Displaying the SPA Hardware Type
To verify information about the SPA hardware that is installed in your Cisco ASR 1000 Series Aggregation
Services Routers, you can use the show interfaces command or the show controllers command. There are
several other commands on the Cisco ASR 1000 Series Aggregation Services Routers that also provide SPA
hardware information.
The following table shows the hardware description that appears in the show command output for each POS
SPA that is supported on Cisco ASR 1000 Series Aggregation Services Routers.
