the switches are all the same, i moved all the hardware from one rack to another. the only thing changed is the rack it self.

forgot to post this.

i made some progress and narrowed it down to only UDP traffic being borked, i can send icmp across vlans but sadly still stuck. i wonder if anyone with a technical skills then i got can help me troubleshoot. i used mostly interface diagnostics to get to where i am based on Monviech's suggestions. thanks in advance.

tcpdump from opnsense for the vlan tested is blank, i have run it a few times and get 0 hits. tried to dump tcp and any.
tcpdump from test machine, cant find anything odd here. just seem like linux is trying to send a request on the network to get an ip.

i tried to exclude the switch as a variable i spun up a vm connected directly to the vlan network.

the vm doesnt connect to the network. why i know its an opnsense config is because that vm has the same connection issues as the rest being plugged in directly to the network. i also included the logs, maybe im just not seeing something...


i tried to ping the vlans from the lan ip and the packets seem to be going through.

the switches are all the same, i moved all the hardware from one rack to another. the only thing changed is the rack it self.

the hardware is all the same. i fear the only thing that might of changed is i might of forgotten to write mem on the switch but i went through the ports and they all seem to have the same config. i can post the logs or settings but im at a complete loss as to whats going on or how to trouble shoot it.

edit:
i should also mention that before i moved everything i labled everything so all cables went back to thier respective ports.

Hey everyon, apologies if this is the wrong section or format. i have been looking for a solution sifting through the forums and google for the better part of the day. Everything was working well 2 days ago, last night moved my servers to a new rack and reconnected everything. same ports same configs. however after everything came back online, no devices on vlans are pickup IPs. i have looked through the logs and:

2024-01-08T00:56:50-05:00 Informational dhcpd Listening on BPF/vtnet1_vlanxxx/xx:xx:xx:xx:xx:xx/xx.xx.xx.xx/24

ths loop is also exactly the same on the other vlans. i have checked the dhcpd serivce and its working correctly on the main network and seems to be up and running. on the vlans however its radio silence.

i have tried to recreate some of the vlans, connect with and without wifi, create a vm on the router to directly attach it to the vlan. im a bit at a loss as to what it could be. if anyone has some suggestions or can help out i'd greatly appreciate it.
