WIC-4ESW Card
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
Caution
connect the 4-port 10/100BASE-TX Ethernet switch interface card (WIC-4ESW) only to intra-building
or non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be
grounded at both ends.
The show vtp status command shows the maximum number of VLANs supported by the router.
Note
Although the router supports more VLANs, the WIC-4ESW interface card supports a maximum of 16
VLANs.
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.

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.)
