the switch line cards. The 48 ports can burst to Gigabit Ethernet
line rate and share 12 Gbps of capacity (6 Gbps full-duplex) into
the switching fabric. The amount of oversubscription can be
controlled by varying the number of ports used at 1000 Mbps. All
ports can utilize Gigabit EtherChannel or IEEE 802.3ad for
high-speed interconnection applications. All ports use the standard
IEEE 802.1x flow control (PAUSE frame) mechanism to control
Gigabit Ethernet host traffic.
24-Port 10/100/1000BASE-T Line Card
(WS-X4424-GB-RJ45)
The Cisco Catalyst 4000/4500 Series 24-port 10/100/1000BASE-T
line card provides 24 RJ-45 ports with triple speed auto-sensing
and auto-negotiating technology, enabling all ports to be used at
10 Mbps, 100 Mbps, or 1000 Mbps up to 100 meters over
Category 5 copper cabling. This module provides wiring closet
investment protection by allowing Fast Ethernet desktops today to
migrate to Gigabit Ethernet in the future without replacing the
switch line cards. The 24 ports can burst to Gigabit Ethernet line
rate and share 12 Gbps of capacity (6 Gbps full-duplex) into the
switching fabric. The amount of oversubscription can be
controlled by varying the number of ports used at 1000 Mbps. All
ports can utilize Gigabit EtherChannel or IEEE 802.3ad for
high-speed interconnection applications. All ports use the standard
IEEE 802.1x flow control (PAUSE frame) mechanism to control
Gigabit Ethernet host traffic.
Gigabit-over-Fiber GBIC-Enabled Modules
The Cisco Catalyst 4000/4500 Series offers a rich variety of
GBIC-enabled gigabit-over-fiber solutions for high-performance
Gigabit Ethernet uplinks and server farm connectivity. The three
GBIC-enabled gigabit line card options for the Cisco Catalyst
4000 Series, shown below, include the 6-port 1000BASE-X
(WS-X4306-GB), the 18-port 1000BASE-X (WS-X4418-GB), and
the 48-port 1000-BASE-LX module.

Six-Port GBIC-Enabled Gigabit Ethernet Line Card
(WS-X4306-GB)
The Cisco Catalyst 4000/4500 Series six-port Gigabit Ethernet line
card provides six ports of dedicated 1000BASE-X Gigabit
Ethernet uplinks for high-speed backbone, switch-to-switch
applications or small server-farm applications. It uses the versatile
GBIC technology so intrabuilding multimode connections can be
intermixed with long-distance, campus, single-mode connections.
All ports can utilize Gigabit EtherChannel or IEEE 802.3ad for
high-speed interconnection applications.
18-Port GBIC-Enabled Gigabit Ethernet Line Card
(WS-X4418-GB)
The Cisco Catalyst 4000/4500 Series 18-port Gigabit Ethernet line
card provides two ports of dedicated 1000BASE-X GBIC-based
Gigabit Ethernet uplinks, as well as up to 16 GBIC-based ports for
high-performance Gigabit Ethernet server connectivity. The 16
server ports can burst to Gigabit Ethernet line rate and share 8
Gbps of capacity (4 Gbps full-duplex) into the switching fabric.
Because all ports use GBICs, the amount of oversubscription can
be controlled by varying the number of GBICs used. All ports can
utilize Gigabit EtherChannel or IEEE 802.3ad for high-speed
interconnection applications. The server ports use the standard
IEEE 802.1x flow control (PAUSE frame) mechanism to control
Gigabit Ethernet host traffic.
