Cisco Catalyst 3550 Series
Intelligent Ethernet Switches for Metro Access
Product Overview
The Cisco Catalyst
®
3550 Series Intelligent
Ethernet switches is a line of powerful,
fixed-configurationmultilayerswitchesthat
extendintelligenceto themetroaccessedge,
enabling service breadth, availability,
security,andmanageability.Keycomponents
of the Cisco Metro Ethernet Switching
portfolio,theseswitches areidealforservice
providers looking to deliver profitable
Ethernet services while minimizing total
cost of ownership. With a range of Fast
Ethernet, Gigabit Ethernet, DC power, and
fiber configurations, the Cisco Catalyst
3550 Series is the ideal metro access switch
for enterprise and small and medium-sized
business markets. Featuring 802.1Q
tunneling, high-performance IP routing,
and subsecond Spanning-Tree Protocol
(STP) convergence, this line of powerful,
yet cost-effective, fixed-configuration
switches enable a variety of metro services,
such as transparent LAN services and
business-class Internet access.
The Cisco Catalyst 3550 Series Intelligent
Ethernet switches include the following
configurations:
• Cisco Catalyst 3550-24 Switch—
24 10/100ports and 2 GigabitInterface
Converter (GBIC)-based Gigabit
Ethernet ports; 1 rack unit (RU)
• Cisco Catalyst 3550-24-DC Switch—
24 10/100 ports and 2 gigabit interface
converter (GBIC)-based Gigabit
Ethernet ports; 1 RU DC-powered
• Cisco Catalyst 3550-24-FX Switch—
24 100FX multimode fiber ports and
2 GBIC-based Gigabit Ethernet
ports; 1 RU
• Cisco Catalyst 3550-48 Switch—
48 10/100 ports and 2 GBIC-based
Gigabit Ethernet ports; 1 RU
• Cisco Catalyst 3550-12G Switch—
10 GBIC-based Gigabit Ethernet ports
and 2 10/100/1000BaseT ports; 1.5 RU
• Cisco Catalyst 3550-12T Switch—
10 10/100/1000BaseT ports and
2 GBIC-based Gigabit Ethernet
ports; 1.5 RU
The built-in Gigabit Ethernet ports
accommodatearangeofGBICtransceivers,
including the Cisco Course Wave Division
Multiplexing (CWDM) GBIC Solution,
GigaStack
®
GBIC, 1000BaseT,
1000BaseSX, 1000BaseLX/LH, and
1000BaseZX GBICs. High levels of
resiliency can also be implemented by
deploying dual redundant Gigabit Ethernet
uplinks, UplinkFast and Per-VLAN
SpanningTreePlus(PVST+)for uplink load
balancing. This Gigabit Ethernet flexibility
makes the Cisco Catalyst 3550 Series
switches an ideal metro access edge
complement to the Cisco 7600 Series
Internet Router and Cisco Catalyst 6500
Series of metro Ethernet switches.
