Performing a Memory Dump 147

cIf 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.

dIf 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.

8Select 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.

9Enter 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.

Obtaining the MAC You need to obtain the media access control (MAC) address of the Address 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:

1At the Enterprise OS # prompt, enter:

SysInfo

2Record the MAC address for port 1 when it is displayed. You will use this number in the next procedure.

Creating a File for the Some UNIX TFTP servers do not have the capability to create files if they Memory Dump 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.
