How to setup L3 routing between VLANs on a 1920S switch

[Ivan_B]

@Ihaqueit 1920s doesn't have CLI. Your example is for 2930F switch which runs totally different OS. Irrelevant and misleading

Thanks for confirmation Ivan,

Then please provide the solution regarding L3 routing.

Dear @Ihaqueit ,

Thank you for your kind suggestion and invitation, however my colleague @akg7 is doing great job on this post, I don't have anything to add at this point.

Hello @Koine ,

Apologies for delayed response.

Can you please share a network topolgy diagram, hand drawn is also fine?

Want to see uplink and down line connectivity.

Thanks!

Hello akg7

Today I found ourselves ENABLED to upload images ... I will try to explain, referring to the pictures just posted (they show the current Switch configuration, as required.)

The first image is a simple network diagram. The LEFT part is the original site network (192.168.228.0/23), with the 1920S switch (192.168.228.93, IP used for management purpose) and the overall gateway (192.168.228.95). Other 1920 switches are not depicted (not relevant here).
In the RIGHT part there is the "new" site network (10.220.243.160/27): we build a VLAN_243 with (currently) 6 UNTAGGED ports on the same 1920S , this VLAN has a 10.220.243.190 IP, also used as PC Gateway for the 10.220.243.160/27 PCs

As explained, both VLANS do work as they were TWO separate switches:  all the PC on VLAN_243 can see each other, they can ping their gateway (10.220.243.190), but they don't reach nor the 192.168.228.93 IP (switch IP on the VLAN_1), nor the rest of the network (the Internet gateway 192.168.228.95)
All the PC on VLAN_1 can see each other, they can ping their gateway (192.168.228.95) and also the 192.168.228.93 IP (the switch management IP on the VLAN_1), but they don't reach nor the 10.220.243.190 IP (switch IP on the VLAN_243), nor the rest of the 10.220.243.190/27 network

Thank you for your help

Hello @Koine ,

So there are two 1920s switches?How both devices connected? IP address between them?

Thanks!

Hi akg7
Sorry, perhaps I'm not so good in drawing
Only ONE switch involved. In the diagram I depicted the "separate" (logical) 2 VLANs, created after the VLAN_243 definition
One switch, 6 UNTAGGED ports (currently 2,4,6,8,10,12) for the VLAN_243, all other ports UNTAGGED in the default (original) VLAN (VLAN_1)
With the dotted lines I wanted to JOIN the 2 logical parts ...

Hope it's more clear now

Hello @Koine ,

Thank You for the information.

And is there L3 switch connected as uplink to this switch?

Thanks!

Hello @Koine ,

Enabling global routing is enough for same switch intervlan routing.

Are these switches are acting as  layer 2 or layer 3?

Thanks!
