Hi,
In HP 1920/1950 switch brochure, it shows it can stack up to 4 units. I'd like to know it can be combined to form a single logical switch with at least 2 units or not. I'd like to provide high resilent switch to connect with two NIC(to form a teaming) on server/hypervisor. As I know, the IRF (to form single logical switch) is supported on high-end model such as 5500 series.
Any ideas, please share us.
Thanks.
Hi all,
In the past, I worked with HP 1810 24G switches and my system works properly.
Now I'm going to migrate HP 1820 24G switches, but I discover a little problem in my application, this is my scenario:
I have to connect two sites (site A and site B) throght 2 different phisical links, so, I place 1 switch x site and I configured
them as follow:
Site A and Site B has the same configurations:
port 1 to port 2 as part of trunk 1.
port 3 to port 12 as part of VLAN2 untagged
port 13 to port 26 as part of VLAN1 untagged
trunk1 as part of VLAN1 and VLAN2 Tagged
Trunk 1 = dynamic mode
spanning tree enable as RSTP
Now I connect two phisical links (radio links) between Port 1 site A to Port 1 site B nad between Port 2 site A and Port 2 site B.
The sistem seems to works properly but, if one of the radio link goes down, the connection between site A to site B goes down for about 90 seconds and then go UP.
I think that the problem is someting about the the algoritm used from the trunk to switch from one port to another, but I don't found a solution.
With the HP 1810 24 G the switching time was about 5 seconds!!!!.
Can anyone help me?
Tanks and exuseme for my english.
Dear HP Team,
The latest Firmware for "HP 1920-48G Switch JG927A" is "5.20.99 Release 1107" which only supports sslv3.
Chrome AND Firefox 40.0.3 wont allow any connection to the webconfigurator, since sslv3 is very vulnerable.
will there be an upgrade for the SSL Protocol used for the webconfigurator? Is there any workaround?
Hello everybody, here 'Levin' from holland.
Today we bought the HP Switch 1810-24 v2. We hooked it on and we've noticed that our apple iMac's didn't connect true the hp switch. What seems that our manual configuration in the ethernet settings with :
1000baseT
Full-duplex
MTU: Standard 1500
AVB/EAV Mode enabled
Won't work????? So we put them back to 100baseT
But how come??? Does anybody knows how to fix this?? Sorry for my englisch writing, im from the netherlands.
(funny thing is, we have here a very old, old, old, very old Micronet Fast Gigabit Ethernet Switch 8-ports, working perfect)
Or did we buy the wrong one??? Can please somebody tell me what is wrong...
We have printers with 10/100Mbps and our iMacs with 100/1000Mbps, but now the 1000 won't work with this switch?
Greetings Levin den Boer.
Hello.
I have issue with setting up of HP1910-48 (JG540A).
When I tried to configure VLAN other then ID=1 (for example 100) I had problem because I can’t transfer TCP packets over this VLAN.
What I meaned:
1. I run web console and select Network-VLAN
2. Create new VLAN with number 100
3. Select some ports and assign to this VLAN (All ports Untagged, of course)
4. Check configuration.
Then I connect to this ports (with new VLAN) three devices: other switch, one computer and one notebook.
So, computer can ping notebook but can’t ping devices behind other switch.
BUT, when I set for all ports default 1 VLAN - all works fine.
Any ideas?
Vlan routing : can't access internet.
Hi ,
I need some help on this issue that is making me mad …
On my switch 1910-8G , I can create VLANs and make routing between them . Each PC in a vlan can ping another PC in another vlan
But a PC in a Vlan can't go on the internet excepting PC in default Vlan
Here is the details :
Switch HP 1910-8G JG348A , version 5,20 release : 1513P99 BootRom 173
Network schema :
Internet Box access : Lan 192,168,1,254 /255,255,255,0 , WAN Fix IP by Internet provider
|
Router : Lan : 192.168.0.254/255.255.255.0 , Wan 192.168.1.253/255.255.255.0 gw 192.168.1.254 on port 8 of the switch default vlan 1
|
|
Switch configured with network wizard : I give it : 192.168.0.253 / 255.255.255.0 and gw : 192.168.0.254
so it create a default IP V4 route : 0.0.0.0 / 0.0.0.0 / Nexthop192.168.0.254 Vlan Interfave 1
I created VLAN 30 and make untagged member Port 3 , and not member from VLAN 1
I created VLAN 40 and make untagged member Port 4 , and not member from VLAN 1
I create virtual vlan interface 30 : 192.168.30.254/255.255.255.0
I create virtual vlan interface 40 : 192.168.40.254/255.255.255.0
PC0 : 192.168.0.11/255.255.255.0 gw 192.168.0.253 on port 1 PVID 1
PC30 : 192.168.30.11/255.255.255.0 gw 192.168.30.254 on port 3 PVID 30
PC40 : 192.168.40.11/255.255.255.0 gw 192.168.30.254 on port 4 PVID 40
ping works in all ways between pc
PC0 can go on the internet and ping 8.8.8.8 and 192.168.1.254
PC30 & PC40 can't go on internet and can't ping 8.8.8.8. or even 192.168.1.254
Adding route 192.168.30.0/255.255.255.0 gw 192.168.0.253 in Internet Router (DD-WRT) helps PC30 to ping 192.168.0.254
Please note that I have already delete 0.0.0.0 / 0.0.0.0 / Nexthop192.168.0.254 Vlan Interfave 1 created by wizard and recreate it manually (instead with the wizard option) and there was no changes .
I didn't define any ACL. The configuration is done after a switch re-initialization .
Same result with port in Hybrid or in Access mode …
Aaaarrrgghhhh ! ;-)
What am i missing ? Thanks for your help !

Good day, I have several new 1810-24G switches. We were told by Vonage Business that we need to remove all the managed switches and move to un-managed switches. I read an article that you can change the switch into a Pass-Thru Mode? I can't just remove all the switches. We having dropped calls but the ISP (2 different ISPs) show that their data is as good as its going to get. My next solution is either the switches or our Sonic Walls.
THanks for your help.

Hello,
I have two HP1920-48G configured with some VLANs and today I have an odd problem.
If I try to change a port configuration (for example to move from acces to hybrid port) the web gui log me out.
I've tried to restore the configuration backup, to reboot, to delete and recreate the VLANs nothing work.
Some suggestions?
Thank you.
Locking down HTTP, HTTPS, and Telnet are pretty straight forard... Not really seeing how one can lock down SSH though - can anyone help?
Right now i have 2 vlans on the switch - one (VLAN1) is for management and the other (VLAN2) is for our wireless network. Both VLANs have an IP on them, but i'd like to prevent IPS from VLAN to to be able to hit the VLAN 2 IP with an SSH connection.
The ACL i created for HTTP/HTTPS/Telnet seems to be doing the trick - how can i apply it to SSH too?
Thanks,
Chris
Hello,
I have been having a consistent issue for quite some time now with my 1810-24G V2. After a short perios of time (a few hours to a couple of days), the Web Management UI becomes unavailable. The only solution is to go to the rack, pull the power on the unit and have it reboot. At that time, the switch's Web Management comes back up. Lately, this has been causing a huge issue.
The switch is running firmware PL.2.04 on both images. Here is the system description line:
HP 1810-24G, PL.2.04, eCos-3.0, 1_12_8-customized-h
Any ideas on how to resolve this issue? From researching it, it looked like it was supposed to be resolved in code 1.17. Clearly, for my model, this is not the case.
Any help is GREATLY appreciated!
Hello,
I am a happy user of several 1910-24G-PoE+.
I can't see 1910 series on HP website anymore, so I assume they have been discontinued.
From the 1920 series description, it seems that they are 1910 successors. Am I right?
Apart from the terrible comments regarding VLAN routing performance because of ARP table problems and non-existing support, I wanted to ask if 1920s are configuration compatible with 1910s, as it seems there is a 1-to-1 correspondance in the series' models.
Let's hope the existing issues will be addressed by HP with future firmwares, and the 1920 series will be as good as 1910.
Hi folks,
I'm new to this forum and HP's 1920 switching technology.
What I'd like to do is getting a 1920 configured with 2 VLANs (intranet and adminnet), but with WebLoing enaböed in only one (adminnet) of them.
So far I configured the 1920 with two port based VLANs and assigned one static adddress to each.
I'm performing the routing between these two VLANs by a seperate firewall which works fine for me.
My problem this in the Web GUI's wizzard in the "Management IP Interface Configure" I can configure one IP address for each VLAN. But, when I changethe "Admin Status" from "Up" to "Down it works for both interfaces instead of just one and I kicked out myself from the WebGUI. How can I get this configuration running using just one of these Management IP Interfaces?
I tried to revoke/change my selection via serial console, "_cmdline-mode on" and "SYS". There are a lot of CLI commands available, but sadly not documentation available on the web. Searched 4 hours now using Google and gave up. Just old ProCurve CLI documentations are available, using "enable" and "config" mode (I know form former times ... and from CISCO routers).
But, back to my inital question: How can I configure the 1920 for 2 port based VLANs using only interface in one VLAN for WebLogin?
Any ideas, hints, etc.?
Thanks in advance and greetinx

I have a new HP 1920 48G Poe+ Switch. I am using it for VOIP. All of the ports are providing power and networking except for 6. They are ports 41 throough 48... If I plug a phone in I get power. But, I get no network. I have taken a test phone and plugged it into the ports and this behaviour occurs. If I plug the phone into another port I get both power and networking. I have no VLAN's configured.
Any thoughts?
We are trying to implement vlan on several 1920-24G switches, but I think we are seeing inter-vlan routing issue.
Here is the set up (since there is no useful cli output, I have to be wordy):
We have a default subnet in 192.168.100.0/24, we have some ports untag as 50 on several switches' select ports, so that PC connecting to these ports will be on 192.168.50.0/24 subnet.
All the switches involved have VLAN Interface configured in both 100.0/24 and 50.0/24 subnet. The network is in star topography:
a) Star center:
default gateway: 192.168.100.237 (this is our firewall IP)
vlan interface: 192.168.100.4/24 | 192.168.50.1/24
IPv4 routing (mostly created by VLAN Interface create):
destination mask protocol priority Next Hop Interface
0.0.0.0 0.0.0.0 static 60 192.168.100.237 Vlan-interface1
127.0.0.0 255.0.0.0 direct 0 127.0.0.1 InLoopBack0
127.0.0.1 255.255.255.255 direct 0 127.0.0.1 InLoopBack0
192.168.50.0 255.255.255.0 direct 0 192.168.50.1 Vlan-interface50
192.168.50.1 255.255.255.255 direct 0 127.0.0.1 InLoopBack0
192.168.100.0 255.255.255.0 direct 0 192.168.100.4 Vlan-interface1
192.168.100.4 255.255.255.255 direct 0 127.0.0.1 InLoopBack0
b) All satelites (total 5 of them):
default gateway: 192.168.100.4 (the IP of the star switch)
vlan interface: 192.168.100.xxx/24 | 192.168.50.yyy/24
The IPv4 routing is similar to above, except the default gateway line:
destination mask protocol priority Next Hop Interface
0.0.0.0 0.0.0.0 static 60 192.168.100.4 Vlan-interface1
We have no other QoS configured.
The initial implementation is half success, we have no issue between devices within 192.168.100.0/24, or within 192.168.50.0/24 subnet.
The pinging between the 2 subnets, however, show some packet dropping, anywhere from 0% - 20% loss.
What could be the issue here?
Hello All,
We just purchased one 1920-24G 370W and three 1920-8G 180W. The eight port switches work fine but the 24 port model seems to have an issue. When we plugged our first PoE device all of the PoE lights started alternate flashing from side to side. I have updated the firmware and reset the device. The error persists and now happens on cold and warm boots with no copper plugged in. Communication on non-PoE works even when the PoE lights flash.
In the PoE options it says "off" for PSE status. All screenshots I can find suggest this should be on. This option does not appear related to the compatibility mode as that is listed separately. The status page never shows any fault or overload: Only enabled or disabled depending on what I try.
I suspect the switch has a problem I need to request an exchange for but due to the lack of documentation it's completely possible I am missing something. I greatly appreciate if anyone recognizes this. I searched but did not see anything at least in this sub forum.
I say the error code is "undocumented" in that this situation is not mentioned in any documentation I can get ahold of. I have to say that between the broken links, random very slow page loads, difficulty finding documents or firmware and difficulty finding support pages I will probably not purchase HP products of any kind again. This is an issue I've had over the years but it's much worse since the split of HP and HPE. It's really a shame since the products themselves are quite nice. Please pardon the rant.
I just received a nasty surprise earlier today. I recently purchaased a 1820 switch to add to a group of 1800s and found that port mirroring apparently does not work the same in the 1820 as it did in the 1800. With the 1800s you can make the destination port a port with a linux box attached and then shell into Linux box and monitor the traffic realtime with tcpdump. With the 1820 you are apparently locked out of the destinaion so you cannot connect to the Linux box. Am I just missing something in the way I am configuring the 1820? Is there away around it?
I've just bought a HP 1950-48G-2SFP+-2XGT Switch (JG961A) and would like to monitor CPU utilization and memory usage using SNMP, but I can't find the HP MIB download?
I've searched here to no avail:
https://h10145.www1.hp.com/downloads/SoftwareReleases.aspx?ProductNumber=JG961A
Could anybody provide me with the MIBs please?
After years of managing switch by switch i´d like to make my job a little bit easier be using stackable switches as i now it from my time with 3com 3300 switches. As i have already found there are no other connections than ethernet for higher bandwith but making configuration easier would be help enough and as is read the manual that feature is supported by the 1910 family.
So i enabled the stacking on my main switch, an 1910-48 with Software Version 5.20 Release 1513P99 by defining the private net ip 192.168.1.1 with mask 24 (my homenet has 192.168.74.0/23) and enabled then the build stack feature. Next step was to define port 9 that connects to my 1910-8 with same software release as stackport.
As i understand the last step i have to do is enabling the uplink port 8 on my 1910-8 and than the stack configuration should start, but the only thing happing is that i can´t reach my 1910-8 any more with it´s managemend ip which is shown when i see under summary when connecting with the serial connection cable.
Has anybody already such a stack and has an idea what i´m doing wrong?
Best regards from germany
