4.Verify that an address has been registered with the switch.
The qccstat(1M) command also lists all addresses registered to the interface with the switch. See “ATM Addresses and Address Registration” on page 66, for more information about address registration. If there are no addresses registered, the ilmid daemon on your system is not communicating properly with the switch.
■Verify that there are incoming packets on VC 16 using atmstat(1M).
If there are no incoming packets, the switch is not responding to ILMI requests. Check its ILMI configuration.
■Verify that there are outgoing packets on VC 16 using atmstat(1M).
If you do not see any outgoing packets on VC 16, your interface is not transmitting ILMI packets. Verify that ilmid is running on your system, and if necessary, start it in the background. Starting ilmid with the
5.Interfaces that are not running Classical IP or LAN Emulation will not appear in the output of the ifconfig command.
ifconfig(1M) displays interfaces that have been configured for IP. In order to support IP, ATM interfaces must run either Classical IP or LAN Emulation. Therefore, an ATM interface that is not configured to support IP by running one of these two protocols will not be displayed by ifconfig.
6.Verify the packets that are moving over the network with the /etc/opt/ SUNWconn/bin/atmsnoop command.
▼To Diagnose Classical IP Configuration Problems
1.Check all of the generic configuration points.
These are issues that apply to all SunATM interfaces, so they all must be working in order for Classical IP to work.
2.Verify the output of ifconfig(1M).
Executing the command ifconfig
■If your interface does not appear, an error probably occurred during the boot process.
Check for error messages during the boot process. The meanings and possible solutions for error messages can be found in “Error Messages” on page 110.
■If your interface appears but has incorrect information, verify your configuration files.
