Basically, you need to make up your mind which device your clients should use as default gateway: the OPNsense - then inter-VLAN routing goes that way, too - or the L3 switch, that in turn uses the OPNsense as default gateway. If you use the OPNsense for inter-VLAN routing, you set up firewall rules for which connections are permitted. Note that the OPNsense ...

Now they have 230 devices and They are going to increase device count by 100. Within the same subnet? Then you'd have to supernet that subnet to e.g. 192.168.24.0/23. I cannot change subnet and increased usable IP addresses count because there are many dependencies. Adding another subnet/VLAN is a better option anyway. As Jesse's already answered, that ...

Questions about protocols above layer 4 are off limits here, however, as a very basic explanation on a layer 2 and layer 3 level, you cannot have multiple VLANs using the same DHCP pool (same subnet). Each VLAN would need a separate DHCP pool (separate subnet) to assign addresses from. For example: VLAN 100: 192.168.1.0/24 VLAN 200: 192.168.2.0/24 Just to ...

you could add a second range to another vlan. If the switch is a layer 3 switch, it shouldn't be a problem to connect to eachother. If not, a downtime is necessary to adapt the existing one.

First- as many others PT is not IOS and many functions are either limited or do not work. Second: Cisco defines two privilege levels by default (1 and 15) any non-default privilege level can be defined with privileges set. You may be able to view the configuration by using the command “show run all” but I doubt the command works. For more reading please ...

Short answer: Do NOT use hybrid mode. If you're after mixed tagged/untagged VLAN trunking, that's not what hybrid mode means. Hybrid mode is used with protocol-based VLANs. Without proper configuration, frames all end up in the default VLAN. The only common use case for hybrid mode is a legacy end node that doesn't support tagging but where you still want to ...

Incidentally, I stumbled on a likely explanation for the described problem. Your suspicion is most probably correct: the switch does seem to verify the firmware version in the config with the actually running version. When exported using the add-ignore-tag option, the first line is changed to e.g. ; J9850A IGNORE Configuration Editor; Created on release #KB....
