Configuring Gigabit Ethernet Enhanced
High-Speed WAN Interface Cards
First Published: March 15, 2011
This document describes how to configure the Cisco Gigabit Ethernet enhanced high-speed WAN
interface card (EHWIC). The EHWIC 1 GE-SFP-CU can be installed on the Cisco Integrated Services
Routers Generation 2 (ISR G2) family platforms and has a dual-purpose uplink (DPU) that can run in
small-form-factor pluggable (SFP) or copper mode. It supports the following features:
• Digital Optical Monitoring (DOM)
• Support for T1/E1 and T3/E3 SFPs
• Support for the Ethernet passive optical network (EPON) SFP
EHWIC 1 GE-SFP-CU is the SKU for the single port EHWIC.
For a list of SFPs supported on the EHWIC 1 GE-SFP-CU, see Connecting Gigabit Ethernet High-Speed
WAN Interface Cards document at the following URL:

Overview of the EHWIC 1 GE-SFP-CU
The Cisco Gigabit Ethernet WAN EHWIC (EHWIC 1 GE-SFP-CU) is an enhanced high-speed interface
card providing copper and optical Gigabit Ethernet ports and connectivity of T1/E1 and T3/E3 over
optical for Cisco ISRs.
The EHWIC 1 GE-SFP-CU provides copper and optical Gigabit Ethernet connectivity through a
dual-purpose uplink.
Note The EHWIC 1GE SFP CU provides maximum 800 Mbps unidirectional and 1600 Mbps bidirectional
Ethernet throughput, but the actual throughput is limited by the platform.
Overview of the EHWIC 1 GE-SFP-CU
The SFP slot supports Cisco certified copper or optical SFPs. For a list of supported SFPs, see
Connecting Gigabit Ethernet High-Speed WAN Interface Cards.
The EHWIC 1GE SFP CU is a true routed port card. IP addresses can be directly configured on the
EHWIC interface unlike SVI configurations in which the port is configured for VLAN trunking.
The Mean Time Between Failover(MTBF) for this module is 3162805 hours.

Step 7
shutdown
Example:
Router(config-if)# shutdown
no shutdown
Example:
Router(config-if)# no shutdown
exit
Example:
Router(config-if)# exit
Router(config)#
Configuring Loopback
Use the loopback command in interface configuration mode to configure loopback. The
EHWIC 1 GE-SFP-CU supports MAC layer loopback and driver type loopback. The MAC loopback is
used to detect MAC failure. The driver loopback is used to detect transceiver failure. Use the show
interface to see the loopback mode and check if the hardware is functional.
Disables the interface, changing its state
from administratively up to
administratively down.
Enables the interface, changing its state
from administratively down to
administratively up.
Exits configuration mode and returns to
global configuration mode.

Configuring SFPs
The SFP driver is responsible for periodically monitoring the SFP for any change in the SFP status or
SFP type. Once an SFP module is detected, the SFP driver reads the contents of the SFP EEPROM cookie
and validates the SFP. When a valid SFP is detected, the SFP speed and SFP duplex restrictions are
applied on the PHY chip and reflected in Cisco CLI.
Configuring Third-Party SFPs
Small Form-Factor Pluggables (SFPs) that are not Cisco certified are called third-party SFPs. Cisco
approved means the SFPs have undergone rigorous testing with Cisco products and the SFPs are
guaranteed to have 100% compatibility.
Third-party SFPs are manufactured by companies that are not on the Cisco-approved Vendor List (AVL).
Currently, Cisco ISR G2 routers support only Cisco-approved SFPs. From Release 15.3(2)T, Cisco ISR
G2 routers recognize third-party SFPs.
Note Cisco does not provide any kind of support for the third-party SFPs because they are not validated by
Cisco.
