My “Show Run Variations” post sparked an interesting thread on Networking-Forum. I thought it would be nice to make a post with as many useful/little known commands as I can find. I might make a separate page for this depending on how much I can come up with and how frequently updates would be needed. Here we go:

show ip nbar protocol-discovery stats bit-rate top-n 10

This command will show you the top 10 protocols (that NBAR can see) on your router. I use this in an alias called “traffic”. You will also need “ip nbar protocol-discovery” enabled on interfaces you want to see statistics for.


show processes cpu sort

This command will show the sorted CPU usage of all processes running on the router. You could also use “show proc cpu history” to see some ASCII graphs of CPU utilization.
