Automated Debugging:
--------------------

The wanrouter operation script can retrieve the
most common line error statistics that can
give the user a good idea of what is going on
with the line.

	/usr/sbin/wanrouter debug if_name
or 
	/usr/sbin/wanrouter debug if_name > debug_file.txt

(where if_name is the name of wanpipe interface: eg: wp1fr16)


Sangoma Tech Support:
---------------------
   
   When reporting problems to Sangoma Tech Support please
   dump the current system debug information into
   a temporary file and send it via email.

   	1. wanrouter debug wp1fr16 > sangoma_debug_file.txt

	2. Wait for 2-5 minutes

	3. Stop the debug by pressing ENTER

	4. Email sangoma_debug_file.txt to Sangoma Tech Support



Wanpipe Debugger
----------------

At the heart of WANPIPE debugging is the 'wanpipemon'
debugging program.  It is used to display line
traces, protocol statistics, hardware statistics
and configuration parameters.


	/usr/sbin/wanpipemon -g


'wanpipemon' usage
==================

	/usr/sbin/wanpipemon

Wanpipemon Verison 1.0
Copyright (C) 2002 - Sangoma Technologies

Usage:  (Options in {} brackets are optional)

        #Command prompt Local debugging
        wanpipemon -i <interface> -c <command> { -p <protocol> }

        #Command prompt Remote debugging
        wanpipemon -i <remote IP> -u <port> -c <command> { -p <protocol> }

        #GUI interface
        wanpipemon -g { -i <interface|IP> -u <port> -p <protocol> }  

        #Display usage for each protocol
        wanpipemon -p [fr|ppp|chdlc|x25|adsl]

        #Detailed usage for each option
        wanpipemon -h


The 'wanpipemon' utility operates in two modes.

Local debugging:
	The 'wanpipemon' utility is located on the same
	machine as the WANPIPE card.  
	
	Thus, the wanpipemon utility needs only the 
	interface name (eg: wp1_fr16) to reach the driver.

	/usr/sbin/wanpipemon -i wp1_fr16 -c xm


Remote debugging:
	The 'wanpipemon' utility is located on a network
	(LAN or WAN) and must use the UDP protocol to
	reach the WANPIPE card.

	In this case an IP and UDP addresses must be
	specified, such that the packet will pass through
	the WANPIPE driver!

	Meaning a POINTOPOINT address must be used instead
	of the LOCAL IP address.  
	
	The UDP port was specified in WANPIPE configuration 
	file. (Default=9000)

	/usr/sbin/wanpipemon -i 201.1.1.2 -u 9000 -c xm


GUI Mode Operation
==================

The GUI mode is based on ncurses libraries, thus it
will work both in Terminal or Xwindows mode.  

	/usr/sbin/wanpipemon -g

Without any other arguments the GUI will offer a list
of network interfaces, for local debugging, or will
ask for an IP/UDP address, for remote debugging.

Use menu's to navigate through available commands.



Common Statistics
=================


Modem Status (-c xm):

	(wanpipemon -i if_name -c xm)	
	
	Must be DCD=HIGH and CTS=HIGH if not there is
	ether a cable problem or the sync line is
	not turned ON.

Comm Error Stats (-c sc):

	(wanpipemon -i if_name -c sc)

	Check for CRC and Abort errors. If errors 
	are incrementing, there is a line issue.
	
	Possible reasons: CSU/DSU misconfiguration
			  on local or remote side.
			
			  Noisy/Bad line.


Line trace (-c tr):

	(wanpipemon -i if_name -c tr)

	Make sure thare are incoming and outgoing frames.
	
	If frames are outgoing and none incoming:
		
		Frame relay: Check signalling (ANSI, LMI)
			     
			     Make sure ISP uses IETF or CISCO 
			     data encapsulation.
			     
		Other prot:  Possible CRC errors in TX 
		             direction. Contact your ISP.

			  
	If frames are both incoming and outgoing but 
	protocol is still down:

		Run trace in Interpreted mode (-c ti) and
		make sure that the incoming protocol is
		indeed the one you are configured for.


Wanpipe Kernel Messages

	/usr/sbin/wanrouter messages
or
	tail -f /var/log/messages

	All line/protocol events will be displayed in 
	the kernel logs.
