Netgear GS308EP
I'm having the same issue as decribed in: https://community.netgear.com/t5/Insight-Managed-Smart-Cloud/Can-t-reach-GUI-on-GS308E-over-VLAN-trunk-port/td-p/2291953 But what's puzzling to me is....

When the same is not the same,,, Appears fellow BrianL was responding correctly to the thread referred.
Most of these Plus switches like the GS308EP are built on unmanaged cores with tiny uC added to implement the NSDP Protocol (for the legacy Prosafe Plus Configuration Utility - don't worry, the config options are disabled by default due to a non-mitigatable risk in this L2 protocol, only the discovery feature remains active) and the basic IP stack with the http-only Web-UI to configure some of the control bits on the switch.
The uC IP stack does not support tagged, but only untagged IP frames but it does support IP subnetting and (if I'm not wrong) handles the default gateway correct [this is why you see the ACL controls for IP addresses and subnet masks], however does lack of the Path MTU Discovery (PMTUD) [this does deny using e.g. any VPNs or the like, as the uC IP stack does only deal with the complete default Ethernet MTU].
I hope this gives you some of the bigger picture of what you got here with these inexpensive switches..

PS. I'll request a moderator moving this thread to the appropriate Plus And Smart Switches Forum to discuss Smart Switches (T) and Plus Switches (E), including Local and Remote Management

Hi obrennang,
Welcome to the Community!
As described in the above thread, the port 1 is tagged/trunked in both Management VLAN 1 and secondary VLAN 15. Since Port 1 PVID has defaulted to 1, there's no need for tagging it in the said management VLAN. Put it back to Untagged and in the said port the traffic passing through will be both VLAN 1 and 15.
Kind regards,
BrianL
