What is the difference between Service Edge Optimized line cards and Packet Transport line cards in the ASR 9000

Hi Folks,

What is the deep dive difference between the service edge optimized cards and the packet transport line cards in the ASR 9000?

I know that QoS is the difference in general, for example, the service edge optimized has advanced QoS features while the Packet Transport line cards has basic QoS features but I want to know some more details please.

Thanks

What is the difference between Service Edge Optimized line cards

There are four main deiffences (unfortunately don't have a reference link).

L3 Interfaces:

TR: 8k/LC, SE: 20k/LC

L2 Interfaces:

TR: 16k/LC, SE: 64k/LC

QoS:

TR: only 8 Queues per port, 8k policers per Network Processor

SE: 256k Queues per port, 256k policers per NP

ACL:

TR: 24k ACE

SE: 96k ACE

Number of FIB/mFIB/MAC etries, L3 VRFs, PWs available per TR/SE linecard are the same.

That is indeed correct, the TR cards have limit L2 interface support and limited number of queues and policers.

the SE (service edge) cards have a large scale of queues and policers nad l2 interfaces which you want to use for edge facing applications (and is must have for BNG).

Take the cisco live presentation ID 2904 which details all the differences out even more if you like more info on this topic.
