Re: 802.1X on HPE 1950

I upgraded the firmware to 3116, but I still get the same behavior.  802.1X does not authenticate and does not prompt for authentication.  The logs on the RADIUS server do not show any entries for 802.1X authentication or for the HPE 1950.

Cryptic error message HP V1810-48G

Every few months I receive error messages through syslog from one of our three switches (firmware PK 1.34) like this:

[-2131330512]: hal_misc.c(96) 1523 %% Jump to NULL! Interrupt: 0x00000000  vector: 0x00000098  cause: 0x00000000  status: 0x00000000

 

So far I see not a real impact..

Can anyone say anything more about these errors?

Just speculating (I'm not an embedded system developer): HAL_misc.c would refer to miscellaneous function(s) provided by Hardware Abstraction Layer (HAL contains all start-up code) by means of a C source code that should be part of the embedded OS (eCOS operating system based? like  eCos-2.0, CFE-3.8...or something similar)...so it's definitely something related to embedded operating system running on HP ProCurve V1810-48G Switch...and the HAL_misc.c routing is outputting an exception ("Jump to NULL!"), the culprit? I've no idea...better to infrom HPE Support by opening a Ticket since you're running a very latest software release (PK 1.34).

Read here ("3.1 Exceptions") and two interesting instructive hacking references here (Take 1) and here (Take 2).

Trunking GBIC ports in Procuve 1810G-24

I have several ProCurve 1810G-24 switches I want to link via fiber. with GBIC's inststalled each port (23 or 24) communicates with the other switch. As soon as I make either port part of a trunk is stops communicating. Is there a setting I am missing? I can make trunks with other ports but not the fiber ports.

Thanks

On J9450A SFP Slots 23S and 24S can't be used CONCURRENTLY with RJ45 Ports 23T and 24T: or the RJ45 ones or the SFP ones, not together (either/or)...so if you're using 23T then 23S can't be used too, the same is valid for the pair 24T/24S...this restriction (a feature, from another point of view) is generally known as "Dual Personality" or "Combo" ports.

From the HP ProCurve 1810G-24 QuickSpecs:

"Dual-personality ports (1810G-24 switch): two 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH, or 100-FX"

So first of all check that Ports 23T and 24T aren't used (connected) if you're planning to use Slots 23S and 24S.

HP 1920 - 8G-PoE Radius Authentication Web limitations

Hello,

I have lots of 1920-8G-PoE  switch and I want to login these switches with my Windows 2016 NPS server. I can login many other switches which contain 2626, 2650, 2620, 2610, 5300 series, 5400 series, A5700, A7500 series with my NPS server.  I manage them without any problem and I use ssh for login these switches. HP 1920 series have some ssh limitations so I have to login with web interface. When I configure AAA and Radius options of these switches like the others, I see only Network --> diagnostic tools menu and its IPv4 Ping, IPv6 ping IPv4 Traceroute and IPv6 Traceroute submenus. I searched on internet, I found some information about HP 1920 NPS configuration https://www.reddit.com/r/networking/comments/4tnyaj/aaanps_with_procurve_19101920/d5k64mm/ 

but it doesn't work for me. I did firmware upgrade (Switch software version: 5.20.99 Release 1117)

Is there anyone to manage this issue?

Soner.

OC20 Management & Features

Hi,

we recently received information about the new APs for small environments HPE OfficeConnect 20.

The product sheets are looking promising for very small customers with up to 8 APs. But there are a few things, that are missing. I hope someone here can help me clarify them.

Are the APs able to use WPA2-Enterprise / 802.1X Authentication?
Doe the APs have a web management? I can only read about an app to use locally. The problem is, that we rarely are at our customers in person, when a problem in the wifi appears or when a change is needed.

Thanks!

Good question...latest QuickSpecs (04/09/2017) doesn't go further than saying WPA2 and Advanced Encryption. There is no reference about IEEE 802.1X.

Linkk wrote: Doe the APs have a web management?

Yes, it does.

From latest HPE OfficeConnect OC20 802.11ac Access Points Release Notes (3rd Edition, 18/09/2017):

"Access HPE OfficeConnect Wi-Fi Portal

The HPE OfficeConnect Wi-Fi Portal is available as a web application and also as a mobile app. You will be automatically signed up for HPE OfficeConnect Wi-Fi Portal when associating an email address to a site and if the same email address is not linked to another existing account. You can view the sign-up information by clicking the advanced menu icon in the web application and selecting Administration from the drop-down list.

The Administration page will display the sign-up information used for this account.

The HPE OfficeConnect Wi-Fi Portal app is supported both on iPhones and Android devices. You can download the HPE OfficeConnect Wi-Fi Portal app from the Apple App Store and the Google Play store."

indeed a list of supported Web Browsers is available to access the HPE OfficeConnect Wi-Fi Web Portal. As I read it, the HPE OfficeConnect Wi-Fi Portal App (now at version 1.2.0) is not strictly mandatory, just suggested.

Just got a J9984a, 1820-48g.  Brand new.  Setup a laptop with IP 192.168.1.2, 255.255.255.0.  Plugged directly into switch.

It looks like it connects, but it wont hit the login switch with 192.168.1.1

I did do a 15+ sec hard reset.  No avail.

Please advise.

I can ping it from a cmd window (192.168.1.1).

Cannot telnet either... says "permission denied".  Havent even been asked for a login.

Why do you think that Switch should have the Telnet server service enabled (if any at all)?

From what HPE OfficeConnect 1820 Switch Series Installation and Getting Started Guide (March 2017), it should fall back on default 192.168.1.1/24 IP Address if it doesn't found a valid DHCP Server releasing to it an alternative (or the same IP Address) in 120 seconds...so a question: do you have a device in the same LAN Segment and for the same Default VLAN that is acting as DHCP Server? if so...what is the IP Address released to the HPE OfficeConnect 1820 Switch (you should be able to verify that reading the DHCP Server Logs looking for the HPE Switch MAC Address).

I ask because you must be sure that the IP Address you're pinging and on which you believe there is the HPE Switch Web GUI is really that address (so DHCP presence matters).

If not, no DHCP Server is available, the Default 192.168.1.1/24 IP Address is valid (wait at least two minutes before connecting from Power On).

HPE OC20 802.11ac (RW) Access Point performance issues

We deployed two customer sites with HPE OC20 devices. Both started to have performance issues with wireless with these new OC20 devices. Transfer speeds especially with SMB transfer from Windows servers is horrible. Usually 5GB file transfers takes about 440 seconds. With other AC series devices it takes only 120-150 seconds. We tried upgrading the firmware and same issue. Did not help, when looking at the Windows 10 data transfer screen it only transfer files at 5MB/s speed. We are having this same issue now with 9 OC20 devices that are in two different sites. 

Anyone else having same issues? We have open case number with HPE also with this. We have tried different poe switches also, but same issue remains.

check switch default gateway address.

switch default gateway address must have your branch site router lan address...

Were Wireless hosts used to perform your transfer speed test [*] connected to the 2.4 GHz radio band IEEE 802.11n (Maximum theoretical throughput of 300 Mbps, more or less 30 MBps) or to the 5 GHz radio band IEEE 802.11ac (Maximum theoretical throughput of 867 Mbps, more or less 80 MBps)?

To me, an average file transfer speed (if there aren't other bottlenecks elsewhere on the wired side) of just 5 MBps looks like Wireless host is potentially using the IEEE 802.11g radio band at 2.4 GHz (Maximum theoretical throughput of 54 Mbps) or the radio signal is very weak/disturbed if the Wireless host is not in a good line of sight with the Wireless AP used for testing [**].

[*] For sure, better doing various iperf3 client/server tests between a Wireless host and a Wired host...

[**] That's to say that testing (and also planning) a Wireless network could be tricky, you have to consider all variables (Wireless hosts status, wired networking status, how to test, what to test, Wireless APs planning and deployment, avoiding radio interferences and improper APs positioning...it's complex)...clearly if you're testing just one or two APs well positioned, the Wireless host is well connected, Wireless NIC device driver is updated and properly configured, Wireless APs Software is updated, Wired side is OK (no evident bottlenecks)...and you measure bad performances...then there is a real issue.

Clients are connected at 5Ghz AC to OC20 if we check from client or from OC20. I have attached picture of that. I suggested to HPE ticket the 802.11g radio also, cause speed is so constant. Radio signal is pretty much perfect. We have now connected one OC20 to our lab and laptops are on same table not more then 1 meter away. 

I think this is real issue at the moment. As I said before we have now two sites with multiple OC20 devices and one OC20 in our lab and same issues in everyone.

Here is picture attached so you can see that even the OC20 management shows that clients are connected with 5Ghz bandwith.

Would be interesting to perform the same test you already did on the exact same wireless host using a Linux live distribution as host OS instead of Microsoft Windows 10 (provided that any very recent Linux live distribution should have the latest iwlwifi kernel driver for the Intel® Dual Band Wireless-AC 7265 NIC)...that's to isolate any potential issue caused by (or related to) a specific version of driver provided by Microsoft for its Windows 10 OS (aka: are you using latest Intel provided drivers for Windows 10 - it should be 19.70.0 - instead of Microsoft flavour of the same device driver superimposed via Windows update?).

 

Start checking from here (or directly here) if you can't test using a Live Linux distribution...

We have tried with different devices. OK, everyone has been with Windows 10. HP Zbook 14u G4, HP Elitebook 745 G4, Lenovo T470s, HP Zbook 17 G4 and HP Elitebook 840 G4 are the laptops that we have tested. Same results with everyone, currently we don't have any devices with Linux, but we have one Macbook Air that I could try also

Yeah, to test the Wireless device behaviour under Linux (once you checked the Windows device driver side) you don't need to install anything on your laptops...a Live Linux distribution - as example you can try Fedora 26 Desktop Live with XFCE here - doesn't require to install anything, you can easily try it just booting from a DVD or USB stick (follow instructions on how to create a bootable DVD/USB from downloaded images).
