Hi Ibrahim


Cisco ASR 1004 with 2 SIPs supports 8 half-height SPAs.

The 10- and 40-Gbps Cisco ASR 1000 Series SIP can support up to four half-height or two full-height SPAs or two half-height and one full-height SPAs.


http://www.cisco.com/en/US/prod/collateral/routers/ps9343/qa_c67-496324.html


Hence, as SPA-1X10GE-L-V2 is a full height SPA, 4 such SPAs can't be supported in a single SIP module.

Hi Ibrahim


Sorry...here is the correct one:


SPA-1X10GE-L-V2  is HH.

SPA-10X1GE-L-V2 is FHeight.


If you are making use of half-height SPAs, you can use upto 4 half height SPA's in a SIP-10 module. But in case you want to make use of full height SPAs, you should use upto 2 full height SPAs.


Cisco ASR 1000-SIP10-Supports:

- 4 half height (Rate or full rate or combination) SPAs with up to 16 ports per SPA


-2 full height (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



The SIP40 allows up to 40 Gbps of bandwidth capacity between the SIP carrier card and the ESP forwarding engine, as opposed to 10 Gbps for the SIP10.

Max ESP throughput that you could get on ASR1004 chassis is 40 Gbps (20Gbps in and 20Gbps out---> 20G unidirectional & 40 G bidirectional) which requires ESP40G forwarding plane and SIP40 carrier card.


You can refer to this document to understand this better:
