Catalyst 2924M XL 10/100 Autosensing Fast Ethernet Switch |
|
The Cisco CatalystR 2924M XL 10/100 autosensing Fast Ethernet switch
combines outstanding performance, ease of use, and integrated Cisco IOSR
software from the leader in networking. The Catalyst 2924M XL is a flexible, scalable, and
affordable solution, ideal for aggregating Ethernet and Fast Ethernet workgroups and
delivering dedicated 10- or 100-Mbps connectivity for individual users and servers.
The Catalyst 2924M XL switch, a member of the Catalyst 2900
series XL family, contains 24 10BaseT/100Base TX ports and two versatile module slots to
provide unmatched expansion capabilities and high-speed connectivity. The modular design
allows users to easily add 10BaseT/100BaseT and 100BaseFX ports to increase port density
and deliver high-speed uplinks. The advanced Cisco architecture incorporates a switch
fabric of 3.2 Gbps and a forwarding rate of 3.0 million packets per second (pps) to
deliver wire-speed performance across all ports.
The Catalyst 2924M XL switch is an integral component of the
complete line of Cisco end-to-end LAN solutions. Integrated Cisco IOS software provides
superior functionality for network management, bandwidth aggregation, networked multimedia
and virtual LAN (VLAN) support. Available in Standard and Enterprise editions, the
Catalyst 2924M XL switch is upgradable via software, so your investment is protected if
your network grows or changes.

The Cisco Catalyst 2924M XL Standard Edition switch includes
several exceptional features to increase network performance for users. Fast EtherChannelR
technology offers up to 800 Mbps of high-performance bandwidth between other Catalyst 2900
XL switches, servers, and other key network stations. Cisco Group Management Protocol
(CGMP) enhances performance of multimedia applications and reduces network traffic by
allowing a switch to selectively and dynamically forward IP multicast traffic to targeted
end stations. Up to 64 port-based VLANs per switch allow data packets to be forwarded only
to stations within a specific VLAN, creating a virtual firewall between groups of ports on
the network. Cisco Visual Switch Manager (CVSM), a Web-browser interface, makes all
Catalyst 2900 XL switches exceptionally easy to use and manage. CVSM allows network
administrators to view and manage the switch from anywhere on the network through a
standard browser such as Microsoft Explorer or Netscape Navigator. Multilevel security on
the switch console prevents unauthorized users from gaining access and altering the switch
configuration. And autoconfiguration eases deployment by automatically configuring
multiple switches across a network from a single boot server. All Standard Edition
switches can be upgraded with the purchase of an optional Enterprise Edition Software
Upgrade Kit.
Enterprise Edition software includes all the features of the
Standard Edition, and adds enhanced end-to-end VLAN trunk support to your Catalyst 2924M
XL switch. VLAN trunks can be created from any port using either standards-based 802.1Q
protocols or the Cisco Inter-Switch Link (ISL) VLAN architecture. Each Catalyst 2924M XL
switch supports up to 64 VLANs to provide broadcast control, enhance network security, and
simplify moves, adds, and changes. An Enterprise Edition switch is the best choice for use
in a network with enterprise-wide VLAN trunks spanning multiple Cisco routers, chassis
switches, and access servers.
- Twenty-four 10BaseT/100BaseTX autosensing ports deliver Fast
Ethernet performance where it is needed most---to individual users, servers, and demanding
workgroups---while preserving legacy 10BaseT connectivity.
- Full-duplex operation on switched 100BaseT ports delivers up
to 200 Mbps of bandwidth to end stations, and servers, and between switches.
- A 3.2-Gbps switching fabric and 3.0 million pps forwarding
rate ensure wire-speed operation on all 10BaseT/100BaseTX ports.
- A 4-MB shared memory architecture ensures the highest possible
throughput by eliminating head-of-line blocking, minimizing packet loss, and reducing
congestion from multicast and broadcast traffic.
- Two high-speed expansion slots provide 1.6 Gbps of total
available bandwidth for additional 10BaseT/100BaseTX or 100BaseFX ports, as well as
Asynchronous Transfer Mode (ATM) and Gigabit Ethernet uplinks.
- Bandwidth aggregation through Fast EtherChannel technology
enhances fault tolerance and offers up to 800 Mbps of bandwidth among switches, routers,
and individual servers.
- Twelve EtherChannel bandwidth aggregation groups per switch
allow for a high-performance EtherChannel group for every two ports on a 24-port Catalyst
2900 XL switch.
- CGMP enables a switch to selectively and dynamically forward
routed IP multicast traffic to targeted multimedia end stations, reducing overall network
traffic.
- Configurable network port that supports unlimited Media Access
Control (MAC) addresses for backbone connectivity.
- Two versatile high-speed slots support a range of expansion
modules with different media configurations and port densities, allowing users the
flexibility to upgrade their networks and preserve their initial investment. All ports
support the Cisco ISL and standards-based 802.1Q VLAN trunking protocols.
- Four-port 10BaseT/100BaseTX, two-port 100BaseFX, and four-port
100BaseFX modules for the Catalyst 2924M XL switch allow customers to easily increase port
density, provide fiber connectivity over extended distances, and deliver higher-speed
uplinks through Fast EtherChannel bandwidth aggregation.
- CVSM software, a Web-based interface, provides network and
stack views of a group of Catalyst 2900 XL switches from any node on the Internet with a
Web browser.
- Autosensing on each port detects the speed of the attached
device and automatically configures the port for 10- or 100-Mbps operation, easing the
deployment of the switch in mixed 10BaseT and 100BaseT environments.
- Autonegotiation on all 10/100 ports automatically selects
half- or full-duplex transmission mode to optimize bandwidth.
- Default configuration stored in Flash memory ensures that the
switch can be connected to the network and pass traffic with minimal user intervention,
and preserves configuration in case of power outages.
- CGMP Fast Leave software allows end stations to quickly exit
from a multicast session, reducing superfluous traffic on the network.
- Bandwidth aggregation through Fast EtherChannel technology
enhances fault tolerance and offers up to 800 Mbps of bandwidth between switches, and to
routers and individual servers.
- Per-port broadcast storm control prevents faulty end stations
from degrading overall systems performance with broadcast storms.
- Command Line Interface (CLI) support provides common user
interface and a command set with Catalyst 5000/5500 series and 8500 series switches and
all Cisco routers.
- Simple Network Management Protocol (SNMP) and Telnet interface
support delivers comprehensive in-band management, and the Cisco IOS CLI-based management
console provides detailed out-of-band management.
- CVSM, a built-in HTTP server, provides ease-of-use Web-based
management interface through a standard browser such as Netscape Navigator or Microsoft
Explorer.
- The switch is manageable through CiscoWorks Windows and
CiscoWorks 2000 network management software on a per-port and per-switch basis, providing
a common management interface for Cisco routers, switches, and hubs.
- Cisco Discovery Protocol (CDP) enables a CiscoWorks network
management station to automatically discover the switch in a network topology.
- Embedded Remote Monitoring (RMON) software agent supports four
RMON groups (History, Statistics, Alarms, and Events) for enhanced traffic management,
monitoring, and analysis.
- Supports all nine RMON groups through use of a Switched Port
Analyzer (SPAN) port, which permits high-performance traffic monitoring of a single port,
a group of ports, or the entire switch from a single network analyzer or RMON probe.
- Autoconfiguration eases deployment of switches in the network
by automatically configuring multiple switches across a network via a boot server.
- Trivial File Transfer Protocol (TFTP) reduces the cost of
administering software upgrades by enabling downloads from a centralized location.
- Each port includes a multifunction LED for port status,
half-duplex/full-duplex, and 10BaseT/100BaseT indications as well as switch-level status
LEDs for system, module status, redundant power supply (RPS), and bandwidth utilization,
which provides a comprehensive and convenient visual management system.
- IEEE 802.1d Spanning-Tree Protocol support for redundant
backbone connections and loop-free networks simplifies network configuration and improves
fault tolerance.
- MAC-based port level security prevents unauthorized stations
from accessing a switch.
- User-selectable address learning mode simplifies configuration
and enhances security.
