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,
“Correcting ARP Registration.”
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
•
Further Configuration
•
Network Interfaces
•
List SVCs over an ATM 100 Network or ″List SVCs over an ATM 155
Network″ depending 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.
2. Key in the command:
arp -t atm -a
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 server′s
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.
