Card Pca200e (fwd)

[Magnos Martinello - COPPE/Sistemas-UFRJ <magnos@land.ufrj.br>]

Hi,
	we have tested PCs AMD-K6 with 128Mb of Ram with 	
two ATM configurations:
	- Linux Red-Hat 5.2;
	- Kernel version 2.1.106;
	- Atm-Linux version 0.38;
	- Pca200e driver version 0.4;
	- ASX-1000 Switch; and

	- Kernel version 2.2.1;
	- Atm-Linux version 0.55;
	- Pca200e driver version 0.4;
	- ASX-1000 Switch; 

	We tried PVC setup as the first simple step.
	We configured the PVCs across the ATM switch and locally,
without no problems. Just after, we send pings to a Solaris (which
has been working fine on ATM). 
We verified that the PC sent over AAL5, but received over 
AAL0, getting AAL0 RecErrors. At Solaris side,
the workstation received the cells correctly, interpreted them as pings,
and returned them over AAL5, accordingly. 
We observed that the same number of cells were received and transmitted.
	Here are some of the collective diagnostic statistics after
some ping attempts:

Itf       TX_okay   TX_err    RX_okay   RX_err    RX_drop
  0 AAL0         0         0         0      2037         0
    AAL5      1648         0         0         0         0
	
	It is shown by atmdiag.

	Looking at /proc/atm/pca200e:0 we got the following information:

	We had started the following commands:

        atmarpd -b
        atmarp -c atm0
        ifconfig atm0 192.168.1.1 netmask 255.255.255.0 up
        route add -net 192.168.1.0 gw 192.168.1.1 netmask 255.255.255.0
        atmarp -s 192.168.1.3 0.0.110, 

	which we did a bidirecional VCC on the switch between the two
machines.
	
	Do you have any idea?
	
	Thanks
