910.0. "CAn't associate with remote host?" by CSC32::A_LICAUSE () Thu Apr 17 1997 11:26

    Customer is running dunix v4.0 and is attemtping to setup a connection
    to a PVC that has already been configured, according to the customer,
    in the switch.
    
    She has a valid entry for the Cisco in both /etc/hosts and
    /etc/atmhosts.  When she does atmarp -a she does not see an entry
    for the Cisco.
    
    If she enters atmconfig vclist, she sees entries for vci and vpi of
    0 and 151 respectively.
    
    I asked her to force an arp entry using atmarp -s atm_addr ip_addr
    cisco permament.  She now has an atmarp entry for the Cisco, but
    when she tries they command:
    
    	atmarp -v +vc 0 151 cisco_name.blah.blah.blah or Cisco_address
    
    she gets the error:  "cannot associate vc vip=0 vci=151 with entry
    cisco_name or cisco_address"
    
    I'm new at setting up ATM on dunix so please tell me what I may be 
    missing.  We have gone over the other preliminary setup information
    and she does have an IP address associate with lis0.
    
    Any help appreciated!
    

    To set up Classical IP over a PVC, do the following:
    
    1. Configure the PVC on the switch, for example VCI 99
    
    2. On each of the two hosts:
    	atmarp -c lis=0 driver=lta0
    	ifconfig lis0 <ip address> netmask <netmask> up
    	atmconfig +pvc driver=lta0 converge=atmip vpi=0 vci=99 selector=0
    
    atmarp -a should then show an entry for the PVC.  The remote IP address
    is obtained from the InARP messages exchanged when Classical IP starts
    up on the PVC.  atmarp -v is a manual way of forcing this information,
    but it shouldn't be needed.
     
    The most common mistake is omitting the selector parameter from
    atmconfig +pvc.
    If you have multiple LIS's, the selector determines which LIS the PVC
    is associated with.  I think the selector number always equals the LIS
    number.
    
    There is no need for anything in /etc/atmhosts, since ATM addresses
    only apply when using SVC's.
    

    Thanks very much.
