Introduction
This document describes how to differentiate between different generations of Cisco Aggregation Services Router (ASR) 9000 Series.
Differences Between Line Card Generations
The terms Ethernet, Carrier Ethernet, High Density Ethernet 3rd Generation, High Density Ethernet 4th Generation, High Density Ethernet 5th Generation are often used in discussions about features, route-scale, architecture, and general troubleshooting of packet flows on an ASR 9000 Series router. This section describes the differences between these types of ASR line cards.

Note: The Cisco ASR 9000 Series Ethernet Line Cards data sheet provides a list of the first generation Ethernet line cards.
You can easily identify Ethernet line cards, because there are only three types:
- L - Low Queue
- B - Base (Medium) Queue
- E - Extended (High) Queue
These line cards are Ethernet line cards:

Carrier Ethernet Line Cards are available in Service Edge Optimized and Packet Transport Optimized variants.
- Service Edge Optimized line cards are designed for deployments that require enhanced quality of service (QoS).

- A9K-4T16GE-TR
Note: The ASR-9001 and ASR-9001-S have Carrier Ethernet line cards built into the stand-alone chassis. Reference the Cisco ASR 9001 Router Data Sheet and Cisco ASR 9001-S Router Data Sheet articles for more details.
High Density Ethernet Line Cards (3rd Generation)
The third generation of the ASR 9000 Series High Density Ethernet line cards all share the same type of Network Processors (NPs).
These data sheets provide additional information about High Density 3rd generation line cards:
Similar to 2nd generation line cards, each 3rd generation line card is available as either a Service Edge Optimized (enhanced QoS) or Packet Transport Optimized (basic QoS) line card.
- SE - Services Edge Optimized
- TR - Packet Transport Optimized
The 4-Port and 8-Port 100 Gigabit Ethernet line card is available in two variants that support either LAN/WAN/OTN unified PHY CPAK ports or LAN PHY-only CPAK ports.
These line cards are High Density 3rd Generation:
- A9K-8X100G-LB-SE

Additional Types of Line Cards
This section describes other types of line cards for the ASR 9000.
SPA Interface Processor Line Card (A9K-SIP-700)
This line card is based on the Cisco Packet Processor (CPP), and is not based on the type of Network Processors (NPs) used by the other generations of line cards. For more information, reference the Cisco ASR 9000 Series SPA Interface Processor 700 Cisco article.
Service Module Line Cards
Integrated Service Module (A9K-ISM-100)
This line card does not use Network Processors (NPs) used by the other generations of line cards. For additional information, reference the Cisco ASR 9000 Series Integrated Service Module Cisco article.
