Cat5K / 3920 Demo (?)

| I was referred by a co-worker to a vconsole.net as a reference point for the 3920 and Cat5K devices. He said I should know the workings of the 3920 "in my sleep".
Has anyone used the programs at this site? I am trepid of such simulators, but this person is very knowledgeable and he swears by them.
One last Q. He also recommended SolutionLab scenarios and was wondering if anyone could voice their opinion of these.
I am in the process of shelling out the $1000 for learning materials to prepare for the lab, and would like to get the most bang for the buck. | |

I don't know about that....
Maybe "Know the basics of the 3900 when you're considering taking a nap" would be more appropriate. I had never actually configured a 3900 before my lab, but I read the docs about it before hand. It took me like 10 minutes. If I knew it "in my sleep" then maybe I could have done it in 5. Somehow I managed to get by.... 
I can't really speak of the simulators, so I'm afraid I'm of no use (as usual). You definately need to know CatOS pretty well, though.

| Ya mean I wasted $1400+ buying one for my home lab? Say it ain't so!

Well, it's very handy to set up multiple rings on your lab. But..... you didn't ask me first.
At least you'll have those extra five minutes in the lab.

| ccboocamp is a reseller for a simulator
not sure if it's any good though | |

| I am thinking to order 2 2513(2 Serial, 1 Token, 1 Ether) so 2 TR interfaces will be enough in 2 different routers for CCIE home lab prep or not ?
ATM is there in lab exam or not ? These 2513 or 2501 can work as atm switch ? If no then which should be the minimun series router that can work as atm switch ?
plus wana confirm that these series routers can be Frame relay switch right ? Because i saw 3640 & more higher series routers as a frame relay switch .
I hope so you will guide me as you do always .

| 2 TR interfaces is probably fine. Don't forget you can always use the virtual-token ring interfaces in your labs. You can't test it, but you can still set it up if you need more rings.
If you want to switch ATM, I believe the only thing you'll be able to use is an LS1010. This is way overkill, and frankly, I wouldn't bother.
I don't know if you can use 2500s as a Frame switch, but I've never seen anyone do it. Everyone I've known has always used a 4000, AGS, 7500, etc.

| i have a 2520 w/ 4 serial acting as a frame switch
i have the same ios on other 2500's
i think it should work since you only need a 12.0 ios and the command frame relay switchng. | |

| Madchef & Darthfaces thanks for your reply . darthfaces How are you preparing for isdn , atm and Tokenring protion for ccie lab ? And if i am not wrong 2520 is having some low speed serials so for that you have to configure on the other routers also #bandwidth 128 in order to match the bandwidth correct ? | |
| Yankee 2002-03-24, 2:56 pm |
| Bandwidth is not used in actual speeds...only for meterics.
Yankee | |
| darthfeces 2002-03-25, 10:28 am |
| i just set clock rate
not worrying about speed , just simulating
wan links and protocalls.
not currently concerned with atm since it has
a lesser role. isdn can also wait as i can simulate dial technologies with aux and asynch
and a modem. i have a 2 2500's with token ports
so i can do bridging. | |

| We have ATM blades in our 7206 here.
But again way overkill for a lab. | |
| haseeb_eng 2002-03-26, 1:36 am |
| As all of you said that you are having your own home labs but from where you are getting complex scenarios ? Any specific book for Lab prep only with many lab scenarios with config guide lines ? | |
|

| I would suggest renting a complete rack at least a week before your lab. Knowing how to configure 3920 and ATM will definitely gives you extra points. For frame-relay, you can use a 2523. It has an 8 low-speed serial plus 2 serial ports and a token-ring port. Don't worry about the actual bandwidth of the port since you can use the command "bandwidth XXX" to trick your metric computation.
2 TR routers are not enough to enhance your skills in bridging scenarios since you have to practice back-up, border group, etc.

I would disagree. 2 TR routers is pleny. You can use virtual token ring interfaces if you need more. You'll be doing dlsw between ethernet segments as well, so you'll have pleny of devices with which to do backup peers, POD, etc.

| Madchef, I will assume that you are using IOS version 12.0 so you can set IP address on the virtual-tokenring interface. Since the lab is now on v12.1, what release on ver12.1 you are using to configure IP add on the virtual-tokenring? | |
| MadChef 2002-04-01, 5:27 am |
| I used 12.0 to prep for most everything, I believe. I can't say that I ever did assign an IP address to a vitual token interface. If I wanted to test IP, I usually used a loopback instead or in conjunction with the virtual token. About the only time I found myself using vitual token was when I didn't want to move cables around to place my TR routers where they should be and I needed TR specific functionality. There's only a handfull of things that can be done with TR that can't be done with Ethernet for DLSw, so I got by. Plus, there's only two TR in the lab.
