Steps for documenting data loss problems

Determine the source of the data loss.

Before you begin

To determine where the data packets are being lost, use the LIST MODIFY command for the SNALINK LU6.2 address space. See Using the SNALINK LU6.2 subcommand for details. When listing the connection status, the number of packets sent and received over the connection since establishment is displayed in the report.

Procedure

Perform the following steps:

  1. Record the current packet count for the SNALINK LU6.2 devices in the network that support the LIST MODIFY command.
  2. Issue the PING command on one end of the connection. In a correctly functioning network, PING sends a data packet to the other end of the connection, which then sends a response data packet back to the PING command.
  3. Use the updated packet counts to determine how far the packet went.
  4. Issue the PING command from the other end of the connection.
  5. Use the updated packet counts to determine how far the packet got.

Results

Tip: IP packet trace, as described in Using IP packet trace, can also be used to trace and validate the IP data packets as they enter and leave the SNALINK LU6.2 address space.
