The value is associated to the load-interval from the monitored interface.
The maximum value allowed is 600 seconds.
Default setting:
Rack1R1#sh ip nbar protocol-discovery | i Bit Rate
5min Bit Rate (bps) 5min Bit Rate (bps)
5min Max Bit Rate (bps) 5min Max Bit Rate (bps)
Change the load-interval to 30 seconds.
Rack1R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Rack1R1(config)#int f0/0
Rack1R1(config-if)#load-inter 30
Rack1R1(config-if)#do sh ip nbar protocol-discovery | i Bit Rate
30sec Bit Rate (bps) 30sec Bit Rate (bps)
30sec Max Bit Rate (bps) 30sec Max Bit Rate (bps)
See the available values:
Rack1R1(config-if)#load-inter ?
<30-600> Load interval delay in seconds
If you want to have statistical information, I recommend configuring NetFlow.
