Cisco WS-X6066-SLB-APC-RF - Content Switching Module Instrukcja Użytkownika Pobierz pdf (Strona 7)

The LAN switching infrastructure connects users, applications,

and communications systems together. That basic task has become

much more challenging as the variety and complexity of network

uses have increased. Cisco Catalyst switches provide the intelligent

services required to create secure, resilient networks that optimize

the delivery of disparate services, yet remain easy to configure,

manage, and troubleshoot.

End-to-end intelligent switching

for today’s converged network services.

Cisco Catalyst switches support today’s technology trends and business goals

through a unique combination of intelligent capabilities Major advantages include:

Integrated Security

Cisco Catalyst switches help make networks

self-defending Encrypted passwords, multilevel

account privileges, and authentication protocols

prevent unauthorized network access—a

problem exacerbated by the rapid adoption

of wireless networking The switches can

also prevent devices from connecting if they

fail to meet certain criteria, such as having

the latest antivirus software Users can be

separated into private subnets to permit varying

levels of access Other features enable the

switches to protect themselves from worms

and denial-of-service (DoS) attacks, prevent

routing and spanning tree information from being

spoofed, and ensure malicious users can’t steal

confidential information, either from the company

or from other employees Flexible Packet

Matching (FPM) also provides protection against

notable worms and viruses and day zero attacks

Non-Stop Communications

Cisco Catalyst switches help maintain the

highest levels of network availability and

resiliency Each switch is designed to protect

itself from hardware, software, power, or

connection failures

—

or at the very least,

minimize recovery times by enabling redundant

backup systems and protocols to take over in

as little as a millisecond The switches are

also designed to increase resiliency on a

network-wide level, utilizing an array of Cisco

innovations to recover from device, link, or

protocol failures and maintain uninterrupted

access Integrated security features also play

a role in preserving availability in the event of

incidents like DoS attacks Conversely, resilient

designs help networks recover faster from

security breaches, or even nullify their impact

Application Intelligence

Today’s networks must be intelligent and

adaptable enough to meet the varying

requirements of converged data, voice, video,

and storage traffic Cisco Catalyst switches

optimize the delivery of disparate traffic

types using four key technologies: stateful

application intelligence (SAI), quality of service

(QoS), multicast, and content switching SAI

provides IT managers with visibility into

application bandwidth requirements on the

network SAI also gives IT managers the power

to take control of application performance by

prioritizing, deprioritizing, limiting or blocking

traffic based on application type QoS allows

network managers to prioritize traffic and

ensure low-latency traffic, such as voice, gets

handled accordingly Multicast makes it much

more efficient to deliver video or music on-hold

to multiple points on the network, reducing

the burden on servers The Cisco Catalyst

6500 Series Content Switching Module adds

advanced Layer 4–7 load balancing to the

Catalyst line’s existing Layer 2 and 3 features,

further optimizing service delivery

Operational Manageability

All Cisco Catalyst switches offer enhanced

capabilities that make them much easier to

configure, manage, and troubleshoot These

include wizards that automatically configure

switches, integrated Web-based management

tools, device discovery and intelligent power

management features for PoE equipment such

as IP phones and wireless access points, and

an array of data collection and analysis tools

The benefits are real-time visibility, faster

response and repair times, more adaptive policy

management, and reduced cost and complexity

In the case of the Cisco Catalyst 6500 Series,

optional Network Analysis Modules (NAMs)

embed a rich set of management features on a

single blade, providing volumes of performance

information without burdening the switch itself
