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:
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.

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.
The following is a list of some of the significant hardware and software features supported by the Cisco ASR 1000 Series Modular Ethernet Line Card (ASR1000-MIP100) on the Cisco ASR 1000 Series Routers using Cisco IOS XE Release 3.16S:
Feature Name |
Description |
---|---|
VLAN Unlimited |
The hw-module subslot x/y ethernet vlan unlimited configuration command increases the ethernet card default to system limit. This enables support for configuring higher than the default EPA/SPA limit. |
Fast Re-route (FRR) |
Although this feature can be configured on Cisco IOS XE Release 3.16S, the FRR switchover time can be more than 50 ms. |
Configurable PLIM QoS |
|
Configurable pause frame thresholds |
Configuration of threshold percentages at which the pause frames should be generated using the plim qos input queue queue # pause percent command is not supported. |

The EPA-CPAK-2x40GE is supported in IOS XE 3.16.2 and later 3.16.x releases. It is not supported in IOS XE 3.17.x releases. |
The 1-Port 100 Gigabit Ethernet EPA (EPA-1X100GE) uses a CPAK module to provide network connectivity, The EPA-CPAK-2x40GE uses a CPAK module and a 2x40 GE breakout cable to provide network connectivity. The 10-Port 10 Gigabit Ethernet EPA (EPA-10X10GE) uses small form-factor pluggable (SFP+) optical transceivers to provide network connectivity.
Cisco qualifies the SFP+ and CPAK modules that can be used with EPAs as shown in the following table.

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