ISR 4000 Performance and Boost licenses?

Hi all. I have a question. I have default throughput license for ISR4451 and I want to upgrade to the boost license. I have to buy the boost license only or two licenses at a time (performance+boost)?

Negative.  If you buy the boost license it puts you up at the boost level, bypassing the performance level.  You do not need to purchase performance AND boost licenses.  We have done exactly this (just buy the boost to get the entire throughput unlocked) on many ISR4331 routers.  Hope this helps...

What kind of throughput do you see with the license. I was thinking of getting a few rather than go to 4431's with the performance license for cost savings.

Joseph,

 

Are there SLA/packet delivery implications to utilizing the boost features?  Cisco previously conveyed that licensing limitations and performance capping strongly protected one IOS-XE feature, service, micro-service, or daemon from impacting another, by putting strong resource protections in place.  This supposedly provided higher performance predictability when enabling features such as NAT, IPSEC, PBR, NetFlow/FnF, etc.  Are we as safe from an SLA guarantee perspective in an environment with these enhanced features enabled along side active boost licensing?

P.S.  Colin, I hope all is going well my friend!  Keep in touch

Ah, good question about SLAs!

You're lose SLA guarantees with a boost license. Basically, you're running the device like the prior gen of ISRs. Capacity/throughput can vary widely based on your traffic mix and configuration.
