We are using Router 7609-S
sh interface Gi3/48 ------ shows only the present link load and last 5min input/output rate.
Is there any command to display the link load, input/output rate history, say for the last 24h.
You can change it with command load-interval under interface.
Although I'm not sure whats the max interval you can use.
Try ? after load-interval command and it will show you the min-max values.
The maximum time for load-inteval is 600 seconds only. May be you can use MRTG where you can see graphs of utilization for any duration..say it could be last one month also.
Or you can try some other tools ..I am not sure if available for free but for sure from router only it is not possible.
