Cheapest Cisco layer 3 switches?

Paul Boz

I need to buy some switches for the BCMSN but I'd like to be relatively cheap in doing so. 3550's seem to be where it's at, but they're still relatively expensive. Anyone?

EdTheLad

One option 5505 with an rsm module,could get on ebay for $150.I'd see you a 5505 for $50 but you''l have to fly to Oz to collect as its to heavy to ship

Paul Boz

That's actually not a bad idea at all. I just added a 7206 to my lab, so I definitely understand the weight issue. Would you ship the thing if I footed the shipping costs?

EdTheLad

Nope,too much hassle. probably cost about $500 from Austrailia to the US.

Paul Boz

Oh man I totally missed where you said you were from over there, haha

OMG.....I can't believe this thread wasn't posted 2 days earlier...my friend JUST leave Melbourne to come back to Canada.

errr....

Hey guys, is this RSm only used for inter-vlan routing? Or can it be used for any layer 3 functionality?

I had no idea what an RSM was so i researched it a little and all I could find was inter-vlan routing whitepapers.

Can someone please give a little more detail on the RSM?

Also while on the subject, how many layer3 switches would one need to adequately study for the BCMSN and other CCNP topics?

Would 2 2550's and 4 2950's work?

I'm about to jump on BCMSN myself so this is a very interesting topic for me.

Thanks guys

RSM is basically a cisco 7500 series router as a blade that installs into a 5500 series switch. it gives you all the capabilities of a router for inter VLAN routing and what not. I am not sure what the most recent IOS is for it, the ones I have are running 12.0 so that may be an issue.

You can study most of the CCNP switching topics with 2 switches, although 3 would be better for things like spanning-tree and configuring trunks/vtp... One should be a L3 switch, and there are some topics about PoE (both prestandard and standard PoE which leads to a 3560 if you wanted to practice that)

Netstudent

wow, I can get by with only 2 or 3 switches? Cool!

I have access to 2 3550's and 4 2950's so I should be good to go.

So the BCMSN tests your ability to implement the topics, but it doesn't necesarily test your ability to implement those topics on a large scale.

Is that a sound statement?

I just assumed that the complexity of the material came in the form of scale in addition to the material. So the complexity of this test comes in the form of just the advanced topics themselves, CORRECT?

One other question while I'm here posting.

I have access to 2 Lab companion guides for the old tests. Specifically Advanced routing and Multilayer switching.

http://www.ciscopress.com/bookstore/product.asp?isbn=1587131447

Even though these are lab books for the old tests, would they still be beneficail in helping me prepare for the BCMSN? I guess what I am asking here is the material on those lab books still relevant to the new tests? I don;t mind studying the old material just to learn, but on the other hand I want something that is applicable to the newer test at the same time.

Thanks so much for helping me get a grip on what this test is about.

NS, I thought you were doing BSCI first??

Netstudent

I was going to, but I realized that BSCI is all routing. I have routers and I can always DL dynamips or buy a couple more cheap routers.

BCMSN requires some expensive gear and I am a broke college student. I mean ya I make decent entry level salary(31k), but not enough to be completely comfortable if you know what I mean. So i might as well get the BCMSN and maybe ONT done now while I have my schools VWICS/fxs, ip phones, and L3 switches just sitting around calling my name.

So I have changed my mind to make a long story short. Nothing changes as far as this coming up Tuesday. I'm still aquiring that collection.

Darthn3ss

what about 35xx switches? ie, 3548-xl-en? are those layer three or what? I've been wanting to get l3 switches to play around with myself...

Netstudent

i don;t know, I couldn;t find any documentation on them. Just wait untill lokee or someone else drops by, i'm sure they'll know.

All good man. I would do the same if I were in your shoes! I myself have changed direction just slightly... I am going to get my MCSA and then jump back onto CCNP for salary reasons as well. Most jobs in my area require a MCSA along with a CCNA... one is just not good enough hehe. So I am doing my 70-270 right now and I will be back doing CCNP at the end of October at the latest hopefully.

I was wondering a bit about the 3548-XL EN as well. I just got one of these from someone and would like to use it along with 2950s. I don't believe they can be used for L3 but perhaps dtlokee will know for sure.....3550 and 3560s are really nice but still pretty pricey.

dtlokee

Sorry fellas, been teaching CCVP all week 14 hrs a day not much time. The 3548 xl is a L2 switch no integrated routing. Although I understand the interest in having a L3 switch to practice with and it will help, but there isn't really much to pick up on for the L3 routing component you can't do by connecting a router to the switch.

ip routing
!
interface vlan 1
 ip address 192.168.100.1 255.255.255.0
!
interface vlan 10
 ip address 192.168.150.1 255.255.255.0
!
interface fa0/22
 no switchport
 ip address 192.168.200.1 255.255.255.0
!
router rip
 version 2
 no auto-summary
 network 192.168.100.0
 network 192.168.150.0
 network 192.168.200.0

No big deal, you can see the logic to it, basically a router with SVI's and the ability to take a L2 switchport and change it into a L3 interface with the "no switchport" command

If you're looking to stay on the cheap side, I would take what you have an hook it to a router with a FastEthernet interface and throw 12.2 (or an IOS comparable to one of the switch ios's, not 12.4 so you're not using the newest features.)

They arn't mine although I wish they were. Shoot i'm dropping 70K on this education I better be getting top of the line gear to learn on.

I just wish I had some technical trainers like Mr. derek over here, there is so much to learn.

And what I would do to be a network engineer...Oh wait i'm already doing it, just not quite there yet.

keenon

what a mess

ITdude

Ditto on Derek!!

aueddonline

I was on the look out for one to, how about the 2960 switch? thay seem to be about the same price as the 3550,

Darthn3ss

i think theres a 2900 switch that could route.. forgot the model number but i saw it somewhere :P

keenon

thats called a 2948G it runs CATOS

aueddonline

the 2948G is the 48 port version of the 2950 isn't it??


come on guys 2960 layer 3 switch anybody gor one?

dtlokee

2960 != L3 switch

The 2948G is a L2 switch, the 2948G L3 is a layer 3 switch. Both of them are CatOS so not very useful for current exams.

The part that says "OSI Layers: 2/3" is only because it can do IGMP snooping and things like that, a 2960 does not route, that is what most people are looking for when they say L3 switch, interVLAN routing.
