ATM Adapter Configuration at the ICSI


Currently we are using Fore SBA-200E and Interphase 4615 ATM Adapter with 155Mbit/s Multimode Fiber Interfacee (SC-connector). As our workstations are connected to the BAGNet and MAY network which are both pvc (permanent virtual channel) based networks, we also use pvcs for the local interconnection of our workstations. IP packets are encapsulated using the LLC/SNAP encapsulation method (RFC1483).
Usually network configuration can only be done with root permission, but as our network is an experimental one the group ownership of all needed commands is changed to atmdevel and the set-user-ID bit is set, so all members of this group can change the configuration. Some of the special commands are copied to the /etc/local directory because this is a workstation local directory.

Setting up a New ATM Adapter

To setup a new adapter the following steps must be performed as root:

  1. Install the driver software of the ATM adapter
  2. copy ifconfig in the /etc/local directory
  3. copy route in the /etc/local directory
  4. change the group ownership to atmdevel of these commands and set the set-user-ID flag.
  5. change the group ownership of the following commands to atmdevel and set the set-user-ID flag.
  6. add the following to the /etc/local/rc.HOSTNAME:

PVC Setup and Check

Each adapter has a special command and parameters to setup a pvc. The local interconnection is usually automatically setup during reboot, so only additional connections have to be set up ore dropped. For more Information about these and other commands look at the manual pages. In which workstation which adapter is installed can be found in the ICSI Host Configuration Table.
