QoS
• Support for reclassifying frames based either on 802.1p
CoS value or default CoS value per port assigned by
network manager
• Four queues per egress port supported in hardware
• WRR queuing algorithm ensures low priority queues are
not starved
• Strict Priority Scheduling configuration ensures
time-sensitive applications such as voice always follow an
expedited path through the switch fabric
Ease-of-Use and Ease-of-Deployment
• Cisco CMS allows the network administrator to manage
up to 16 interconnected Catalyst 2950, 3550-12T, 3500
XL, 2900 XL, and 1900 switches through a single IP
address, using any standard Web browser regardless of the
location of the switches—that is, the switches do not have
to be physically located in the same wiring closet
• Full backward compatibility ensures that any Catalyst
3500 XL, Catalyst 2900 XL, or Catalyst 1900 switch can
be managed with a Catalyst 2950 using the Cisco CMS
• Cluster software upgrade feature allows the user to
automatically upgrade the system software on a group of
Catalyst 3550-12T, Catalyst 2950, Catalyst 3500 XL, and
Catalyst 2900 XL switches
• Autosensing on each port detects the speed of the attached
device and automatically configures the port for 10-, 100-
or 1000-Mbps operation, easing switch deployment in
mixed 10-, 100-, and 1000BaseT environments
• Autonegotiating on all ports automatically selects half- or
full-duplex transmission mode to optimize bandwidth
• Default configuration stored in Flash memory ensures the
switch is quickly connected to the network and can pass
traffic with minimal user intervention
Integrated Cisco IOS Switching Solution
• Bandwidth aggregation through Fast EtherChannel and
Gigabit EtherChannel technology enhances fault tolerance
and offers up to 4 Gbps of bandwidth between switches, 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 a user
interface and command set, which is common across all
Catalyst switches and Cisco routers
• Cisco Discovery Protocol (CDP) enables a CiscoWorks
network management station to automatically discover the
switch in a network topology
Superior Manageability
• Cisco CMS allows the network administrator to manage
up to 16 interconnected Catalyst 2950, 3550-12T, 3500
XL, 2900 XL, and 1900 switches through a single IP
address and any standard Web browser, regardless of the
location of the switches—that is, the switches do not have
to be physically located in the same wiring closet
• Switch clustering software upgrade allows network
administrators to upgrade the system software of up to 16
interconnected switches through the easy-to-use Cisco
CMS interface or a single CLI command
• Simple Network Management Protocol (SNMP),
and Telnet interface support delivers comprehensive
in-band management, and a CLI-based management
console provides detailed out-of-band management
• Manageable through CiscoWorks Windows network
management software on a per-port and per-switch basis
providing a common management interface for Cisco
routers, switches, and hubs
• Embedded Remote Monitoring (RMON) software agent
supports four RMON groups (History, Statistics, Alarms
and Events) for enhanced traffic management, monitoring,
and analysis
