12, 22, and 24 autosensing switched 10BaseT/100BaseTX ports

Delivers performance where required, such as server farms, power
workgroups, and individual users

Preserves investment in legacy 10BaseT equipment, such as NIC cards,
hubs, and switches

Four-port 10BaseT/100BaseTX switch module (Catalyst
2912MF XL and 2924M XL only)

Provides a cost-effective means to increase the port density of the
Catalyst 2912MF XL and 2924M XL

Two switched 100BaseFX ports (Catalyst 2924C XL only) and 12
switched 100BaseFX ports (Catalyst 2912MF XL only)

Delivers high-speed connectivity between Catalyst 2912MF XL,
Catalyst2924C XL, and another device over an extended distance of up to 2
kilometers

2-port and 4-port 100BaseFX switch modules

Cost-effective means to deliver connectivity between a Catalyst 2912MF
XL or 2924M XL and another device over an extended distance of up to 2
kilometers

Two versatile module slots accommodate future network
expansion plans

Provides a flexible means to enhance the base switch offering without the
need for a forklift upgrade

Future support for Gigabit Ethernet (1000BaseX) and OC-3 ATM

Up to 64 port-based VLANs per Catalyst 2900 XL switch enable
groups of devices on a LAN to communicate as if they are on
the same wire, even if they are on different LAN segments

Improve performance and scalability by evaluating network traffic
patterns and assigning users to VLANs associated with appropriate
network resources and bandwidth

Reduce administrative costs and simplify network moves, adds, and
changes

Enable better management and control of broadcast and multicast traffic

Improve network security by establishing separate VLAN groups for
high-security users and relocating workgroup servers into secured,
centralized areas

Support for standards-based IEEE 802.1Q and Cisco ISL VLAN
trunking protocols (Enterprise Editions only)

Enables deployment of up to 64 enterprise-wide VLAN trunks per 2900 XL
switch, spanning multiple routers, chassis switches, and access servers

Detects the speed of the attached device and automatically
configures the port for 10 or 100 Mbps

Eases deployment of the switch in mixed 10BaseT and 100BaseT
environments

Automatically selects half- or full-duplex transmission mode

Optimizes bandwidth utilization

3.2-Gbps switching fabric and 3.0 million packets-per-second
forwarding rate

Meets the demands of the most intensive network applications

Ensures full wire-speed operation for each 10BaseT/100BaseTX port

Full-duplex operation on switched 100BaseT ports

Delivers up to 200 Mbps of bandwidth to end stations and servers, and
between switches

4-MB shared memory architecture

Ensures highest possible throughput by eliminating head-of-line blocking,
minimizing packet loss, and reducing congestion from multicast and
broadcast traffic

Bandwidth aggregation through Fast EtherChannel technology

Delivers up to 800-Mbps connectivity between switches, and to routers
and individual servers

Enhances fault tolerance

Per-port broadcast storm control

Prevents faulty end stations from degrading overall system performance
with broadcast storms

Cisco Group Management Protocol (CGMP)

Enables the switch to selectively forward routed IP multicast traffic to
targeted multimedia end stations, reducing overall network traffic
