Why Packet Loss Occurs on the Counter Receiving Test Frames Configured as Response Mode on the LOM Board

Publication Date:  2012-07-25 Views:  43 Downloads:  0
Issue Description
Send test frames when bidirectionally send configuration response frames, and packet loss occurs in the statistics. Why? 
 
Alarm Information
Null 
Handling Process
During deployment commissioning, configure the boards so that they only transmit test frames to each other or configure single-NE response. 
 
Root Cause
The PL251 chip can buffer only one GFP management frame. The two boards are configured so that they transmit services to each other and work in the response mode. In this case, the test frames transmitted by the opposite end and the response frames returned to the local end preempt the buffer. As a result, this problem occurs when the test frames and response frames arrive at the same time. Tests show that the rate of frame loss is 3%. By default (response frames not sent), the two boards do not send packets to each other. In the response mode, packet loss does not occur when the single node sends packets to itself. 
Suggestions
