ROUBLESHOOTING

To create a memory dump file, follow these steps:

1 On a UNIX TFTP server, create a file with the name dmXXXXXX.dmp, 

where XXXXXX is the last six characters of the MAC address of the 
Ethernet port (port 1) of the SuperStack II bridge/router.

For example, if the last six characters of the MAC address of the 
bridge/router are 06BA6A, enter:

2 Ensure that all users have permission to write to the target directory and 

filename. To determine this on a UNIX system, enter:

3 To change write access permissions on a file or directory, enter:

See the UNIX system documentation if you have any problems.

To verify that a TFTP transfer can occur from the SuperStack II 
bridge/router to the TFTP server, follow these steps:

1 Obtain a listing of the files on the SuperStack II bridge/router to select 

one to transfer using:

df <directory>

2 If you are using a UNIX TFTP server, create a zero byte file with the name 

of the file you selected, and with the proper permissions, using:

touch <filename>

chmod 666 <filename>

3 Transfer the selected file from the bridge/router to the TFTP server using:

COpy [<device>:]<src_filename> [<device>:][<dest_filename>]

For example, to copy a source file named system to destination /dump/ 
using the TFTP server at IP address 139.88.132.192, enter:

4 Verify that the file was transferred to the correct location on the TFTP 

server.
