Appendix D Troubleshooting and SunATM Error Messages 103

The information given to ifconfig comes from the /etc/opt/SUNWconn/atm/

atmconfig and /etc/opt/SUNWconn/atm/aarconfig files. Check the entries

inthose files that apply to this interface and verify their contents. For descriptions

of the file formats, see “Editing the atmconfig File” on page42, and “Editing the

aarconfig File” on page44, or the atmconfig(4) and aarconfig(4)man

pages.

3. Check the setup_state with aarstat(1M).

This command will provide information about the Classical IP status on your

interface. The setup_state refers to the completion of the aarsetup program.

■If the setup_state is setup-started, it indicates that the aarsetup program has

not completed; it may be delayed by slow switch responses, or failed attempts to

that the local address given for your interface in /etc/opt/SUNWconn/atm/

aarconfig is unique to this switch. Using $myaddress and the reserved server

addresses is a good way to guarantee that all addressesare unique. After making

any changes to /etc/opt/SUNWconn/atm/aarconfig,runaarsetup again.

■If the state is not setup-started or setup-finished, verify that the addresses and

interfaces in /etc/opt/SUNWconn/atm/aarconfig are valid, and run

aarsetup again. If you see any error messages, check their meaning in “Error

Messages” on page 110.

4. Verify the interface_state in aarstat(1M).

The interface_state is either up or down, and reflects the linkstate given in the

output of qccstat. If the linkstate is DL_ACTIVE, the interface_state is up;

otherwise, the interface_ stateis down. If aarstat indicates that the

interface_state is down, try the suggestions for a linkstate that is not

DL_ACTIVE, given in “ToDiagnose Generic Configuration Problems” on page 101.

5. Make sure Classical IP is configured correctly.

The aarstat(1M) output lists several parameters for Classical IP.The field

arpcsmodelists whether Classical IPis running as a client, a server, or standalone (a

client with no server configured). Verifythat this is correct; if it is not, check your /

etc/opt/SUNWconn/atm/aarconfig file entries.

6. If the system is a Classical IP client, verify the server connection.

On systems running in client mode, aarstat also provides information about the

server.Verify the server address, and that the server_state is connected.

7. If the server_state is no-connection or connecting.

The system is likely having a problem establishing a connection to the server.Verify

that the server address is correct, and that there is a system on the network which

has registered that address. The server and applicable switch ports must also be

configured to support UNI signalling, also called Q.2931 or Q.93b.
