COTD: show bandwidth contracts

Using bandwidth contracts? Want to see what's happening with the different queues?

1 1 20000000 0 625000 0/0
1 2 2000000 0 62500 0/0
So what does this mean?
Firstly, look for the line with CPU=1 (CPU=0 is internal to the control plane). Then you have:
Contract: the contract ID in the command output of ‘show aaa bandwidth-contracts’.
Policed: the number of packets being dropped.
Avail Bytes: Not important
Queued Bytes/Pkts: Number of bytes/pkts currently being queued.
Note, we are doing traffic shaping. I.e. If the user is sending traffic above contracted rate, we will queue the packets and release them at contracted rate. Traffic will be policed/dropped (as shown in the ‘Policed’ column) if the user bursts above the contracted rate. This is a bit more TCP friendly then strict policing (or UPC using ATM terminology).
Related commands:
- Use "show user " of a user to see if a bandwidth contract is assigned.
- To find out what contracts have been configured: "show aaa bandwidth-contracts"
