Cisco maps the 10gigUpgrade feature to the A901-6CZ chassis family. Its port table identifies TenGig0/1 and TenGig0/2 as the relevant SFP+ interfaces. Do not apply the ASR 901 order code to an ASR 9000 platform.
Collect the exact chassis PID, software release and existing license state. Have the proposed entitlement checked against the manufacturer licensing table before accepting fulfillment. The feature license does not supply optics, cabling or router hardware, and a physical fulfillment description does not make it a physical port module.
EOL13051 includes this exact article. Its end-of-sale date was June 29, 2020, and the hardware/feature support endpoint was June 30, 2025. Treat a request as a legacy entitlement review; do not assume new Cisco fulfillment or current TAC coverage.
