VLANs ensure that data packets are forwarded only to stations within a speciﬁc subnet, creating a separate collision

domain between groups of ports on the network and reducing broadcast transmission. VLAN trunks can be created

from any port using the standards-based 802.1Q or Cisco Inter-Switch Link (ISL) VLAN trunking architecture.

The Cisco Catalyst 3550 switches support up to 1,005 VLANs.

For even greater security between network end-stations, Private VLAN Edge isolates ports on a switch, ensuring

that users cannot snoopon other users’ trafﬁc. Local Proxy Address Resolution Protocol (ARP) works in conjunction

with private VLAN edge to minimize broadcasts and maximize available bandwidth.

Network Management with the Cisco Cluster Management Suite Software

The Cisco CMS is Web-based software that is embedded in Catalyst 3550, 2950, 3500 XL, 2900 XL, 2900 LRE XL,

and 1900 switches. Through Cisco Switch Clustering technology, users access Cisco CMS with any standard Web

browserto manage upto 16 ofthese switches atonce, regardless oftheir physical proximity—with the option of using

a single IP address for the entire cluster if desired. With the addition of the Catalyst 3550 switches, Cisco CMS

Software can now extend beyond routed boundaries for even more ﬂexibility in managing a Cisco cluster.

Cisco CMS provides an integrated management interface for delivering intelligent services, such as multilayer

switching, QoS, multicast, and security ACLs. Thus, Cisco CMS allows administrators to take advantage of beneﬁts

formerly reserved for only the most advanced networks without having to learn the command-line interface (CLI)

or even the details of the technology.

The new Guide Mode in Cisco CMS leads the user step-by-step through the conﬁguration of high-end features and

provides enhanced online help for context-sensitive assistance. In addition, Cisco AVVID (Architecture for Voice,

Video and Integrated Data) Wizards provide automated conﬁguration of the switch to optimally support video

streaming or videoconferencing, voice over IP (VoIP), and mission-critical applications. Additional wizards for LAN

security and multicast trafﬁc are available too. These Wizards can save hours of time for network administrators,

eliminate human errors, and ensure the conﬁguration of the switch is optimized for these applications.

Because Cisco Switch Clustering technology is not limited to a single stack of switches, Cisco CMS expands the

traditional cluster domain beyond a single wiring closet and saves time and effort for network administrators. The

switches must merely be connected to each other via Ethernet, Fast Ethernet, Fast EtherChannel

, Gigabit Ethernet,

Gigabit EtherChannel, and/or Gigastack connectivity.

Cisco Catalyst 3550 switches can be conﬁgured either as command or member switches in a Cisco switch cluster.

Cisco CMS also allows the network administrator to designate a standby or redundant command switch, which takes

the commander duties should the primary command switch fail. Other key features include the ability to conﬁgure

multiple ports and switches simultaneously, perform software updates across the entire cluster at once, and clone

conﬁgurationsto other clustered switches for rapid networkdeployments. Bandwidth graphsand link reports provide

useful diagnostic information and the topology mapgives network administrators a quickview of the networkstatus.

In addition to Cisco CMS, the Catalyst 3550 products are manageable via CiscoWorks products, which provide

full enterprise-class network management. CiscoWorks Resource Manager Essentials (RME) can be used to perform

network-wide software upgrades, conﬁguration ﬁle audits, conﬁguration ﬁle distribution, and inventory reports.

Additional tools include the Campus Manager, CiscoView, Device Fault Manager (DFM), QoS Policy Manager

(QPM), User Registration Tool, and many others. For smaller networks, CiscoWorks Small Network Management

Solution (SNMS) provides advanced network management capabilities to reduce IT administrative overhead.
