Configuring the TLX ASCII Interface

Accessing the ASCII Interface

The ASCII Interface is accessible via the serial RS-232 port located on the TLX Matrix Switch’s

Controller Card or over the network via a TCP connection. Both connections use the same

syntax. The command syntax is defined in the document: Matrix_Switch_ASCII_API.

The serial port is configured for 9600 baud, 1 stop bit, no parity, and software flow control.

Each line contains only one command and must end with a carriage return (CR) and line feed (LF), or

just a line feed (LF). The characters are not echoed.

The network interface listens on TCP port 17567. It accepts the same commands as the serial

interface. You may use telnet to manually open a connection to control the Matrix Switch.

Configuring the TLX ASCII Interface thinklogical Rev. E – Jan. 2019

API Command Line Options

Each Matrix Switch model has its own API program. Examples are: tlx48api, tlx320api and

tlx640api. The generic name that is used in place of the actual name is: tlxapi.

The interface program has several options to control its operation. These options can be listed by

running the API program with the option '--help'. See the example below:

Version: V5.07.07 (build: 8)

Usage: tlx320api [options]

minimum is 500, maximum is 15000, 0 will disable the broadcast

if multicast is enabled, it will use this time setting

--bcast=0 will disable: broadcasts, multicasts, and the 'restore

connections' feature to disable network broadcasts but keep the 'restore'

feature, use the --noexternalbcast option

--idle[=]seconds network connections idle for at least these many seconds are candidates

to be forcibly closed when a new connection is made and there are no

available sockets.

Setting it to 0 will disable this feature. The default setting is 60

seconds.

Changing the Command Line Options

The command line options are stored in the file: /etc/default/tlxapi.

The default file contents are:

# Defaults for tlxapi initscript

# sourced by /etc/init.d/tlxapi

# installed at /etc/default/tlxapi by the maintainer scripts

# This is a POSIX shell fragment

## set this to 'no' and the daemon will not run

APIRUN=yes

## some API command line options you might need to use...

## ---- network options ----

## -N|--connections[=]n set the maximum number of open connections allowed (default:

1024)

## --noexternalapi only listen on 'localhost' for API connections

## ---- serial options ----

## --serial=none disables the API serial port /dev/ttymxc1

## -B|--baud[=]speed sets serial baud rate (default: 9600)

## ---- generic options ----

## --CR output CRLF instead of just LF (network connection only)

## --api write API messages received to the log file (level: NOTICE)

## --clog write connection status changes to the log file (level: NOTICE)

## --log_ip include the IP address with each API message that is logged (level:

NOTICE)

## --delay[=]delay in ms, how long an output must remain off, default is 300 ms.

## minimum is 50ms, maximum is 1000ms, 0 will disable the delay

## -b|--bcast[=]period in ms, how long between port status broadcasts, default is 4000 ms.

## minimum is 500, maximum is 15000, 0 will disable the broadcast

## if multicast is enabled, it will use this time setting

## --bcast=0 will disable BOTH broadcasts and multicasts

## --idle[=]seconds network connections idle for at least these many seconds are

candidates to be forcibly closed when a new connection is made and there are no available sockets.

## Setting it to 0 will disable this feature. The default setting is 60

seconds.

# Command line options that are passed to tlxapi.

TLXAPI_ARGS="--verbose --api"

Command line options are added to the TLXAPI_ARGS line.

For example, to change the serial port baud rate to 115200 and send a CRLF at the end of each line,

the TLXAPI_ARGS line will be: TLXAPI_ARGS="--verbose --api --baud=115200 --CR"

After the file is modified and saved, the following command will restart the API with the new settings:

service tlxapi restart

Note: Any changes you make to the switch firmware will be lost if you install a new SD

card from Thinklogical.

Configuring the TLX ASCII Interface thinklogical Rev. E – Jan. 2019

Debugging Aids

The API program has several options to aid in setup and debugging. These include logging the

incoming ASCII commands, logging the communications to the internal control process (aka AVR or

Control) and appending a comment to the response message that is returned after each command.

This comment will contain details about any errors.

These messages are written to the system log file: /var/log/api located on the Switch's internal

SD card.

Command line options to enable the API debug aids:

• --debug log extensive detailed data

• --api log the API commands received

• --avr log the commands to the internal control process

• --clog log connection make/break status

• --verbose append a comment to each command response

• --log_ip include the IP address with each API message that is logged

The '--api' and '--avr' settings may be toggled by sending a system signal to the running API program.

As shown in the help text on pg. 6 (near the bottom of the page), SIGUSR1 will toggle the 'api' setting

and SIGUSR2 will toggle the 'avr' setting. (See the example below for the syntax of the 'killall'

command.)

You may use the killall command to send a signal to a running program. The syntax is:

killall -USR1 tlxapi

killall -USR2 tlxapi

Configuring the TLX ASCII Interface thinklogical Rev. E – Jan. 2019

Using ‘PuTTY’ to Communicate to the API

Upon opening PuTTY (a Windows communication program) to communicate to a switch, you must

first set the following:

1. Under Category:, click on Session

2. Under Connection type:, select Raw mode

3. Change the port to 17567

4. Under Category:, click on Terminal

5. Under Options controlling the terminal emulation, check Implicit CR in every LF

6. Click Open.

You may also use telnet to access the ASCII control port. The command syntax is:

telnet IPaddress 17567

Replace IPaddress with the actual IP address of the switch.

Configuring the TLX ASCII Interface thinklogical Rev. E – Jan. 2019

Log File Debugging Entries

When debugging is turned on, several types of messages are written to the system log file:

/var/log/api.

For example, below are listed five commands that were sent to a TLX320 Matrix Switch. Below those

commands is a snippet of the log file showing the corresponding log entries. The first line in the log

file records the event that enabled logging.

Ci0150o0151

Si0150

So0151

Do0151

Ci0312o0001

imxs tlxapi[1851]: caught signal SIGUSR1 (10), turn on api debugging

imxs tlxapi[1851]: command: Ci0150o0151 response: R0000OK#Ci0150o0151

imxs tlxapi[1851]: command: Si0150 response: R0000OKI0150O0151#Si0150

imxs tlxapi[1851]: command: So0151 response: R0000OKI0150O0151#So0151

imxs tlxapi[1851]: command: Do0151 response: R0000OK#Do0151

imxs tlxapi[1851]: command: Ci0312o0001 response: R0000OK#Ci0312o0001

These log entries list the command that was received and the response that was sent back to the

sender.

The log files contain other system related messages and are a valuable aid in troubleshooting. Linux

offers the means to send these log file entries over the network to another system. Further

information may be found in the document: Matrix_Switch_Interfaces.

A Note to Telnet Users:

By default, tlxapi does not send a CR on each line. This is inherent in the Windows telnet client

software. The API, however, has a command to enable the sending of CR's. This command is

XCRON.

If your telnet output from tlxapi is displayed incorrectly on the screen, Thinklogical recommends using

the XCRON command.

Configuring the TLX ASCII Interface thinklogical Rev. E – Jan. 2019

Disabling ‘Broadcast’ on Switch Input Ports

The API may be configured so that input ports are restricted to one output port at a time. If

input X is first connected to output A, then connected to output B, X will be disconnected from A and

moved to B. This mode is referred to as Point-to-Point mode, or P2P for short.

The P2P definitions are stored on the Controller SD card in the following file:

/var/local/router/p2p/upstream.csv

P2P mode is disabled when the definition file does not exist. By default, when there is no file,

input ports may connect simultaneously to any number of output ports. All Matrix Switches are

shipped without a P2P file.

These files are in the form of a comma separated value (csv) file. Each entry in the file is the input

port to be restricted to P2P mode. There may be one or more entries per line in the file. The only

characters allowed in the file are the digits 0 thru 9, commas, and spaces. Blank lines are allowed.

An example that set ports 1, 2, 3, 4, 9, 11 and 15 to P2P mode is:

1,2,3,4

11, 15

As a shortcut, you may use the value 9999 to indicate ALL input ports.

If you make changes to either of these files, you can force the API to reread them by issuing the

command:

killall -HUP tlxapi

If P2P files are found at startup, the API will log this to the file: /var/log/api.

An example is shown below.

imxs tlxapi[9389]: parsing P2P csv file /var/local/router/p2p/upstream.csv

imxs tlxapi[9389]: parse_api_csv_file.c@133: line 1 of csv file /var/local/router/p2p/upstream.csv '1,2,3,4#012'

imxs tlxapi[9389]: point-to-point mode enabled

Configuring the TLX ASCII Interface thinklogical Rev. E – Jan. 2019

Using ‘Multicast’ to Send Switch Status Instead of ‘Broadcast’

The API has a command line option for using a network multicast address instead of a broadcast

address to deliver switch status messages. The default mode of the API will broadcast its status over

the network. The use of a multicast address allows these messages to be routed to other

network segments.

The command line option to enable multicast is --mcast. Without additional options, it will enable

multicast using the default IP address of 239.255.13.9. When multicasting is enabled, the API will

create a log entry showing the IP address it is using.

imxs tlxapi[9389]: Using multicast IP address 239.255.13.9

imxs tlxapi[9389]: multicast mode enabled

If broadcast is in effect, the log file will record that information.

imxs tlxapi[9389]: Using broadcast IP address 192.168.13.255

If you prefer to not use the default multicast address, you can specify the preferred address on the

command line by adding an equal sign ‘=’ and the IP address to the --mcast option. For example: --

mcast=239.255.13.105

____________________________________________________________________________

Warning! The selection of a multicast address is beyond the scope of this document, in

which case, you may need to contact your IT / Networking department. The address you

use may have some effect on your network infrastructure, so be sure to contact the

appropriate, qualified personnel.

____________________________________________________________________________

The API will attempt to use the specified multicast IP address. If it cannot connect to that address, the

API will fall back to using broadcast. This is also logged.

The example below shows an attempt to use the IP address of 1.2.3.4. The API was not able to

connect to that address, so it went back to using broadcast.

imxs tlxapi[9389]: broadcast_setup() vxASCIIapi.c@5193: Error: (Cannot assign requested address)

in bind [IP address = 1.2.3.4], switching to broadcast

imxs tlxapi[9389]: Using broadcast IP address 192.168.13.255

Both broadcast and multicast will use UDP port 17564 to transmit the status.

ASCII API (selected) Command Line Options

--connections=n

This option controls the maximum number of network connections allowed. Once the maximum is

reached, no more connections will be made until an existing connection is closed. The default

maximum is set at 128. The maximum may range from 9 to 2048.

Typically, connections are created, used and then closed. However, if the system connecting to the

API crashes, or is somehow physically disconnected from the Switch without closing the connection,

the API keeps this connection in place. This is a good thing if, for example, the network cable is

disconnected for a time and then reconnected. Both systems pick up where they left off. But, if while

the cable is disconnected, the other system crashes, restarts or is turned off, the API does not know

this and patiently waits for it to return.

This half-open connection will eventually time out, but this takes almost 2 hours to occur. This timeout

is a standard network feature called TCP_KEEPALIVE.

Configuring the TLX ASCII Interface thinklogical Rev. E – Jan. 2019

--idle=n

This option is used in conjunction with –connections and sets a minimum connection idle time. When

all available connections are used, the API looks for an existing connection that has been idle for at

least this minimum number of seconds. It will look for the connection that has been idle the longest

and terminate it. This makes a connection available for the latest request. If no connection has been

idle for the minimum time, then the new connection is refused.

The default idle time is set to 60 seconds. The maximum setting is 1800 seconds. Setting it to zero

will disable this feature and connections will stay in place until closed by the other side.

--noexternalapi

This option restricts network access to the API at the internal IP address of 127.0.0.1 (also known as

localhost). This option is typically used with the port redirection feature of SSH to create a secure,

encrypted tunnel between the API and the outside world. SSH port redirection is beyond the scope of

this document.

The Controller Card Serial Port is not affected by this option and may still be used, unless disabled

with the —serial=none command line option.

--noexternalbcast

Normally, the TLX Switch broadcasts status messages on (UDP) port 17564 on the network broad-

cast address of 192.168.13.255*. This option restricts the status broadcast to only 127.0.0.1

(localhost).

*This is the default network address. If the end user changes the network settings, this address may change.

--log_ip

Useful when debugging network connection errors, this option turns on some debugging messages

in the API log file (/var/log/api). It logs when connections are opened and closed, the number of

active connections and the IP address of the connection request. It also adds the IP address of the

system that sent a command to the command log file entry, as noted below ( ).
