This document describes how to differentiate between Trident-based and Typhoon-based line cards on a Cisco Aggregation Services Router (ASR) 9000 Series, and describes some additional types of line cards.
Differences between Trident-Based and Typhoon-Based Line Cards
The terms Trident-based and Typhoon-based 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 two types of ASR line cards.
Trident-Based Line Cards
The first generation of the Cisco ASR 9000 Series Ethernet line cards are often referred to as Trident-based line cards. The term comes from the Network Processors (NPs) that are used on these line cards.
You can easily identify Trident-based line cards, because there are only three types:
- L - Low Queue
- B - Base (Medium) Queue
- E - Extended (High) Queue
These line cards are Trident-based:
Typhoon-Based Line Cards
The second generation of the ASR 9000 Series Ethernet line cards are often referred to as Typhoon-based line cards. The term comes from the NPs that are used on these line cards.
These data sheets provide additional information about Typhoon-based line cards:
Similar to Trident-based line cards, you can easily identify Typhoon-based line cards, because there are only two types:
- SE - Services Edge Optimized
- TR - Packet Transport Optimized
These line cards are Typhoon-based:
Additional Types of Line Cards
This section describes other types of line cards for the ASR 9000.
This line card is based on the Client Provisioning Portal (CPP), and is neither Trident-based nor Typhoon-based. For more information, reference the Cisco ASR 9000 Series SPA Interface Processor 700 Cisco article.
This line card does not use NPs, and is neither Trident-based nor Typhoon-based. For additional information, reference the Cisco ASR 9000 Series Integrated Service Module Cisco article.
