If so, check the IP parameters you configured on the 8285 ATM Control Point to ensure that they are correct. Pay particular attention to your IP subnet and your IP subnet mask.

If you are not registered with the ARP server, try the steps outlined in 7.1.3.2, ªCorrecting ARP Registration.º

7.1.3.1 Checking ARP Server for Registration

If you are unable to ping the ARP server or any other IP device, check to see if the ARP server is properly registering your IP and ATM addresses.

For AIX ARP servers, this can be checked in two ways:

1.Using SMIT, the Systems Management Interface Tool

2.Using the fast path command arp -t atm -a

Checking ARP Registration via SMIT

To check ARP registration via SMIT, perform the following steps:

1.Log on to the server as root.

2.Key in smit or smitty (the character-based version) and press Enter.

3.Select the following menu items in sequence:

Communications Applications and Services

TCP/IP

Network Interfaces

List SVCs over an ATM 100 Network or List SVCs over an ATM 155 Networkdepending on your interface

Checking ARP Registration via Fast Path Command To check ARP registration via the fast path command, perform the following steps:

1.Log on to the server as root.

7.1.3.2 Correcting ARP Registration

If the ARP server is not registering your 8285 CIP information, but is registering other CIP devices, try re-initializing the 8285 CIP function by re-entering the SET DEVICE ARP_SERVER command. This will force the 8285 ATM Control Point to go through the CIP registration process again.

If you are still not able to register, check the ARP server address you keyed in and be sure that all 20 bytes of the address explicitly match the ARP servers address.

You have now completed a simple CIP network. You could add additional workstations to the switch. Or you might choose to extend your network by adding another switch.
