a beallitas nem
|
||||
egyezik a vonal ket vegen, akkor elofordulhat hogy a keretszinkron
|
||||
osszejon, de CRC4-hibak es a vonalakon atvitt adatokban is hibak
|
||||
keletkeznek (amit a HDLC/SyncPPP szinten CRC-hibaval jelez)
|
||||
|
||||
|
||||
comx0/reg - a kartya aramkoreinek, a MUNICH (reg) es a FALC (lbireg)
|
||||
comx0/lbireg regisztereinek kozvetlen elerese. Hasznalata:
|
||||
|
||||
echo >reg 0x04 0x0 - a 4-es regiszterbe 0-t ir
|
||||
echo >reg 0x104 - printk()-val kiirja a 4-es regiszter
|
||||
tartalmat a syslogba.
|
||||
|
||||
WARNING: ezek csak a fejleszteshez keszultek, sok galibat
|
||||
lehet veluk okozni!
|
||||
|
||||
|
||||
comx0/loopback - A kartya G.703 jelenek a visszahurkolasara is van lehetoseg:
|
||||
|
||||
papaya:# echo none >/proc/comx/comx0/loopback
|
||||
papaya:# echo local >/proc/comx/comx0/loopback
|
||||
papaya:# echo remote >/proc/comx/comx0/loopback
|
||||
|
||||
none - nincs visszahurkolas, normal mukodes
|
||||
local - a kartya a sajat maga altal adott jelet kapja vissza
|
||||
remote - a kartya a kivulrol vett jelet adja kifele
|
||||
|
||||
Default: none
|
||||
|
||||
-----------------------------------------------------------------
|
||||
|
||||
Az interfeszhez (Cisco terminologiaban 'channel-group') kapcsolodo beallitasok:
|
||||
|
||||
comx0/timeslots - mely timeslotok (idoszeletek) tartoznak az adott interfeszhez.
|
||||
|
||||
papaya:~# cat /proc/comx/comx0/timeslots
|
||||
1 3 4 5 6
|
||||
papaya:~#
|
||||
|
||||
Egy timeslot megkeresese (hanyas interfeszbe tartozik nalunk):
|
||||
|
||||
papaya:~# grep ' 4' /proc/comx/comx*/timeslots
|

/proc/comx/comx0/timeslots:1 3 4 5 6
|

papaya:~#
|
||||
|
||||
Beallitasa:
|
||||
papaya:~# echo '1 5 2 6 7 8' >/proc/comx/comx0/timeslots
|
||||
|
||||
A timeslotok sorrendje nem szamit, '1 3 2' ugyanaz mint az '1 2 3'.
|
||||
|
||||
Beallitashoz az adott interfesznek DOWN-ban kell lennie
|
||||
(ifconfig comx0 down), de ugyanannak a kartyanak a tobbi interfesze
|
||||
uzemelhet kozben.
|
||||
|
||||
Beallitaskor leellenorzi, hogy az uj timeslotok nem utkoznek-e egy
|
||||
masik interfesz timeslotjaival. Ha utkoznek, akkor nem allitja at.
|
||||
|
||||
Mindig 10-es szamrendszerben tortenik a timeslotok ertelmezese, nehogy
|
||||
a 08, 09 alaku felirast rosszul ertelmezze.

modprobe comx-proto-ppp # module for Cisco-HDLC and SyncPPP protocols
|
||||
|

modprobe comx-hw-munich # the module logs information by the kernel
|
||||
# about the detected boards
|
||||
|
||||
|
||||
Configuring the board:
|
||||
|
||||
# This interface will use the Cisco-HDLC line protocol,
|
||||
# the timeslices assigned are 1,2 (128 KiBit line speed)
|
||||

||||
|

# This interface uses SyncPPP line protocol, the assigned
|
||||
# is no. 3 (64 KiBit line speed)
|
||||
#
|
||||
mkdir /proc/comx/comx0.2/
|
||||
echo slicecom >/proc/comx/comx0.2/boardtype
|
||||
echo ppp >/proc/comx/comx0.2/protocol
|
||||
echo 3 >/proc/comx/comx0.2/timeslots
|
||||
|
||||
...
|
||||
|
||||
ifconfig comx0.1 up
|
||||
ifconfig comx0.2 up
|
||||
|
||||
-----------------------------------------------------------------
|
||||
|
||||
The COMX interfaces use a 10 packet transmit queue by default, however WAN
|
||||
networks sometimes use bigger values (20 to 100), to utilize the line better
|
||||
by large traffic (though the line delay increases because of more packets
|
||||
join the queue).
|
||||
|
||||
# ifconfig comx0 txqueuelen 50
|
||||
|
||||
This option is only supported by the ifconfig command of the later
|
||||
distributions, which came with 2.2 kernels, such as RedHat 6.1 or Debian 2.2.
|
||||
|
||||
You can download a newer netbase packet from
|
||||
http://www.debian.org/~rcw/2.2/netbase/ for Debian 2.1, which has a new
|
||||
ifconfig. You can get further information about using 2.2 kernel with
|
||||
Debian 2.1 from http://www.debian.org/releases/stable/running-kernel-2.2
|
||||
|
||||
-----------------------------------------------------------------
|
||||
|
||||
The SliceCom LEDs:
|
||||
|
||||
red - on, if the interface is unconfigured, or it gets Remote Alarm-s
|
||||
green - on, if the board finds frame-sync in the received signal
|
||||
|
||||
A bit more detailed:
|
||||
|
||||
red: green: meaning:
|
||||
|
||||
- - no frame-sync, no signal received, or signal SNAFU.
|
||||
- on "Everything is OK"
|
||||
on on Reception is ok, but the remote end sends Remote Alarm
|
||||
on - The interface is unconfigured
|
||||
|
||||
-----------------------------------------------------------------
|
||||
|
||||
A more detailed description of the hardware setting options:
|
||||
|
||||
The general and the protocol layer options described in the 'comx.txt' file
|
||||
apply to the SliceCom as well, I only summarize the SliceCom hardware specific
|
||||
settings below.
|
||||
|
||||
The '/proc/comx' configuring interface:
|
||||
|
||||
An interface directory should be created for every timeslot group with
|
||||
'mkdir', e,g: 'comx0', 'comx1' etc. The timeslots can be assigned here to the
|
||||
specific interface. The Cisco-like naming convention (serial3:1 - first
|
||||
timeslot group of the 3rd. board) can't be used here, because these mean IP
|
||||
aliasing in Linux.
|
||||
|
||||
You can give any meaningful name to keep the configuration clear;
|
||||
e.g: 'comx0.1', 'comx0.2', 'comx1.1', comx1.2', if you have two boards
|
||||
with two interfaces each.
|
||||
|
||||
Settings, which apply to the board:
|
||||
|
||||
Neither 'io' nor 'irq' settings required, the driver uses the resources
|
||||
given by the PCI BIOS.
|
||||
|
||||
comx0/boardnum - board number of the SliceCom in the PC (using the 'natural'
|
||||
PCI order) as listed in '/proc/pci' or the output of the
|
||||
'lspci' command, generally the slots nearer to the motherboard
|
||||
PCI driver chips have the lower numbers.
|
||||
|
||||
Default: 0 (the counting starts with 0)
|
||||
|
||||
Though the options below are to be set on a single interface, they apply to the
|
||||
whole board. The restriction, to use them on 'UP' interfaces, is because the
|
||||
command sequence below could lead to unpredictable results.
|
||||
|
||||
# echo 0 >boardnum
|
||||
# echo internal >clock_source
|
||||
# echo 1 >boardnum
|
||||
|
||||
The sequence would set the clock source of board 0.
|
||||
|
||||
These settings will persist after all the interfaces are cleared, but are
|
||||
cleared when the driver module is unloaded and loaded again.
|
||||
|
||||
comx0/clock_source - source of the transmit clock
|
||||
Usage:
|
||||
|
||||
# echo line >/proc/comx/comx0/clock_source
|
||||
# echo internal >/proc/comx/comx0/clock_source
|
||||
|
||||
line - The Tx clock is being decoded if the input data stream,
|
||||
if no clock seen on the input, then the board will use it's
|
||||
own clock generator.
|
||||
|
||||
internal - The Tx clock is supplied by the builtin clock generator.
|
||||
|
||||
Default: line
|
||||
|
||||
Normally, the telecommunication company's end device (the HDSL
|
||||
modem) provides the Tx clock, that's why 'line' is the default.
|
||||
|
||||
comx0/framing - Switching CRC4 off/on
|
||||
|
||||
CRC4: 16 PCM frames (The 32 64Kibit channels are multiplexed into a
|
||||
PCM frame, nothing to do with HDLC frames) are divided into 2x8
|
||||
groups, each group has a 4 bit CRC.
|
||||
|
||||
# echo crc4 >/proc/comx/comx0/framing
|
||||
# echo no-crc4 >/proc/comx/comx0/framing
|
||||
|
||||
Default is 'crc4', the Hungarian MATAV lines behave like this.
|
||||
The traffic generally passes if this setting on both ends don't match.
|
||||
|
||||
comx0/linecode - Setting the line coding
|
||||
|
||||
# echo hdb3 >/proc/comx/comx0/linecode
|
||||
# echo ami >/proc/comx/comx0/linecode
|
||||
|
||||
Default a 'hdb3', MATAV lines use this.
|
||||
|
||||
(AMI coding is rarely used with E1 lines). Frame sync may occur, if
|
||||
this setting doesn't match the other end's, but CRC4 and data errors
|
||||
will come, which will result in CRC errors on HDLC/SyncPPP level.
|
||||
|
||||
comx0/reg - direct access to the board's MUNICH (reg) and FALC (lbireg)
|
||||
comx0/lbireg circuit's registers
|
||||
|
||||
# echo >reg 0x04 0x0 - write 0 to register 4
|
||||
# echo >reg 0x104 - write the contents of register 4 with
|
||||
printk() to syslog
|
||||
|
||||
WARNING! These are only for development purposes, messing with this will
|
||||
result much trouble!
|
||||
|
||||
comx0/loopback - Places a loop to the board's G.703 signals
|
||||
|
||||
# echo none >/proc/comx/comx0/loopback
|
||||
# echo local >/proc/comx/comx0/loopback
|
||||
# echo remote >/proc/comx/comx0/loopback
|
||||
|
||||
none - normal operation, no loop
|
||||
local - the board receives it's own output
|
||||
remote - the board sends the received data to the remote side
|
||||
|
||||
Default: none
|
||||
|
||||
-----------------------------------------------------------------
|
||||
|
||||
Interface (channel group in Cisco terms) settings:
|
||||
|
||||
comx0/timeslots - which timeslots belong to the given interface
|
||||
|
||||
Setting:
|
||||
|
||||
# echo '1 5 2 6 7 8' >/proc/comx/comx0/timeslots
|
||||
|
||||
# cat /proc/comx/comx0/timeslots
|
||||
1 2 5 6 7 8
|
||||
#
|
||||
|
||||
Finding a timeslot:
|
||||
|
||||
# grep ' 4' /proc/comx/comx*/timeslots
|
||||
/proc/comx/comx0/timeslots:1 3 4 5 6
|
||||
#
|
||||
|
||||
The timeslots can be in any order, '1 2 3' is the same as '1 3 2'.
|
||||
|
||||
The interface has to be DOWN during the setting ('ifconfig comx0
|
||||
down'), but the other interfaces could operate normally.
|
||||
|
||||
The driver checks if the assigned timeslots are vacant, if not, then
|
||||
the setting won't be applied.
|
||||
|
||||
The timeslot values are treated as decimal numbers, not to misunderstand
|
||||
values of 08, 09 form.
|
||||
|
||||
-----------------------------------------------------------------
|
||||
|
||||

|
||||

||||

|
||||
which begin with '//' are the comments.
