Please suggest me some switches with 48 ports. I will be using it in my colo cabinet, and plug in some 28-32 servers in total.
The features I am looking for are:
- It must have Gigbit uplink
- all 48 ports at 10/100 full duplex
- can measure bandwidth/traffic per port per month
- Decent Web based management
- Since I will be having client's servers, I want VLAN too, and some Web Based Management for it.
- I have /24 (256IPs, and basically I would like to assign 8 IPs per server in their own VLAN)
- I should be able to retreive nice MRTG graph for each port
- Some type of login system where user/client can login to see their monthly usage and MRTG graphs.
I have tight budget but I wont compromise on the quality, I want something which runs for long time rather than giving me trouble here and there always, and for that I am willing to put my money on it!
So suggest me something good and give me an idea on price for it.
A 2950 does support VLANs, however it does not have Layer-3 functionality, so there is no way to segregate your own VLAN's from the VLANs from your provider. That is where the 3550 comes in. Most people route a big block class C to your 3550 and then you take care of everything from there.
Unless you can find a steal of a deal on ebay or from a company selling refurbish Cisco's with a replacement warranty, most low-mid end models can be purchase new for only about 20% more than used if you shop carefully for a low priced vendor. If you go with a vendor like CDW.com then you're talking 45% markup over used.
Make sure to verify any vendor with reviews and confirm their warranty and return policies to ensure you're comfortable with them before purchasing.
Thanx for the info. My preference will definately for NEW CLOSE BOX, so far all the one I found are above 5K range (means i am definately not looking at right place), so can you give me some direct links here or by PM.
very much appretieate your help
BTW whats your opinion on DELL POWERCONNECTS 3000 series, on paper they look very good and price is in $xxx, are they reliable?
Well the 3550 with a Std image is about $3300 at http://www.computers4sure.com, techdepot.com, etc. Pretty sure that's Ingram Direct Pricing. Someone who buys Cisco in quantity might know a supplier with better pricing. The 3550 with Enhanced image would run another $1000 or so.
I wouldn't use a powerconnect switch anywhere besides home or a small office, that's my opinion. They're just cheap rebadged switches from budget networking companies that I wouldn't buy from in the first place. Cisco is just a great unit to start out with, very easy to find knowlegable qualified people to work on them, and the units are very reliable.

1) Can you advice more on difference between SMI & EMI
2) Do I need anything else other than switch, i.e. some accessories of any sort?
The 3550 SMI doesn't support any useful routing protocols. The EMI software supports OSPF and BGP. As long as you're a one-router (or layer-3 switch, in this case) shop with no redundant uplinks you don't really need this. You can upgrade to EMI later on.
If you're looking at 2950-series switches (you shouldn't be; this won't do what you've asked for) the EI software is required for policing or rate-limiting.
Most Cisco pricing is based off of list for new equipment.
You can expect to see anywhere from 25-40 points off list depending on who you are and who you buy from.
You could always check out www.usedrouter.com they have some pretty cheap Cisco gear there.
One thing with used Cisco is that it is not normally smartnettable so no warranty other than a 90 day or less from the person/organization you buy it from.
Also rate limiting on all of your ports does put a slight burden on the L3 switch im not sure how much it would introduce if all 48 ports were being limited. There is a pretty easy way to limit in IOS but you must put a slight overage amount for tiny bursts. I have the details on the script somewhere Ill find it and post.

The 3550/3650/3750 L3 switches, as well as the 2950/2970 L2 switches, perform all QoS functions in hardware.
As long as you don't configure so many L3 VLANs, carry so many IP routes, or otherwise over-configure your box you will never process-switch packets, they will always be handled by the hardware.
If you process-switch, though, QoS is not performed at all. Other behavior such as equal-cost-multi-path differs from process-switching to hardware forwarding as well. If you over-configure your box and end up process-switching these will probably be among the least of your problems, though. Just stick to <= 50 L3 VLANs and no more than a few thousand routes on the 3550 and it'll work fine and handle traffic at wire speed. The only thing you will need to worry about is making sure you have enough uplink capacity.
Hello Everyone who has contributed in this thread and few other threads I opened, I am very much thankful to you all, specially to jeff & scott shepherd for provide me their inputs on my questions and queries.
Here is my check list:
1) SWITCH - Brand New Cisco WS-C3550-48-EMI 2) SERVERS - Mix of PowerEdge 750, SC1425, 1850, 2850 (18 all together at the moment) 3) DATACENTER/BW - Bandwidth will be on a GigE drop. Regarding datacenter, have to clarify few things with James @ CRNC, based on that I will either go with CRNC @ Telehouse or my second option PEER1 NYC. All will be finalized today (saturday). Commute from NYC to Equinix, Secacus kinda pissed me off other day. Cabbie charged $50 from downtown Manhattan to Equinix, NJ, and another Cabbie charged $61 to come back from Equinix to manahattan. (which means if i have to even go twice in a month, there will be extra overburden of $250 in terms of commuting expanses.) While on other hand, commuting Telehouse-25Broadway or PEER1 doesnt cost as i just use my unlimited metrocard :-D
4) Accessaries - I am keeping 1 spare for each PowerEdge model server I have. 5 extra harddrives, plus mixture of DDR & DDR2 RAM in 256MB/512MB/1GB specification.
5) Operating System/Control Panel - Going with CentOS & CPanel and FreeBSDs. Will be keeping spare CDs at DC along with other tools.
6) CAT5e cables - Will be ordering some 30 10ft Cat5e in morning
7) Server Rails - Not decided yet as it is pending due to DC choice is not yet finalized.
8) Monitor - 17" Samsung SyncMaster 172x Silver LCD monitor (this baby is very slim, it can easily fit in 1 U space.)
9) Local Backup Server - MID ATX : P-4 2.8 GHz HT, 1GB RAM 6x300GB SATA, 4x250GB ATA, Total 2.8 TB space. I will be taking full incremental weekly backups of all the servers in cabinet on this baby.
10) Remote Backup Sever: Custom 3U rig with 12x250GB SATA, haven't decided yet where to colo it but probably this will be done in next few days.
11) REMOTE REBOOT - I am not sure which remote reboot system to get, and what exact components I need? To begin with, I will need a system which can support some 20 or so servers, and in long run it should be able to support some 35 servers. I will have 40-60Amp power on the cabinet. - SUGGEST ME SOME SOLUTION HERE PLEASE.
12) USER/CLIENT GUI - I need some sort of web based system where user/client can do the following as minimum:
a) Login to view their traffic/bandwidth usage for their servers.
b) Reboot their system remotely - SUGGEST ME SOME SOLUTION HERE PLEASE.
This is my checklist so far, please tell me if I am missing anything which I may need.
The dell one is currently $120 off the normal price, it's actually a good deal right now with free ship.
24 outlets, 20 amps. Make sure your rack accepts a NEMA L5-20 connection.
Depending on the PDU you buy like the higher end APC you can configure them for clients to login and reboot from them. You can find smaller units on ebay fairly cheap too. Just make sure to do your research on how to secure access to them.
Again, you need to use Cacti for clients to view their bandwidth with a login, or just setup a MRTG page for them.
