Overview of the Cisco ASR 1000 Series Modular Ethernet Line Card

This chapter provides an introduction to modular interface processors (MIPs) and ethernet port adapters (EPAs). This chapter provides an overview of the release history, and feature and MIB support for the Cisco ASR 1000 Series Modular Ethernet Line Card (ASR1000-MIP100), 1-Port 100 Gigabit Ethernet EPA (EPA-1X100GEand 2-port 40 Gigabit Ethernet EPA (EPA-CPAK-2x40GE) on the Cisco ASR 1000 Series Routers.

This chapter includes the following sections:

Introduction to MIPs and EPAs

The ASR1000-MIP100 is a Modular Ethernet Line Card with a 100 Gbps connection to the backplane, for the ASR 1000 platform. However, it can have an interface bandwidth of up to 200 Gbps. The ASR1000-MIP100 provides higher I/O speeds, increased density, and interface flexibility to the ASR1000.

EPAs are small plug-in modules containing circuitry to provide optical or electrical network interfaces. The packet data between the EPA and MIP carrier card can support a 100Gbps full-duplex bandwidth. The data path supports operating at various pre-defined data rates and protocols.

Cisco ASR 1000 Series MIPs and EPAs use a carrier card and port adapter architecture that increases modularity, flexibility, and density across Cisco routers for network connectivity. This section describes the MIPs and EPAs, and provides some guidelines for their use.

Release History

Release

Modification

Cisco IOS XE Release 16.2.1

Added support for EPA-10X10GE

Cisco IOS XE Release 3.16.2S

Added support for EPA-CPAK-2X40GE

Cisco IOS XE Release 3.16.1S

First release. Support for the following hardwares were introduced on the Cisco ASR 1000 Series Routers:

  • Cisco ASR 1000 Series Modular Ethernet Line Card (ASR1000-MIP100)

  • 1-Port 100 Gigabit Ethernet EPA (EPA-1X100GE)

  • 10-Port 10 Gigabit Ethernet EPA (EPA-10X10GE)

Modular Interface Processors

The following list describes some of the general characteristics of a MIP:

  • A MIP is a carrier card that inserts into a Router slot like a line card. It provides no network connectivity on its own.
  • A MIP has two subslots, which are used to house one or more EPAs. The EPA provides interface ports for network connectivity.
  • During normal operation, the MIP should reside in the Router fully populated either with functional EPAs in all subslots, or with a blank filler plate (EPA-BLANK=) inserted in all empty subslots.
  • MIPs support online insertion and removal (OIR) with EPAs inserted in their subslots. EPAs also support OIR and can be inserted or removed independently from the MIP.

Note
Fully populate all slots and subslots with blank filler plates or functional EPAs for maximum efficiency of the cooling system.

Ethernet Port Adapters

The following list describes some of the general characteristics of an EPA:

  • An EPA is a modular type of port adapter that inserts into a subslot of a compatible MIP carrier card to provide network connectivity and increased interface port density. A MIP can hold one or more EPAs, depending on the MIP type.
  • EPA inserts into one of the MIP-EPA bay, with vertically aligned EPA subslots as shown in EPAs Inserted into the MIP Slots.
Figure 1. EPAs Inserted into the MIP Slots
  • Each EPA provides a certain number of connectors, or ports, that are the interfaces to one or more networks. These interfaces can be individually configured using the Cisco IOS command-line interface (CLI).
  • Either a blank filler plate or a functional EPA should reside in every subslot of a MIP during normal operation to maintain cooling integrity.
  • EPAs support online insertion and removal (OIR). They can be inserted or removed independently from the MIP. MIPs also support OIR with EPAs inserted in their subslots.

ASR1000-MIP100

The Cisco ASR 1000 Series Modular Ethernet Line Card (ASR1000-MIP100) is a modular-port ethernet line card for the Cisco ASR 1000 Series Routers, that is capable of 100 Gbps full-duplex traffic forwarded using a modular-port interface design. The ASR1000-MIP100 architecture is composed of a host carrier card, which accepts two EPAs. Each EPA can support either one 100 GE port or ten 10 GE ports. Overall, the ASR1000-MIP100 line card can support either two 100 GE ports, or twenty 10 GE ports, or one 100 GE port + ten 10 GE ports.

The ASR1000-MIP100 line card is supported on the Cisco ASR 1006-X Router, Cisco ASR 1009-X Router, and Cisco ASR 1013 Router with RP2 + ESP100, and RP2 + ESP200 combinations.

Modular Ethernet Line Card Architecture

This section provides an overview of the architecture of the Cisco ASR 1000 Series Modular Ethernet Line Card and describes the path of a packet in the ingress and egress directions. Some of these areas of architecture are referenced in the Modular Ethernet Line Card software and can be helpful to understand when performing troubleshooting tasks or interpreting some of the Modular Ethernet Line Card CLI and show command output.

Every incoming and outgoing packet on the Cisco ASR 1000 Series Modular Ethernet Line Card goes through the PHY SFP+ and CPAK optics module, the MAC, and a Layer 2 Filtering or Accounting Network Processor.

The Path of an Ingress Packet

The following steps describe the path of an ingress packet through the Cisco ASR 1000 Series Modular Ethernet Line Card:

  1. For a 100 GE port on the Cisco ASR 1000 Series Modular Ethernet Line Card, the CPAK optics receive incoming frames on a per-port basis from one of the optical fiber interface connectors.
  2. The MAC device receives the frame, strips the CRCs, and sends the packet to the Network Processor.
  3. The Network Processor takes the packet from the MAC devices, and qualifies the packet according to ethernet information by performing content-addressable memory (CAM) lookups based on Ethertype, port, VLAN and MAC address information, and determines whether a packet has to be dropped or forwarded to the QFP.

The Path of an Egress Packet

The following steps describe the path of an egress packet through the Cisco ASR 1000 Series Modular Ethernet Line Card:

  1. The packet is sent to the Network Processor from QFP. The packets are received with Layer 2 and Layer 3 headers in addition to the packet data.
  2. The Network Processor uses port number, destination MAC address, destination address type, and VLAN ID to perform CAM lookups. The Network Processor forwards the packet to the MAC device.
  3. For the Cisco ASR 1000 Series Modular Ethernet Line Card, the MAC device forwards the packets to the PHY laser-optic interface after adding CRCs, and the PHY transmits the packet.
