This is an add for a terminal server, does any one know about the 508-cs and would it be good for a lab

secondly with 2, 2501 and the 508-cs, would a 2503 or is it 2502 be a good investment for token ring, if not what would be the best set up?

I have not bought the 2501s yet, testing the water but the water will be warm soon

Thanks Chuck

Oops, this is not a Cisco 2509! Why spend over a thousand for a
2509 or 2511 terminal server or access router for just reverse telnet?
Cisco made one just for terminal server reverse telneting to console
port of other devices - WITHOUT the two sync serial ports. Model
500-CS series or more specifically 508-CS. You don't need no sync
serial ports if all you need is to reverse telnet. It runs IOS too and it
was made by Cisco so you CCNA/CCNP/CCIE candidates can
practice setting up reverse telnet on EIGHT terminal (tty) lines. It
comes with ethernet AUI port for ethernet interface connection. No
Async Octal breakout cable is needed. It uses the rollover flat
console cables. See picture shown. It is missing the small cover
plastic cover.

If you wan't to get through the CCNP first, I would stay away from the Token Ring, that is a whole new ball of wax. Those pieces of equipment are more staged for the CCIE Labs. All the CCNP exams are centered around Ethernet, there is no Token Ring.

As for the 508-CS, save yourself some time and just use the AUX port on your router if you want reverse telnet. You can plug a modem into if just like a dial-up. You can get an old external USRobotics, and make your own cable or buy one. It is an RJ-45 to a DB-24 connector. Recommend you get the cable and connector from Cisco if you do this. Will make sure you get the right pins connected.

This is common pratice for Network Admins to dial-into their routers if they loose network connectivity for those really remote sites that you just don't want to drive to. Just remeber to turn the modem off before starting the router, once you get 'green' on the router, you can turn it back on.

The Bottom Line A good home network requires time and
planning. I've been able to construct a rather robust network at
home and I didn't have to spend a lot of money.

As technology increases and more people begin to feel
comfortable with computers, the need to integrate a home
network will be common place for the average household. I have
written some instructions that even my grandmother followed and
now she is reading recipes straight off the Internet in her kitchen.
It's the Anarchist's Cookbook, but... granny doesn't seem to know
the difference.

My house consists of:
4 Workstations, 1 Laptop
1 Server
1 Belkin Box
3 Monitors
Lots of Cable

I recommend a Belkin Box for those people that have a server and
workstation close together. The four port Belkin boxes are
fantastic and save you a lot of space, not to mention money on
having to buy a monitor, keyboard and mouse for EACH machine.
The rear of the Belkin box allows you to use 1 Mouse, 1
Keyboard, and one monitor for each machine. Thin cables allow
you to easily connect other PC's to the rear of the device. There is
no software so it is extremely plug and play. Make sure that you
buy the connecting cables when you buy the Belkin box, they do
NOT come with it. The average Belkin box costs roughly $250.00,
but is cheaper than two monitors.

You will need an internet service provider. I recommend you locate
someone that can offer you DSL. If DSL is unavailable in your
area, find Cable... if Cable isn't available, dial-up is more than
likely your only real solution. Forget ISDN or T1, that is way too
expensive. Although, with this network diagram and instructions,
you can utilize this review to construct those types of networks
too.

Once you have an Internet device/method connected to the
internet, you probably will want to use the Internet on ALL your
computers. We can use a device called a Router, that does NAT
(Network Address Translation). You do not need more than 1
static IP address for your home network, period. I recommend the
SMC Router

http://www.smc.com/smc/pdf/Barricade.pdf -Roughly Costs
$139.00-

The Barricade Router allows you to connect:

1 Printer, Almost ANY Printer!
1 Modem, Either for Dial-Up, or a backup Dial-Up line in case your
DSL/Cable goes out
4 EtherNet Ports (If you need additional ports for more than 4
computers, you can connect a Hub)
1 WAN Port to connect your DSL Modem or Cable Device

(Note that the WAN Port on this unit does NOT take up an
EtherNet Port.)

Here is a diagram, for those of you that are visual:

http://www.StJamezPlace.Com/HMNetwork.jpg

The WAN IP address is the Wide Area Network Address that your
DSL/Cable/Internet Provider gives you. The LAN Addresses are
INTERNAL and most commonly are 192.168.x.x The SMC
Barricade Router comes with DHCP (Dynamic Host
Communication Protocol) and will create internal addresses for
you. You simply need to ensure that all your workstations are
setup for TCP/IP and DHCP in each machine's network
configuration panel.

Your Router that does NAT translates your internal address to the
WAN address through the router, so to your Internet provider, it
only looks like you are using ONE machine. Do NOT tell your
Internet provider that you are going to connect many PC's to their
service, they WILL add fees and charges and will probably lie to
you and tell you that you can't do it or that it can't be done. They
don't want you to use it, because it takes away bandwidth that
other users can utilize. They will try to sell you on getting a 5 IP
Address Static Account, (Kinda Expensive!)

Using the diagram above, you can see how the devices are placed
on the network. Note that:

The DSL Modem/Cable Modem provides the pathway to the
Internet.
The SMC Barricade Router provides address translation, print
services, DHCP for your internal network, and modem
telecommunications/faxing services.
Your computers provide the information storage and processing.

Note that you do NOT have to use the SMC Barricade Router.
However, I use it and it's SO easy to administer and setup. You
simply need a router or UNIX workstation that does NAT (Network
Address Translation) for your internal network if you choose
against the Barricade.

With an internal network you will be able to:

Share files, folders, and printers
Chat
Have Internet access on more than ONE PC at a time
Multi-User Game Stations (Doom, Myst, Diablo, Duke 3D,
Monopoly)

You do not have to have a server, but I do at home just because
I'm super nerd. I also have a lot of Pr0n.

Connecting all the PC's in your house is a big cable mess
depending on how you like to cable your home. However, some
cabling jobs that are done professionally look nice and neat like
your phone jacks. I simply run them over the carpet. WARNING: If
too many people step on or roll over with their chair the CAT5
EtherNet cable, it will degrade your performance on that device
and may cause damage to the machine/cable.

Networking your home is a chore, but this review, if followed, can
have you up and operational within a couple hours. I was able to
do this within about 1 1/2 hours.

Good luck! Email me with any questions.

Re: CS-508 ... I have a CS-516 (the 16-port version of the same box). It works fine.

Be aware that the IOS in ROM on most of them is very very antique (9.something), and is a serious pain to configure. I got mine with a software file for a 10.something IOS, which at least gives you a Router(config)# prompt to issue commands at.

There is no flash memory on these boxes; if you want to use a newer IOS (assuming you can get the software), you have to find the ROM upgrade chips (lots of luck!) or TFTP the IOS. I have mine set up to boot system tftp iosfilename.bin when I turn it on. If you can't get the newer IOS, you'll have to dig up some documentation on cisco.com and configure the thing once, and presumably never touch it again!

I paid about $225 for my CS-516.

Regarding token ring ... why NOT get token ring in the lab before CCIE? The routers are cheaper than ethernet. You just need 1 router with ethernet (ideally a 2620 or better for ISL) to play with whatever switch you have (if any). Token ring MAU's, cables, and a couple of NIC's will cost you less than the price difference in the routers. (Or you can just token ring the routers and get your PC in over a small ethernet segment).

FWIW,

I agree with the good Dr. While you may not yet need the token ring experience, you will and in the mean time those routers come with 2 serial interfaces for your other routing experiments.

I still hope Cisco drops TR in the near future like they did AppleTalk from the Lab, but that's just wishful thinking for now...

Doc and Yankee - thanks once again for the sound advice, so a 2501 and a 2503 would be good , for my first steps in building a lab - or stick with the dual 2501's - has any one heard from Skip?

ciao,

I suggest this because as Ethernet gets more prevalant in the industry, TR get less and less. I don't believe that it will every completly go away, FDDI and other technologies that use similar methods along with its strong load capability make it a strong competitor it will ever speed up again.

Anyhow, TR routers are cheap now, by the time you get close to the CCIE, they will be even cheaper. So why not spend you hard earned money on something that will help you now, unless you are going to jump straight to the CCIE?!?

TR will bind your time because you will need some equipment to go with it, hub (concentrator) or compliant network card for host, now with the money you will spend on that you can probably get two 2501's, spend half as much time, get a pro-level router setup going on and when you get ready to go for you CCIE, the TR router will be half what it is now.

Just trying to save you some money.

As for the story, you think that his home network is big, it's not that bad. I tool around quite a bit, got a Dual 1GHz PIII running Win2KAS, PIII 650MHz running WinMe(game computer), Sun Ultra Spark running Solaris 8, and a old Cyrix running Mandrake Linux 7.2. Firewalled and PAT by a 2621 off the Road-Runner with dial-up access via AS2509 when I need to get to my network remotly. I don't share a web site anymore but there are two running. The Spark is running iPlanet Web Application Server with PHP4 and EJava. The Win2KAS is running IIS 5.0 with ColdFusion 4.5 with an Oracle connector off the Spark running Enterprise Oracle 8.

Nope haven't heard from Skip and he's here in the Washington DC suburbs. Most around here aren't much in the mood for talking and I understand that fully so give him some time and I'm sure he'll be back soon.

Yeah, I got a little setup here also.

I have a custom-built rack-mount PII 350 server running NT4 that I built from the ground up running Symantec Personal Firewall. The server is dual-homed (one for Road Runner DHCP and the other for my privately addressed LAN). This provides a little bit of security in that they would have to take over my server in order to talk to my other nodes.

My workstation is an Athlon 1.2 running W2k Professional. It has 256RAM and an IDE UltraATA-100 Stripe set.

I plan to have a Cisco 3524-XL-EN switch soon and a couple of routers. When I get this equipment, I will run the roadrunner in to the hub I am using now, and plug the RoadRunner DHCP side of the NT4 server into the hub. This way, the hub services my DHCP Road Runner Subnet and my NT4 Proxy Server only has one interface in it. I'll take the Cisco 3524 and plug the other server interface into that along with the rest of my nodes. This way, the switch services ONLY my private subnet. The NT4 server will be providing NAT services by the proxy server. After this is done, I will be done with CCNP and be working on MCSE2k. I'll then install W2k Server and ISA.

I can't wait until that is done!

3C905C-TX NICs, the best!
