Installation and Configuration Errors
This section discusses installation and configuration error messages and includes explanations and recommended actions.
Use the following checklist to ensure installation procedures were followed correctly during a remote mount installation:
Some of the most common errors during the configuration process include the following:
The following error message might occur when using the CiscoWorks NetView Interface. If you cannot find an error message, check the troubleshooting section in the 7.0 SunLink SNA Peer-to-Peer Administrator's Guide.
The SNA P2P gateway was not added to the NIS Services list. The machine running SNA Peer-to-Peer is acting as a slave server for the NIS Server.
Add the IP address and machine name to the list of machine names on the NIS Server.
The following notes highlight some of the troubleshooting tips you can use to solve PCA problems.
If an authenticationFailure trap is generated by the snmpd when PCA is installed, you can disable it in one of two ways:
The following error messages might occur when using the CiscoWorks NetView Interface. If you cannot find an error message, check the troubleshooting section in the 7.0 SunLink SNA Peer-to-Peer Administrator's Guide.
This message may appear in response to a misspelled shomibvar RUNCMD request. It might also occur if the router does not recognize or support the specified group MIB variable, if you have entered an incorrect interface name, or if SNM is not running.
Refer to Table 6-2, which describes supported group MIB variables. Also, check if SNM is running.
The netset RUNCMD request has failed. The SunNet Manager property sheet for this device is missing the SNMP Write community string. CiscoWorks requires that the property sheet contain the SNMP Write community string for RUNCMD requests.
Check the SNMP Write community string under the SNM console's property sheet. If there is none, enter the device's current SNMP Write community string. If you do not know the SNMP Write community string, use the CiscoWorks Device Management application to look it up. You can also use the getconf RUNCMD to look for the string, since the configuration file includes the community strings for the device.
The SNM snm-cmd displays a generic error message for a variety of errors.
If you receive this generic error, check the following list for possible reasons:
RUNCMD Error Messages and Troubleshooting
This section discusses RUNCMD errors and include explanations and recommended actions.
Misspelled or Unsupported Commands
If the NetView operator sends a misspelled or unsupported command (for example, wrongcmd) CiscoWorks NetView Interface will respond by sending an error message to the NetView console:
You might also receive this error when the RUNCMD Server is not registered.
If the NetView operator misspelled the command, a syntax usage string appears:
Retry sending the request. If it is a RUNCMD Server connection problem, restart the RUNCMD Server. Refer to the section on "RUNCMD Server" in Chapter 5 for instructions on starting the Server.
This section contains updated information on the Sun Administration manual contents on how to perform a gateway trace.
Fore tracing capabilities, perform the following steps:
Step 1: Edit your SNA Peer-to-Peer configuration input file, p2pconf_custom, using the text editor of your choice.
Step 2: Turn on the DB_MSG (debugging messages) parameter in the PCA event table. The following values should be set in DB_MSG:
Step 3: Save the table.
Step 4: Restart PCA by clicking on the PCA glyph and pulling down to Tools to select PCA Start.
Step 5: To turn debugging off, return all value settings in the DB_MSG parameter back to zero (0).
Step 6: Repeat steps 3 and 4.
This section contains information on some Token Ring support issues.
To determine if your Token Ring interface is up, enter the following command at the UNIX prompt:
The current Token Ring status displays. Ensure that your Token Ring interface is configured correctly in your /etc/rc.local file.
If you plan to use both interfaces E0 and T0, you must assign a different MAC address to the Token Ring. This is referred to as a locally administered mac address.
To add the locally administered MAC address for your SPARCstation, add the following two lines to the rc.local file:
The maximum transmission unit (MTU) size set on the SUN workstation must be same as the MTU used on the Token Ring. If this is not the case, you will receive error messages regarding MTU size on the console. Sun drops the packets where MTU size is not equal to size it is configured.
To change the MTU size, perform the following steps:
Step 1: Edit the sys/netinet/token_tr.h file using your favorite editor. For example, to edit the file using vi:
Step 2: Change the TR_LEN_MTU variable (this is a index into the table) to whichever variable is appropriate for your Token Ring.
Step 3: Save the file.
Step 4: Change directories to the kernel configuration directory.
Step 5: Run make to update the kernel:
Step 6: Copy the kernel to root.
Step 7: Reboot your workstation. You can use L1A or any other method of rebooting.
This section describes troubleshooting gateway errors.
After you run the startp2p script, this message might indicate that the software link to the IBM front end processor (FEP) is not complete. There may be an SNA Peer-to-Peer configuration error, or the Token Ring (or SDLC) may be incorrectly configured.
Check your customized p2pconf file for configuration errors. Also check the Token Ring or SDLC configuration.
