Hi
You dont need licensing. But it is important to know if you have Cisco ASR 1000-SIP10 or Cisco ASR 1000-SIP40.
Look the information below:
• Cisco ASR 1000-SIP10—This SIP supports:
• 4 half height (¼ Rate or full rate or combination) SPAs with up to 16 ports per SPA
• 2 full height (¼ Rate or full rate or combination) SPAs with up to 32 ports per SPA
• 2 half height and 1 full height comb in at on that does not exceed 64 ports
• Up to 10 Gbps of oversubscription
Cisco ASR 1000-SIP40—This SIP supports:
• 4 half height (¼ Rate or full rate or combination) SPAs with up to 24 ports per SPA
• 2 full height (¼ Rate or full rate or combination) SPAs with up to 48 ports per SPA
• 2 half height and 1 full height combination that does not exceed 96 ports
• Up to 40 Gbps aggregate bandwidth from the four SPA bays
• ESI bandwidth of 11 to 46 Gbps
• Ingress buffering at 128 MB and egress buffering at 6MB
If your router is SIP10, basically you can have one port 10 GE using SPA.
For SIP40, you can have up to 4 10GE using SPA.
