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
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.
The SFP slot supports Cisco certified copper or optical SFPs. For a list of supported SFPs, see
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.

Configuring Loopback
DETAILED STEPS
Command or Action
Purpose
Enables privileged EXEC mode.
Enter your password if prompted.
Step 1
enable
•
Example:
Router> enable
Step 2
Step 3
Enters global configuration mode.
configure terminal
Example:
Router# configure terminal
Enters the configuration mode for
Ethernet transport on the EHWIC
interface on the router.
interface type slot/subslot/port number
Example:
Router(config)# interface ethernet
0/3/0
Step 4
Sets the IP address and subnet mask for
the interface.
ip address ip-address mask
Example:
Router(config-if)# ip address
192.168.12.2 255.255.255.0
Step 5
Step 6
Step 7
Disables the interface, changing its state
from administratively up to
administratively down.
shutdown
Example:
Router(config-if)# shutdown
Enables the interface, changing its state
from administratively down to
administratively up.
no shutdown
Example:
Router(config-if)# no shutdown
Exits configuration mode and returns to
global configuration mode.
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.
