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:
http://www.cisco.com/en/US/docs/routers/access/interfaces/ic/hardware/installation/guide/EHWIC_1_
GE_SFP_CU.html.

Prerequisites for the EHWIC 1 GE-SFP-CU
This section lists the prerequisites for configuring the EHWIC 1 GE-SFP-CU.
•Ensure that you have the appropriate Cisco access router to serve as the host router. The following
Cisco access routers support EHWIC 1 GE-SFP-CU.
– Cisco 1921 ISR
– Cisco 1941 ISR
– Cisco 2901 ISR
– Cisco 2911 ISR
– Cisco 2921 ISR
– Cisco 2951 ISR
– Cisco 3925 ISR
– Cisco 3925E ISR
– Cisco 3945 ISR
– Cisco 3945E ISR
•Use the show version command to ensure that the router is running Cisco IOS Release 15.1(4)M or
later.
Note When minimum release requirements are met, you can change images on the router without affecting
performance. Install the EHWIC 1 GE-SFP-CU on the router, using the directions provided in Installing
Cisco Interface Cards in Cisco Access Routers and Cisco Network Modules and Interface Cards
Regulatory Compliance and Safety Information.
Restrictions for the EHWIC 1 GE-SFP-CU
Online insertion and removal is not supported for EHWIC 1 GE-SFP-CU.

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
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.

Configuring Loopback
DETAILED STEPS
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.
Command or Action Purpose
Step 1 enable
Example:
Router> enable
Enables privileged EXEC mode.
•Enter your password if prompted.
Step 2 configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3 interface type slot/subslot/port number
Example:
Router(config)# interface ethernet
0/3/0
Enters the configuration mode for
Ethernet transport on the EHWIC
interface on the router.
Step 4 ip address ip-address mask
Example:
Router(config-if)# ip address
192.168.12.2 255.255.255.0
Sets the IP address and subnet mask for
the interface.
Step 5 shutdown
Example:
Router(config-if)# shutdown
Disables the interface, changing its state
from administratively up to
administratively down.
Step 6 no shutdown
Example:
Router(config-if)# no shutdown
Enables the interface, changing its state
from administratively down to
administratively up.
Step 7 exit
Example:
Router(config-if)# exit
Router(config)#
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.
Restrictions
•Supports only 100BASE SFPs and 1000BASE SFPs under two speed configurations:
•100 Mbps speed for 100BASE SFPs

SUMMARY STEPS
1. enable
2. configure terminal
3. service unsupported-transceiver
4. interface type slot/subslot/port number
5. media-type sfp
6. speed value
7. shutdown
8. no shutdown

DETAILED STEPS
Command or Action Purpose
Step 1 enable
Example:
Router> enable
Enables the privileged EXEC mode.
Enter your password if prompted.
Step 2 configure terminal
Example:
Router# configure terminal
Enters the global configuration mode.
Step 3 service unsupported-transceiver
Example:
Router(config)# service
unsupported-transceiver
Enables third-party SFP support.

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
Additional References
The following sections provide references related to EHWIC 1 GE-SFP-CU.
Step 4 interface type slot/subslot/port number
Example:
Router(config)# interface ethernet 0/3/0
Selects an interface to configure.
Step 5 media-type sfp
Example:
Router(config-if)# media-type sfp
Changes media type to SFP.
Step 6 speed value
Example:
Router(config-if)# speed 100
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.
Step 7 shutdown
Example:
Router(config-if)# shutdown
Disables the interface, changing its state
from administratively UP to
administratively DOWN.
Step 8 no shutdown
Example:
Router(config-if)# no shutdown
Enables the interface, changing its state
from administratively DOWN to
administratively UP.
Step 9 exit
Example:
Router(config-if)# exit
Router(config)#
Exits the configuration mode and returns
the global configuration mode.
