HPE OfficeConnect Switch 1920S JL384A ARP Proxy

February 25, 2019, 12:12 pm

Hello, I am new to HP (networking too) and trying setup 1920S switch so pardon me if I ask what I supposed to know.

We own ancient Siemens PLCs with no option of setting gateway. The network setup consists of Kerio Control and one 1920S. I need to access the PLC from VPN client connected to Kerio Control.

I believe that 1920s is supposed to be able to use ARP proxy. But what I read about 1920s seems to be able to ARP proxy only in betwen subnets set directly on the unit. Is that right or is there a chance to make my configuration work?

I must access IP 10.10.10.1 from IP 192.168.124.10. Thanks much for sending me the right direction.

Configuration:
- Kerio Control VPN Client 192.168.124.10
- Kerio Control VPN server 192.168.124.1
- Kerio Control LAN VLAN10 10.10.10.224
- unit 1920s
      routing->configuration->global routing enabled
      routing for VLAN10 enabled and set IP 10.10.10.10, ARP proxy enabled
     default fateway set to 10.10.10.224
PLC 10.10.10.1 (no gateway)

Odd STP related problem in V1910 with a stacked switch

February 23, 2019, 4:51 am
$

0
I have a very straightforward network to deal with, a central switch made up of two stacked Edgecore ecs4510-28F switches feeding 11 V1910-48G switches.
The feeds are dynamic, LACP controlled, LAGs of 4*1G fibre SFPs
At the V1910 end the LAGs are made up of ports 49-52.
At the Edgecore end the LAGs are made up of two ports each from each stack half, e g port1+2 in switch1 + port1+2 in switch2.
The topology is a simple and straightforward star, the 4*1G LAGs connect each V1910 directly to the 4510 stack, and there are no other links between switches. The V1910 rj45 ports connect to individual flats, and the risk of a loop to appear between two flats seems minute, even with Apple style ethernet bridges and wifi leakage.

Now to the problem:
If I enable STP on the MSTP global configuration page in more than one V1910, all but one V1910 will eventually be cut off from the 4510stack.
All I do is enable globally, and all else is default.
What could possibly cause this?
There are no superfluous links, and the topology will never change, but I'm still uneasy about turning STP off, which would, I suppose, solve the problem.
What would be your first thought in a situation like mine?

HPE 1950 10gbase-t only stacking

Hello everyone,

Apologies for the very basic question but haven't found an answer in the user manual or in other topics in this forum.

I am simply wondering if the 10gbase-t ports are supposed to be used for stacking only or if I can use them as normal ports as well (and thus connect to anything like a NAS or computer, in case my question wasn't stupid enough :) )

Many thanks to anyone willing to take the 30 seconds to answer this

V1910/JE009A: Using ACLs as a poor man's IP Source Guard

May 19, 2019, 11:50 pm
$
0
0
I want to set up a basic ACL or set of ACLs to
Permit source addresses in the range 10.0.28.1 to 10.0.31.254 to enter a port range.
Permit DHCP DISCOVER packets, that have the source address set to 0.0.0.0, to enter that same port range.
Deny all packets with other source addresses inbound access on that same port range.

Because most of the people looking after this network are very uncomfortable with CLIs, I really want to be able to do that in the Management Web GUI.

But I have so far been unable to do this in the GUI: In the CLI I seem to have gotten it to work with a single basic three-rule ACL and then that as a packet-filter on a port.

Help!

I hope someone can help,
We have 5 x HP 1820 switches connected via Trunk on each using the SFPs, Recenetly we put a HP 1920 in front of a 1820 due to needing more connectivity, However this 1920 will not connect to our Dell N2048 using dual SFP on a trunk, as soon as its connected (Both SFPs) the network storms and crashes.
I Do have the 1820 sat behind the 1920 using Trunks on Ports 51 and 52 and that does allow communications.
I need ports 49, 50 to be a Tunk to our Dell with VLANs 1, 10, 20, 30 which is currently setup for ports 49 - 52.

Can Anyone help?

HP V1910-48G switch ports of aggregation group become INACTIVE

June 19, 2019, 10:24 pm

On our V1910 switch we have observed intermittent network disconnections.

Based on the log file, the ports with the highest number of network disconnections (indicated with "link status is DOWN") were 4 ports (Ports 9, 30, 31, 32) that are members of a static aggregation group identified as BAGG9.
In the logfile, the following message is recorded for Port 9 (Similar messages appear for ports 30,31,32):
"Port member GigabitEthernet1/0/9 of aggregation group BAGG9 becomes INACTIVE, because the port's configuration is improper for aggregation."

We have checked our configuration and found that the 4 ports have the following settings:
•802.1X protocol is disabled
•Handshake is enabled
•Periodic reauthentication is disabled
•The port is an authenticator
•Authentication Mode is Auto
•Port Control Type is Mac-based
•802.1X Multicast-trigger is enabled
•Mandatory authentication domain: NOT configured
•Guest VLAN: NOT configured
•Auth-Fail VLAN: NOT configured
•Max number of on-line users is 256

Which of these settings is "improper for aggregation"?

Hi All,

i have recently bought and deployed 3x JG963A-OC20- HPE 1950 48G 2SFP+ 2XGT POE+ SWITCH 'S

and the primary switch in the stack ( first switch configured and deployed. also has the most occupied ports) is not responding properly.

 

when i enter the ip address in a webbrowser (used opera,chrome,Internet explorer. across multiple machines)

the web UI comes up blank or with a password reset screen in plain text.

Any help on how to fix this issue would be much appreciated.HPE switch Issue.PNGHPE swtich UI.png

ProCurve switch disorder

June 29, 2019, 1:18 am

Good day,

I have the feeling that yesterday one of our HPE ProCure switches (or the backplane) in the rack hung up.

Possibly also by some dust and there by 26 degrees room temperature?! Where the 26 degrees room temperature but within the specifications.

Can it really be that the switch just hung up?

Symptom was:

- ping response time at about 1 to> 1ms when the goal is reached, but every 5th or 10th or 5th ping, so irregular, was no longer answered (no answer).

Problem occurred quite suddenly, without any connection.

When we changed the port, the responses to the ping were again reliable / constant and also the ping response time again at about 1 to> 1ms, but the target is reliably reached again (on another switch).

What alternate HPE switches could be used instead of unmanaged HPE ProCure to monitor with HPE OneView? It makes sense to swap 3 switches, because they may have hung up spontaneously one time after a long time or again the above question: Can it really be that the switch just hung up?

DL

---> Translation to german language:

Guten Tag,

ich habe das Gefühl, dass sich gestern eine unserer HPE ProCure Switches (oder die Backplane) im Rack im Büro eventuell aufgehängt hat.

Eventuell auch durch etwas Staub und dabei 26 Grad Raumtemperatur?! Wobei die 26 Grad Raumtemperatur doch innerhalb der Spezifikationen liegen.

Kann es wirklich sein, dass sich der Switch einfach mal aufhängt?

Symptom war:

- Ping-Antwortzeit bei etwa 1 bis >1ms, wenn er das Ziel erreichte, aber jeder 5. oder 10. oder wieder 5. ping, also unregelmäßig, wurde gar nicht mehr beantwortet (keine Antwort).

Problematik trat ganz plötzlich auf, ohne irgendeinem Zusammenhang.

Als wir den Port wechselten (auf einen anderen Switch) waren die Antworten auf den ping wieder zuverlässig/konstant und ebenfalls die Ping-Antwortzeit wieder bei etwa 1 bis >1ms, jedoch wird das Ziel wieder (an einem anderen Switch) zuverlässig erreicht.

Welche alternativen HPE-Switche könnte man statt ungemanagter HPE ProCure verwenden um diese mit HPE OneView zu monitoren? Macht es sinn 3 Switche auszutauschen, weil sich eventuell einer mal nach langer Zeit spontan aufgehangen hat bzw. wieder obige Frage: Kann es wirklich sein, dass sich der Switch einfach mal aufhängt?
