ASR LC Typhoon
Table of Contents
Introduction
Typhoon is the second generation of Ethernet line cards for the ASR 9000 routers.
Typhoon
- Second generation of line cards.
- Two main types:
- SE - Service Edge Optimized
- TR - Packet Transport Optimized
Architecture
- The Typhoon line cards has similar components to the Trident LC, with the exception of the Bridge.
- PHY - stands for the physical layer of the interfaces. Performs functions such as:
- framing
- CRC
- speeds: 10GE, 40GE, 100GE
- form factors: SFP, SFP+, XFP, QSFP, CFP
- media/reach: T, SR, LR, ZR, LR4, SR10
- colors: gray, CWDM, DWDM, Tunable
- NP - stand for the Network Processor. The NP is used for forwarding and all feature such as:
- FIB, MAC, ACL, QoS, encap/decap, LPTS, all hardware features, buffer and i/f stats.
- L2 &L3 forwarding.
- control plane policing.
- FIA - stand for Fabric Interface ASIC.
- FIA is the interface to the backplane switching fabric.
- This is where the Virtual Output Queues (VOQs) reside.
- 2PQ + 1BE per egress 10G port. 2 priority queues. 1 best effort
- Different VOQ are generated for different egress port to prevent head of line blocking.
- EOBC - stand for Ethernet out-of-band channel.
- Connects the LC' CPU to the NP and FIA and the RP's CPU.
- This is an internal 1G switch used for control plane packets.
- Local Packet Transport Service (LPTS) runs over EOBC for internal communication to the the RP's CPU.
- LC CPU
- Program HW forwarding tables.
- Software switch packets.
- Netflow.

MOD - Modular Line Cards
- MOD are Modular Line Cards, which allow you to insert various port adapters called Modular Port Adapters (MPAs).
- They are still part of the Typhoon generation of line cards.
- There are two types of MODs: MOD80 and MOD160.
A9K-MOD80
- Modular Line Card with 80 Gbps and two network processing units.
- A9K-MOD80-SE
- A9K-MOD80-TR
- Mapping which port is assigned to which NP can be done with the command show controller np all location.
A9K-MOD160
- Modular Line Card with 160 Gbps and four network processing units.
- A9K-MOD160-SE
- A9K-MOD160-TR
- Modular Port Adapters - most of these fit into both MOD80s and MOD160 with few exceptions based on the bidirectional bandwidth calculation.
- A9K-MPA-20x1GE - 20-port 1 GE Ethernet Modular Port Adapter, requires SFP
- A9K-MPA-2x10GE - 2-port 10 GE Ethernet Modular Port Adapter, requires XFP
- A9K-MPA-4x10GE - 4-port 10 GE Ethernet Modular Port Adapter, requires XFP
- A9K-MPA-8x10GE - 8-port 10 GE Ethernet Modular Port Adapter, requires SFP+ (MOD160 only)
- A9K-MPA-1x40GE - 1-port 40 GE Ethernet Modular Port Adapter, requires QSFP
- A9K-MPA-2x40GE - 2-port 40 GE Ethernet Modular Port Adapter, requires QSFP (MOD160 only)
