Check “load” numbers. These are defaulted to a rolling average of 5 minutes and displayed as a factor of 255 (2^8, but counting from 0 not one). So a load of 255/255 would be completely saturated.
You can change this 5 minute default to a 30 second rolling average by going to the interface in question and issuing the command “load-interval 30” This a very useful process when deploying BGP. The tx/rx of course is transmit load versus receive load, which can also be extremely handy in understanding certain traffic issues (BGP load sharing for example).
