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

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.

Feature History

1	SFP EN LED, which shows connectivity to the router.	2	ACT LED, which shows TX/RX activity.
3	LNK LED, which shows link status.	4	SPD LED, which shows transmission speed.

LEDs

Table 1 lists the LEDs and describes their functionality and different states. The LEDs provide a visual indication of your available services.

Table 1

LED	Color	Description
SFP EN	Off	Not present.
	Green	Present and enabled.
	Amber	Present with failure.
ACT	Solid or blinking green	Blinks proportional to valid Ethernet traffic.
	Off	No packet transfers are occurring.
LNK	Green	Solid green indicates the Ethernet port has a link partner.
SPD	Off	No link.
	Green	Note Blink indicates port speed.
	blinking	1 blink before pause—10 Mbps link speed. 2 blinks before pause—100 Mbps link speed. 3 blinks before pause—1000 Mbps link speed.

Configuring the EHWIC 1 GE-SFP-CU

This section describes how to configure your EHWIC 1 GE-SFP-CU.

SUMMARY STEPS

1. enable

2. configure terminal

3. interface type slot/subslot/port number

4. ip address ip-address mask

5. shutdown

6. no shutdown

7. exit

DETAILED STEPS

	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 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

•1000 Mbps speed for 1000BASE SFPs

•Only the following routers and modules support third-party SFPs:

•Cisco 2921 Integrated Services Router

•Cisco 2951 Integrated Services Router

•Cisco 3900 Integrated Services Router

•Cisco 3900E Series Integrated Services Routers

•Cisco 892-F Gigabit Ethernet Security Router

•Cisco 898-EA Gigabit Ethernet Security Router

•EHWIC-1GE-SFP

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

9. exit

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.
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.

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
