Well, I have the HP E4800 (==3Com 4800G) series running now for ~2 years in my network. And yes, I can recommend it. It has its disadvantages, but for the money you won´t find any better. Plus, if you buy the E4800-24G-SFP (JD009A) you can add a second power supply (JD362A). Btw, if you have some some 1Gbit/s SFP transceivers left from other manufacturers, you can put them into the 4800. It doesn´t matter if it´s from e.g. Cisco, Netgear, Brocade, Linksys,...

Well, Bugs, bugs, bugs, at least those which affected me. So, I´m staying on K14 on my 5400/6200/3500 fleet...

I really can recommend the HP V1910 series. Take it, forget the rest. For the money you won´t get any switch with similar features, plus you get HP lifetime warranty nowadays on these. Talking about prices, I can get those for 430,-€ incl. VAT. One hint, it doesn´t support stacking. Take a look at the firmware, Its size is currently over 10MB, yes that´s MegaByte. Update: Sorry, haven´t read the rest of your topic. Keep your 5400zl for your core and please don´t take the latest K.15 software, yet. Stay with K.14 for now...

HP 5406-44G-PoE+-2XG v2 (J9533A) ~4000,-€ incl. VAT

Interesting: http://www.tomshardware.com/picturestory/571-wi-fi-beamforming-networking.html http://www.tomshardware.com/reviews/wi-fi-performance,2985.html

What do you want to pay? Let´s look at the HP (ex colubris) series: - 1x HP 5406-44G-PoE+-4G v2 zl plus 1x HP MSM765 zl Mobility Controller (incl. 40 licenses): ~6000,-€ plus VAT. - 1x HP MSM460 Dual Radio 802.11n AP (HP MSM430 Dual Radio 802.11n AP (dual radio, 3x3:3 MIMO, 802.11a/b/g/n): ~440,-€ plus VAT. - 1x HP MSM430 Dual Radio 802.11n AP (dual radio, 2x2:2 MIMO, 802.11a/b/g/n): ~300,-€ plus VAT. - 1x HP 5 years software carepack (UQ611E): ~2900,-€ plus VAT.

Although they share the same policy on the radius, they all have different IPs and the RADIUS should therefore distinguish all requests. Am I wrong?

HP, Aruba, Netgear, Enterasys

Hi, I have some strange problems with our (different) wifi controllers. Our users use 802.1x (MS-CHAPv2/PEAP) to connect to our wlan system. The problem: The popup for authentication reappears several times, before they finally get in. First I though, hey, 802.1x, they didn´t setup the connection properly. You all know, 802.1x on e.g. Windows XP can be a little annoying... Some of my users don´t have problems at all, others have to retype their password and user 3,4,5 times to get in. But my controllers tell me that they can´t authenticate the users, because the RADIUS server doesn´t answer or that there´s a timeout. So, my RADIUS server is a Windows Server 2008 R2 being on a vmware system. Well, the system itself is actually a little bored. The cpus are far away from being overloaded. It is really strange, I can´t find the reason. And what is really annoying, I can´t find useful logging data on the Windows Server 2008 R2. The setup ist really simple. No NAP so far. Just authenticate and voila you should be connected. filter-id is given back to the controllers. Perhaps someone of you knows, what´s going wrong?

Famous Ashby Radius? Can you please give a link?

Well, he could use two Netgear WFS709TP controller and convert its WAG102 into WAGL102

ring topology or do some more meshing; run e.g. OSPF within the P2P links between them. So that ring would be your core. Every building gets its owh subnet. You want wifi? Depending on the distance, put in something like like the Nanostation from Products | Ubiquiti Networks, Inc. with strong antennas for layer 2 connectivity. For the routing part you can take e.g. Mikrotik 450G.

Well, of course without the warranty for year 4 till replacement, I will have no next business day. But for this I could buy several additional non lifetime switches for instant replacement and save also money. I once bought a 2910al because of its warranty and hey I saw that looking at performance, it has higher specs than a 3500yl/6200yl, but its feature set is limited. I also have some HP 8000M and hey I have lifetime warranty, but what about features? Give me a working vlan aware loop detection feature on one port instead of lifetime warranty. Of course I like HP´s warranty and I was happy when HP aquired 3Com/H3C. Now I have some nice 3Com switches with HP label and some even not got HP´s real lifetime warranty. Talking about the V1910, for the price it´s a bargain, if you want lifetime warranty buy something else. (Do not take the V1905 series. It´s completely different)

Hm, I do not unterstand your argument: HP 1810G (24 port): price: ~170,-€, data sheet: HP V1810 Switch Series (QuickSpecs/c02891932.pdf) HP V1910 (24 port): price: ~230,-€, data sheet: HP V1910 Switch Series (QuickSpecs/c02711798.pdf)

Sorry guys. But lifetime warranty is not everything that counts. i need a switch that support the protocols and features that I need, constant software updates. Therefore a HP V1910 (== 3Com 2928) will beat e.g. a HP 1810 switch.

If you don´t need POE+ or RIP and POE is sufficient, take a look at the HP A5120-48G-PoE EI (JE071A) http://h18000.www1.hp.com/products/quickspecs/13850_na/13850_na.PDF price is ~2600,-€ incl. VAT

6 weeks ago, I purchased a HP 625 (Athlon II P360 2x 2.30GHz • 4096MB • 320GB • DVD+/-RW DL • AMD Radeon HD 4200 (IGP) shared memory • 3x USB 2.0/LAN/WLAN 802.11bgn/Bluetooth • HDMI • ExpressCard/34 Slot • SD-Card Slot • Webcam (2.0 Megapixel) • 15.6" WXGA non-glare LED TFT (1366x768) • Red Flag Linux • Li-Ionen-Akku • 2.49kg ) price was 289,-€ - 10% coupons - 50,-€ cashback by HP

We are using a ring of 4 fiber (1Gbit/s) lines connected with LACP. Switch is HP E4800. 10Gbit/s isn´t needed and won´t be within the next 5 years. LACP with 1Gbit/s modules is cheaper...

Thanks to a public tender we are "forced" to take HP E4800 swtiches. These are former 3Com 4800G devices. We are running OSPFv2/v3 with PIM-SM (IPv4) so far. And yes, we are using this switch for core, distribution and access. You can stack these as well, although some additional modules are needed. One great thing is, that they also have HP´s lifetime (hardware) warranty. specification sheet: HP E4800G Switch Series (QuickSpecs/c02514897.pdf)

No, the 3500yl was never meant to be a core switch. Take two HP E4800-24G Switch instead, make a IRF stack with two Local Connection Modules and two CX4 cables. Talking about prices: 4200,- € for the switches and LCM, plus 200,-€ for the CX4 cables incl. VAT. (If you want something "bigger" and more advanced (MPLS support) and if more 10Gbit/s interfaces are needed, take a look at the A5800 series. They have inbuilt SFP+ slots. Take two HP A5800-24G Switch plus two HP X242 SFP+ SFP+ 1m Direct Attach Cable for stacking and pay 6100,-€ incl. VAT.)

Talking about HP - There are the mentioned Colubris based ones: e.g. the MSM460 with 3x3:3 MIMO looks nice, plus e.g. E-MSM76zl controller - And the H3C based devices: WA2620E with "only" 3x3:2 MIMO. HP A-WX5004 would be the controller. It would be great if you could take a look at both.

I like the new Unifi software. Unfortunately the amount of SSIDs on their access points i currently limited to 4. Also the dualband version of their access point is not yet released. Unfortunately, IPv6 is not being talked about at Ubnt. When all these topics are being covered in 09/2011 I will definitly try them out.

Go for a 3Com 4800G or now HP E4800. As you need more fiber connectors get the 24x SFP version. It also has 8 shared copper ports. Talking about comparison: Comparison of stackable switches - Wikipedia, the free encyclopedia

We are using Aruba 800 controllelrs with Aruba a/b/g access points. ~2 years ago we added Netgear WFS709TP controller, as those are relabeled Aruba (with limited software) but with much lower costs. Unfortunately current Netgear wifi systems are no longer based upon Aruba...

Hi, may I ask what product is now EoL? Talking about Netgear. Pricing is really nice. I do like their new 30 year warranty and I used it many time. I had some GS724T V1 with defective fans. The whole switch was replaced by a new one. This was GS724T version 3. The software was completely new, meaning the switch hardware was completely different. And here is the disadvantage of Netgear products. Netgear buys its switches from different hardware makers. You don´t know what you really get as Netgear seems not to build those devices on its own.
