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:
Similar to Typhoon-based line cards, each Tomahawk-based 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 Tomahawk-based:
Note: Tomahawk-based line card part numbers that begin A99-X are compatible with the Cisco ASR 9904, ASR 9910, ASR 9912, and ASR 9922 chassis. They are not compatible with the Cisco ASR 9006 and ASR 9010 Routers.
Note: A99-12X100GE line cards are designed for transport integration in high-density 100G environments and deliver line-rate packet performance for IP and Multiprotocol Label Switching (MPLS) transport. There is not an SE or TR variant of this card. This line card has it's own unique features and restrictions different from other Tomahawk-based line cards.
Additional Types of Line Cards
This section describes other types of line cards for the ASR 9000.
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.
