It shows what CoS values set various DSCP ToS values. This can be useful if you receive a CoS tagged frame and then want to have the IP packet reflect the L2 CoS value in the IP ToS. The default translation map changes the 8 CoS values into their (more or less) equivalent DSCP (or IP Prec) values, but you can change the translations, if you so desire.
The common reason for such a translation, many pure L2 switches that support QoS only can work with the CoS value, not the IP ToS. Further, CoS comes and goes with VLAN tags. Given these two issues, it can be convenient to be able to set a CoS value based on ToS or the converse.
