HP ProCurve 2520 - Network Switch Replacement
May 1, 2013
we're running some HP ProCurve 2520's (24 port PoE for desktops/phones) and 2510's for our server racks. The CPU's are a bit weak from what we can tell and sometimes end up with issues on them. The specs on the EAS series look like a decent jump compared to the older HP's. However I've never worked with these ever.
My other option is to go back to Cisco. However to make it fit our budget, we have to dump gig switches for 10/100 + PoE. Which isn't really a major issue on the desktop switches. We'll naturally put gig versions on the server racks. I like our ProCurves, however they cause issues from time to time.
I've also considered going back to Adtran, however I haven't kept up with what they have to offer. I'm tempted to play it safe and go the Cisco route. We're using ASA5510's active/passive for routing/firewall (gig versions).

I'm trying to determine what switches in the Procurve lineup will do Inter-VLAN routing on the same switch. Assume a basic 1 switch network.
I've determined that Procurve "Layer 3 Lite" will do static routing but not dynamic routing. So I would assume their Layer 2 switches do absolutely no routing. However I have a 2520 in front of me that HP claims is Layer 2 only yet I can route between VLAN's on that switch.

I am facing this trouble since i purchased this laptop i have a Dell vostro 2520 running on windows 8 pro X64, so the problem is that whenever i try to install drivers for Ethernet which i downloaded from the drivers and download section of this website it gives me an error "Realtek network controller was not found If in deep sleep mode please plug in the cable" now the thing is that it cannot be a problem in my windows as i was running on windows til few days ago, I got the same problem in windows 7 as well,
I have searched everywhere and i have tried almost every solution i got but to no avail the problem still persist and i cannot use LAN for Internet or file transfers,
P.S:- I looked for the adapter under the "control panel system and security system device manager Network adapters" But didn't found anything there saying Ethernet or something like that.
I am uploading the screenshots of the problem i am facing.

My current switch layout at work is very basic and offers no redundancy. I'd like to at least setup redundant core switches, so that if any of my switches would to fail, it would result in a smaller number of systems affected.
Current Core Switch: HP Procurve 3500yl-48G (3500yl-24G as cold spare)
Internet Switch: 3com (forget model)
User distribution switches: 9 Planet 10/100 Layer 2 Managed switches, and 2 Dell Powerconnect 5448
Server switches: 5 Procurve 2810-24Gs (1 in each server rack)
In addition, we have 50+ site to site VPNs using different 192.168.x.x subnets across 2 different VPN concentrators, several routers, and a pair of MPLS's.My first step to improve speed and reliance was to reconnect the user switches. The old distribution switches were daisy chained, and all users 120 users were on a single 1GB port on the core switch, and if switch 2 of 11 failed, I'd have 10 switches knocked out of the network. I've since connected them directly to the core switch, and the users have noticed the improvement.
I'll try to get a diagram, but it's basically a large hub and spoke. Each and every switch is connected directly to the single core switch. All of the internet sources are connected directly to the 3com and are on separate VLANs which are then connected to the core via a trunk, which then handles the routing. Currently, I'm using less than half of the ports on the current core switch, so I should still have enough ports on the 24G to at least maintain the critical systems. Each server switch is trunked to the core, as is the internet switch, but the user network is not (but probably should be). Instead they are connected via simple untagged uplinks.
I absolutely cannot afford new equipment right now, so whatever I do will require reusing existing equipment. I'd very much like to increase the bandwidth from the server switches to the core if at all possible. Is there an easy way to configure and Active-Active setup that would improve bandwidth? Or would It be active-passive and require a 2 port LAG on the 48 port (for speed), and a 3rd port for the 24 port (for redundancy).
NOTE: With any luck, we'll be dropping our analog phone system and replacing it with VOIP sometime within the next year. So I should be getting some extra budget to replace the distribution switches with POE. Until then, I'll have to live with my crappy Planets.

We have a HP Procurve 5412zl switch as our default gateway for all our VLANs from there the traffic will be going to a Cisco ASA 5515 and then to a Cisco 3800 Router then to our ISP.
We have yet to purchase the ASA but my question is about my future configuration. I will have the router of last resort on the 5412zl setup to point to the ASA inside interface, how does that work with multiple VLANs? For instance the ASA inside interface would be 10.0.0.1 but traffic could come from another VLAN via the switch with a 192.168.1.x address. Would the ASA just pass it on to the router? Or would it conside this spoofing and drop the packet?
Lastely, if we have WCCP set for the ASA's inside interface, how would it handle the redirect for multiple VLANs ip addresses? Would I use GRE for the redirect to my web filter?

Is it possible to obtain a replacement rackmount kit for a 2960 48 port switch? I've had a read of the manuals but can't see a part number specified. The part number suggested to me (by BT) is for the 8 port version, which is not much use.

I wanted to know if I can somehow setup my network to use a proxy for all connected devices?
For example I can go into Firefox proxy settings and setup to browse using proxy. Is there any way to do this at the router or switch level to not have to configure every device individually I have a wndr3700 router and a HP procurve 1810g switch and am thinking of building a pfsense box.

I have a situation where two of my CGS-2520-16S-8PC switches are not applying POE power to the copper ports, but showing power inline, two ports are showing power applied. Shutting down the port and re-enabling it will return the port to normal and the phone will connect.
I'm running cgs2520-lanbasek9-mz.122-58.EY2 after using 122-58-se1. Happening on both, but i have more switches running EY2 with no issues at the moment. Using DC power supply averaging around 53v.

Unfortunately I do not remember the model and the switch is a couple of hours away without remote access.I have 4 vlans on a procurve switch.
VLAN1 - Network Devices (Server, printers, WAPs)
VLAN100 - Admin (Office workers)
VLAN200 - Teachers
VLAN300 - Students
There is a server doing DHCP. There are 4 ranges of IPs 1 for each VLAN.
The router is on Port 44. VLAN 1, 100, 200, 300 - Tagged
The Server is on Port 46. VLAN 1 - Untagged
The WAPs are on Ports 1, 11, 31 VLAN 1, 100, 200, 300 - Tagged
All other ports are on VLANs 100, 200 or 300 - Untagged
The WAPs all have VLANs 100, 200, 300. Each VLAN on a different SSID.
I have IP helper with the server IP on VLANs 100, 200, 300.
There are IPs from the different subnets on their respective VLANs in the switch.
The gateway for each subnet is on a different subinterface on the router.
The router is a linux box. (Untangle)
The WAPs are not able to talk to the server, therefore no computers on the wireless networks can get an IP.The server can only talk to the router if I change port 44 to untagged.What combination of tagged and untagged ports do I need to make everything talk?
Do I need to put the VLANs on the subinterfaces of the router?

We have two publicly routable gateways attached to our A5500 switch that are expecting untagged traffic.
We currently have VLAN 10 as the untagged VLAN for Gateway 1, and VLAN30 as a tagged vlan for Gateway 2. Since both gateways are requiring untagged traffic, I need to make sure all ingress traffic from Gateway 2 gets tagged as VLAN30, while all egress traffic gets untagged.
The tricky part is they must come over the same port so I can't just tag it that way. I get the feeling this will require some static routes or VLAN Interfaces on the switch, but I'm not sure where to start.

I have 2 procurve switches
2848
2650
Procurve stacking? Is that just a way too manage both switches together?
Or is it for combining both switches together?
Or is that called something else in procurve speak?
Or is that feature not actually available etc?
Next to learn how to breakup the 2848 into multiple switches.

I'm trying to configure Hp1810-24G and pfsense firewall with no success. I' would like to create two virtual lan on swich which share same internet connection. To simplifing I suppose
vlan 2 port 1-12
vlan 3 port 13-23
port 24 pfsense lan connection
What altready I do on pfsense I create vlan 2 called 1STVLAN VPID 2 and vlan 3 called 2NDVLAN VPID and assigned to them to LAN pfsense real port enabled and gived a static ip to them on HP procure I create two vlan with
vlan 2 port 1-12 untaged 13-23 Excluded 24 tagged
vlan 3 port 1-12 exluded 13-23 untagged 24 tagged
the problem is that I don't be able to speak with pfesense (ping failed on real lan ip and virtual lan ips) so I don't have also internet connection.The ethernet card i'm using are old (i have built the pfesense computer on spare parts that I have at home) so can be a driver issue?

So we recently moved our Comcast demarc to our new server room which resulted in moving the SMC modem from our old server room where it directly connects to the firewall - to a new room where it connects to a 2910 switch, LACP to our L3 switch, LACP to another 2910, then to Sonicwall.
Since the move our internet has been dropping off randomly for about 2-5 minutes then it will come back online. This happens anywhere from 10 to 50 times a day. Sometimes it happens a half hour apart, sometimes it is 15 minutes apart, sometimes it will go 8 hours without issue.
The modem has been replaced, the Comcast line has been "tested."
The modem remains online when we lose internet connectivity - I can connect to it using a laptop on it's lan port and ping out to google.com while an computer connected beyond the switch and sonicwall cannot connect.
I have run a constant ping from a home comptuer to the modem as well as to our sonicwall (both static addresses) and they both seem to go offline when we lose internet connectivity.
Since the issue started, I moved the Sonicwall so that it connects directly to the 2910 that the modem connects to, put it in a vlan with the modem so they only talk to each other and it still results in the same intermittent disconnects. I checked all the port statistics on both ports as well as the event logs, and trunk links and find nothing abnormal.
I take the switch out entirely and plug the modem directly into the firewall like it was prior to the whole move. Works fine.
Traffic is not an issue and the switch in question also connects all my production servers and iSCSI SAN together without issue.

I have:
-Procurve 1810-24G
-Procurve 2520-8-PoE
Router (with Internet Connection) is plugged into port 24 of the 1810.My asterisk server is plugged into Port 1 of the 1810.The 2520 is plugged into Port 2 of the 1810, and all of the VoIP phones are plugged into the 2520.Rest of the office computers are plugged into the remaining ports on the 1810.
After setting up the subnet and assigning an ip to the 1810, everything else just worked out of the box. I would imagine that I should segment and prioritize the network so that the VOIP traffic is isolated and is higher priority from everything else.
I tried playing around a bit, but the phones lost connectivity, so I just defaulted everything back for now.
What would the suggestions be for setting up the VLANS properly to do this?I would also need one of the office PC's (say the one plugged into port 13 of the 1810) to be able to access the asterisk server.Also, would it be more optimal to have the asterisk server on the PoE switch or the main switch?

I work as Network administrator in a building products plant at Poland. We had core switch HP Procurve 6200yl with 5 vlans, and 11 Aironet 1240AG Access points without controller. I have a problem with create 2 wi-fi VLANs on the Cisco AP's and linked it with HP switch.
VLANs on the switch:
1 - Default (for office sutff) - working great,
2 - Production (for production stuff) - working great,
3 - Inter (for Router's) - working great,
4 - WMS - i need configure it as wireless,
5 - WiFi with Radius - i need configure it as wireless.VLANS on the Access Points:
4 - WMS - for warehouse terminals - WPA2,
5 - WiFi for office stuff with Radius.
I'm easily able to get it running a single SSID (non-VLAN) network and confirm that I can use that network fine. However, I need to set up these 2 VLANs. I can connect to it via telnet if that'll let me program it faster.

I am having difficulties implementing Mac-auth on selected ports between an HP ProCurve 2510 and Cisco ACS 5.3.The 802.1x works just fine, but for selected ports I need to implement port-access with MAC-based authentication instead of regular 802.1X (yeah, I know, but this line of ProCurve switches only support one auth-mechanism per port!).The switch successfully forwards interesting MAC-auth requests for authentication to the ACS with CHAP/MD5, but the ACS reports this:
Logged At:
April 16,2012 1:20:48.080 PM
RADIUS Status:
Authentication failed : 22056 Subject not found in the applicable identity store(s). NAS Failure:

I have a HP Procurve 5406 connected to a Cisco 3560 on a temporary cat5e connection and I have Mitel IP phones needing to go on the Cisco switch.Ive configured the HP Procurve port to TAGGING both VLAN 10 (data) and VLAN 20 (Voice). NO is selected for default VLAN 1.The Cisco is configured on the port with switchport encap dot1q and switchport mode trunk.
Ive configured an IP for interface VLAN 10 and i cannot ping it from across the network. The interfaces are up and happy. I have tried changing the VTP status from transparent to server (VTP pruning is off) ive tried setting allowed vlans 10,20. Still not a think. The worse thing is that i have a working Cisco switch with the HP procurve that i checked the config on and its the same! The only difference is that the media type is SX over SFP in that case.
p.s not that im at this stage yet but i initially configure the FastE ports as trunks with native vlans because i was using non-cisco phones. On a spare port i convigured the voice vlan 20 and i say on the mitel phone that it was looking on vlan20! I didnt expect that, i thought the Voice VLAN ID was carried on CDP enabled devices only.

DLINK RMA service is worst I have ever experienced.I sent my defective DLINK DIR-655 router to RMA department about 3 weeks ago, and finally got the replacement today. However, can you believe the replacement from RMA is also defective, not connecting Internet at all? After spending about 1 hour with technical support again to confirm the replacement is still defective, I was told to request another RMA. Should DLINK expect me to spend another $10 shipping fee and wait for another 3 week for another replacement because of a mistake made by DLINK RMA service?

The issue im having is that i have recently had no issue with the wireless network. But today my laptops battery would not charge and as a result the computer died. I had to remove it to get it to charge again. Since then i have been unable to connect wirelessly to the network it simply says "windows is unable to connect" I have however been able to get online using an ethernet cable on the same router.ive looked around on varius forms but no information has assisted thus far.

I have a side gig that I do some work for and they've had a Sonicwall TZ200 device in their branch office and also in their data center that has a site to site VPN connection between the two devices. About a month ago the bandwidth throughput got severly decreased. They went from getting about 28Mbps/27Mbps to now ~3Mbps/12Mbps.
I've spent days troubleshooting with Sonicwall which could be a whole dedicated thread on it's own but I digress. I even had the ISP come out and test the line and when they hooked up their own laptop it got the speeds it should be getting. I've rebuilt the config on the sonicwall from scratch which was a major pain in the ass because I'm not a firewall guy by any means. After firmware updates and pulling my hair out I've decided to dump the tz200, to what I don't know. I need two devices, one for the data center and one for the branch office. I'm pretty sure something in the config is causing this and after being escalated to the highest level at sonicwall and them sending me a replacement unit which I rebuilt the config on and also tried to import the old settings with no luck. I very well could have done something or made a change to cause this but I'm at a loss and willing to try another product.
I get spammed from Barracuda all the time, do they have quality devices? Something with a web interface would be great since I'm not a firewall guru by any means and had set up a bunch of address objects with NATs and all that.

For our client, we have two ACS 5.0 deployed in primary and secondary mode.Primary ACS is failed and we are going to replace the hardware.Problem is we dont have backup of primary ACS and have backup of only secondary ACS.Also there is certificate used for authentication of wireless users.In this case how we can proceed for for the restore.
If we promote secondary ACS to primary and join the New ACS as secondary,will the certificate also synchronised? or we need to create CSR and obtain the certificate for new ACS?
