Cisco 3508G - Catalyst XL Standard Edition Switch Manual de usuario descargar pdf (Pagina 2)

Catalyst 3500 XL switches can be conﬁgured either as

command or member switches in a Cisco switch stack or

cluster. The command switch serves as the single IP address

management point and disburses all management action

dictated by the network administrator. Command switches

can cluster up to 15 additional interconnected member

switches, regardless of their interconnection media. The

Catalyst 3508G XL is an optimal command switch when

deployed as a high-performance aggregator.

Web-Based Switch Management:

Cisco Visual Switch Manager

The Catalyst 3508G XL features a Web-based Cisco

management tool, Cisco Visual Switch Manager (CVSM),

which allows network administrators to view and manage

the switch from anywhere on the network through a

standard browser such as Microsoft Internet Explorer or

Netscape Navigator. Launched from the switch itself, CVSM

delivers simple network- and device-level management,

including port conﬁguration, virtual LAN (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 for up to 16 interconnected Catalyst

3500 XL, 2900 XL, and Catalyst 1900 switches. Gigabit

EtherChannel technology offers higher-performance

bandwidth between Catalyst switches, routers, and servers.

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 virtual ﬁrewall between groups of ports

on the network. Network Time Protocol (NTP) provides a

uniﬁed clock across the network, ensuring accurate time

stamps for troubleshooting all network events. Media

Access Control (MAC)-based port-level security prevents

unauthorized stations from accessing the switch. Multi-layer

security on the switch console prevents unauthorized users

from gaining access and altering the switch conﬁguration.

All Standard Edition switches can be upgraded with the

purchase of an optional Enterprise Edition upgrade kit.

Enterprise Edition Software

Enterprise Edition software includes all the features of the

Standard Edition, and adds enhanced end-to-end VLAN

supportto your Catalyst3500 series XLswitch. VirtualLAN

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 choicefor a network

requiring a higher level security, superior fail-safe

redundancy, and end-to-end VLANs spanning multiple

routers, switches, and access servers.

Key Features/Benefits

Exceptional Performance

• Eight GBIC-based Gigabit Ethernet ports deliver

up to 5-Gbps aggregated forwarding bandwidth to a

switch cluster.

• 10-Gbps switching fabric and 7.5 million

packets-per-second forwarding rate.

• 4-MB shared-memory architecture ensures the highest

possible throughput, with a design that eliminates

head-of-line blocking, minimizes packet loss, and delivers

better overall performance in environments with extensive

multicast and broadcast trafﬁc.

• Full-duplex operation on all ports deliversup to 2 Gbps on

1000BaseX ports.
