Conference noted::atm

Hi,

by now, I get the link up, and create Elan on alpha, and see the alpha on 
GS/ATM as a Elan client. But the net not work.

Why?

eric

    V4.0B has a few more fixes the V4.0A.  But if you install the ATM
    related patches for V4.0A (which anyone using 4.0A should do), then
    they are equivalent.
    
    You haven't given us enough information to diagnose any problem.  What
    are the exact commands you entered on the Digital UNIX system?  What
    does ifconfig -a show?  How about atmelan show?  How is the other
    system you're trying to contact configured?

1.At the VN900EA, do nothing on it, just setup an ip address 16.168.208.10;
2.At the GS/ATM, my config is:
	elanall 1 -e
	elanall 1 +nv
	lecs -e
	lecs +nv
3.At the Alpha on UNIX4.0b:

    re: .3
    
    Things look fine on the UNIX side (i.e., elan0 is operational).  Can
    you verify that the VN900EA has joined the same ELAN on the Gigaswitch?

    You have the same IP address configured on interface lis0 (Classical
    IP) and elan0 (LANE).  
    
    If you're not using Classical IP, remove the 
    atmarp and ifconfig lis0 commands from your atm.conf.  If you're also
    trying to use Classical IP, then you need different IP addresses (in
    different subnets) for each interface.  The atmarp -h command would
    also be wrong...it has the lis0 IP address as the address of the ARP
    server.
    
    I also didn't see an ifconfig command for elan0 (although the ifconfig
    -a output shows that it was done.

I got it!
I removed the atmarp commands as you said, and add ifconfig for elan0, the 
net is working!

Thank you very much!
