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.

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.  
Restrictions  
Supports only 100BASE SFPs and 1000BASE SFPs under two speed configurations:  
100 Mbps speed for 100BASE SFPs

Command or Action  
Purpose  
Step 4  
Step 5  
Step 6  
interface type slot/subslot/port number  
Selects an interface to configure.  
Example:  
Router(config)# interface ethernet 0/3/0  
media-type sfp  
Changes media type to SFP.  
Example:  
Router(config-if)# media-type sfp  
speed value  
Configures the speed of the interface.  
Note  
For 100BASE SFPs, configure the  
speed to 100 Mbps only. Similarly,  
for 1000BASE SFPs, configure  
the speed to 1000 Mbps only.  
Example:  
Router(config-if)# speed 100  
Step 7  
Step 8  
Step 9  
shutdown  
Disables the interface, changing its state  
from administratively UP to  
administratively DOWN.  
Example:  
Router(config-if)# shutdown  
no shutdown  
Enables the interface, changing its state  
from administratively DOWN to  
administratively UP.  
Example:  
Router(config-if)# no shutdown  
exit  
Exits the configuration mode and returns  
the global configuration mode.  
Example:  
Router(config-if)# exit  
Router(config)#  
Examples  
This example shows how to configure a third-party SFP on a Cisco ISR G2 Series Router:  
Router# configure terminal  
Router(config-if)# service unsupported-transceiver  
Router(config)# interface ethernet 0/3/0  
Router(config-if)# media-type sfp  
Router(config-if)# speed 100  
Router(config-if)# shutdown  
Router(config-if)# no shutdown  
Router(config-if)# exit  
Router(config)# exit
