Q: Why make the

move to Gigabit

Ethernet?

The primary security features and applications supported by these switches include

access control lists (ACLs), filtering, port security, IEEE 802.1x, multilevel console

security, and Secure Shell (SSH) Protocol. This unique combination provides the

enhanced security needed to support new and expanding network services,

addressing three distinct areas of concern in the network:

•

Authentication

In other words, is the user supposed to have network access?

•

What's the user permitted to do on the network?

Authorization

•

Who's using the network and what are they doing?

Accounting

All together, the security features supported by Cisco Catalyst switches offer the

protection and control needed to prevent both malicious acts and inadvertent

mishaps.

These features can be used to address performance as well as security issues.

Hardware-based filtering, for instance, is typically used to screen MAC addresses

to restrict access to sensitive areas of the network. But it can also be used to deal

with a specific host that's been bogging down the network, denying it access while

allowing all others to enter. The protected port feature eliminates the possibility of

unauthorized IP traffic on virtual LANs (VLANs).

Finally, it's worth noting that Cisco Catalyst switches support applications to deal

with another concern: physical security. Their multiservice capabilities make them

ideally suited for IP video surveillance applications, providing an effective, yet

affordable, alternative to conventional video monitoring systems.

A: Because networks need room to grow.

At speeds of 1000 megabits per second (Mbps), Gigabit Ethernet provides the

bandwidth that networks need to evolve and meet new demands, alleviating

bottlenecks, boosting performance, and increasing the return on existing invest-

ments in infrastructure.

As the industry leader in LAN switching, Cisco makes the transition to Gigabit

Ethernet faster and easier with standards-based solutions for both fiber-optic and

copper cabling. Cisco products can also be deployed in stages for a more gradual

migration to Gigabit Ethernet, starting at the core and moving on to the wiring closet.

Organizations can use Cisco Catalyst switches to extend Gigabit Ethernet to the

desktop, simply and affordably, to support today's powerful computers, sophisti-

cated applications, and high traffic volumes. Delivering up to 10 gigabits per

second (Gbps), the range of solutions offered by Cisco will satisfy even the most

bandwidth-hungry environments.
