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. For more information, see the Quality of Service Solutions Configuration Guide Library,
Cisco IOS XE Release 3S.
Managing Memory Upgrade Licenses (Cisco IOS XE Release 3.11S and Later)Beginning with Cisco IOS XE Release 3.11S, memory upgrade licenses can be used to add available
memory to the Cisco CSR 1000V. The additional memory is allocated to IOSD, an internal processing
component on the router, to increase scalability. The memory upgrade license does not add memory for
the VM itself. The actual memory added to IOSD depends on the available system memory.
The memory upgrade license is available only through a Cisco service representative, and can be used
only if you have selected licenses already installed.
You can upgrade the memory by installing the memory upgrade license using the standard license
installation procedure. You must reboot the Cisco CSR 1000V to increase the maximum memory
supported.
