Can HP1950 be managed by Airwave and is it a good replacement for SG500X

Hello everyone,

we are to deploy an Aruba wireless solution for a customer. They told us they had SG300 switches (8 of them) with no PoE. We have decided to replace those switches with HPE1950. It came out that they have 2 stacks of SG500X with 10GbE stacking modules.  I am wondering, if there is really a need to replace those switches at all.

1950 seems to have:

half of the packet buffer SG500 has

IRF stacking (altough not mentioned directly); so comparable to Cisco (at least I think so)

similiar switching/forwarding performance, similiar features

liftetime warranty

and they can have a few bucks back by selling their switches along with stacking modules and getting a new solution with warranty. Are there any other important technical information that could affect such a comparison? This is question number one.

The reason the would do such a exchange is central management system.  That also leads to a question numer two. As they can not afford switches from provision line that has a full Airwave support, how will the HPE1950 line work with Airwave? What will we able to do: nothing, see switch status, backup configurations or manage the switch?

I chime in regarding your second question: AirWave 8.2.3 supports HPE OfficeConnect 1950 Switch Series.

Directly from AirWave 8.2.3 Supported Infrastructure Devices (Chapter 3):

"HPE Devices

Aruba AirWave 8.2.3 introduces monitoring support for the following HPE Aruba switches running Comware 7, including monitoring, full template configuration (without requiring a reboot) and partial template configuration:

  • HPE 1950 Switch (Aruba validated and fully supported Software Version R2220P02 [*] but current software version is really part of R31 branch, R3115P03)
  • HPE 3100 Switch Series
  • HPE 3600 Switch Series
  • HPE 5120 Switch
  • HPE 5130 Switch
  • HPE 5500 Switch Series
  • HPE 7500 Switch Series
  • HPE 10500 Switch Series"

[*] I do believe this is an Aruba documentation error since, AFAIK, the HPE OfficeConnect 1950 hadn't any R22xx software version published and its first software release ever published was the R3108P02 (so R31 branch).

hpe 1920 VLAN's for dummies

I am in need of some assistance / advice regarding a basic setup of a vlan on an hpe1920 - I have inherited a site with a pair of 1920's - currently connected to a network using a Draytek firewall router for inet access etc, this is confogured on class c (192.xxx) - seperate to this, but sited right next to one of the 1920's by the comms cabinet is another network, used predominantly for wifi consisting of an Apple Airport extreme and 5 Apple Airport Express's used as AP's - the express's are patched to an 8 port unmanaged hub which is connected to the AAE, this network is configured using Apple default class a (10.xxx) settings - so - given that networking is not my area and HP switches even more of a mystery to me - the client wants to retain the seperate Draytek and Apple inet connections (to keep the ethernet and wifi users seperate) but without getting to clever could I not just in effect remove the unmanaged hub by creating a vlan of say 8 ports on the 1920 and patch the Apple Express's and the Extreme router to that vlan - is that sensible/correct and if so how do I do that on the 1920?

Any assistance advice/pointers etc welcome.

 

Thanks

I am having difficulty with establishing a fiber connection between two Pro-Curve switchs.  At one end is a 1410-24G and the other end is a 1920-8G.  Each switch has a J4859C transceiver installed. fiber installer verifies the terminations but I cannot get the switches to connect.  The run is only about 450 feet.

Any suggestions?

Thanks

OK, the J4859C transceiver module (namely HPE X121 1G SFP LC LX Transceiver) is supported on both Switch series (HPE OfficeConnect 1920 and HPE OfficeConnect 1410) so IF both used transceiver modules are HP/HPE genuine you should be OK.

A Note, to be precise: both Switch you are using AREN'T HP ProCurve...they belongs to the HPE OfficeConnect family, they don't belong to ProCurve (now Aruba) family...consider that the 1410 is (or looks) unmanaged (If I were you I would go for another 1920 instead).

If both modules are HP/HPE genuine you should be able to identify them on each Switch's GUI. Is that true?

If that is true then you should be also able to configure the physical port into which you physically installed them respectively on each Switch unit (pay attention to Combo - AKA Dual Personality - ports: if you use the Copper Ethernet you can't use the Transceiver and vice-versa): is that true?

If that is true (configuration is possible or, if you leave all port values to default, it is at least verifiable on port status/port details) you should be OK and the inter-switch link should "lights up" (on both ends). Setting the Port Type of Type Trunk for involved ports then would be better.

Optical link end-to-end (I mean from each Transceiver to each Transcevier, passing through Optical Patch cables and Optical Patch Panels on both ends) should be cabled accordingly (see, just as example, here).

Is it possible to disable the management features of the HP 1800-24G J9028B? We wish to use it as a dumb switch for external internet connection purposes. I don't think there is a way but thought I'd ask the group. Thanks!

What management feature hurts you exactly?

The fact a Switch is (Smart-/Fully-)Manageable doesn't necessarily mean that must be managed in all its aspects (well, that's very basic, at least provide it with a IP static addressing and a Default Gateway...that's for management purposes only and let it - if it supports that feature - to synchronize with an external NTP Server...or provide an internal NTP Server if your network has one...so Switch generated logs are collected with corrected date/time): it can act as a "dumb" switch too...if no management is done at all.

The only thing you should care of - at this point - is to avoid to release (Web-/SSH-/Telnet- if active) login credentials to other non administrative IT operators you don't trust (yourself excluded).

Hello everyone, actually I use 1810-24 switches with X111 SFP, 100 FX moduls  (model J9054C)
Now I want to buy 1420-24 switches and I can't find any informations about compatibility with the X111 modul

Can someone tell me if 1420 switch and X111 modul are compatible ?

thank you !

If you are going to purchase HPE OfficeConnect 1420-24G 2SFP (JH017A) switches, the HPE 1420 Switch Series QuickSpecs reports (see here) only these SFP Transceivers:

  • HPE X121 1G SFP LC SX Transceiver (J4858C)
  • HPE X121 1G SFP LC LX Transceiver (J4859C)
  • HPE X121 1G SFP RJ45 T Transceiver (J8177C)
  • HPE X120 1G SFP RJ45 T Transceiver (JD089B)
  • HPE X120 1G SFP LC SX Transceiver (JD118B)
  • HPE X120 1G SFP LC LX Transceiver (JD119B)

as supported.

So, if your plan is to use the existing Fiber Optic uplink (is it a long - more than 550 meters - run?), the most proper supported Transceiver types should be HPE X121 1G SFP LC LX Transceiver (J4859C) or HPE X120 1G SFP LC LX Transceiver (JD119B).

Note the LX (that's for cable length up to 10 km).

If you have other requirements (a short run, let's say below 550 meters) maybe a SX (generally with a 850 nm central wavelenght) type should suffice.

Consider that both J4859C and JD119B have:

  • Connector Type: LC
  • Central Wavelength: 1310 nm
  • Multi-Mode maximum distance: 550 meters
  • Single-Mode maximum distance: 10000 meters (10 km)

So the SFP Transceiver selection boils down to what type (especially its length and its mode) of Fiber Optic uplink you have to reconnect to.

HP 192048G VLAN

Hi, i have 4 Switch HPE 192048G and 3 vlans, i would like to setup this way:

#1 - port 1 - 36 access tagged VLAN1 / port 37 - 47 access tagged VLAN2 / port 48 - 52 trunk tagged vlan1,2,3 switches interconnection (router of network VLAN1 interface untagged in port 1 - router of network VLAN2 interface untagged port 37)

#2 - port 1 - 47 access tagged VLAN1 / port 48 - 52 trunk tagged vlan1,2,3 switches interconnection

#3 - port 1 - 36 access tagged VLAN3 / port 37 - 47 access tagged VLAN2 / port 48 - 52 trunk tagged vlan1,2,3 switches interconnection

#4 - port 1 - 46 access tagged VLAN1 / port 47 access tagged VLAN2 / port 48 - 52 trunk tagged vlan1,2,3 switches interconnection

Is the configuration right? what is the difference to set a port (in my case any port is a member only of a single vlan) to set the ports as tagged?

can i set the management ip of switches on vlan2? as the switch 3 have no VLAN1

Thanks.

V1820-48G Web Interface goes down, stays down until reboot

We've been having some trouble where intermittantly, the web interface for our V1820-48G switches will become unreachable. After power cycling the switch access to the web interface is restored.

While researching this I found information about CR_0000105424 which was basically the same type of fix but for the V1810's. In an attempt to resolve this issue I have updated to the firmware to the latest release, PT.01.14, but it has not resolved the issue.

Does anyone know of a durable fix to resolve this issue? 

Thanks!

Hi, the HPE OfficeConnect 1820 48G Switch correct Product Number is J9981A (not J9981!).

Have a look at HPE OfficeConnect 1820 48G Switch Series QuickSpecs published here, at Page 7 you will find the "Note 1", there you will see supported genuine HPE Transceivers, actually:

  • HPE X121 1G SFP LC SX Transceiver (J4858C)<-- that's the one you should use.
  • HPE X121 1G SFP LC LX Transceiver (J4859C)
  • HPE X111 100M SFP LC FX Transceiver (J9054C)
  • HPE X121 1G SFP RJ45 T Transceiver (J8177C)

Keep in mind also that these Transceivers:

  • J8177B
  • J4858B
  • J4859B
  • J4860B
  • J4860C
  • J9142B
  • J9143B

are NOT supported by the HPE OfficeConnect 1820 Switch Series (no matter which software version the Switch is running), references here and here.

Be cautious in using non genuine HP Transceivers (declared as "compatible") as the one mentioned (A7446B).

JE005A downgrade from 1910_5.20.R1513P98

Hello! I have two JE005A Hardware Version is REV.B and one of them being upgraded to 1910_5.20.R1513P98 (default was 1910_5.20.R1111P02). Now i cannot access to web interface by http+firefox, while another JE005A with old firmware is available. When i try downgrade, it returns error:

Failed to upgrade software.
Error in setting boot file.

 

My questions is:

  • Whether 5.20.R15 versions of firmware compatible with my JE005A? If not:
  • How can i downgrade to 5.20.R11?

Why you upgraded to Comware 5.20 R1513P98 (released 30/05/2015) when, actually, the latest compatible software version for JE005A is Comware 5.20 R1518P01 (released 29/06/2016)?

I can't understand why you upgraded from a very old version (R1111P02 of 19/06/2012) to another old version (R1513P98 of 30/05/2015) without considering the very latest available (R1518P01 of 29/06/2016)?

JE005A (HP 1910-16G or 3Com Baseline Plus Switch 2920) supports R1518P01 and, if you read the HP 1910 Comware 5.20 R1518P01 Release Notes, you will discover about restrictions and upgrade/downgrade guidelines (Page 5): as example (Page 7), once you upgraded to R1513P98, so after R1513P62, for sure the Switch BootROM was automatically upgraded too to - say - version 163 (please verify your BootROM version, it could be newer [*] than 163)...so a subsequent downgrade to a software version earlier than R1513P62 cannot be done.

[*] Consider that R1518P01 upgrades the BootROM version to 178...

How to delay the mac-based authentication

January 15, 2017, 7:59 pm

I want to configure ports for 802.1x authentication with MAC based authentication as fallback. My problem is that, as soon as I plug in my laptop, the switch will use my MAC address for authentication, without giving me a chance to put in username and password on my laptop (Win7 pro) for PEAP.

My laptop is configured to prompt for username and password.. I can still put in the username and password in the popup balloon. Once provided, the switch will still do the 802.1x. However it will fail the first MAC authentication, and the laptop will be put in a wrong VLAN, with the wrong IP, before the followed 802.1x to correct the vlan and IP. 

Is there anyway to delay the MAC auth? For example, always wait for 10 seconds before trying to use MAC for authentication. I am able to tune the timers on Cisco switches. 

I have tried a few timers but none helped my case. Here is my config. Thanks!

 

radius-server host a.b.c.d key "xxx" acct-port 1813 auth-port 1812
aaa server-group radius "1X" host a.b.c.d
aaa accounting network start-stop radius server-group 1X
aaa authentication port-access eap-radius server-group 1X
aaa authentication mac-based chap-radius server-group 1X
aaa port-access authenticator 23
aaa port-access authenticator 23 client-limit 2
aaa port-access authenticator active
aaa port-access mac-based 23
aaa port-access mac-based 23 unauth-vid 1050

 Forgot to mention that my swith is HP J9727A 2920-24G-PoE+ with WB.16.02.0014
