Intel Duel Over Dual-Cores
Dell will introduce a line of servers using the Intel
dual-core Xeon, while AMD has increased the speed of its
Default - Gateway
One point of confusion for some CCNA and CCNP candidates is the difference between configuring a static default route and using the Cisco routing command ip default-network.
And Building An Access Server
A Cisco access server is generally the last item a CCNA
or CCNP candidate has on their mind when they're putting
together a home lab.
One of the major topics on your CCNA and CCNP exams is Frame Relay. Additionally, Frame Relay is one of the most popular WAN technologies in today's networks.

Buying And Building An Access Server
A Cisco access server is generally the last
item a CCNA or CCNP candidate has on their mind when they're
putting together a home lab.
The thinking tends to be that since this router isn't really
doing anything in the production part of your practice lab,
it's not really important.
Once you have more than two devices in your home lab, though,
you'll realize that constantly moving the console cable around
from one router to another gets very tiresome. That's what an
access server does for a home lab - it allows you to connect
your PC to a single device when working in your home lab, with
no need to constantly disconnect and reconnect the console cable.
The console cable will be connected directly to the access server,
and the access server is connected to all the other devices
in your home lab. Once you start working with one, you'll wonder
how you got along without it!
The term "access server" is a little misleading. This is not
a server in the traditional sense, it's a Cisco router with
asynchronous serial ports. It is these ports that you'll use
to connect to the other devices in your home lab. Two affordable
models of access servers are Cisco 2509s and Cisco 2511s. They
can be found on ebay as well as other vendors on the Net.
You will also need an octal cable. On one end, the cable has
a large connector that will connect to the access server. The
other end is actually eight separate cables, each with RJ-45
connectors. These connectors are numbered 1 - 8 and will be
connected to the console port on each router and switch. It
is important to note the number on each connector you're connecting
to the other lab devices.
Now that you've got the physical equipment, let's take a look
at a typical configuration of an access server:

no service udp-small-servers
no service tcp-small-servers
no ip domain-lookup
