No network traffic passing for specific network range on switch
Hi guys
I have an HP network 1820-48G J9981A switch. We have a 192.168.10.0/24 network range on this switch. It has been set with a 192.168.10.10 IP. Prior to this, our network switch was completely vanilla and had no IP configurations.
Now, majority of appliances plugged into this network are on the 192.168.10.0/24 range. However, we have 7-8 devices set to 192.168.9.0/24 range. So now, we are completely unable to get to anything on the 192.168.9.0/24 IP's, as the switch is currently only seeing the 192.168.10.0/24.
My question is, what's the best way now to configure this switch? I don't want to reset it to factory default as we won't have any management. So do I set up VLAN's on all ports? How would you do it?
Or, can I set routing on the switch to say anything on 192.168.9.0/24 network needs to be forwarded on to the 192.168.10.0 gateway?
Thanks for helping

The switch is already connected to a router which has a gateway of 192.168.10.1 and 192.168.9.1. But, old switch was vanilla, so traffic from both networks passed through.
Now that switch has a 192.168.10.0 management IP, it won't route any of the 192.168.9.0 traffic to the necessary gateway.
Should I reset the switch to factory default remotely?
Thank you

3rd option. If the router has an interface configured in each subnet, just connect the associated ports on the switch to the router and assign those ports to the vlan that the router interface is in.

So it looks like a reboot on the switch got us to access some of the network devices on the 192.168.9.0 network. The rest look like they are suffering from application related issues.
Looks like it's been a false alarm. Thanks for your help.

A switch routes traffic between two or more ports. A router routes traffic between two or more networks.
192.168.9.x and 192.168.10.x are two different networks. You'll need a router to route traffic between the two.
