L-FLS-A901-4S= Overview
Check the SFP port group
The licensing table associates this feature with SFP ports 8–11 on the supported A901-4C chassis. It is not the copper-port upgrade and does not add four physical transceivers to an order.
Specify electronic fulfillment precisely
Cisco distinguishes the L-prefixed electronic article from its paper-license counterpart. Include the full order code, existing chassis PID and installed license inventory in the request. Ask for entitlement eligibility and delivery evidence before accepting the quotation, and source any required optics separately.
Do not carry this license onto a different router by name alone
Port-upgrade compatibility is chassis-specific. A similar number in another ASR family is not an acceptable substitution. Have the implementation team confirm the actual port group and required feature before changing the installation.
Legacy support boundary
The exact code appears in Cisco EOL13051; its published hardware/feature support endpoint was June 30, 2025. Do not infer ongoing manufacturer support or availability from this retained product listing.
