The connection establishment rate (CER) measures how many TCP connection setup requests received by the target stack become established (that is, how many enter the ESTAB state). The CER value is displayed as a percentage; 100 indicates that all of the connection setup requests that were received entered the established state. A lower value could indicate a routing problem in the network. The CER value is shown only as a diagnostic aid, and its value has no affect on the WLM weight.
