A9K-36X10GE-TR vs A9K-24X10GE-TR - is the 36-port card oversubscribed?

We are trying to understand the difference between these 36-port and 24-ports cards.

Is the 36-port card considered to be oversubscribed as compared to the 24-port card?

Is is RSP dependent?

Any other details would be helpful.

Thank you.

The fabric on the ASR9K (on the RSPs) runs in active/active, so both RSPs fabric are used at the same time.

 

The 24x10 card offers more NPs but fewer ports per NP, it is undersubscribed with 3 ports per NP, whereas the 36x10 card uses all the BW of the NP to support 6 ports per NP. So in terms of performance both cards should be able to handle linerate.

 

Thanks,

Neither card is oversubscribed, the only difference is the number of NPs and ports.

You can check the NP mapping with show controller np ports all loc <lc>.

 

With dual RSP440 you have 440Gbps/slot.

Sam,

In an ASR-9010 chassis, when DUAL RSP440's are used, one of them is considered "standby".

So even with one RSP440 set as "satndby", the 2 RSP's provide 440G per slot?

 

If a system is running DUAL RSP440's, does the 36X10G card offer the same performance as the 24X10G card?  Do all 36 ports have the same performance?
