HP V1910 VLAN help

rlkcpo — Thu, 17 Sep 2020 14:21:18 GMT

I am new to networking and am trying to find a way to setup some VLANs in this configuration:

Port 9/10 - VLAN 11

Port 11/12 - VLAN 22

Port 13/14 - VLAN 33

Port 15/16 - VLAN 44

Port 7 - VLAN 99

VLANs 11/22/33/44 are fairly straight foward. However VLAN 99 is giving me some trouble. I want the linux machine on port 7 to be able to communicate to the linux machines connnected to ports 10/12/14/16. Seems like this should be fairly simple but I have not been able to find a solution yet.

Thank you very much for any help.

Hi,

Create VLAN:

Network-->VLAN-->Create-->VLAN ID's --Enter VLAN numbers then click create
You can add description as well for the selected vlan's
Finally click on apply then save.

Adding VLAN's on interfaces:

Network-->VLAN-->Modify Port-->

Select the port
Enter the VLAN ID and select Tagged(Trunk)/Untagged(Access) port.
Finally apply then save it.

You can refer user guide from below link for VLAN creation and inter vlan routing (IPv4 static route, pg.273)

Thanks!

So is the only way to get one VLAN to talk to another on the same switch is through static IP routing?

What would I enter into the "Next Hop" field when creating the static IP route?

Im going to attempt to clarify what I am trying to accomplish.

There are 5 separate VLANs on the switch. 11,22,33,44, and 99. I have a PCs connected to port 7, 10,12,14,and 16 and external devices connected to 9,11,13,15. I want the PC connected at port 7 to be able to communicate to the other PCs(ports 10,12,14,16) and vice versa. However I do not want any communication to happen on ports 9,11,13,15 unless it comes from the PC within that VLAN (so the PC connected to port 7 should not be able to communicate with the devices on 9,11,13,15).

I have tried configuring port 7 as a trunk with ports 10,12,14,16 tagged. I have tried seting up interfaces and defining routes but I when creating routes I cannot use an interface as the next hop.

Hi,

Intervaln routing is enabled by default in a switch. So VLANs can communicate with in the switch.

If port 7 as PC coneected then it should be an access port and a particular VLAN allowed.

Are external devices connected to 9,11,13,15. are part of any VLAN: 11,22,33,44, and 99.

I believe external devices won't communicate without routing.

Thanks!

Yes the devices connected to 9,11,13,15 are part of VLANs 11,22,33,and 44. VLAN 99 is a separate VLAN with only port 7 on it.

Hi,

Intervlan routing is enabled by default within the switch. PC will communicate with each if they are the part of same switch.

What are those external devices on 9,11,13,15?

Are they switches?

Thanks!

You say that intervlan routing is enabled and that PCs in different VLANs will communicate with each other as a default state. Im here to tell you that isnt the case. After creating a single VLAN, by design they wont talk to anything outside its own VLAN. So I am really confused by your reply. Let me reiterate for a 3rd time what I need to do. Can you replicate please and post your findings here?

VLAN 11- Ports 9/10- Port 10 has a PC attached to it and port 9 has a raspberry PI on it.

VLAN 22- Ports 11/12- Port 12 has a PC attached to it and port 11 has a rPI on it.

VLAN 33- ports 13/14- Port 14 has a PC attached to it and port 13 has a rPi on it.

VLAN 44- ports 15/16- Port 16 has a PC attached to it and port 15 has a rPi on it.

VLAN 99- port 7 - Port 7 Has a PC on it.

I need the PC on VLAN99 (port 7) to communicate with the PCs on ports 10, 12, 14, and 16 and NOT the raspberry PIs on ports 9,11,13, and 15.

From a factory reset switch how do I accomplish this?
