SDM in home lab

SdotLow

So I've been playing with getting SDM working on my home lab this evening and have had a couple issues crop up. I'm wondering if what I'm trying to do is beyond the scope of CCENT/CCNA (I don't think it should be since my lab is a SOHO but I could be wrong).

IOS Version - c2600-advsecurityk9-mz.124-9.t1.bin. 2620xm router.

Was trying to get SDM running but I don't have a crossover cable at the moment.

Problem #1 - Ran my main PC into a switch. Changed the IP of the router to 192.168.1.1, switch ip address is 192.168.1.2, PC set to 192.168.1.29. All with /24 mask. I don't get an error when SDM starts, but it doesn't go beyond the first window for SDM v2.5, the window that lists "Mozilla V.xx / Java V.x". Is this not feasible, do I need an internet connection (a feed to my ISP) for this to work? I assumed it would work just fine like my web based routers (cheap linksys ones) always have without an internet connection.

Problem #2 - Assumed problem #1 was related to no net, so I reconnected my PC to the Verizon FIOS router, ran a ethernet cable to my 2620XM FA0/0 port. This did the trick letting me into SDM. Got all the pop ups. Once I got into SDM though, I couldn't do a lot of things. A box would be clickable, and once I would click it it would grey out. I had no DHCP settings available. The bottom box on the left bar "Advanced/extra options" or whatever it was, when clicked, did nothing. Literally nothing. I've been digging around the Cisco site and can't find any confirmation or otherwise saying 2620xm doesn't support DHCP.

Sorry for the wall of text, figured I'd lay it all out and hope someone can eliminate one of the walls I'll be banging my head on tonight.

With problem #1, I have no idea why it didn't work, when it did when you arrived at problem #2.

But for problem #2, I can say with quite certainty that the issue is with the version of java you have installed on your PC. I get the best results with Java 1.6u3. SDM is pretty old now, and things just don't work right with more recent versions of Java.

I've downloaded and installed Java 1.6.03 and the initial web site that pops up for SDM say java is not enabled. I did remove 1.6.26 because disabling in the java version tab did not get SDM up and running.

Any suggestions?

I also had this problem recently, although I was using the SDM demo rather than trying to configure a physical router. Hopefully this should still help.

The way I got it to work was uninstalling all Java versions. Rebooting, installing Java version 1.4.2_05.

After installing that and disabling popup blocker, I was able to load SDM and get into the advanced section to create DHCP pools etc.

Software used:

OS - XP Pro SP3
IE version - 8

Hope this helps. No internet connection required by the way.

I finally figured it out. The problem is apparently Mozilla Firefox. As soon as I removed Firefox, reinstalled java, and used IE it worked. My desktop still hangs up for some odd reason but my laptop has 100% functionality.

Ain't SDM great?

Heh, no. I actually don't like it at all. I'd rather be in CLI. I don't see how the CLI DHCP config is anywhere near as time consuming as it took for me to get SDM working ;(

I've heard Cisco is going to be releasing a replacement for SDM though, so maybe it will have some support in terms of compatibility.

Yea... SDM if extremely finicky at best. When I was studying for my ENT, I spent a whole evening trying to get it working and about 10 minutes actually using it. It was terrible. I would suggest sticking with CLI, I have a feeling that cisco knows how bad sdm is and, for that reason, don't base much of the exam topics on it.

That being said, still know it just in case

I spent the span of probably 20 hours to get it working. Part of my problem was, I had a gut feeling that Firefox wasn't playing nice with it but setting IE to default would not let SDM load using IE. I had to manually remove Firefox from my system in order to get SDM to use IE (and I waited to do this last because I don't like IE at all). First try with IE after removing Firefox it started. Still can't get it to run on my desktop for some reason.

You think thats bad? Try getting it to work in Linux. Took me hours, and a lot of googling, but I got it working.

Keep that mindset. IMO, you don't need the SDM, just learn everything in the CLI and you will be fine. When the GUI breaks or Java decides to act up your back to GUI anyways so you might as well just stay there.

That is my feeling as well. I was a bit dumbfounded last night when taking my Exsim-Max practice test and I ran across needing to know specific DHCP configs. It's a good thing I set my SDM to always preview commands before sending them to the router.

I'd love to just stay in CLI 100%, trust me lol.

I would just stay CLI, don't get caught up in the SDM because it is not going to help you any. I do not know of any network engineers that use SDM in an actual environment. The only thing even close is the ASDM for ASA firewalls, but it is 10000x better than SDM. All your exams will test you on CLI configs and output so I would drop it now before you invest too much time in it.

I was under the impression the actual Cisco exam will test on being in, and using the SDM environment for DHCP and/or NAT/PAT. I don't want to shoot myself in the foot and not be prepared for a question. You know?

My mistake, I just looked back at the blueprint and seen the SDM. Personally it is one of the few things I think it's waste of time to learn, but since it's on the exam I guess you have to at least look at it some. At least you will only have to deal with it for these topics

• Enable NAT for a small network with a single ISP and connection using SDM and verify operation using CLI and ping
• Configure, verify and troubleshoot DHCP and DNS operation on a router (using both CLI and SDM)

You could always get those out of the way, at least then you can get into the real stuff in the CLI.

I was told that, while I could probably get by without using SDM for ICND1 and just going off what is in the books, I would need to be able to use it for ICND2.

Not true? I hope so.

Yeah I had looked over that, and I didn't see SDM listed on there. I recall someone on the Cisco website study group mentioning it's used in ICND2. I'll have to go look and get some clarification.

Those people might have gotten the CCNA book that covers both exams. You can't go wrong with the blueprint.

Why would you go through all that trouble? I understand SDM is java-based and only use the web browser, but couldn't you just use virtual machine instead?

If you progress to CCNA Security you'll become even more intimately familiar with it.

That "was" my plan. Now? I don't know about that. I've heard Cisco will be replacing SDM with something in the near future.

I gotta admit it looks a lot sexier than the sh*tty SDM.

Yeah I know, a pointless exercise really. It should have been easy enough to do, but of course things never quite work out that way. And once I'd started on it I had to finish it.

Its mostly just lipstick on a pig. A lot of the screens are actually the same as the ones in sdm. However i have had better luck with it than sdm although i know a lot people that have had terrible luck with it.

I don't think Miss Piggy would appreciate what you just said. Anyway, the most important thing is that we would be able to get the newer version to work without toying around with it for hours.
