Hi Meena, Eric and Shameel

Thanks for today’s presentation, we’ve learned lots

Please help to reply the following question:

  •  Will it be possible to upgrade DNA essentials to DNA Advantage during a subscription term if customer needs change?­

An upgrade request will have to be initiated by the account manager to Cisco and the difference in the tiers will have to be paid.

Yes- it is possible

Excellent session, thanks to Cisco team.

During Eric's session, i had posted query about Serial port on 1100 routers.

Toan mentioned P1-T availability on C1101-4P whereas Meena said available with restricted regional availability.

If the router is for LTE purpose, will it have any limitation using the same chassis but with serial port?

I couldn't find any info from the deck, can you please advise on this.




so yes , there is a P-1T, PIM coming, which is a one port smart serial PIM,  so for all the PIM enabled ISR1k's you can either have the LTE PIM or the P-1T PIM, but not both.  except in the 1109-4PLTE2P. this one SKU has 2 PIM's slots and can handle both PIM's.

Meena was correct in that it is geograhpically limited for the sale of the P-1T. It was designed for the LATAM/India markets with a large need of High speed serial as a WAN link requirement. 




Alpesh, thanks for attending our session.

The C1101-4P has a slot for pluggable modules and it can take either an LTE module or a P-1T module.

The P-1T module is for select regions only.It is not sold globally.Does this help?


Do security features including IDS/IPS run on the data plane CPU or control plane CPU on the ISR 4461? Are the 4 cores of the 4461 control plan comparable to the 4-cores on the earlier 44xx line or are they significantly faster?
