Performing a Memory Dump
147
If necessary, select Gateway from the Dump Destination menu and 
enter the IP address of the default gateway leading to the network on 
which the TFTP server resides.
If subnet masks are in use, select Subnet Mask from the Dump 
Destination menu and enter the subnet mask associated with the IP 
network attached to the Ethernet port.
Select Dump Destination Directory on the Dump Destination menu to 
configure the location on the TFTP server to which the dump file will go.
The default destination is /dump.
Enter the target directory on the TFTP server. 
Usually, the target directory is the default TFTP directory. For example, if 
the TFTP directory is /home/TFTPdir, and the target directory configured 
on the bridge/router is /dump, then the actual target directory is 
/home/TFTPdir/dump. Make sure this directory exists on the TFTP server, 
as it will not be created by the bridge/router, or the TFTP process when a 
TFTP transfer is initiated.
10 Type Q repeatedly to exit the System Configuration menus and return to 
the Enterprise OS # prompt.
Obtaining the MAC
Address
You need to obtain the media access control (MAC) address of the 
SuperStack II NETBuilder SI bridge/router. This is necessary because the 
system creates a dump file on the TFTP server named dmXXXXXX.dmp, 
where XXXXXX are the last six characters of the MAC address of the 
Ethernet port (port 1) of the bridge/router.
To display the MAC addresses, follow these steps:
At the Enterprise OS # prompt, enter:
SysInfo
Record the MAC address for port 1 when it is displayed. You will use this 
number in the next procedure.
Creating a File for the
Memory Dump
Some UNIX TFTP servers do not have the capability to create files if they 
do not exist, but can overwrite an existing file. Therefore, you must first 
create a file with the expected dump file name on the UNIX TFTP server.
Before beginning this procedure, make sure the TFTP server is running. 
On a UNIX system, the ps command with appropriate arguments provides 
a listing of the current processes. See your documentation pertaining to 
the IP stack on the TFTP server if you have any problems.
