MSM 317 untag problem

Hi all,

There is a problem happening in our environment.

All of our switches connected to msm317's port are configed as untag to vlan 2040, but also tag vlan 1.

Our DHCP servers are located at vlan 1.


However, even they are all untagged at vlan 2040, some of them are still get assigned vlan 1 ip address.

Is there any method to prevent this situation?


I know we can no tag vlan 1 on that port.

But with some situation, we have to allow them to communicate with vlan 1.


Any recommendation would be appreciated.
