5thGen Line Cards 400GE

[rainow]

Hi there 
Could anyone explains about "Five of the 20 ports can be upgraded to 400GE through a license on a per-port basis" refers to cisco https://www.cisco.com/c/en/us/products/collateral/routers/asr-9000-series-aggregation-services-routers/datasheet-c78-743580.html 
i wanna use a9k-20hg-flex-tr lc and wanted to be sure about how can i use the 400ge ports
i saw some license on some sites with s-a9k-400ge-enable. do i need that?
i also dont sure if i use 400ge port can i have 100g ports also?
and how exactly 
for example if i breakeout port 0 and its gives me a fourhundredge and can i use port 4 to 20 for 100g at the same time?

best regards

Hello @rainow 

A9K-20HG-FLEx can physicaly host 20 QSFP ports, but the usable mix depend on licensing and the total bandwidht cap of 2 TBps per card _ so you can run all 20 ports at 100G, or instead license up to 5 ports to operate at 200G or 400G, and still use the remaining ports at 100G, as long as the aggregate never exceeds that 2T.

-> S-A9K-400G-ENABLE license is required for each port you want to bump up to 400G, and the rest continue working at 100G without additional licenses.

Thanks for your help M02@rt37 

Then why cisco didnt mention anything about S-A9K-400G-ENABLE license in docs?

Separate datasheet.

That’s the reason why it is preferable to check that in details with your Cisco Parnter.
