Troubleshooting—Throughput
Verify the current maximum throughput level with the
show platform hardware throughput level
command.
Troubleshooting—Instruction Extensions
Some x86 processors support instruction extensions for performing certain cryptographic transforms. Using
these instructions is more efficient than not using them. The Cisco CSR 1000v/ISRv detects at runtime if the
instruction extensions are available and will use them if they are available. To determine if the extensions are
available, enter the
show platform software system all
command. (See the example below.)
If the output shows that "Crypto Supported" is "No", then the Cisco CSR 1000v/ISRv may not exhibit the
expected throughput. This is an issue with either the underlying physical hardware or the hypervisor. Check
to see if the underlying physical hardware is capable of exposing the extensions and also check to see if the
hypervisor can expose the extensions.
If the output shows that "Crypto Supported" is "Yes", then the Cisco CSR 1000v/ISRv should provide the
expected throughput, because the physical hardware and the hypervisor can expose the extensions.
In the following example, "Crypto Supported" is "Yes". Therefore the cryptographic transforms can use
instruction extensions, and perform efficiently.
