The file "test3.com" was not created with read access. Make sure <tftpboot_dir> has full read/write/create file permissions.

Meaning:

When the UNIX copy command created the file, read access was

 

not assigned.

Action:

Assign full read/write/create file access permissions to the directories.

The file "test3.com" was not created with write access. Make sure <tftpboot_dir> has full read/write/create file permissions.

Meaning:

When the UNIX copy command created the file, write access was

 

not assigned.

Action:

Uploading an Upgrade File

Could not remove "<ipaddress> DNSname>:a:/test3.com". Check that the

NETBuilder media is not write protected and that "<ipaddress>

DNSname>:a:/test3.com" is not the name of a directory on the NETBuilder.

Meaning: The bcmrm utility could not delete the file on the bridge/router.

Action: Make sure that your floppy disk write protect tab allows writing to the diskette.

Copying TestFile from the NMS to "<ipaddress> DNSname>:a:/test3.com".

Meaning: This is a status message.

Action: None.

The bcmcp command could not write the file "testfile" on NBAddress or DNS name. Make sure there is a flash or floppy drive installed and that it is not write protected.

Meaning: The bcmcp utility has been denied write access to the bridge/router.

Action: Make sure there is a flash or floppy diskette installed and that it is not write-protected.

The file "<ipaddress> DNSname>:a:/test3.com" is not present on the brouter even though bcmcp did not report an error.

Meaning:

The bcmtest utility could not locate the file on the bridge/router.

Action:

Check with your systems administrator.

The checksums of "test3.com" and "<ipaddress> DNSname>:a:/test3.com" are different even though bcmcp did not report an error.

Meaning:

The bcmsum utility reported differing checksums on the local and

 

remote test files.

Action:

Check your network connection for possible corruption on the line.
