I had a nice long reply typed out and closed the tab.  The short summary is, as far as I can tell, the 6509 was shipped via a freight carrier or something. I'll have a look at it one of these days. We're happy to leave it sitting there forever. I'll be certain to include all pertinent troubleshooting information. I didn't spend my time in technical support, or berating techs now that I'm a sysadmin, to go and make someone elses life hell. (Or waste my time with half-assed emails.) I'm not certain on the exact part that needs to be replaced, but I do know that 0x2142 was being ignored and my NVRAM contents were being loaded, which was corrupt. Fun times were had by all.

I recertified on my CCNA a month back, taking the single test just like the original time. It seemed harder than the first time around especially considering I've got 3 years of decent level routing and switching experience under my belt. They sure do hit you with all the poo poo you might not commit to memory and you can find out by doing a show X or show Y. Luckily I didn't have the dreaded ISDN alphabet soup questions as I can never remember all of the position points and pieces, but I did get some ISDN questions about how to view call status etc. The test format itself has changed a lot, I certainly don't remember the multiple answer interactive semi-sim. I do like nitpicking their little questions though, like when you get asked in a sim to create an ACL list that blocks port 8 from IP x to IP y. Even if you do all the ACL work right you can still get to the web server from the place you arent supposed to. This made me panic a little thinking I had gotten the placement of extended vs standard ACLs mixed up, but when I reversed them I got the same results. Then to test my theory that ACLs don't get processed properly I created an ACL that would block outbound access to everything and sure enough, no change. So I set it up and away I go. I left a little note on that question saying that I should have gotten bonus points for troubleshooting the sim to provide supporting evidence for my answer. That question made me finish with 2 minutes left.

In this case, I would skip the part/model number, if your not sure, slap a 'Show Tech' attachment to the case, or if its not completing the boot process - just capture that, and let the engineer sort it out. Though, if its bad NVRAM I think the sup gets replaced. But don't take my word on that - theres no way I can memorize all the FRUable parts. And, again, contact asset recovery. They're your best bet to sort out the chassis mess.

I just had to do the math to convert some DSCP values into TOS, so I figured I'd share them, in case they might be useful. An IOS extended ping can be fed with a TOS value, and it's easier (for me, anyway) to be able to generate packets with explicit DSCP values than relying on another class-map to handle it somewhere. Anyway, I only bothered to do the three most common to our environment: EF 0xb8 (decimal 184, binary 10111000) AF31 0x68 (decimal 104, binary 01101000) AF21 0x48 (decimal 072, binary 01001000) Example: quote:
Kind of a handy trick.

I'm sure this is very simple to someone who knows what they're doing, but.... Thanks to jwh's help I found the cisco docs on DHCP servers, but I can't quite seem to get this thing going. As in, none of the PC's on my network are getting addresses when set to obtain IP's via DHCP. Anything obviously wrong with the following? quote:ip dhcp excluded-address 192.168.100.100 192.168.100.110 If that's not enough to help me out here's my complete config. I'm sure it's a mess, but as I said IOS is a strange beast to me and this is the best me and my friend  could come up with.If it matters, my network is structured like this (crappy Gliffy diagram):

The initial dhcp request isn't going to have an address from 192.168.100.0/24 to source from. Alternately add a deny any any log to the end of the acl, debugging dhcp would also be a good idea.

Oh man, I don't really know a whole bunch about Cisco stuff but my boss just asked for my help "designing" a network for a new school. Here's the break down: One main equipment closet, two wiring closets. They've specified 34 WAPs, 5 switches, and a router. There will be approx 150 drop, so we're going with 48 port switches obviously. This is what I'm thinking as far as the equipment, and it will probably be horribly retarded to you guys: 1x Cisco 2851 with whatever WIC they need 5x Catalyst 2960G-48TC 34x Aironet 1100 The 2851 will sit in the main closet with one of the 2960s connected via one of the FE ports. Two each of the 2960s will be in the other two closets with all four wired into the main closet's 2960 via SFP. The WAPs will be distributed evenly throughout. Am I missing something here? Should I add in something like a 3750 with 12 SFPs to ac t as a core switch (so it would be 2851->3750->->->->->2960)?

I wasn't even thinking too much about the WAPs. So switching to Aironet 1131AG for the WAP and a 4400 series for the WLC sounds about right? YET ANOTHER GLIFFY:  How does that look? I want to say thanks for the responses and help so far. The most I've done with Cisco is some small switches, a few 1700 series, and a couple 1800 series. I am just glad I don't have to configure this system.

What specifically is pointing you towards the 2851? If you only need an ethernet interface and WIC slot, you can do it cheaper than a 2851. 1841, for instance, or lower end 2800 series.

Robustness, I suppose. I want to give the client tons of expandability for anything they want to do in the future, thinking specifically of the NME modules. 4 HWIC slots, NME/D-X/XD, and GigE are the main reason. Since we don't know what exactly the client will want to do with it in the future, we're giving them the "best" in that range.

That premium your paying is for something that is going to work and be reliable. If it doesn't you have many avenues of support. Sometimes when pitching a more expensive idea, I'll do a little presentation on how it will actually SAVE the school money in the long run, by spending a little more up front. Throw out some good buzz words like "Total Cost of Ownership" (TCO) and throw in some neat words like "vertically integrated wireless solution" and other random BS. You'll dazzle them. Also I'm surprised no one has come up with the comedy option of "48 Linksys WRT54G's with DD-WRT" yet.

That's up to my boss. We have the electrical contract too, so they'll decide if it's cheaper to run electrical outlets or add in 48 port power injectors at each switch. I was looking at injectors by Powerdsine. I had thought of stepping up to Catalyst 3560 switches, but they're about double the price of the 2960 switches and I can't find any with 4 SFP ports. It's cheaper to get a 2960 and a Powerdsine injector than it is to get a 3560 with PoE. Edit: ^^ Good ideas. I will definitely be practicing before the pitch.

In an elementary school you will definitely not need anything more than a 2960. It's not like every computer will be in use at every second and I guarantee you that the network overhead of an elementery school won't be that high in general. It's not like a high school or college, where students are transferring large files and loving off on myspace (yet). Most elementery school computers are so locked down that bandwidth is litterally throttled due to stict access limitations. I would wager that a 2960 can probably suit the needs of a core switch in your case. When you design a network the most important thing to think about is who will use it. Determine your bandwidth needs and budget accordingly. The network that you have in mind is more than robust enough for the requirements.

That being said, however, the last exam I took was the BCMSN and to pass you needed an 804. In the PDF it lists 804 under CCSI Score and 755 under Cut Score. Not sure exactly what that means because the CCNA listed (the same version I took when I passed it) lists the Cut Score at 849 and the CCSI Score at 902, while to pass you need 849.

This is our single copper uplink port on one, during non-peak hours on a Friday: 5 minute input rate 160964000 bits/sec, 63472 packets/sec 5 minute output rate 424236000 bits/sec, 77443 packets/sec It gets up to about 700mbit output during peak hours.
