BGP4 Diagnostic Buffers

The device stores the following information:

• The first 400 bytes of the last received packet that contained an error
• The last NOTIFICATION message sent or received by the device

This diagnostic information can be useful if you are working with Extreme Technical Support to resolve a problem. The buffers do not identify the system time when the data was written to the buffer. If you want to ensure that diagnostic data in a buffer is recent, you can clear the buffers.

If you clear the buffer containing the first 400 bytes of the last packet that contained errors, all the bytes are changed to zeros. The Last Connection Reset Reason field of the BGP4 neighbor table also is cleared.

If you clear the buffer containing the last NOTIFICATION message sent or received, the buffer contains no data.

You can clear the buffers for all neighbors, for one neighbor, or for all neighbors in a specific peer group.
