SPA Support
Q.
Which SPAs do the SIP10 and SIP40 support at the time of first availability?
A.
Please refer to the Cisco ASR 1000 SPA supportability matrix.
Functions
Q.
Do the Cisco ASR 1000 Series SIP10 and SIP40 participate in forwarding decisions?
A.
No. The Cisco ASR 1000 Series ESP makes all forwarding decisions. However, the SIP10 and SIP40 support
ingress classification and buffering to allow interface oversubscription.
Q.
Will the upgrade of one SPA driver affect the operations of other SPAs in the same SIP? How about other
SPAs in the same platform?
A.
No. The modular design of the Cisco ASR 1000 Series Aggregation Services Router allows each SPA driver to
operate as an isolated entity. Each driver is individually upgradeable and does not affect other SPAs in the same
SIP, nor will it affect other SPAs in the same platform.
Q.
Is online insertion and removal (OIR) supported on the Cisco ASR 1000 Series SIP10 and SIP40?
A.
Yes. Both the Cisco SIP10 and SIP40 support OIR, as do the SPAs housed by the SIPs.
Q.
What are the functional differences between the SIP10 and SIP40?
A.
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.
