Web-Based Switch Management:

Cisco Visual Switch Manager

The Catalyst 3500 series XL features the Cisco Web-based

management tool, Cisco Visual Switch Manager (CVSM),

which allows network administrators to view and manage a

switch from anywhere on the network through a standard

browser such as Microsoft Internet Explorer or Netscape

Navigator. CVSM is launched from the switch itself and

delivers simple network- and device-level management,

including port conﬁguration, VLAN setup, network views,

and port monitoring. CVSM is an integral part of the Cisco

scalable stacking architecture, allowing users to easily

conﬁgure and manage stacks and switch clusters and

administer software upgrades across multiple switches.

Standard Edition Software

Cisco Catalyst 3500 series XL Standard Edition switches

include several exceptional features to increase network

performance, manageability, and security. The command

switch feature delivers single-IP managed Cisco Switch

Clustering technology to up to 16 interconnected Catalyst

3500 XL, 2900 XL, or Catalyst 1900 switches. Fast

EtherChannel and Gigabit EtherChannel technology offer

from 400-Mbps to 4-Gbps high-performance bandwidth

among Catalyst switches, routers, and servers. The Cisco

Group Management Protocol (CGMP) enhances

performance of multimedia applications and reduces

network trafﬁc by allowing a switch to selectively and

dynamically forward IP multicast trafﬁc to targeted end

stations. Up to 250 port-based VLANs per switch allow data

packets to be forwarded only to stations within a speciﬁc

VLAN,creating a virtualﬁrewall between groups of portson

the network. Network Time Protocol (NTP) provides a

uniﬁed clock across the network, ensuring accurate time

stamps for troubleshooting all network events. MAC-based

port level security prevents unauthorized stations from

accessing the switch. Multilayer security on the switch

console prevents unauthorized users from accessing or

altering switch conﬁguration. All Standard Edition switches

can be upgraded with the purchase of an optional Catalyst

3500 XL Enterprise Edition upgrade kit.

Enterprise Edition Software

Enterprise Edition software includes all of the features of the

Standard Edition and adds enhanced end-to-end VLAN

support to your Catalyst 3500 series XL switch. Virtual LAN

trunks can be created from any port using either 802.1Q

trunking or the Cisco Inter-Switch Link (ISL) VLAN

architecture. VLANs using standards-based 802.1Q and ISL

trunking provide broadcast control and enhanced security,

and simplify adds, moves, and changes. TACACS+

authentication enables centralized access control of the switch

and restricts unauthorized users from altering the

configuration. Uplink Fast technology ensures quick failover

recovery, enhancing overall network stability and reliability.

An Enterprise Edition switch is the best choice for use in a

network with the requirement of higher level of security,

superior fail safe redundancy, and end-to-end VLANs

spanning multiple routers, switches, and access servers.

Applications

The three major product applications of the Catalyst 3500

series XL are deﬁned as follows:

• Desktop—The switch is used for desktop connectivity

providing dedicated 10 or 100 Mbps to workstations and

servers and deployed as a standalone unit with a unique IP

address. This application typically requires a higher

density switch to achieve a lower per port cost. Gigabit

Ethernet ports will be used for uplink connections to the

corporate backbone.

• Stacking/Clustering—Several Catalyst 3500 XL, 2900 XL,

and Catalyst 1900 switches deployed in a switchclustering

or GigaStack GBIC conﬁguration and managed with a

single IP address. The switches are used mostlyfor desktop

connectivity with limited aggregation. Gigabit Ethernet

ports will be used for uplinks to corporate backbone or

connections to a Gigabit aggregation switch.

• Aggregation—The 10/100 and Gigabit Ethernet Catalyst

3500 series XL switches are used to aggregate several

10BaseT and 100BaseTX switches and hubs, and servers

into a common backbone. This application typically

requires a lower-density, high-performance 10/100 switch

with12to 24ports.Some customers mayrequire dedicated

Gigabit Ethernet switches (Catalyst 3508G XL) to

aggregate several 10/100 switches with Gigabit Ethernet

uplinks.
