I am trying to assign the shown VLAN configuration to my UbiSwitch with the updated firmware. The ports assigned to single VLANs work fine untagged but when I try to assign multiple VLAN IDs to ports 4 and 5 they are only able to ping VLAN 30 ports.

Hello Jacob,

It looks like you are trying to configure port 4 and port 5 as trunk ports rather than access ports. Can you outline what commands you use to configure the VLAN topology on the switch?  
For reference, we have [a guide in our docs](https://botblox.notion.site/VLANs-de56fc3a7a174cfe92716d1eb032c901) for configuring trunk and access ports for VLANs.

I have configured it with the following commands and tried ping testing between ports and I am seeing no response from ports 4 and 5 for any VLAN @aaron

Thanks,

Could you show me packet captures on the test devices you are using to try to ping each other? You can use [wireshark](https://www.wireshark.org/) or [tcpdump](https://www.tcpdump.org/index.html#documentation) for this.

In particular, I’m interested in seeing devices on port 4/5 being pinged by devices on access ports (i.e. any other port).

Could you also show how you’ve configured VLAN network interfaces on the test devices?
