Product Overview

The Cisco Catalyst

Ethernet switches is a line of powerful,

ﬁxed-conﬁguration multilayer switches that

extend intelligence to the metro access edge,

enabling service breadth, availability,

security, and manageability. Key components

of the Cisco Metro Ethernet Switching

portfolio, these switches are ideal for service

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 10/100 ports and 2 Gigabit Interface

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

accommodate a range of GBIC transceivers,

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

Spanning Tree Plus (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.

Page 2 IP unicast and multicast routing and the Web Cache Communication Protocol (WCCP). After initial deployment, the Enhanced Multilayer Software Image Upgrade Kit gives users the ﬂexibility to upgrade to the EMI. The Cisco Catalyst 3550-12T and 3550-12G are only available with the EMI.
Page 3 Ethernet service breadth, availability, security, and manageability. Most important, the Cisco Catalyst 3550 Series is a key component of the Cisco Metro Ethernet Switching portfolio. For regional metro, metro aggregation and metro access, Cisco Metro Ethernet Switching enables service providers to deliver proﬁtable, comprehensive Ethernet services.
Page 4 In addition to Layer 2 VPN services, Multi-VRF CE (Virtual Routing Forwarding Customer Edge, also called VRF-lite) and Border Gateway Protocol (BGP) on the Cisco Catalyst 3550 will enable the creation of a Layer 3 VPN service by keeping separate routing tables for each VPN customer. Multi-VRF CE is a feature that allows a service provider to support two or more VPNs on a single 3550 switch, where IP addresses can be overlapped among the VPNs.
Page 5 The Cisco Catalyst 3550 is capable of performing rate limiting via its support of the Cisco Committed Information Rate (CIR) functionality. Through CIR, bandwidth can be guaranteed in increments as low as 8 Kbps. Bandwidth can be allocated based on several criteria, including MAC source address, MAC destination address, IP source address, IP destination address, and TCP/UDP port number.
Page 6 Metro network scalability is also enhanced by the Cisco Catalyst 3550 Series support of 4,096 VLAN IDs and 1,005 active VLANs per switch. VLAN trunks can be created from any port using the standards-based 802.1Q or the Cisco Inter-Switch Link (ISL) VLAN trunking architecture.
