This document describes Cisco LAN interface cards and how to connect Cisco LAN interface cards to a network. It contains the following sections:
•

For an overview of Cisco interface cards used for Cisco access routers see the Cisco Interface Cards for Cisco Access Routers document.
WIC-4ESW Card
This section describes the 4-port 10/100BASE-TX Ethernet switch interface card (WIC-4ESW) and how to connect it to a network.
The following subsections are included:
•
•
•
•
The WIC-4ESW interface card is a Layer 2 Ethernet switch with Layer 3 routing capability. (Layer 3 routing is forwarded to the host, and is not actually performed at the switch.) The ports autosense the speed (10 Mbps or 100 Mbps) and duplex mode (full- or half-duplex) of the device to which it is connected and then operates at the same speed and in the same duplex mode.
Caution
Note
There are no new or modified commands for use with the WIC-4ESW interface card. All commands used with the switch are documented in the Cisco IOS command reference publications.
Figure 107 shows the WIC-4ESW interface card.

WIC-4ESW Interface Card LED
The LNK (physical layer link) LED is on when the Cisco IOS software recognizes the switch and the connection is up. The ACT (activity) LED indicates that data is being transmitted or received on the slot.
Additional information on the features of the card is provided in the 4-Port Ethernet Switch Configuration Notes for the Cisco 1700 Series Routers document.
WIC-4ESW Interface Card Port Numbering
Port numbers identify the interfaces on the modules and interface cards installed in the router. Modules and interface cards are identified by interface type, slot number, a forward slash (/), and the port number. For example, F0/0 denotes the first Fast Ethernet port of the interface card, installed in slot 0 of the router.
The first port on the WIC-4ESW is always identified as "1." For the Cisco 1721 router, the ports are referred to as FastEthernet1 to FastEthernet4, no matter in what slot the card is installed.
On the Cisco 1751 router and the Cisco 1760 router, the Fast Ethernet interfaces on WIC-4ESW are addressed as F<slot>/1 through F<slot>/4, depending in what slot the card is installed. (In this document, the ports will be referred to as F1 through F4.)
WIC-4ESW Interface Card Processor Requirements
The MPC 860 microprocessor (revision B5 or later) is required for using the Cisco WIC-4ESW card.
WIC-4ESW Interface Card Supported Standards
The WIC-4ESW interface card supports IEEE 802.3 Ethernet standards and 100BASE-T Category 3, 4, and 5 UTP cable distances up to 328 feet (100 meters).
The following standards are also supported:

WIC-1ENET Interface Card
This section describes how to connect the Cisco 1-port Ethernet interface card supporting 10BASE-T Ethernet (WIC-1ENET), and contains the following sections:
•
•
The 1-port Ethernet interface card provides the router with additional Ethernet interfaces that can use the functionality of the Cisco IOS software with any type of external broadband modem, such as a cable modem, or xDSL modem.
Figure 108 shows the WIC-1ENET interface card.

WIC-1ENET Interface Card LED
The LNK (physical layer link) LED is on when the Cisco IOS software recognizes the WIC-1ENET card and the connection is up. The FDX LED is on when the port is operating in full-duplex mode, and off when operating in half-duplex mode. Additionally, the Activity LED on the front of the router indicates that data is being transmitted or received on the slot.
WIC-1ENET Requirements
This section describes the requirements and supported standards for the WIC-1ENET card.
WIC-1ENET Memory Requirements
To run Cisco IOS images that support the WIC-1ENET card, the router must have a minimum amount of Flash memory and dynamic RAM (DRAM). For details on the memory requirements for each image, refer to Release Notes for the Cisco 1700 Series Routers for Cisco IOS Release 12.2(4)T.
WIC-1ENET Software Requirements
The WIC-1ENET card requires Cisco IOS Release 12.2(2)XJ or later if the card is installed in any WIC slot other than slot 0 or if more than one card is installed.
The card can be used with Cisco IOS Release 12.2(4)T, but the card must be installed in slot 0 and only one WIC-1ENET card can be installed in the router.
WIC-1ENET Interface Card Port Numbering
Port numbers identify the interfaces on the modules and interface cards installed in the router. Port numbers begin at 0 for each slot, and continue from right to left. Modules and interface cards are identified by interface type, slot number, a forward slash (/), and the port number. For example, E0/0 denotes the first Ethernet port of the interface card installed in slot 0 of the router.
On the Ethernet interface on the Cisco 1720 router is E0. The interface on the WIC-1ENET is addressed as E1.
On the Cisco 1750 router, the Ethernet interface on the router is E0/0. The interface on the WIC-1ENET is addressed as E<slot>/1.
WIC-1ENET Interface Card Router Processor Requirements
The MPC 860 microprocessor (revision B5 or later) in the Cisco 1700 series router is required for using the WIC-1ENET card.
The processor version information is displayed at bootup. You can also verify the processor revision by entering the show version command at the Cisco IOS command-line interface
Router#prompt.WIC-1ENET Supported Standards
The IEEE 802.3 Ethernet standards and 10BASE-T Category 3, 4, and 5 UTP cable distances up to 328 feet (100 meters) are supported.
WIC-1ENET Full-Duplex and Half-Duplex
The WIC-1ENET is set to half-duplex mode by default, and it does not autosense the mode of another device attached to the port. If you set the card to full-duplex operation, you must also set the device to which the port is attached to full-duplex mode.
Use the full-duplex command to put the Ethernet interface into full-duplex operation. The interface can be put into half-duplex mode by entering the no full-duplex command.
You can also use the half-duplex command to put the Ethernet interface into half-duplex operation, the default state of the Ethernet interface.
To verify the interface state, enter a show interface command as follows:
1750#show interface Ethernet 0Ethernet0 is up, line protocol is upHardware is PQUICC Ethernet, address is 0001.64ff.ef6a (bia 0001.64ff.ef6a)MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,reliability 255/255, txload 1/255, rxload 1/255Encapsulation ARPA, loopback not setKeepalive set (10 sec)Half-duplex, 10BaseT....Supported Platforms
For a list of the platforms supported by a Cisco interface card refer to Platform Support for Cisco Interface Cards.
