(GBIC). 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 Cisco Catalyst 2912MF XL Fast Ethernet

Flexible Stacking with the GigaStack GBIC
Gigabit Ethernet-enabled Catalyst 2900 Series XL
switches and Catalyst 3500 Series XL can be stacked
using the low-cost two-port Cisco GigaStack GBIC,
which offers a range of highly flexible stacking and
performance options. Customers can deploy a 1-Gbps
independent stack backplane in a cascade configuration,
orscaleup to5-Gbpsof bandwidthina starconfiguration
using the Catalyst 3508G XL Gigabit Ethernet
aggregation switch. Network managers may use one or
both of the available GBIC ports on a Gigabit
Ethernet-enabledCatalyst2900SeriesXLswitchtocreate
high-speed uplinks to the network core, using standard
Gigabit Ethernet or Gigabit EtherChannel technology.
High resiliency can also be implemented by deploying
dual Gigabit Ethernet uplinks, a redundant GigaStack
loopback cable, Cisco Uplink Fast and Cross-stack
Uplink Fast technologies for high-speed uplink and stack
interconnection failover, and PVST+ (Per VLAN
Spanning Tree) for uplink load balancing.
Cisco Switch Clustering
Breakthrough Cisco Switch Clustering technology
enables up to 16 interconnected Catalyst 3500 XL,
2900 XL, and Catalyst 1900 switches, regardless of
geographic proximity, to form a single IP management
domain. Switch Clustering supports a broad range of
standards-based connectivity options and configurations
to deliver levels of performance that are scalable to meet
customer requirements. Switch Clustering connectivity
options for the Catalyst 2900 Series XL include Ethernet,
Fast Ethernet, Fast EtherChannel ports, low-cost
Cisco GigaStack GBIC, Gigabit Ethernet, and Gigabit
EtherChannelports. Becausethe technologyis notlimited
by proprietary stacking modules and stacking cables,
Cisco Switch Clustering expands the traditional stacking
domain beyond a single wiring closet and lets users mix
andmatch interconnectionsto meet specific management,
performance, and cost requirements.
A command switch, either a Catalyst 2900 XL or 3500
XL, provides the proxy and redirection services for single
IP address management for each cluster. All cluster
management commands are targeted to the command
switch IP address. For redundancy, a second switch can
be assigned an IP address, and the overall cluster can
then be managed using a single virtual IP address. If the
primary command switch fails, the backup or secondary
command switch seamlessly takes over the management
of the cluster while a user still accesses the cluster via the
virtual IP address.
Cisco Switch Clustering can be accessed via Cisco Cluster
Management Suite (CMS), a Web-based management
interface, which allows network administrators to
configure, monitor, and manage a switch from anywhere
on the network through a standard browser such as
Microsoft Internet Explorer or Netscape Navigator.
Networkadministrators simply pointtheir Web-browsers
to the IP address of the cluster Command switch and
access all management capabilities. The CMS interface
is launched from the switch itself and delivers simple,
cluster-wide, device-level management, including port
configuration, VLAN setup, network views, and port
monitoring—all from a single graphical interface.
Web-based management is an integral part of the Cisco
Switch Clustering architecture, allowing users to easily
configure and manage stacks and switch clusters, and
administer software upgrades across multiple switches.
Command switch and cluster management redundancy
are ensured via an automatic failover scheme in the rare
event of a command switch failure.

for 10 or 100 Mbps operation, easing the deployment
of the switch in mixed 10Base-T and 100Base-T
environments.

that the switch can be connected to the network and pass
traffic with minimal user intervention, and preserves the
configuration data in case of power outages.
Integrated Cisco IOS Switching Software
• CGMP Fast Leave software allows end stations to
quickly exit from a multicast session, reducing
superfluous traffic on the network.

network management station to automatically discover
the switch in a network topology.
• An embedded Remote Monitoring (RMON) software
agent supports four RMON groups (history, statistics,
alarms, and events) for enhanced traffic management,
monitoring, and analysis.
• Cisco IOS software 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.
