To verify the actual throughput, use the following command:
Router# show platform hardware qfp active datapath utilization summary
CPP 0:

In the example, the input rate shown in bold is close to 60 Mbps. The output rate shown in bold is close to 50
Mbps. In this case, the input rate exceeds 50 Mbps, the maximum license rate allowed.
The following command displays the number of packages dropped when the maximum throughput is exceeded:

When the actual throughput level approaches the maximum allowed by the installed license, you will receive
an alert message similar to the following (the message may differ depending on the release version):
Dec 13 22:00:29.699: %BW_LICENSE-3-THROUGHPUT_THRESHOLD_LEVEL: F0: cpp_ha:
Average throughput rate exceeded 95 percent of licensed bandwidth 3 times, sample period
300 seconds, in last 24 hours
When the throughput exceeds the maximum allowed bandwidth set by the license, you will receive an alert
message similar to the following (Cisco IOS XE 3.12S and later):
*Dec 13 22:00:29.699: %BW_LICENSE-4-THROUGHPUT_MAX_LEVEL: F0: cpp_ha:
Average throughput rate exceeded the total licensed bandwidth 50000000 bps and dropped 7
times, sample period 300 seconds, in last 24 hours
You can configure the QoS policies at the interface level to guarantee that high-priority traffic is not dropped.

Managing Throughput Notifications
Beginning with Cisco IOS XE 3.13S, and including IOS XE Denali 16.3.1 and later, you can configure the
Cisco CSR 1000v to notify you when a certain percentage of the maximum throughput level is reached. The
maximum allowable throughput is based on the installed throughput license.
By default, when the Cisco CSR 1000v first boots, the throughput level notification is enabled, and notifications
are sent when the router reaches 95 percent of the maximum throughput level. The throughput level is measured
every 300 seconds. When the router is rebooted, the threshold and interval level settings configured using the
set platform hardware throughput-monitor command are retained.
The following command configures the hardware throughput monitor settings. The
threshold percentage
value represents the percentage of the maximum throughput at which the system notifies you. The valid range
is from 75 to 95, and the default value is 95 percent.
The
interval
value represents how often the system measures the throughput level. The valid range is from
30 to 86400 seconds. The default value is 300 seconds.
set platform hardware throughput-monitor threshold percentage interval seconds
