This document describes how to differentiate between Trident-based, Typhoon-based, and Tomahawk-based line cards on a Cisco Aggregation Services Router (ASR) 9000 Series, and describes some additional types of line cards.
Differences between Trident-Based, Typhoon-Based, and Tomahawk-Based Line Cards
The terms Trident-based, Typhoon-based, and Tomahawk-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 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 (or Ethernet) 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 (or Enhanced Ethernet) 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:
This line card includes a Service Infrastructure Module with Typhoon-based NPs, Crossbar Fabric, and Fabric Interface ASIC (FIA) components that are also used on the Typhoon-based line cards. For additional information, reference the Cisco ASR 9000 Series Virtualized Services Module Cisco article.
