Need some help. I have a 7206 router with a DS3 serial link on one port. I have noticed quite often that when the input rate on the link is at the maximum the rxload figure is low, eg. 19/255 rather that closer to 255/255. I am also using mrtg to monitor bandwidth usage. Mrtg also shows the usage at around 3Mb/s when it should be around 45Mb/s. I am using IOS 12.1(4) Enterprise edition. Has anyone encountered any similar problem?
