88APPENDIX A: TROUBLESHOOTING

 

There is a problem with the installation of the Enterprise OS Upgrade

 

Utilities. The location of the Enterprise OS Upgrade Utilities was not added

 

to the path environment variable or the directory does not contain all the

 

required programs.

 

Meaning:

The installation process cannot find the utilities because it does not

 

 

know where to look for them.

 

Action:

Check that a location for the utilities was specified in the path

 

 

environment variable.

 

There is a problem with the installation of the Enterprise OS Upgrade

 

Utilities. The version numbers of the Enterprise OS Upgrade Utilities are

 

not consistent.

 

Meaning:

The bcmdiagnose utility has assumed that the version of the

 

 

Enterprise OS Upgrade Management Utilities in bcmcommon.sh is

 

 

correct and has checked that each executable utility has the same

 

 

version number. At least one utility is different.

 

Action:

Check that you have specified version number for the utilities you are

 

 

installing correctly.

Determining

Pinging <IP address>

Connectivity

Meaning:

This is an introductory message that appears when the utilities are

 

 

attempting to reach a bridge/router with an IP address specified on

 

 

the command line.

 

Action:

None.

 

The NETBuilder did not respond to a ping. Make sure the IP address or host

 

name is correct and that the NETBuilder is reachable via IP.

 

Meaning:

The device that the utilities were trying to reach did not respond.

 

Action:

Ensure the device can be reached using IP.

 

The NETBuilder responded to ping.

 

Meaning:

The device which was specified in the IP address is reachable.

 

Action:

None.

Validating the SNMP

Testing SNMP read access

Service Configuration

Meaning:

This is an introductory message. Check to see if the SNMP Service is

 

 

active on the bridge/router.

 

Action:

None.

 

The NETBuilder is not responding to SNMP get requests. Ensure that the

 

SNMP Service is configured on the NETBuilder and that you have read and

 

write access via SNMP. Also check the values of the community strings in

 

the /etc/snmp.cfg file. They should match the NETBuilder’s SNMP

 

community strings.

 

Meaning:

The bcmdiagnose utility has attempted to verify whether the

 

 

bridge/router specified by the <IP address> value has been configured.

 

Action:

Configure the SNMP server on your bridge/router to allow read access

 

 

to your network management station. See the Network Management

 

 

chapter in Using NETBuilder Family Software.
